Why perturbation theory remains paramount

Breaking news: Jim Parsons wins the Television Critics Association's 2009 award in the category of highest individual achievements in comedy. Congratulations to my imitator!
What is the method

Perturbation theory is an approximate method that describes a physical system in terms of a similar, simple enough, solvable, and often non-interacting physical system, "H_0", and a small perturbation of this system, "lambda V".

If you assume the letters to represent the Hamiltonians, or the formulae for the total energy (and evolution) of the systems, the total Hamiltonian is
H = H0 + lambda V.
Here, the perturbation, "V", is normalized in such a way that it is comparable to "H_0". On the other hand, "lambda" must be smaller than one. Ideally, it should be much smaller than one.

While "H_0" may be solved exactly, the full "H_0 + V" cannot. But there exist sophisticated mathematical techniques that allow us to quantitatively answer any question about "H" by calculating appropriate Taylor expansion in "lambda". We are continuously moving from "lambda=0", which corresponds to "H_0", to the actual value of "lambda", which corresponds to "H".

Historical successes

Centuries ago, such techniques would be used e.g. for the calculations of the Earth's orbit under the influence of other planets such as Jupiter. The influence of the Sun had been known since the victorious achievements due to Kepler and Newton: our star directs the planets to move along exact ellipses. The attractive force from the other planets may be added as a perturbation. The first nontrivial term in the perturbative expansion is usually everything you need.

Not only the influence of Jupiter but even the effects of Einstein's general relativity could have been added as perturbations to the simple Kepler system that was solved by Newton using his (or their) newly developed differential calculus. Einstein was able to predict the precession of Mercury's perihelion. That's quite a general lesson: the predictions of a new, more accurate theory for a familiar situation can often be expressed as the old, approximate theory with some new perturbations being added.

Perturbation theory became even more important with the boom of quantum mechanics. It has been used to calculate the spectra, cross sections, and many other things. Quantum field theory has really escalated this process because perturbation theory became the main technical procedure, the key "routine", behind most of the calculations. Feynman diagrams became the ultimate symbol - and the main actual tool - of perturbation theory in quantum field theory.

The perturbative method is playing a similar role in string theory, too. For quite some time, it has actually been the only method how to calculate things in string theory (via the stringy Feynman diagrams, i.e. the Riemann surfaces representing the joining and splitting worldsheets). I will postpone the discussion of the last 15 years - which were dominated by the "nonperturbative research". But before we get there, we must understand the limitations of this method.

Why perturbative expansions are not the whole story

Many functions, including "sin(x)", "exp(x)", "sqrt(1+x^2)", and many others can be written in terms of power law expansions, i.e. Taylor series. These expansions converge to the desired result. You might think that it is a general fact: the correct answer may always be obtained arbitrarily accurately if you sum a sufficient number of terms in the Taylor series, at least if you're within the convergence radius.

However, this proposition is untrue. Equivalently, it is strictly speaking true but the convergence radius is typically zero in quantum field theory and string theory. If you want to know some terminology, which is really nothing else than terminology, such divergent Taylor expansions are called asymptotic series. Why do they fail to converge to the right result?

First, consider e.g. the function "exp(-1/x^2)". Clearly, it is very small if "x" is small because "x^2" is small and "-1/x^2" is large and negative, producing a tiny exponential. We define the function to equal zero at "x=0", in order for it to be continuous. However, the function is clearly nonzero for all other values of "x".

Now, let's try to calculate the Taylor expansion. The function itself vanishes at "x=0". What about its derivatives? Well, if you think for a while, the "(N-1)th" and "Nth" derivatives will keep the exponential factor but they will be adding various ratios of polynomials in front of the exponential. But near "x=0", the exponential goes to zero faster than any powers of "x" can go to infinity, so it will win in the product: the "Nth" derivative vanishes at "x=0" for every "N"!

In other words, the Taylor expansion of the function is "0+0x+0x^2+...". It is zero even though the exact function is clearly not.

Divergences in QFT and ST

The second point we mentioned is that the convergence radius is typically zero. Why? Imagine that you have a quantum field theory, such as the "lambda phi^4" theory with a scalar quartic self-interaction in "d=4", and you compute the Feynman diagrams at "L" loops.

One can see that the number of diagrams with "L" loops will be close to "L!" times subleading factors. So the coefficient of "lambda^L" in the Taylor series will be dominated by the factor of "L!" which diverges faster (for very large "L") than the speed with which any "lambda^L" can suppress it. Recall that by the Stirling formula, "L!" is close to "sqrt(2.pi.L) (L/e)^L", and the factor "L^L" is what makes it larger than ordinary powers or exponentials.

(The number of diagrams goes like "L!" in any dimension. There are also integrals over the momentum space inside the L-loop amplitudes. Their behavior and/or renormalizability depends on "d" but in this discussion, we are interested in the "combinatorial factors", purely numerical coefficients that don't depend on "d" and that are actually more important for the "extremely large L" behavior.)

However, you may consider a small value of "lambda" and try to achieve the maximum accuracy in your computation of the amplitudes: sum all the initial terms of the Taylor series, up to the minimum one (where they start to blow up again, because of the growing "L!"). It turns out that the minimum term is roughly the "Lth" one where "L=1/lambda", and this term is comparable to "exp(-C/lambda)" where "C" is a constant. You don't know exactly whether you should still add this smallest term (and the next one) or not, so "exp(-C/lambda)" is the minimum error you will have.

Note that "exp(-C/lambda)" is very small. Asymptotically for small "lambda", it is smaller than "lambda^L" for any fixed exponent "L". And this estimate, "exp(-C/lambda)", is also the magnitude of the largest nonperturbative contributions to the same quantities. In the case of the scalar quartic self-interaction, nonperturbative physics is actually ill-defined, as we will explain.

However, the previous paragraphs may be applied to pretty much every coupling constant in quantum field theory and string theory. You must be careful what "lambda" means because in many cases, it means the squared coupling constant. But once you do the map properly, you get the right estimates for the high-loop coefficient as well as the nonperturbative terms.

The correct "lambda" should be compared to the following functions of coupling constants in important theories:
lambda quartic scalar ≈ y2Yukawa ≈ e2QED
≈ g2Yang-Mills ≈ g closed string ≈ g2open string
This uniform treatment of scalar couplings, Yukawa interactions, gauge theories including QED, open strings, and closed strings is just about a style of presentation (due to your humble correspondent) that unifies your reasoning about all the cases.

You can see that in gauge theories, the leading nonperturbative corrections are predicted to be close to "exp(-C/g^2)", matching the effect of solitons (such as magnetic monopoles) and instantons (in some sense, loops with monopoles). In string theory, the winners are close to "exp(-C/g_{closed})" which corresponds to D-branes and D-instantons, as expected from the "(2L)!" behavior of the L-closed-loop diagrams.

This function of "g" looks greater than the result in Yang-Mills theory - and people often say that the stringy nonperturbative effects are "larger" than they are in field theory - but if you realize that "g_{closed} = g_{open}^2", it will have the same form as a function of "g_{open}" as the Yang-Mills result has in terms of "g". With the right parameterizations and analogies, the behavior is universal in field theory and string theory. In the same way, the "(2L)!" behavior for the L-loop closed string amplitudes looks "more divergent" than "L!" in field theory. But you shouldn't forget that "L" closed-string loops are equivalent to "L' = 2L" open-string loops, so the behavior is fully analogous if you want to see the analogy.

(A mystery seems to arise for heterotic strings, but let's not discuss it here.)

You should understand that the divergent character of the perturbative expansion doesn't imply that the full exact function doesn't exist. It does exist and it is finite but it just can't be quite accurately expressed as a Taylor series. Still, the Taylor series becomes extremely accurate for weak coupling. You can check all these statements by taking specific examples.

Perturbative success of QED

Quantum Electrodynamics (QED) was the first successful quantum field theory, developed since the late 1920s, and it remains the most accurately tested theory in the history of science. If you use the natural (quantum relativistic "c=hbar=1") units, the interaction is determined by the fine-structure constant, "alpha=1/137.036..." which plays the role of "lambda". That's a pretty small number that makes the perturbative expansions very potent.

The single most accurately verified prediction is that of the magnetic moment of the electron. The coefficient "g/2" was measured by Gabrielse et al. in 2006 to be
g/2 = 1.001 159 652 180 85 (76).
The error is just 0.76 parts per trillion (I mean the American trillion which is modestly called "bilion" in languages like Czech). Moreover, the result may also be obtained theoretically and they match, within the error margin. In fact, the accuracy is on the verge of discovering some discrepancies that should be there because of the new physics near a TeV.

The theoretical calculation leads to a Taylor series in "alpha" which looks like "1 + alpha/2.pi + harder terms": the "alpha/2.pi" term has been known for more than 50 years. All these things are calculated perturbatively while the nonperturbative terms are completely neglected: that can't spoil the huge accuracy. Why? Because "exp(-1/alpha)" is "exp(-137)" which is close to "10^{-60}", so even once you realize that it shouldn't have been "1/alpha" but "C/alpha", you're still safe.

Clearly, nonperturbative effects become important if the coupling is larger. And if it is very large, they qualitatively dominate the physical phenomena. Perturbation theory loses the steam once the interactions become of order one. For example, QCD perturbation theory is the right answer for high-energy QCD effects while you need different methods to study long-distance physics such as the interactions of protons and neutrons in the nuclei (AdS/CFT is among the helpful tools here).

Mysterious strong coupling limits

For a weak coupling, the nonperturbative effects may be nonzero but they're so tiny that you don't expect them to change the qualitative features of the physics (and not even the measurable quantitative ones). But as the coupling is getting large, you might expect very mysterious things to happen.

In the past, people knew nothing about the nonperturbative or strong-coupling behavior of many field theories and vacua of string theory. And if humans don't know something, this something is full of sea monsters, dragons, extraterrestrial aliens, and nearly infinite water falls falling at a huge turtle.

However, when Christopher Columbus sailed to His India (now known as America), he found something completely different and more familiar.

Also in physics, the research has actually shown that if a theory is well-defined in the first place, its strong coupling behavior simply can't be completely new, unusual, or mysterious. The strongly coupled regime may be far from your starting point but it is just another place that must obey the laws of Nature (and logic). The physical phenomena over "there" are as sensible as those you could expect "here". And the strongly coupled limits of many theories are actually equivalent to some other (or the same) well-known weakly coupled theories.

S-duality and the Atlantic Ocean

Let me return to my metaphor from the era of Christopher Columbus. The oceans that were far from Europe could have been thought to be full of mysterious objects. But Columbus' discovery has reduced the mystery of the Atlantic Ocean. Europe and Africa are on one side while America is on the other side. One can get there from the continents which reduces the living space for mysterious monsters.

Don't get me wrong: there's still a lot of water in the ocean and it's hard to swim to the middle of it. But because it's known to be surrounded by known continents, it can't be too mysterious.

The situation is similar in quantum field theories and in the moduli spaces of string theory. For a very large value of "g", many of them were found to behave exactly as another (or the same) theory whose coupling constant is chosen to be "1/g" which is small: a weakly coupled theory. I don't want to go into details here. But it turned out that the "g=infinity" limit must be thought of as being analogous to the "g=0" limit. And this analogy is often an exact equivalence.

Whenever the "S-dual" description is found - another theory that is indistinguishable at "1/g" from the original theory with the coupling "g" - the true mystery is expelled to the middle, near the "genuinely strongly coupled" points such as "g=1". But the "g=1" region can't be that different from "g=0" or "g=infinity" because it's pretty close to both, if you use the right metric: you can get there by your "ships", namely the perturbative expansions that start at "g=0" or "g=infinity" (the continents).

Perturbative expansions lead to qualitatively correct physics

What's important is that the "vicinity of Europe" (the small "g" region) can be understood in terms of objects that are known in Europe, i.e. that you can identify at "g=0", and the European laws (how these objects interact near "g=0"). The same comment applies to America and "g=infinity".

There are no "huge" regions of the Atlantic Ocean that would be completely inaccessible both from Europe or Africa and America. So even if you don't know the precise results, including the nonperturbative corrections, you're pretty much guaranteed that you qualitatively know the physics. And in many cases, you can even add some "transperturbative", i.e. well-defined nonperturbative terms that give you more accurate results than the perturbative expansion (which remains the first part of the full result).

Joe Polchinski's D-brane calculus extends the perturbative expansions of string theory in the same way as ordinal numbers generalize the concept of integers (the ordinal numbers may be identified with the powers of "g", and "g^omega" is a symbol for the D-brane factor "exp(-C/g)": my analogy/map). D-branes are surely heavy, non-perturbative objects and D-instantons are tiny effects at weak coupling. On the other hand, all their properties are determined by perturbative calculations involving the good old perturbative objects, the strings (in this case, open strings with new boundary conditions).

Other nonperturbative methods

Besides S-dual descriptions, there are many other methods that have allowed us to study nonperturbative physics - including lattices and RG flows in the space of theories. It is fair to say that all these checks have confirmed the general statements above, especially the proposition that the qualitative conclusions of the perturbation theory should be trusted if the coupling constant is weak.

Since the mid 1990s, the duality revolution in field theory and especially string theory has expanded our knowledge of nonperturbative physics considerably. Most of the conceptual stringy papers since 1995 have been concerned with nonperturbative phenomena, in one way or another.

But one thing surely hasn't happened: the perturbative approximations to many questions have not been proved wrong. In fact, we have seen quite the opposite outcome.

Nonperturbative physics is just a refinement of the perturbative method and the main lesson that the nonperturbative insights have given us is that physical phenomena that admit familiar perturbative expansions are also relevant for the extreme regions that were thought to be full of dragons and sea monsters. In typical theories, America (the "g=infinity" region) has become another continent analogous to Europe. In its vicinity, one can do the usual things that you can do near the continents, e.g. to swim (and calculate scattering amplitudes as Taylor series).

Landau poles

But not all theories can be extrapolated to define meaningful and exact full theories that also cover the strong coupling. The progress in the Renormalization Group has clarified most of these questions.

Nonrenormalizable field theories, such as Fermi's four-fermion interactions, quantized pure Einstein's general relativity, or all stable relativistic field theories with a well-known type of an interacting Lagrangian above "d=4", admit infinitely many possible higher-derivative terms. Any choice of their coefficients is a priori as good as any other. There's no general way to pick the right values, so the theories always contain infinitely many unknown continuous parameters. All of them matter but you can't measure infinitely many numbers. The theories remain permanently unpredictive concerning any detailed physical questions about the regimes where the coupling is strong.

Renormalizable theories are different: they can actually be extrapolated up to the extremely high energy scales where they're still consistent. The requirement of consistency - and finiteness of the coupling constants - at these very high energy scales determines all the unknown parameters, up to a finite number of exceptions. Once you measure a couple of masses and couplings, you can predict everything, at least up to small errors of order "(ExperimentEnergy / HighCutoffEnergy)^k" with some positive exponents "k".

String theory which can never have any short-distance divergences has very different mechanisms that do a similar job - and that actually determine all the non-dynamical continuous couplings that would look adjustable in the field-theoretical approximation.

But let's return to quantum field theory. There are renormalizable and non-renormalizable theories. Theories with dimensionless constants - including Yang-Mills theory and the scalar quartic self-interaction in "d=4" - are either marginally renormalizable or marginally nonrenormalizable. What does it mean?

Because the coupling constant is dimensionless, you wouldn't know whether the parameter behaves as a positive power of mass (renormalizable) or a negative power of mass (nonrenormalizable). It seems to be "somewhere in between".

However, a more detailed treatment shows us that the coupling constant is usually not quite dimensionless. Quantum effects (starting with one-loop diagrams) modify the dimension: the exact dimension slightly depends on the coupling constant which is the same thing as saying that the coupling constant depends on the scale, something that wouldn't happen for exactly dimensionless constants. We say that the coupling constant "runs". It is no longer "somewhere in between": it falls on one side or another (the exactly conformal theories such as the N=4 supersymmetric gauge theory are the rare exceptions).

With this knowledge, you can actually decide in which way it goes. If the "dimensionless coupling" increases with the energy of the scatttered particles, the theory is nonrenormalizable. Even if it only increases logarithmically, the theory will be marginally nonrenormalizable and qualitatively analogous to the nonrenormalizable field theories (such as most of those in higher-dimensional spacetimes).

So it's very important to find out whether an interaction gets stronger or weaker at higher energies. It turns out that Yang-Mills (non-Abelian gauge) theories are the only ones whose dimensionless coupling constant gets weaker at higher energies (if the number of charged matter species is low enough), an insight that has earned some well-deserved money to Gross, Wilczek, and Politzer. All other types of classically dimensionless interactions grow stronger at higher energies.

The latter include QED and the scalar quartic self-interaction. It means that while these theories look completely consistent and renormalizable in the perturbative optics, up to L-loop diagrams with arbitrarily high "L", their exact nonperturbative behavior is analogous to the nonrenormalizable theories, e.g. those in higher dimensions. At the energy scale where the dimensionless coupling gets comparable to "1" or bigger, the theory starts to break down in the same way as the nonrenormalizable theories. However, in the "d=4" marginally nonrenormalizable case, all the dangerous unknown terms (infinitely many of them) are nonperturbative.

That's the reason why you never want the interactions in quantum field theories to grow strong at high energy scales. Non-Abelian gauge theories are the only major class of theories that may be considered acceptable at high energies in "d=4": they're typically asymptotically free, meaning that the coupling goes to zero, or (rarely) conformal which means that the coupling can converge to a fixed nonzero constant.

Theories with any other interactions - QED couplings, Higgs self-interaction etc. - have to break down at a sufficiently high energy scale (and be superseded by some very nice gauge theories or string theory). What happens above this "cutoff" is not determined by the original theory itself, and a better theory - its "UV completion" - has to be found if you want to answer such questions.

For the quartic scalar self-interaction, the coupling may be defined as the probability that two quanta (particles) of energy "E" interact. It can't exceed 100%, if you use this pedagogical definition, so "lambda" is bounded from above if the theory is consistent. Perturbation theory implies that it runs stronger as you increase the energy and this conclusion has to be right if "lambda" is low enough: one can't return to small "lambda" that would suddenly run weaker because we know that if "lambda" is small, it runs stronger. ;-)

The only way how this interacting theory could remain consistent above the Landau pole, the point where you expect the coupling constant to blow up, would be for "lambda" to converge to a finite constant (because of some nonperturbative stabilizing effects). There would have to be a new scale-invariant theory, a new fixed point. In this case, it almost certainly doesn't exist, but even if it did, you couldn't quite see that this fixed point is the "same theory" as one you started with. You needed some new information: you needed to look in a more general space of theories and the RG flows in between them. You couldn't have defined the fixed point theory by a straightforward procedure rooted in the original classical Lagrangian. In particular, you couldn't have put the original theory on a lattice.

Anti-perturbative religion

Everyone who either knows the history of physics or who has actually done some at least slightly important work in theoretical physics (or both) must know how important the perturbative methods actually have been and still are. They have been important in the development of all key theories in physics as well as in their verification.

I have already mentioned that Einstein had to write the planetary orbits in GR as the Newtonian result plus small perturbations, to verify his new, "nonperturbative" theory. But he was far from being the last man who had to use a similar trick. If you (or at least me and DVV) discover the first nonperturbative description of interacting strings (matrix string theory), the appearance of the free spectrum and the leading interactions known from the perturbation theory are the first things you naturally have to check.

For many phenomenological questions whose answers are important, the perturbation theory is the final word. And even if we're trying to find more general, nonperturbative results and principles, perturbation theory is quite universally the main tool that tells us whether we are on the right track.

Without this method, physics would become an unscientific guesswork in the darkness. The perturbative methods are important for simple reasons.

First, because virtually all the progress in physics is gradual and all temporary insights (both about observed phenomena as well as their theoretical generalizations) are approximate; most of the refinements are guaranteed to look like perturbations of the quasi-established theories in the regimes where they have been established as useful approximate descriptions. And physics has developed sophisticated tools that confirm that - and explain why (and when) - the qualitative conclusions of perturbation theory are reliable in the appropriate regions.

Second, a majority of complex enough physical systems can't be solved or understood exactly, so complicated or approximate techniques are necessary, but the network of the solvable or understandable systems inside the space of theories and ideas is dense enough to be relevant in virtually any situation, so the complicated and approximate techniques are pretty much sufficient, too.

So you can be absolutely certain that all the people who are vitriolic about the whole perturbation theory per se, the people who suggest that it should be removed from the main toolkit of theoretical physics, who think that it should never be trusted or that you should even think that the truth must universally contradict the conclusions of the perturbation theory, are simply deluded amateurs, detached from the actual research, regardless of how many other deluded crackpots are praising them.

Yes, I was led to write this essay as a reaction to an irrational anti-perturbative hysteria by one of them and his name was surprisingly neither Lee Smolin nor Peter Woit.

Forbush decreases confirm cosmoclimatology

Recall that cosmoclimatology of Henrik Svensmark and others postulates that the galactic cosmic rays are able to create "seeds" of low-lying clouds that may cool the Earth's surface. A higher number of cosmic rays can therefore decrease the temperature. The creation of the cloud nuclei is caused by ionization and resembles the processes in a cloud chamber.

Apologies for a sign error in the previous version of the first paragraph.



The fluctuations of the cosmic ray flux may occur due to the variable galactic environment as well as the solar activity: a more active Sun protects us from a part of the cosmic rays. It means that a more active Sun decreases the amounts of low-lying clouds, which means that it warms the Earth.

Because the low-lying clouds remove 30 Watts per squared meter in average (over time and the Earth) or so, one has to be very careful not only about the very existence of the clouds but also about the variations of cloudiness by 5% or so which translates to a degree of temperature change.




A systematic effect on the clouds - e.g. one of the cosmic origin - is a nightmare for the champions of the silly CO2 toy model of climatology because the cloud variations easily beat any effect of CO2. Two alarmists, Sloan and Wolfendale, wanted to rule out Svensmark's theory by looking at the Forbush decreases, specific events of a solar origin named after Scott Forbush who studied them 6 decades ago, involving the plasma. However, their paper was incorrect.

In April 2008, this blog published the following relevant article:
Sun-climate link: a reply to Sloan and Wolfendale.
Sloan and Wolfendale complained that no cosmoclimatological signal could have been seen during the Forbush decreases, i.e. short episodes when the activity of our beloved star decreases the amount of cosmic rays reaching Earth. However, Nir Shaviv explained that it should be expected that such a signal is not seen in the averaged monthly data they had used.

In order to see the "tiger in the jungle", using Svensmark's words from a press release
Cosmic meddling with the clouds by seven-day magic
that will be published tomorrow (I am allowed to read it now because my uncle lives in Melbourne which already has August), and in order to separate these clean effects from the huge meteorological noise, one needs to increase the temporal resolution to several days and also cover the whole globe to dilute the effects of local weather.

Newest paper

Tomorrow, on August 1st, 2009, Geophysical Research Letters will publish a new paper by Henrik Svensmark, Torsten Bondo, and Jacob Svensmark:
The People's Voice (summary of the paper)
Cosmic ray decreases affect atmospheric aerosols and clouds (full text).

Svensmark and his collaborators have looked at 26 Forbush events since 1987 (those that were strong according to their impact on the spectrum seen in the low troposphere where it matters): most of them occur close to the solar maxima (in the middle of the 11-year cycles). The observations with a much better temporal resolution imply that the mass of water stored in clouds decreases by 4-7%, with the minimum reached after a nearly 1-week delay needed for the cloud nuclei to get mature. Roughly three billions of tons of water droplets suddenly disappear from the atmosphere (they remain there as vapor, which is more likely to warm the air than to cool it down).

An independent set of measurements has also shown that the amount of aerosols, i.e. potential nuclei of the new clouds, also decreases. All these "strength vs decrease" graphs display a lot of noise but the negative slopes are almost always significant at the 95% level (with one dataset being an exception, at 92%, which is still higher than the official IPCC confidence level that climate change is mostly man-made).

Each Forbush decrease can therefore warm up the Earth by the same temperature change as the effect of all carbon dioxide emitted by the mankind since the beginning of the Industrial Revolution. While you might think that such an effect is temporary and lasts a few weeks only, it is important to notice that similar variations in the solar activity, the solar magnetic field, and the galactic cosmic rays take place at many different conceivable frequencies, so there are almost certainly many effects whose impact on the temperature - through the clouds - is at least equal to the whole effect of man-made carbon dioxide.

The supplementary material attached to the paper includes many rather sophisticated integrals, power laws, and detailed graphs and numerical checks.

Mark Van Raamsdonk: the entanglement glue

Mark van Raamsdonk (UBC Canada) is quite a physicist. After dozens of very solid technical papers, he decided to write a rather deep conceptual essay (if we want to avoid the term "vague speculative fairy-tale") called
Comments on quantum gravity and entanglement (click).
SlavaM originally wanted to promote this article in his own review but finally it's up to me. ;-)

When a technically weak physicist decides to write an ambitious paper about big questions of quantum gravity, she or he usually ends up with a pile of gibberish and pap. You can't take much of it because it makes no sense.

With Mark's paper about qualitative conceptual questions, we face the opposite problem. When I am reading it, I pretty much agree with every word of it. So at the end, one inevitably has to ask what is it that he has written but is not yet appreciated as a part of the lore?

After the second reading, I tend to believe that there's something like that and it's very powerful but I am still not capable to articulate it crisply. :-)

The kind of questions he's asking

Let us begin with the general problems he would like to fully solve by following his program. In string theory, we have learned many quantum mechanical systems that are dual i.e. equivalent to quantum gravity in some appropriate large N limits.

The non-gravitational systems that display such an emergent gravitational behavior are pretty diverse. So the question is
What feature that they share is responsible for the magic of emergent gravity?
In other words, why does the gravitational description emerge? What is universal about the theories or states where a dynamical, weakly curved spacetime emerges?

And Mark would also like to answer all questions about the origin of complementarity, e.g.: Can we associate Hilbert space with limited patches or just "full" spacetimes? What is the link between the Hilbert spaces - and the space of density matrices - for different patches? Do we need to learn some quadratic maps between pure states and mixed states?

The kind of his gluing answer

Fine, so I have described some of his questions by now. What are his answers? If I strengthen and streamline his statements a little bit, he wants to argue e.g. that:
The primordial degrees of freedom may be viewed as non-geometric ones, and even referring to disconnected components of a not necessarily geometric spacetime. Whenever you want to connect or glue these disconnected components of the spacetime, you need a glue. Mark's glue is the entanglement between the pure states in the components.
Now, I can formulate these statements in a nearly equivalent way so that the propositions will look like obvious tautologies. Truly disconnected parts of spacetime are independent rather than entangled. Yes, indeed.

Whenever you want to talk about the distances between two points, which is pretty helpful in geometry, you want the components to be connected. That's right, too. Once you glue two parts of the spacetime, the degrees of freedom in these two parts get entangled as long as you know that the total energy is low. Yes, indeed: that's true even in quantum field theory. The more tightly they're connected (by thick and/or short necks, like if you're trying to minimize resistivity of a system of resistors), the more entangled the degrees of freedom are. Yes, that's true, too.

While it may be hard to find a clearly new or provocative statement, I think that they are written somewhere over there. It's just not easy to pinpoint the location. :-)

Maldacena's eternal black hole

It seems clear that Mark also wants to generalize Maldacena's insights about eternal black holes in AdS spaces that can be described as an entangled state in two different CFTs. The message is simply that:
What looks like a geometric interpolation between two boundaries in the gravitational picture is described as some entanglement in the non-gravitational description (CFTs).
I am sure that Juan did realize that his idea could have been more general but in order to present as solid evidence as possible, he remained modest and talked about the particular eternal black hole geometry only. But it is true that a qualitatively similar phenomenon exists in other contexts, too.

Stephen Hawking's happily lost bet

At any rate, it is fascinating to realize that an eternal black hole in a connected spacetime may be expressed as a linear superposition of many states, each of which describes two disconnected spacetimes. Stephen Hawking was surely thrilled by this observation, too, before he presented his own argument why the information was preserved: at the level of microstates (or microscopic contributions to the path integral), there's no topology change and no event horizon: all these things must arise from the sum over many microstates or contributions (but Hawking wasn't terribly specific about the way how the approximate horizon actually arises!).

I still find it conceivable that a few years ago, when he gave up the bet, Hawking has actually understood something about the information loss paradox that no one else has. But I wish I knew exactly what it was and what is the complete picture.

My universal black hole entropy derivation

In my favorite idiosyncratic universal derivation of the Bekenstein-Hawking (or Wald's) formula, one can obtain the whole black hole entropy from some topology change of the (Euclidean) spacetime. Imagine that you switch from a description where the microstates can be distinguished to an effective description where they can't. This procedure modifies the topology near the event horizon. It caps and/or glues each point at the event horizon: the procedure is similar to in Juan's and Mark's trace over the microstates.

With the deficit angle "2.pi" removed from every point of the event horizon, the Einstein-Hilbert action gets shifted by "2.2.pi/16.pi.G" integrated over the horizon area, i.e. by "A/4G". The path integral gets rescaled by "exp(A/4G)" which can be interpreted as the result of a trace over the "unmeasurable", macroscopically indistinguishable microstates (i.e. indistinguishable in the effective description). That means that their number must be close to "exp(A/4G)", giving us the right entropy.

The argument can actually be generalized to the whole Wald's formula, including the higher-derivative terms in the gravitational action.

Similar issues have been relevant for various discussions of quantum gravity of eternal inflation: does the complementarity principle apply to the bubbles?

Large entanglement must be possible

Mark says that if a gravitational description with a large enough geometry emerges, the quantum mechanical system must be able to develop highly entangled low-energy states. Well, that's surely the case. We essentially require the CFT to have a large central charge and related criteria in order to have a lot of states with low energies (normalized as the dimensions of the corresponding operators in the AdS/CFT context).

But does it tell us anything else? What does it really mean to require that these states may be highly entangled? This is the part of the story I don't understand. Isn't entanglement a universal skill of all quantum systems, a construction that can be used for any Hilbert space? In other words, shouldn't your ability to construct "highly entangled states", whatever it exactly means, depend on the density of states only?

After all, entanglement doesn't care about the interpretation of the states, does it? Moreover, you shouldn't really start with any a priori interpretation of the states in your CFT or a similar theory because an interpretation - the holographic geometric one - is your goal, isn't it?

So I agree that the entanglement may be there and that there are many states whenever new holographic dimensions emerge: but I don't quite understand what is the actual role played by the entanglement.

Pure-mixed maps

On page 3 (PDF: 4 of 30), Mark offers a picture that argues that pure states of a CFT in AdS/CFT may be interpreted as pure states in the full Poincaré patch but also as mixed states in smaller causal patches inside the AdS space. Well, the first statement is rather uncontroversial, except for possible issues about the normalizability of the states (which might however be a damn important technicality for a proper discussion of the relation between different patches!).

The second statement, involving the mixed states, is much more controversial. At least, the nature of the map is controversial. In some sense, one can always calculate a mixed state for a region by tracing over all the degrees of freedom outside the region. At least at the moral level, this is the case. But is such an operation "canonical"? Can we possibly learn something out of it?

In other words, is it legitimate to expect an exact theory of quantum gravity for limited regions of spacetime - or at least for those with the null boundaries of some kind? The answer can be Yes and No. But I have some problems to understand what the Yes answer could mean.

After all, whenever you deal with density matrices (or with tracing over some degrees of freedom, which is a mundane way to obtain density matrices), you talk about situations with incomplete knowledge. A density matrix is no "objective state of affairs". It is a description of the system you're interested in - one in which you assume a certain kind of "ignorance" about everything else.

If you're only interested in a smaller system - e.g. events in a spacetime region - you're always allowed to ignore the rest. So a density matrix for this region calculated from a pure (or mixed) state of a bigger spacetime does the same job.

But isn't it true that you must always be able to see that the world continues even after you cross the null boundaries (either in the past, or in the future) and that your ignorance - i.e. the very reason why you used density matrices - is just your "psychological" problem (and a mathematical trick to overcome the ignorance), not an objective feature of reality?

You may slice your spacetime by lightlike slices and all physical questions depend on the way how objects get from one slice to the next one (think about the light cone gauge). The physical systems on the opposite sides of a null slice may be entangled or related but they're also slightly different, because of the evolution in the other lightlike direction. All the dynamics is hidden in this dependence on the side, so dynamics can't be just about the entanglement.

Spacetime vs worldsheet and flops

It seems that Mark is intrigued by similar fascinating qualitative properties of our functioning descriptions of quantum gravity and sees a similar new general story as your humble correspondent does. But I am afraid that he hasn't still managed to write down the crisp answer that could be followed to answer all the questions about the origin of spacetime, its connectedness, entanglement, complementarity, and so on. And neither have I.

Maybe David Berenstein will? He claims to be completing a super duper important paper. ;-)

There is one more point that Mark doesn't discuss: the application of these ideas to worldsheets. After all, the stringy worldsheet is a consistent (two-dimensional) theory of quantum gravity, so many statements about quantum gravity should apply to the worldsheet, too.



If you open Polchinski's book, volume I, around Figure 9.7, you will see that higher-genus Riemann surfaces can be obtained by gluing two lower-genus surfaces that are connected with a tube. The tube may be represented by the sum of insertions of a complete set of operators at both places.

The similarity with Maldacena's rule for the eternal black hole is obvious: after all, we're solving a problem from the same universality class. But whatever Mark's ideas about the role of entanglement are, do they apply to this picture of the glued worldsheets?

Another question is whether the entanglement of two disconnected portions of spacetime may apply to some "ordinary" types of topology change. I have been thinking about a possible new kind of instability of the non-supersymmetric landscape - a decay of Calabi-Yau spaces with fluxes and branes into pieces (that would guarantee that only the "simplest" compactifications are viable). The entanglement story would clearly apply here, if this decay is possible at all.

But can't the gluing tubes have a different topology than a sphere times an interval? Cannot similar traces - and entangled states - be used to interpret the new branch in the case of well-known spatial topology-changing processes such as the flops and the conifold transitions?

Can Mark answer the question whether a stringy spacetime can actually decay into pieces, and/or absorb a new component that has been disconnected so far? Shouldn't baby universes remain forbidden? Is the process just "infinitely long", as measured by the logarithm of the "length over thickness" of the necks?

Summary

While we know many things and we can smell the flavor of many intriguing ideas, the full general story of the emergent spacetime patches remains an enigma. It may be helpful if every physicist with at least 500 citations for papers linked to holography or microstates in quantum gravity tried to write a preprint with her or his own attack on these questions, just like Mark did.

Maybe, the Nth paper from the sequence, with a finite N, could contain the (almost) complete answer. ;-)

Dear Colleagues,


I take the unusual step of including the first link, researched and written by Keith O’Brien, in its entirety. Interesting and well written. I don't agree with all the content (would I ever?) but it does make some very valid points and is an enjoyable read. On the question of anthropomorphism, I have always believed it to be an important quality of the persona of a good animal person. I believed it forty years ago and still do today. Entertainment....Yes definitely. Nobody but visits a zoo to be educated. Edutainment is the recognised key. Give people a good day out and send them home knowing and caring about something they had not thought about before. The “Russia’s Grizzly Coast” at Minnesota Zoo sounds brilliant. Any exhibit that keeps people for an hour is teaching. Those who watch will care.

I don't doubt the sincerity of the majority of so called 'animal sanctuary' operators because it really is all in a name. They are keeping wild animals captive and are really 'zoos' at the end of the day. It is they that seem to make a distinction and make statements like: "We also provide permanent refuge to surplus animals from zoos and other wildlife facilities, where they face euthanasia due to over-breeding. "Sorry, but I agree with euthanasia. It is part of the management tools to be utilised by responsible zoos within managed breeding programmes. Regardless of how 'planned' a breeding may or may not be there will always be 'surplus'. Surplus passed on to sanctuaries or rescue centres (which are just zoos by another name) is irresponsible. There are only a limited, very limited number of spaces in captivity. They should not be filled with 'useless' (meaning no disrespect) animals. This is passing on a problem that someone is afraid to deal with and actually damages conservation efforts. Spaces in captivity should be properly utilised and not filled with non contributing members of a species. Such slots may be filled for 20, 30 or more years.

The link about the new 'menagerie' at Wolverhampton left me wondering. It states "The animals have come from zoos, breeders, animal sanctuaries". Interesting. Which zoos sent which animals? Another case of dumping surplus stock?

Houston Zoo...$50 million!!!!!! Wow! That is going to be worth seeing.

I note that Dai Nam has got into a bit of trouble. Too many tigers. I visited once but the zoo section was not yet open. If I can scrape a few pennies together I may go again in a couple of weeks.

The story about Jodie Marsh and the cheetah annoyed me on two counts. Firstly you don't purchase a cheetah to "start a breeding programme". Two cheetahs do not a programme make. There are already two EEP's for cheetah. Having to actually purchase an animal suggests that the one already held is not in either of these established programmes and neither is the one being bought. Do correct me if I am wrong.

My man of the month is Thane Maynard. A special breed. Respect! I would welcome the opportunity to meet the guy. Maybe one day.

On with the links:

Goodbye, Jumbo - The identity crisis of the modern zoo
In zoo parlance, they’re known as charismatic megafauna. We’re talking lions, tigers, and other large creatures. They are the big-ticket beasts and the reason, historically anyway, why people have come to the zoo. Where there is megafauna, the thinking goes, there will be crowds.
That’s partly what made Ron Kagan’s decision so shocking. The executive director of the Detroit Zoo announced in 2004 that he was voluntarily sending his zoo’s two Asian elephants to a California sanctuary, where the land was plentiful, the weather temperate, and the elephants could roam. The reason, Kagan said, was simple. To paraphrase: The zoo, despite its best efforts, was essentially ruining the elephants’ lives.
“It wasn’t like an elephant died or something like that,” Kagan said recently. “There was just a progression, struggling for years, recognizing there was a problem, and that these were common problems for elephants. We just kept thinking, ‘What can we do?’ ”
Kagan’s choice, which is still reverberating in the zoo industry five years later, marks the latest twist in a long, often clumsy, historical shift - from animals caged for our delight, to a more enlightened conservation message, and finally to the notion that zoos can actually change human behavior by teaching us about the ways we’re damaging the natural world. Now more than ever, zoos are bringing the message of wildlife conservation to the forefront, making it not only part of their marketing plans, but their core missions. Indeed, some zoo directors now say conservation is the only pure reason for keeping animals at all.
Yet within this noble notion there is a fundamental and nagging problem: Zoos, despite their evolution, remain a form of entertainment, with the animals unwittingly playing the main roles. So if zoo directors are trying more than ever to do right by the beasts in their care, providing them in many cases with hyper-naturalistic, state-of-the-art exhibits and greater attention to what the animals might actually want, then it seems only a matter of time before they ask themselves some tough questions: Should they be keeping animals at all? If so, which ones, and why? Should elephants be in zoos? Should gorillas?
“If you asked somebody in our profession 10 years ago, ‘Is the gorilla happy?’, they would get really upset and say, ‘Why would you ask such an anthropomorphic question?’ ” said Kagan, 57. “But these sort of things now are legitimately a part of scientific study and assessment.”
Consequently, many, including Kagan, see changes on the horizon. Nigel Rothfels, the author of “Savages and Beasts: The Birth of the Modern Zoo” (Johns Hopkins, 2008) believes zoos of the future will have fewer species and larger spaces for them to occupy. Those that choose to keep elephants and other large species, he argues, will likely do it better than ever before, putting significant resources into the projects. But most zoos, Rothfels believes, will make a different choice: they will give up the charismatic megafauna that people have come to expect. In other words, the biggest challenge for some zoos in the years ahead may be letting go“There may well be fewer zoos in the future,” Rothfels said recently. “But the zoos that will be there will be better.”
It makes for both an exciting and challenging time in zoos. Despite their critics, the institutions remain very popular. As the recent debate over Zoo New England’s troubled parks has revealed, people love their zoos. Even as government funding dries up, attendance at many zoos is steady, and even rising. And with the natural world in increasing peril - poachers killing elephants in Africa, climate change threatening habitats worldwide, and American children increasingly sealed off into safe suburban bubbles - many zoo officials feel that this is their moment, their chance to remind people why wildlife matters, before it is too late.
“We need to make that connection, and it’s not hard,” said Bill Conway, the legendary former director of the Bronx Zoo and now a senior conservationist at the Wildlife Conservation Society. “It’s very different to see an animal live, to make that emotional connection, to look it in the eye and have it look back at you.”
People have been collecting exotic animals for centuries. Babylonian royals, Chinese rulers, and Egyptian kings all dabbled in it, keeping at times alligators, bears, lions, and elephants in private collections. The purpose was often sheer entertainment. At animal parks in early China, fights are said to have been staged, sometimes between man and beast. Later, Europeans used animal preserves for hunting, and finally, in the 1700 and 1800s, modern zoos, with animals on display for public viewing, began to emerge in European cities.
In 1874, the first zoo in the United States opened to great fanfare in Philadelphia. With a brass band playing and flags fluttering, thousands of people arrived that morning and queued up to see the exotic wallabies, kangaroos, bears, and an Indian elephant.
In the 75 years or so that followed, others rushed to top Philadelphia’s early offerings, as American zookeepers engaged in something akin to animal “stamp collecting,” Conway said. The goal, generally speaking, was to acquire as many species as possible and house them, often alone, in simple cages. “One of this, one of that, one of the next thing,” said Steve Feldman, spokesman for the Association of Zoos and Aquariums. “Just so you could see what a tiger looked like.”
But in 1979, Kiki, the gorilla, stepped into a different world. Held captive for years amid concrete and bars at the Woodland Park Zoo in Seattle, he was given a lush new exhibit, designed by his caretakers to resemble the wild African home where he had lived so briefly. There was grass and a stream, and then this shift: Not only did zoo officials believe the gorillas loved it, so did the visitorsA new push for hyper-naturalism began to consume zoos across the country while conservation efforts, practiced by some zoos for years, also began to take center stage. In 1980, the Cincinnati Zoo founded its Cat Ambassador Program to help raise awareness about the troubles facing cheetahs in Africa. Two years later, the San Diego Zoo pioneered conservation work that helped to bring the California condor back from the brink of extinction, and throughout the 1980s and ’90s, many zoos continued along these twin paths: raising awareness about the plight of animals while often housing them in environs that looked, if not felt, more true-to-life.
But some zoos stumbled upon a paradox: As much as people might care about the animals, they still wanted to be entertained. In 1995, the Kansas City Zoo opened a $32 million, 95-acre Africa exhibit, hoping it would help increase attendance by 50 percent within a year. But it didn’t happen. In an effort to make the sprawling exhibit feel natural, planners neglected to build many places where people could sit and cool down in the summer heat. People had to walk too far to see the animals. And the animals themselves were too hard to see.
“The issues just compounded,” said Randy Wisthoff, the zoo’s current executive director, who took the job in 2003.
Attendance declined, and a 2002 report commissioned by the local Friends of the Zoo told officials what they already knew: The zoo lacked “entertainment value.” What it needed was more safari rides, movie nights, and misting stations. And there was this conclusion, which cuts to the heart of the zoo’s modern-day dilemma. While visitors appreciated that animals might enjoy their nicer habitats, what zoo-goers really wanted was what they have always wanted: animals, up close, and ideally, doing something interesting.
“On the one hand, zoos want to be about conservation and education,” said Jeffrey Hyson, assistant history professor at Saint Joseph’s University and the author of a forthcoming book on zoos. “On the other hand, they’ve got to emotionally appeal to visitors and make things more fun. They’ve got to have birthday parties for the animals, naming contests. They’ve got to turn animals into personalities.”
In a recent study conducted by the Association of Zoos and Aquariums titled “Why Zoos & Aquariums Matter,” researchers surveyed more than 5,000 visitors and reported that zoos are indeed helping to shape the way people think about the natural world. Fifty-seven percent said their zoo visits strengthened their connection with nature. Fifty-four percent said zoos and aquariums prompted them to reconsider their role in environmental problems, and 61 percent talked about what they had learned.
But visitors don’t come to zoos “to eat their vitamins,” said Thane Maynard, executive director of the Cincinnati Zoo & Botanical Garden. And so, zoos are trying to take on an ever more idealistic mission, while serving up fun by blurring the lines between the worlds of the humans and the animals.Chances to feed giraffes or lorikeets are popping up from Little Rock to Albuquerque, and stingray touch tanks are all the rage. Two years ago in Cincinnati, zoo officials built a show around an idea they weren’t even sure would work: a cheetah run. But work it did. Five days a week, before awe-struck crowds, the zoo’s cheetahs now reach speeds up to 40 miles an hour - a little over half their potential - chasing a dog toy on a pulley. The zoo now plans to invest $4 million in a more elaborate cheetah course while other new exhibits, like “Russia’s Grizzly Coast” at the Minnesota Zoo, are not only naturalistic, but bring the animals up close through clever tactics like heated rocks and well-placed pools of water.
“The bears spend a lot of the day - especially in the summer when it’s hot - in the water, swimming, playing with each other, and sometimes trying, and succeeding, to catch live fish,” said Lee Ehmke, director and CEO of the Minnesota Zoo, where the exhibit opened last year. “It’s awesome. People stay for an hour sometimes.”
The power of these close encounters, Ehmke said, is that people are being compelled to care. There is nothing, zoo officials argue, like being face-to-face with an animal. That makes people appreciate the beauty of nature, Ehmke said. As a result of its new exhibit, Minnesota zoo officials raised $15,000 last year that went directly to field conservation work, and they are not alone. According to the Association of Zoos and Aquariums, accredited zoos raise roughly $70 million a year for conservation projects.
That fund-raising does not justify caging animals in the eyes of some animal rights activists. These critics argue that zoos would have a far greater impact if they spent their money solely on keeping animals free, not captive. And in Detroit, at least one zoo official believes that zoos should be focusing more on something else.
Ron Kagan isn’t against conservation; that’s part of the mission, he said. What he’d like to see more of, however, is in-depth discussion about animal welfare, how to best gauge it, and what to do about it if zoos are falling short of meeting animals’ needs. It’s a discussion that may lead to the conclusion that the zoos’ ultimate mission means giving up more of its animals, but Kagan’s all right with that.
He recently traveled to San Andreas, Calif., 120 miles east of San Francisco, and visited the sprawling sanctuary where he sent his two elephants in 2005. One of them, Winky, died last year, euthanized at age 56. But the other, named Wanda, is doing well, Kagan said. There in the grassy foothills of the Sierra Nevada Mountains, she is living out her days on a 100-acre patch of land that, to him, anyway, seems pretty much like paradise.

PETA opposes saving zoo
Dear Ms. Young and Commissioners:I'm writing on behalf of PETA regarding the The Zoo of Northwest Florida's pleas for public funding and to urge you to continue denying such requests. Not only is the zoo financially unstable, it also appears to have engaged in a contract that could transfer animals at the zoo to a private owner. An article in the December 18, 2008, edition of the Pensacola News Journal (enclosed) indicates that the zoo received a $100,000 "loan" from Marcella Leone, owner of a private menagerie in Stamford, Conn. The enclosed documents from the Florida Secured Transaction Registry, filed on December 30, 2008, seem to indicate that the zoo's animals were used as "collateral" for the loan (the documents specifically mention the zoo's baby orangutan, Indah). PETA has asked the U.S. Fish and Wildlife Service to investigate whether this transaction may constitute buying, selling, or otherwise engaging in commercial acts in violation of the Endangered Species Act. Leone's facility is not accredited by the Association of Zoos and Aquariums and is also not recognized as a sanctuary. All too often, animals at such facilities are passed on to exotic-animal breeders or dealers, private collections, pseudo-sanctuaries, shabby roadside zoos, the pet trade

Cincinnati Zoo's cheetah looks to set new land speed record for mammals
The Cincinnati Zoo announced this week that one of its resident cheetahs, an 8-year-old female named Sarah, will participate in an attempt to set a new land speed record for mammals. Sarah will vie for the record with another 8-year-old female cheetah named Nkosazana (which means "Princess" in Xhosa, one of South Africa's official languages) from a South African organization called Cheetah Outreach.The two cheetahs won't face off in a head-to-head race; instead, each will make three timed 100-meter dashes on an enclosed course in her home country. Nkosazana (or Zaza for short) will run first; her attempt at record-breaking will be held Aug. 15. A little less than a month later, on Sept. 9, Sarah will travel to the Kentucky Speedway near Sparta, Ky., where Cincinnati Zoo staff hope she'll be able to beat the time set by Zaza. The record-breaking attempts aren't just for fun, zoo officials said -- they're intended to raise awareness about the plight of

A new study has found, though, that the outrageously big structure helps to keep the bird cool in the heat of the tropical day.The beak of the toco toucan – the largest member of the toucan family – accounts for about one-third of the bird's body length, which is larger than the beak of any other bird for its size.

Donkey Business - The only zebra in Gaza
Something didn't quite look right about the zebra, but it was hard to say exactly what. Of the several ramshackle zoos in Gaza, Marah, located not far from the Bureij refugee camp, is by far the cheeriest: The animals are lively, the enclosures clean, and children gather around the cage of a resting lion.Then again, the competition is hardly stiff: The zoo in Rafah features dead animals left to rot in their cages; another animal park, situated in a densely populated neighborhood in Bureij, recently shut down amid financial difficulties (and after neighbors complained of the smell). A third, also in Bureij, is so short of funds that a fox is kept in a grocery cart with a board over the top.Yet Marah, with its broken-down bumper cars and a pit filled with sadly deflated balls, had its own not-quite-right feel—particularly the zebra. Standing near the back of its cage, facing away from the spectators, the animal kept its head tucked down."It's really a painted donkey," admitted Mahmud Berghat, the director of Marah, when asked about the creature.

Biologists Rediscover Endangered Frog Population
Zoo, Museum, State and Federal Agencies Collaborate To Save Mountain Yellow-Legged FrogFor the first time in nearly 50 years, a population of a nearly extinct frog has been rediscovered in the San Bernardino National Forest’s San Jacinto Wilderness. Biologists from the U.S. Geological Survey (USGS) assessing suitability of sites to re-establish frogs and scientists from the San Diego Natural History Museum retracing a 1908 natural history expedition both rediscovered the rare mountain yellow-legged frog in the San Jacinto Wilderness near Idyllwild, Calif.This re-discovery — along with the San Diego Zoo’s first successful breeding of the frog in captivity, and successful efforts by California Department of Fish and Game to restore frog habitat — renews hope of survival for this Southern California amphibian.Globally, amphibians are on the decline because of habitat loss, effects of climate change and the spread of a deadly pathogen called the chytrid fungus. The mountain yellow-legged frog is one of three frogs or toads on the federal Endangered Species List in Southern California. Prior to this recent discovery, USGS researchers

Tortoise plan would involve 1,000 acres
The latest Nye County desert tortoise habitat conservation plan would be a high-impact plan allowing the disturbance of up to 1,000 acres over 10 years, planner Kyle Walton told county commissioners Tuesday afternoon.Previous plans were termed low effect, covering up to 100 acres. A low-effect plan would mean it would be an insignificant impact to the environment and would fly under the radar when it came to having to comply with requirements of the National Environmental Policy Act."Up to 100 acres, we could probably justify. It is going to be the responsibility of the Fish and Wildlife Service to justify to the public that this is, in effect, a low-effect habitat conservation plan. The higher impact, the greater the number of acres that can be disturbed, the harder it is for us to make the case to the public that this is indeed a low-effect plan," said U.S. Fish and Wildlife Service Biologist Jeri Krueger.Nye County planner Kyle Walton, who gave

Worshippers cry foul as Madhya Pradesh ‘de-fangs’ Nagpanchmi
Nagpanchmi, the festival of snakes, which was celebrated Sunday, left many Hindu worshippers disappointed when they went to temples but found no snakes. The forest department had taken snake charmers to task for displaying the reptiles. Nagpanchami is a festival of snakes celebrated on the fifth day of the bright fortnight in the Hindu holy month of Shravan. People visit temples of Hindu god Shiva, worship snakes and offer them milk besides alms to the snake charmer who brings them. But now, there are no snake charmers seen in the towns and cities as the forest department has warned them of strict action if they bring the reptiles on Nagpanchmi. In the absence of snake charmers, many people have crafted images of snakes using cow dung on either side of the entrance of their houses to welcome the snake god. “We have been worshipping snakes on this day for ages but now our right to worship is being encroached upon by the government,” said B.L. Mehra who lives in the posh Kanchan Nagar locality of Bhopal. Hindu mythology is full of stories and fables about snakes, the most important

Zoo celebrates breeding success
A Cornish zoo has helped an endangered species of mammal by successfully breeding two rare Owston's Civets.The cubs are part of a breeding programme at Newquay Zoo, which also supports a conservation programme in the civets native home of Vietnam. Three years ago the zoo bred the first twins to be born outside South East Asia. A total of five cubs have been bred by the zoo - three of which have been transferred to other zoos in the UK. Owston's Civets are at risk from the illegal wildlife trade and trapping for their fur and meat. Stewart Muir, director of Newquay Zoo, said

VIN SUPRYNOWICZ: Save the habitat, kill the turtles
When -- in the name of heaven, I demand to know -- are those responsible for enforcing the Endangered Species Act going to do something about remediating the habitat devastation and starting to recover the minuscule remaining population, before it has dwindled past the point of no return, of that brave and noble beast, the poodle?What? Are you serious, Vin? There are, like, 68 million domestic pet dogs in this country, and the poodle is the seventh most numerous breed. There are millions of poodles out there.As a matter of fact, purebred poodles are among the 4 million to 6 million dogs euthanized in America each year because homes can't be found for them. America's dog and cat problem is not species extinction; it's overpopulation.Well, to anyone tempted to respond in that manner, let me clarify for you what the Endangered Species Act is really all about. You see, the number of poodles living in domestic captivity doesn't count. Once we have succeeded in getting the noble poodle listed as threatened or endangered -- as it most certainly is, in the traditional range of its wild habitat -- all that will matter is the number of wild, untouched acres set aside. Once you've developed a house and a yard and put two happy poodles in it, for purposes of the federal ESA, you might as well have just shot the pups, because you have destroyed wild poodle habitat, and we are going to count your poodles as "taken," meaning dead. In fact, we may have to take steps to stop you from allowing them to breed, up to and including "euthanizing" your captive slave dogs, since "Unlimited breeding of an endangered species in captivity is something the community has to look into." You think I'm making this up? Here in Las Vegas, Clark County's Desert Conservation Program -- a well-paid division of the county Department of Air Quality and Environmental Management -- is currently going hat in hand to the appropriate chain of federal agencies, asking "permission" to amend the so-called Desert Tortoise (and 77 other critters, including bugs and mosses) Habitat Plan, with the purpose of "allowing" the county to develop an additional 215,000 acres of adjoining stinking desert ....

‘More to zoo than feeding, cleaning animals’
Laura Tardieu has loved animals since she was a child, so it came as no surprise when she chose to work at a zoo. Tardieu is employed at Emperor Valley Zoo, where she has assumed the position of temporary zoologist since February. Dressed unpretentiously in a pair of track pants, polo shirt and sneakers, Tardieu looked quite relaxed while seated in the lobby of the Zoological Society’s office on the zoo’s compound during a recent interview. The 28-year-old shared her experiences at several foreign zoos and the changes she hoped to implement in the diets of the animals here at home.Her inspirationWhen she was ten, Tardieu said she was inspired by a documentary and knew at that point exactly what she wanted to do. “My dream was inspired by a film. There was a zoologist who was protecting elephants whose tusks were being hunted, and I felt strongly about that, and I said to myself ‘I wanna do what he is doing.’ That was

A hippo critical situation
HACIENDA Napoles was Pablo Escobar's pleasure palace, a 5,500-acre estate where the notorious drug lord reigned over million-dollar cocaine deals, parties with underage girls and visits by shadowy men of power.Escobar lived large here in his lush fiefdom 100 miles east of Medellin, far from the teeming slums where he began his life of crime. He built a bullring, an airstrip, an ersatz Jurassic Park with half a dozen immense concrete dinosaurs. He stocked a private wild animal park with hundreds of animals, including elephants, camels, giraffes, ostriches and zebras. He installed four hippos in one of the estate's 12 man-made lakes.Today, Hacienda Napoles is in ruins, taken over by jungle foliage and bats. The sprawling Spanish-style mansion has been gutted, scavenged by treasure hunters looking for stashes of gold and cash buried under the floors. Escobar is long gone, cut down in a hail of police gunfire.But the hippos are still here.More than 15 years after the government took control of Hacienda Napoles, the elephants, giraffes and zebras have long since disappeared, given away to Colombian zoos or left to die.But the hippos were never claimed because they were too large and ornery to move. Now the original four have multiplied to 16 and, far from starving to death, as some expected, they have learned to forage like cows. In fact, local authorities say they represent a safety hazard — and are standing in the way of plans to redevelop the late drug lord's estate.At night, several of them emerge from their watery habitats and roam for miles looking for grass to munch on. Three months ago, a male hippo was shot to death by ranchers after he wandered three miles from the rest of the herd to a neighboring stream.Weighing up to 3 tons, the hippos are not constrained by ordinary barbed-wire fences or gates."The problem is, you cannot manage them," said Francisco Sanchez, environmental officer of Puerto Triunfo municipality, which has control of the mansion

Hope of freedom for orang-utans dashed - 248 endangered primates left in cages after mining company pulls out of rescue
A world-renowned programme to return hundreds of orang-utans threatened with extinction to the wild has been thrown into disarray by the withdrawal of Britain's biggest mining company from Borneo.Dozens of orang-utans that had been due to be released this month have been left locked in cages after BHP-Billiton warned it could no longer guarantee the safety of the animals on forests it had been surveying for coal. With BHP's support over the past two years, orang-utans from a rehabilitation centre – made famous by the BBC TV series Orang-utan Diary – have been released onto BHP's land in Kalimantan. But last month the world's largest mining company told investors it was withdrawing from the area for "strategic reasons" which it declined to explain. A planned airlift of 48 adult orang-utans scheduled to take place on 20 July was cancelled a week before it had been due to take place. Lone Dröscher-Nielsen, the former air stewardess who cares for 650 orang-utans at the Nyaru Menteng Orang-utan Rehabilitation Centre, said BHP had warned that the Indonesian government was likely to hand its coal concessions to other companies who would not match its environmental stewardship of the land. She added that it now seemed unlikely the Anglo-Australia mining giant would fund a plan to a create a 250,000-hectare wildlife reserve in central Borneo that could have sited 1,000 orang-utans, a genetically

Animal adventure as £1m menagerie opens
A £1 million menagerie of monkeys, meerkats and micro pigs has been created in Wolverhampton.After running an exotic pet shop for more than a decade, brothers Jimmy and Ben Wicks have sunk their life savings into creating Wickid Animal Adventure in Dunstall.The brothers from Wednesfield have spent the past year – and £500,000 each – transforming a patch of wasteland at the side of their shop in Gorsebrook Road into the animal park, which also has wallabies, genettes, skunks and birds of prey.The menagerie also has an exotic pet shop licence and will officially open to the public at 10.30am on Sunday, with admission costing £1.50. The site includes enclosures, a refreshment area and the brothers are working on a nocturnal animal house and pirate-themed aquarium.Jimmy, aged 39, has run Wickid Pets for 11 years and takes care of the wildlife, while Ben, 41, works on the enclosures and models. Father-of-two Ben said: “We bought the shop off the old landlord last May and have sunk absolutely everything into this. “The land was a complete dump at first and we have been working around the clock to bring it up to scratch.“Jimmy has been running the shop for years and is very respected in the field of exotic animals. I think he has always had a project like this in mind, ever since he was five years old and first went to Chester Zoo. There is nothing he doesn’t know about animals.”The animals have come from zoos, breeders, animal sanctuaries and Jimmy’s contacts from the pet shop world. There

Houston Zoo starting work on $50 million African Forest
Moving away from the concept of bars and cages, the Houston Zoo in September will break ground for a $50 million African Forest, a 6.5-acre exhibit designed to give patrons the illusion they are strolling through an open landscape populated with chimpanzees, giraffes and other equatorial animals, zoo officials said Tuesday. Directors of Houston Zoo Inc., the nonprofit organization that manages the zoo, approved Phase 1 of the project Monday, said CEO and President Deborah Cannon. The exhibit is scheduled to open in December 2010. Plans ultimately call for expanding the exhibit to 13 acres, she said.Cannon said the zoo has raised 95 percent of the money needed for the first phase through foundations and other private sources. It will launch its first public campaign for funds to cover the remaining 5 percent.Jim Brighton, a landscape architect with Seattle-based PJA Architects, the project's designer, said the exhibit will tell stories about the African forest, not simply provide an opportunity to look at wild animals in captivity.“Traditional zoo exhibits concentrate on animals, what they eat, how big they are and so forth,” Brighton said

Improper upkeep at Binh Duong wild animal farms
Three private breeding farms for wild animals in the southern province of Binh Duong have failed to meet required technical and safety standards, inspectors have found. The registration certificates of these farms had also expired, provincial inspectors said after carrying out checks on Dai Nam Zoo Co. Ltd., Thai Binh Duong Beer Company and Thanh Canh Enterprise.The three companies, which run zoos and collect entrance fees from the public to view the animals, have a total of 53 tigers, making the province the country’s leading locality in breeding the endangered species.Inspectors found Dai Nam Zoo Co. Ltd. raising 13 tigers although they had registered for seven.In total, the company was found raising 583 wild animals belonging to 71 species although its [expired] registration permits just 294 animals of 27 species.Dai Nam had designed the cages properly for the different species and had veterinarians to take care of them. However, the company did not record its breeding and raising methods or the measures being taken to ensure stable reproduction of the animals under captive conditions.The same violations were also found at the Thai Binh Duong Beer Company that had registered to raise 721 wild animals of eight species. Inspectors found the company was raising two unregistered wild animals but it was not clear which species they belonged to.Tigers at this farm had given birth to 15 young ones but 11 of them died due to in-breeding, the inspectors found.The farm should reinforce its cages to ensure absolute safety for humans as it is located among residential areas, inspectors said.They also found that the Thanh Canh Enterprise was raising nine tigers without informing concerned agencies regularly about their health. They also found that the bars on cages were not close enough to ensure human safety.One tigress at Thanh Canh’s farm had given birth to a young that died soon after, inspectors said, adding none of the companies had declared clearly their purpose for breeding wild animals.Tran Van Nguyen, deputy head of Binh Duong park rangers, said the agency had suggested to higher authorities that the registration is extended for the three companies.He also said the companies would not be allowed to raise the animals for commercial purposes, noting that Vietnam has signed the Convention on International Trade in Endangered Species (CITES) in 1994 and joined the International Tiger Coalition.An official from the inspection team said they had requested the Ministry of Agriculture and Rural Development to instruct the park rangers to tag the tigers with microchips for better management.“I wonder why the Forest Protection Department has not attached microchips on the tigers,” he said. “Without this, the breeder can secretly trade the animal after concealing their reproduction.”On July 16, two men were arrested while transporting a dead tiger from a central province to Hanoi.Hoang Van Su and taxi driver Nguyen Trung Phong were found with a 60-kilogram frozen tiger and 11 kilograms of tiger bones in the trunk of the latter’s cab.Police said Su had hired Phong to carry the tiger and bones from the central province of Thanh Hoa to a buyer in Hanoi.Dr. Pham Trong Anh, an expert from the Hanoi-based Institute of Ecology and Biological Resources, said the tiger was a baby of about 4-5 months. He said the bones belonged to at least two different tigers.It was unclear what the tigers had died of and whether they were wild or taken from illegal farms.In Vietnam, tigers are only found along the Truong Son Mountain Range in the central region. Experts estimate the country has less than 200 tigers left, as most have been wiped out to make traditional medicine.Tiger bones are believed to have aphrodisiac properties by many countries in the Far East and Southeast Asia.Too riskyEarly this month, the World Bank told a key international meeting on wildlife trade that experimenting with tiger farming is too risky and could drive wild tigers further toward extinction.“Extinction is irreversible, so prudence and precaution suggest that the risks of legalized farming are too great a gamble for the world to take,” World Bank Director Keshav Varma told the member countries of the 58th meeting of the Convention on International Trade in Endangered Species (CITES) Standing Committee on July 9.Because of the unpredictability of the market environment and the small number of remaining tigers in the wild, there is “no room for experimentation,” Varma, who leads the World Bank’s Global Tiger Initiative, said after the meeting.“Commercial trading in tiger parts and its derivatives is not in the interest of wild tiger conservation.”“Given the unpredictability of the market environment along with the fact that there are only 3,500 tigers in the wild, there is no room for experimentation,” Varma told the International Tiger Coalition (ITC).The World Wide Fund for Nature (WWF) later endorsed the World Bank’s call for countries to ban tiger farming because of the uncertainty that it will have for the long-term conservation of wild tigers.“Stopping all trade in tiger parts, and phasing out these tiger farms, is of the utmost urgency if the tiger is to survive in the wild,” said Dr. Susan Lieberman, director of the species program at WWF International.“It is time for the world community to join together, with tiger range state governments, to stop all poaching of tigers for illegal trade, and WWF welcomes the engagement of the World Bank in these efforts,” she said.

Orangutans employ unique strategies to control branch flexibility
Orangutans are the largest habitually arboreal mammal. For them, as for all arboreal mammals, access to the abundant fruits and narrowest gaps found among the thin peripheral branches of tree crowns poses considerable safety risks and energetic demands. Most arboreal primates use flexed-limb postures to minimize problems caused by branch compliance and instability. Here, we show that Sumatran orangutans employ unique locomotor strategies to control compliance and allow access to the terminal branch niche for feeding and gap crossing. We calculated a “stiffness score,” which is a measure of the flexibility of the supports on which orangutans moved. We found that certain locomotor behaviors clearly are associated with the most compliant supports; these behaviors appear to lack regular limb sequences, which serves to avoid the risk of resonance in branch sway caused by high-frequency, patterned gait. Balance and increased stability are achieved through long contact times between multiple limbs and supports and a combination of pronograde (horizontal) and orthograde (vertical) body postures, used both above branches and in suspension underneath them. Overall, adult females seem to be

Jodie Marsh helps zoo find female partner for cheetah
A ZOO is trying to raise thousands of pounds to find a female partner for its cheetah. Around 1,000 people came along to a fundraising event at Eagle Heights, supported by glamour model Jodie Marsh, to watch two-year-old Boumani run a five-second sprint to catch his dinner. A target total of €9,000 (£7,800) is needed to buy a female cheetah from Germany to start a breeding programme, but so far the zoo has only managed to raise £1,000. The fundraiser at the zoo in Lullingstone Lane, Eynsford, also featured treasure hunts, bird and reptile displays, and a tortoise race. Zoo director Alan Ames says Boumani is the only cheetah in the UK to run in front of the public.

The zoo dilemma
THE fate of the world's 1,000 or so remaining zoos offers a barometer of changing social mores on wildlife. From the ancient practice of maintaining menageries of exotic animals for the entertainment of royal courts, the modern zoo was instituted by Sir Stamford Raffles (in an interesting local historical context) to bring animals to where people live. Nowadays, wildlife enthusiasts prefer going where the animals live. Raffles, an inveterate naturalist who gave his name to the Rafflesia flower now prominent in our tourism branding, set up the Royal Zoological Gardens in London in 1828, giving the word "zoo" to the world. Zoo Negara, established in 1963, was originally faithful to Raffles' idea of displaying wild flora and fauna for the edification of urban societies. In the four decades since, however, there have been fundamental changes in popular attitudes towards wildlife. Zoos have kept apace with these changing values by expanding into animal research and husbandry, shifting their role from cabinets of curiosities into centres for the study and protection of wildlife. Their very ethos has changed: what used to be called zoos have become "wildlife conservation centres", "bioparks" or "safari parks"; cages and concrete enclosures have given way to more open and free-ranging exhibits, where visitors might see captive animals in less obviously distressing habitats.But even this is not halting the decline in popular interest in and support of zoos. Where zoos used to boost attendance with performing parrots or elephant rides, these are now considered abusive of animals. Caught between declining interest and rising costs, Zoo Negara's present existential conundrum clearly needs a wider solution than its owner-operator, the Malaysian Zoological Society, can muster as a non-governmental organisation. Two questions need to be addressed: Is Zoo Negara worth keeping? And, if so, will there be sufficient political will for the government to step in with the money, more systematically than in the occasional matching-funds disbursements of the zoo's early years?Approaching its first half-century, Zoo Negara is now hemmed in by urban development. Proposals for relocation have sundered on the "not-in-my-backyard" syndrome as well as over the disposition of the zoo's 48ha of land, now far more valuable than ever anticipated in 1963. With mounting concerns over the welfare of its more than 5,000 specimens of nearly 500 species, the zoo's dedication to preserving endangered species would be tragically ironic if it is unable to maintain its own existence.

Conserving Big Cats Works: Proof Published from South African Leopard Field Study
The Munyawana Leopard Research Project at &Beyond Phinda Private Game Reserve in KwaZulu-Natal began in April 2002 and has been instrumental in the long-term conservation of local leopard populations. Guided by Dr. Luke Hunter and Guy Balme from Panthera, the research is the most comprehensive study on leopards ever conducted, specifically in terms of the length of study, the number of leopards collared and the outputs generated from the research. Since inception, 64 leopards have been collared (the highest recorded in previous studies was 31), over 13000 locations logged and more than 1600 direct leopard observations made.

Estonia to send three rare Amur leopards to US, Britain
Three extremely rare Amur leopard cubs that were born at Estonia's Tallinn zoo last spring will have new homes in US and British zoos, the Estonian institution said."The birth of all three cubs was an extraordinary event because there are only 50 Amur leopards still living in the wild," Mati Kaal, director of Tallinn Zoo, told AFP."All live in Amur, in an area surrounded by Russia, China and North Korea," he said. "During the last century, the number of Amur leopards has decreased dramatically due to human carelessness."Edgar, the largest cub, will make his new home at Erie Zoo in the US state of Pennsylvania, while another male, Toomas, and a female cub, Kaia, will go to Marwell Zoo in the county of Hampshire, southern England."We are not asking for any money, but the receiving zoo has to pay the costs of transport," Kaal said."Zoos across the globe cooperate very well and exchanging

Sharifs' burning tiger gets frosty reception in boiling Pakistan
Biting sarcasm tears into political family's plan to keep imported Siberian cat in chilled pen as Pakistanis roast amid power cutsWhen a Siberian tiger landed in the Pakistani city of Lahore last week, at the height of a sweltering summer, some worried that the blistering temperatures might prove too much for the rare animal.But in the end the heat proved too much for its owners, the politically dominant Sharif family, who, after a round of lacerating media criticism, have offered to give the hapless tiger up.The animal was flown in from Canada by Suleiman Sharif, a nephew of the opposition leader, Nawaz Sharif, who is known as the "Lion of Punjab". The Pakistani government banned the import of big cats last February.However, Sharif junior has got powerful connections: his father, Shahbaz, is chief minister of Punjab. So when the tiger landed at Lahore airport, it was welcomed by the chief minister's private secretary, who whisked it through customs.According to press reports, Suleiman planned to house the tiger in a chilled enclosure at the family's private zoo on the Raiwind estate, on the outskirts of the city. A second tiger had been ordered from Canada.The matter, when it hit the newspapers, prompted outrage, not so much because it highlighted the powerful dodging the law, which is nothing unusual in Pakistan, but due to the insensitivity of building a refrigerated room at a time when most Pakistanis are labouring under extensive electricity outages in roasting weather."It is hard to see the inhabitants of Siberia faring well in the heat and humidity of Lahore," noted an acerbic editorial in The News, which demanded an official investigation. Its competitor, Dawn, queried: "Wouldn't millions of Pakistanis … be outraged?"And so the tiger had to go. Today, the World Wildlife Fund office said the Sharif family had offered to donate the politically problematic animal to charity. "They contacted our office to say they are ready to hand over the animal. It's in their interest to give it up," said the charity's director for Pakistan, Ali Hassan Habib. "And so it should be. We want to use this opportunity to educate them."Habib said he would try to place the tiger with a suitable zoo in Lahore, otherwise the animal woul

VIP allowed to import Siberian tigers in violation of ban
The government has issued a permit to Suleman Shahbaz Sharif, son of Punjab Chief Minister Shahbaz Sharif, to import a pair of Siberian tigers, a rare and highly endangered species, in violation of a ban.According to sources, the federal environment ministry issued the permit in the first week of June to Suleman Sharif for the Sharif Wildlife Breeding Farm, Jati Umra, Raiwind Road.International transport of endangered species is controlled and monitored by the Convention on International Trade in Endangered Species of Fauna and Flora (CITES) whose secretariat is in Geneva. Its focal point in Pakistan is the Islamabad-based National Council for Conservation of Wildlife (NCCW). The sources said that a ban on import of tigers, lions and other big cats by the private sector imposed by the NCCW had been breached within four months.One of the tigers — a male — arrived at the Allama Iqbal International Airport in Lahore a couple of days ago from Toronto by PIA’s flight PK-790. The CITES permit No. P04/2009 was issued on June 4 and the same day the NCCW also issued a permit, No. F7– 6/78 NCW.Suleman Sharif had declared the value of the rare tiger — purchased from Norm Philip, Northwood Zoo and Animal Sanctuary, 2192 Cookson Lane, Sea Grave, Ontario, Canada — as $5,000. He spent $7,829 on air fare, etc. Customs duty and other taxes of Rs109,458 were paid by Sikander Pasha who had come to get the carnivorous beast of the endangered species cleared on behalf of Suleman Sharif who had reportedly got stuck in a traffic jam on way to the airport.A document of the NCCW says that the two permits were issued to the Lahore Zoo (for two white tigers) and Suleman Sharif (for two white tigers — one male and one female). The sources said the decision to ban import of big cats had been taken at a meeting presided over by Federal Environment Minister Hameedullah Jan Afridi on Feb 13 this year. At the meeting, the Director General of the Worldwide Fund for Nature (WWF), Ali Hassan Habib, who is a member of the NCCW, referred to obligations under international conventions and said there was no need to allow import of big cats. He said that some people were indulging in illegal trade under the garb of operating zoos. NCCW’s wildlife conservator Umeed Khalid said a committee had been constituted at the council’s previous meeting to approach the WWF for drafting viable standards and legislation for import of big cats and keeping them in captivity. The Inspector General for Forests, Dr Iqbal Sial, — a retired BPS-20 official who had been hired on a contract and was holding the charge of the BPS-21 post — said import of big cats had been stopped until the legislation. According to the minutes of the meeting, ‘the ban on the import of big cats for the private sector will continue until legislation/standards are in place.’This reporter approached NCCW conservator Umeed Khalid and IGF Iqbal Sial several times over the past four weeks, and Mr Khalid said he was waiting for his boss’s permission to give information and Dr Sial termed the information ‘confidential’.Responding to this reporter’s queries at the Karachi Press Club on July 10, the environment minister had ordered IGF Iqbal Sial to provide the information to the media. Mr Afridi also called the IGF the following day in Islamabad and asked

Baby elephants spark fighting in Sri Lanka
Two baby elephants under five years old were taken away from their mothers, sparking anger in a world-renown elephant orphanage in central Sri Lanka, a local English newspaper said on Monday. The Island said the two baby tuskers were forcibly separated from their mothers by the Diyawadana Nilame Pradeep Nilanga Dela, the chief custodian of the Temple of the Tooth, on Saturday night at the Pinnawala Elephant Orphanage, about 80 km northeast of the capital Colombo. Despite protests by some officials at the elephant orphanage, after hours of battle, the Diyawadana Nilame who was supported by nearly 50 persons including police and Army personnel finally managed to take the two elephants to the central town of Kandy. `I consider it as one of darkest hours in my career as an employee at Pinnawala to witness the struggle between the two mothers who were heavily chained, when their babies were taken away. We boast our cultural and religious values but we continue to be inhuman when it comes to dealing with animals,` a spokesman from the elephant orphanage was quoted by the paper as saying. Officials at the elephant orphanage said that it was not customary to separate baby elephants who depend on their mother`s milk. `If it is to be separated from its mother, the elephant has to be over five years old,` one official was quoted by the paper as saying. Officials from the Department of National Zoological Gardens said one of the

Dublin Zoo Elephant Facility Design Workshop
Thursday October 15th 2009 – Sunday October 18th 2009

When designing the Kaziranga Forest Trail at Dublin Zoo we asked the following questions:

How do Asian Elephants live in the wild and what do elephants need to really be elephants?

The inspiration for the entire design process came from nature and a deep respect for the animals concerned.

The design process was undertaken with open minds and we carefully listened to the very best people in the field of elephant care. The Dublin Zoo team is very proud about the end result, yet accept that we have not stopped learning about the complex needs of elephants. We are looking forward to sharing our experiences with you and sincerely hope that you will find it valuable.
