First Far Eastern leopard captured in southeast Russia by international team

15.11.2006
World's most endangered big cat is assessed by experts then released

Just three days after catching a Siberian tiger in the Russian Far East, an international team led by biologists from the Wildlife Conservation Society captured another species last week that carries the dubious distinction of being the world's most endangered big cat: an extremely Far Eastern leopard.

One of only 30 left in the wild, the animal was captured in a "trapline" – a series of snares set out by scientists to temporarily catch big cats for genetic analysis. The 45 kg (100 pound) male was captured in Southwest Primorski Krai in the southern Russian Far East less than 20 miles from the Chinese border, and just a mile from where a large male Siberian tiger had been caught days earlier.

Before the leopard was released, a team of scientists from WCS, Institute of Biology and Soils of the Russian Academy of Sciences, and the Laboratory of Genomic Diversity of the National Cancer Institute conducted a suite of medical evaluations including the collection of sperm to asses its capacity to reproduce. Genetic analyses, used in conjunction with other bio-medical evaluations, will be used to determine whether leopards and tigers suffer from the effects of inbreeding by closely related individuals, a common problem in small wildlife populations.

Although more than 400 Siberian tigers occur in the wild, less than 20 tigers in Southwest Primorye are isolated from the main population of Siberian tigers to the east and north, raising questions about their genetic composition and vigor of this subpopulation. With only 30 individuals remaining in the wild, all in Southwest Primorye, the Far Eastern leopard is far more endangered than the tiger, and hence concerns about the genetic status of this animal are even greater. Up to now, no information on these wild animals has been available to assess the risk of disease or inbreeding.

"This capture represents a milestone in our cooperative efforts to save the Far Eastern leopard and Siberian tiger from extinction," said Dale Miquelle, Director of the Wildlife Conservation Society's Russia Program, which has led coordination of this project. "With the information gained from these animals, and others to come, we will be in a much better position to determine appropriate conservation actions."

If inbreeding is considered a serious problem, new genetic material may be introduced into this population, as was done for the Florida panther. In that situation, when poor reproduction and physical abnormalities suggested that inbreeding was the culprit, pumas from Texas were introduced into Florida, resulting in increased reproductive rates and greater vitality of the Florida population. Such actions may be necessary for the Far Eastern leopard, but decisions will be made only after analyses of a representative sample of the remaining population.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
