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: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
