Abstract: Modern felid species descend from relatively recent (<11 million years ago) divergence and
speciation events that produced successful predatory carnivores worldwide but that have
confounded taxonomic classifications. A highly resolved molecular phylogeny with divergence dates
for all living cat species, derived from autosomal, X-linked, Y-linked, and mitochondrial gene
segments (22,789 base pairs) and 16 fossil calibrations define eight principal lineages produced
through at least 10 intercontinental migrations facilitated by sea-level fluctuations. A ghost lineage
analysis indicates that available felid fossils underestimate (i.e., unrepresented basal branch
length) first occurrence by an average of 76%, revealing a low representation of felid lineages
in paleontological remains. The phylogenetic performance of distinct gene classes showed that
Y-chromosome segments are appreciably more informative than mitochondrial DNA, X-linked,
or autosomal genes in resolving the rapid Felidae species radiation.

Abstract: Melengestrol acetate (MGA) is the most widely used contraceptive in zoo felids, but the mechanism of contraception and the pathologic effects have not been investigated. For this study, the effects of MGA on folliculogenesis were assessed, and the association of MGA with ovarian lesions was evaluated. Comparisons were made among the histopathologic findings in the ovaries from 88 captive wild felids (representing 15 species) divided into three groups: 37 currently contracepted with MGA, eight previously exposed to MGA, and 43 never contracepted. Ninety-one percent of the felids evaluated had tertiary follicles, and no differences were noted between contracepted and uncontracepted cats. Some MGA-contracepted cats also had corpora lutea indicating recent ovulation. These results indicate that folliculogenesis is not suppressed by current doses of MGA and ovulation occurred in some cats. Therefore, the contraceptive actions of MGA do not occur by suppressing folliculogenesis, and MGA-contracepted felids likely have endogenous estrogens that may confound progestin effects on the uterus. Cystic rete ovarii was the most common pathologic finding, but they were not more prevalent in MGA-contracepted cats. These findings indicate that MGA is not associated with ovarian disease, including ovarian cancer, in contrast to the uterine lesions noted in MGA-treated cats.

Abstract: It describes history of the Chatkal and Aksu Jabagly nature reserves' establishment and provides data concerning hydrography, soils, climate, landscapes, altitude zoning, flora and fauna, and main aspects of scientific work.

Abstract: It describes natural conditions, area, flora and fauna of the three mountain nature reserves in Uzbekistan: Chatkal, Kyzylsu, and Miraki. Siberian mountain ibex, roe deer, wild boar, Turkistan lynx, Tien Shan brown bear, fox, stone marten, Menzbier's marmot, porcupine, ermine, and Tien Shan souslik inhabit the Chatkal nature reserve. Snow leopard can be found in a top rocky part of the ridge. In the Kyzylsu nature reserve, there are 23 mammal species including, among the others, white-clawed bear, snow leopard, Iranian otter, Turkistan lynx, wild-boar, badger, porcupine, long-tailed marmot, hare-tolai, stone marten, Pamiri shrew, and ibex; in the Miraki nature reserve snow leopard, white-clawed bear, ibex, wolf, fox, porcupine, long-tailed marmot, hare-talai, forest dormouse, red pica, and a number of Red Data Book bird species are protected.

Abstract: Being one of nine nature reserves in Uzbekistan, Chatkal was established in 1947. Its area changed its size and administrative jurisdiction. Foothills adjacent to the nature reserve were long ago inhabited and developed by people. In Middle Ages, the area of juniperous forest reduced considerably because of mining operations. There are rare mammal species in the nature reserve, such as snow leopard, bear, Menzbier's marmot, and six rare bird species

Abstract: Study on the current status of large mammals species population was carried out in Khunjerab National Park, Northern Areas. The observation recorded showed that the population of Tibetan Red fox (Vulpes vulpes montana), Snow leopard (Uncia uncia), and Wolf (Canis lupus) have, though a bit, increased but are still in the rank of “Endangered”. While the population of Himalyan Ibex (Cpara ibex sibirica) is increasing more rapidly and their status is now “Common” in the Park. The limited population of Marcopolo sheep (Ovis ammon polii), Tibetan wild Ass (Equus hemionus kiang) and Brown bear (Urus arctos) is still under threat, and comes them under “Critical Endangered” category.

Abstract: Last years scientists from Zoology institute have analyzed the modern status of vertebrates of Uzbekistan and trend of the populations. As a result 63 vertebrates including 22 mammals including snow leopard were recommended to be include into preparing Red Data book of Uzbekistan as endangered species. Unfortunately many of specialists' recommendations connected with establishing new protected areas are not putting into practice.

Abstract: From March to May, 2006œªwe conducted extensive snow leopard surveys in the Burhanbuda Mountain Kunlun Mountains, Qinghai Province, China. 32 linear transect of 5~15 km each, which running through each vegetation type, were surveyed within the study area. A total of 72 traces of snow leopard were found along 4 transects (12.5% of total transects). The traces included pug marks or footprints, scrapes and urine marks. We estimated the average density of wild ungulates in the region was 2.88ñ0.35 individuals km-2(n=29). We emplaced 16 auto2 trigger cameras in different environments and eight photos of snow leopard were shot by four cameras and the capture rate of snow leopard was 71.4%. The minimum snow leopard population size in the Burhanbuda Mountain was two, because two snow leopards were phototrapped by different cameras at almost same time. Simultaneously, the cameras also shot 63 photos of other wild animals, including five photos are unidentified wild animals, and 20 photos of livestock. We evaluated the human attitudes towards snow leopard by interviewing with 27 Tibetan householders of 30 householders live in the study area. We propose to establish a nature reserve for protecting and managing snow leopards in the region. Snow leopard (Uncia uncia) is considered as a unique species because it lives above the snow line, it is endemic to alpines in Central Asia, inhabiting in 12 countries across Central Asia (Fox, 1992). Snow leopard ranges in alpine areas in Qinghai, Xinjiang, Inner Mongolia, Tibet, Gansu and Sichuan in western China (Liao, 1985, 1986; Zhou, 1987; Ma et al., 2002; Jiang & Xu, 2006). The total population and habitat of snow leopards in China are estimated to be 2,000~2,500 individuals and 1,824,316 km2, only 5% of which is under the protection of nature reserves. The cat's current range is fragmented (Zou & Zheng, 2003). Due to strong human persecutions, populations of snow leopards decreased significantly since the end of the 20th century. Thus, the
snow leopards are under the protection of international and domestic laws. From March to May, 2006, we conducted two field surveys in Zhiyu Village, Dulan County in Burhanbuda Mountain, Kunlun Mountains, China to determine the population, distribution and survival status of snow leopards in the area. The aim of the study was to provide ecologic data for snow leopard conservation.

Abstract: A detailed description of the snow leopard habitat in Turkmenistan, Tajikistan, Uzbekistan, Kyrgyzstan, Kazakhstan, Mongolia, China, Pakistan, and India is given. Provided are data concerning its distribution and population size in the USSR, Kazakhstan and other neighbour countries, as well as its habitat, catching, and fur trade. Reduction of the snow leopard catching volumes for zoological trade to 10 or less animals is recommended to preserve the species; establish two new highland nature reserves; improve the management of snow leopard raising in captivity.

Abstract: In a popular form, it tells about rare vertebrate animals included in the Red Data Book of the USSR, their biology, behavioral patterns, threats and measures being taken to protect them. Total number of snow leopard in the USSR is defined as 2,000 animals. 200 snow leopards live in zoos throughout the world. The animals successfully reproduce themselves in the Moscow, Kaunas, and Alma-Ata zoos. Snow leopard's maximum life expectancy in enclosures is 22 years.
