Koshkarev E. (2000). What has happened to the snow leopard after the break-up of Soviet Union? (Vol. 4 (19)).
Abstract: It describes status of snow leopard in republics of the former Soviet Union, main reasons for poaching and negative and positive experience on species conservation. The total number of snow leopard in Kyrgyzstan and Tajikistan in the 1980's was at least 1200-1400. In Kazakhstan the snow leopard population totaled 180-200, in Uzbekistan around 100, and in Russia 150-200. The number and natural habitat of the species were in universal decline. Losses in Kyrgyzstan from poaching alone were no less than 30 animals per year in 1960-1980's. During this period the population in this area decreased by half, and the natural habitat by one third. With the break-up of the Soviet Union, poaching of the snow leopard and its pray grew by at least a factor of 3-4. It was estimated that 500-600 animals reduced the Kyrgyz snow leopard population in the 1990's. The population that remains today can barely be more than 150-200 individual snow leopards. The population has been physically decimated. Number of snow leopard in existence today in the former Soviet Union does not exceed 700-900 individual animals.

Abstract: Papillomaviruses (PVs) are highly species- and site-specific pathogens of stratified squamous epithelium. Although PV infections in the various Felidae are rarely reported, we identified productive infections in six cat species. PV-induced proliferative skin or mucous membrane lesions were confirmed by immunohistochemical screening for papillomavirus-specific capsid antigens. Seven monoclonal antibodies, each of which reacts with an immunodominant antigenic determinant of the bovine papillomavirus L1 gene product, revealed that feline PV capsid epitopes were conserved to various degrees. This battery of monoclonal antibodies established differential expression patterns among cutaneous and oral PVs of snow leopards and domestic cats, suggesting that they represent distinct viruses. Clinically, the lesions in all species and anatomic sites were locally extensive and frequently multiple. Histologically, the areas of epidermal hyperplasia were flat with a similarity to benign tumors induced by cutaneotropic, carcinogenic PVs in immunosuppressed human patients. Limited restriction endonuclease analyses of viral genomic DNA confirmed the variability among three viral genomes recovered from available frozen tissue. Because most previous PV isolates have been species specific, these studies suggest that at least eight different cat papillomaviruses infect the oral cavity (tentative designations: Asian lion, Panthera leo, P1PV; snow leopard, Panthera uncia, PuPV-1; bobcat, Felis rufus, FrPV; Florida panther, Felis concolor, FcPV; clouded leopard, Neofelis nebulosa, NnPV; and domestic cat, Felis domesticus, FdPV-2) or skin (domestic cat, F. domesticus, FdPV-1; and snow leopard, P. uncia, PuPV-2).

Abstract: Describes the drastic decline of the dwarf blue sheep since the 1950's primarily due to over-hunting. There are an estimated 200 individuals remaining in a 295 square km range in Batang county, China. The authors recommend urgent protection for this species.

Abstract: A canine beta-casein cDNA was isolated from mammary tissue by polymerase chain reaction (PCR) using degenerate primers. It encodes 250 amino acids protein containing the conserved sequence motif of beta- casein. It showed the highest homology with snow-leopard (Uncia uncia (55-62% identity). It also showed 44-53% identity with human, 33-42%, identity with mouse, 29-37%, identity with rat, 43-53% identity with rabbit, 41-48% identity with pig, 44-51% identity with cattle and 44- 50% identity with sheep. A 1.2-kb mRNA was detected in mammary tissue by Northern blot analysis. Phylogenetic analysis revealed that canine beta-casein formed a branch with lesser panda and snow leopard, which were grouped into carnivore.
