Abstract: Most conventional spermatology research involves common mammalian species including livestock, laboratory animals and humans. Yet, there are more than 4500 mammalian species inhabiting the planet for which little is known about basic reproductive biology, including sperm characteristics and function. This information is important, not just as adjunct knowledge, but because the majority of these species are threatened with extinction, largely due to human-induced pressures. The field of conservation is changing rapidly, and global cooperation is emerging among a variety of wildlife enthusiasts, ranging from management authorities of nature reserves to curators of rare zoological collections. Conservation progress depends on systematic, multidisciplinary research first to answer basic questions, with new data then applied to endangered species management plans. The reproductive physiologist is a crucial component of this scheme. Reproduction is the essence of species survival, and enormous effort needs to be directed at these 'untraditional' research species, subspecies and populations. Spermatology research combined with simultaneous efforts in endocrinology, embryology and cryopreservation (among others) can lead to the successful application of assisted reproduction. Examples from this laboratory include an array of wild felid species and a rare cervid and mustelid. Obstacles to success are formidable, including unique species-specificities, diminished genetic diversity and a general lack of resources. Nonetheless, the field offers tremendous opportunities for generating unique knowledge of comparative interest and with conservation utility.

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: The Disappearance of traditional ungulate prey of the snow leopard may be contributing to its endangered status in the wild. Soviet biologists have noted that wild sheep are a primary prey of the snow leopard in the southern Russian union republic and the Central Asian union republic of the U.S.S.R. While poaching appears to have had some impact on the status of these sheep, econmic pressures may be contributing to their decrease. Evidence presented for KAzakhstan and three regions of the Russian republic demonstrates that commercial sheep and goat production appears to be growing at a very high pace in these areas, thus consumming habitat otherwise available for wild herds.
