Abstract: A seminoma and parathyroid adenoma were diagnosed in an aged snow leopard. The ultrastructural appearance of the seminoma was similar to that described in the dog and in man. The lack of significant amounts of rough endoplasmic reticulum, Golgi complexes and free ribosomes in the parathyroid adenoma suggested that it was non-functional. Parathyroid adenoma has not been previously described in a large wild feline.

Abstract: Dissections were made of the larynges of 14 species of the cat family, with representative specimens from all genera. It was found that the vocal folds of the larynx of genus Panthera (with the exception of the snow leopard) form the basic structure of a sound generator well- designed to produce a high acoustical energy. Combined with an efficient sound radiator (vocal tract) that can be adjusted in length, a Panthera can use its vocal instrument literally to blow its own horn with a 'roar'. Also, it is proposed that laryngeal morphology can be used as an anatomical character in mammalian taxonomy.

Abstract: Two adult snow leopards (Panthera uncia), male and female, both with vaccinations current, became infected with feline panleukopenia virus (FPV) at the Blank Park Zoo, Des Moines, Iowa, in late 1988. Clinical signs included weakness, hemorrhagic feces, fever, seizures, and nasal discharge. Blood analysis revealed severe lymphopenia and mild anemia. A positive enzyme-linked immunosorbent assay (ELISA) test for FPV on fecal contents from the male leopard confirmed the diagnosis. In spite of intensive therapy, both animals died. Necropsy of the female, which survived for 1 wk after onset of signs, revealed intestinal crypt necrosis, pulmonary consolidation, necrotizing laryngitis, and diffuse lymphoid depletion. The male leopard, which lived 3 wk after onset of illness, had similar enteric and lymphoid lesions. In addition, there was a severe interstitial pneumonia, with syncytial cells containing eosinophilic intracytoplasmic inclusion bodies. Ultrastructural characteristics of these inclusions featured tubular structures consistent with a paramyxovirus. Although repeated virus isolation attempts from the affected lung were negative, polyclonal and monoclonal fluorescent antibody tests were strongly positive for canine distemper virus (CDV). Frozen paired sera from each leopard demonstrated very high acute and convalescing titers to FPV; both animals also seroconverted to CDV, with titers in the male leopard higher than those in the female. Additional tests for toxoplasmosis, feline infectious peritonitis, feline rhinotracheitis, feline calicivirus, feline leukemia, canine parainfluenza, and bovine respiratory syncytial virus were all negative. The neurologic signs present in these leopards remained unexplained, but may have been attributable to CDV infection. A feral cat trapped on zoo property had feces positive for FPV by ELISA. Although the specific contributions of FPV and CDV toward the development of this case are unknown, it is likely that initial FPV-induced immunosuppression allowed the subsequent development of CDV in these snow leopards. The likelihood that initial FPV infection came from feral cats underscores the importance of feral animal control on zoo premises.

Abstract: Fauna of the mammals in Dzungarian Ala Tau included 54 species, from them in IUCN Red book, the Red Data book of USSR and Kazakh Red Data Book listed snow leopard, dhole, brown bear, Central Asian otter, Turkestan lynx, manul, argali, marbled polecat and stone marten. Institute of geography of Kazakhstan offers the project on creation of protected territory on Dzungarian Ala Tau for biodiversity conservation and increase in number of rare and disappearing species.

Abstract: 50 mammal species permanently live in the nature reserve. There penetrate snow leopard, wolf, corsac, and wild boar on a relatively regular basis. Moral, roe deer, and elk migrate outside the Markakol depression in winter. Though mentioned in literature as species inhabiting the nature reserve, beaver, stone marten, and dhole are not met there today.

Abstract: The data on predators and ungulates population dynamics in Almaty Nature reserve (Kazakhstan) in 1983-1987s are given. The number of snow leopard is stable (3-5 individuals), the density is 0.06 indi/1000 ha. An insignificant increase of Siberian ibex' number (660 to 700) with density of 36 indi/1000 ha is recorded.

Abstract: There is one subspecies U.u.uncia in Kazakhstan. It is distributed in the Tien Shan, Djungar Ala-Tau, Tarbagatai, Saur, South Altai, and preys mainly on ibex, roe deer, argali, and marmots. Its litter consists of one to five cubs (normally two three). Female bears once in two years.

Abstract: Habitat, status of population, geographical distribution, number, and ecology of snow leopard in Tien Shan are analyzed based on original realistic material collected 1981 through 1988.Information about irbis in the `foreign' part of its habitat is given for comparison. The reasons for snow leopard habitat shrinkage in Central Asia and Kazakhstan for over 100 years are assessed. Status of ungulate populations snow leopard prey on is given. The predator's behavioral pattern and condition in enclosure are given consideration. Protection measures are proposed.
