Abstract: The annual reproductive cycle of the male snow leopard (Panthera uncia) was characterized by evaluating seminal and endocrine traits monthly. Testicular volume was greatest (P < 0.05) during the winter months when the quality of ejaculate was optimal. Ejaculate volume, total sperm concentration ml-1, motile sperm concentration per ejaculate, sperm morphology and sperm motility index were lowest during the summer and autumn months compared with the winter and spring. Peripheral LH, FSH and testosterone concentrations were also lowest during the summer months, increasing during the autumn just before the increase in semen quality, and were maximal during the winter months. There was a direct relationship (P < 0.01) between: (1) testosterone and testicular volume, total sperm concentration ml-1, motile sperm concentration per ejaculate and ejaculate volume, and (2) LH and testicular volume and motile sperm concentration per ejaculate. In summary, although spermatozoa were recovered throughout the year, optimal gamete quality was observed during the winter and spring. Although previous studies in felids have demonstrated seasonal effects on either seminal or endocrine traits, this is the first study to demonstrate a distinct effect of season on both pituitary and testicular function.

Abstract: Of the many problems facing the republics of Central Asia and Kazakhstan after the break-up of the USSR, poaching of endandered animals is of particular concern. Everything is up for sale through the black market, networks of acquaintances, middlemen or even advertisements in the newspapers: horns, skins, mounted trophies, animal parts for traditional medicine. Interest in snow leopard and Turkestan lynx (Lynx lynx isabellinus Blyth), and skins and horns from mountain sheep and goats sharply increased in 1992-93, and prices grew unusually high.
