Abstract: It provides general information about the Hissar nature reserve (Uzbekistan), its physico-geographical features and description of flora and fauna. The following predator species inhabit the nature reserve: wolf, fox, Tien Shan brown bear (four five animals per 100 sq. km), ermine, weasel, stone marten, otter, badger, lynx (two animals per 100 sq. km) and snow leopard (about 10 animals). Wild boar and ibex are common species for the area (22 25 animals per 100 sq. km).

Abstract: Among large predators included in the Red Data Book of the USSR and Red List of IUCN the author describes snow leopard. A population of snow leopard in the USSR is estimated to be 500 animals, and no more than 1,000 in the world. In the past, irbis was believed to be a harmful animal and hunting for this species was encouraged. Today, population of the predator is reducing because of poaching and decreasing number of species it preys on such as ibex, wild sheep, wild boar, and marmots. The situation is exacerbated by biological features of this species first of all its slow rate of reproduction. It is concluded that snow leopard needs urgent protection measures since the species is on the verge of disappearance.

Abstract: Uzbekistan's mountain fauna is characterized by the presence of species endemic to Central Asia, and species typical for Mediterranean, India, Afghanistan, the mountains of Central Asia, Mongolia, Siberia, and other neighbouring countries and regions. Of 300 mammals of the USSR, more than 120 inhabit mountains of Central Asia. More diverse is the bird fauna (500 species) and fish fauna. The mountain species are distributed according to the highland zoning. The fauna of highland zone is very peculiar: brown bear, snow leopard, ermine, weasel, wolf, Siberian ibex, argali, and marmot. The following species are under protection in the mountain nature reserves in Uzbekistan: Siberian ibex, roe-deer, Menzbier's marmot, stone marten, ermine, Turkistan lynx, Tien Shan brown bear, Severtsev's sheep, wild boar, marbled polecat, steppe cat, porcupine, snow leopard, otter, badger, long-tailed marmot, marchor, urial, etc. Development of the area resulted in disappearance of Caspian tiger and dhole. The endangered species are cheetah, North Persian leopard, striped hyena, houbara bustard; extremely endangered are Transcaspian urial, marchor, otter, black stock, etc.

Abstract: Patterns of mitochondrial restriction fragment length polymorphism (RFLP) variation were used to resolve more recent relationships among the species of the Felidae ocelot lineage, domestic cat lineage, and pantherine lineage. Twenty-five of 28 restriction enzymes revealed site variation in at least 1 of 21 cat species. The ocelot lineage was resolved into three separate sister taxa groups: Geoffroy's cat (Oncifelis geoffroyi) and kodkod (O. guigna), ocelot (Leopardus pardalis) and margay (L. wiedii), and pampas cat (Lynchailurus colocolo) and most of the tigrina samples (Leopardus tigrina). Within the domestic cat lineage, domestic cat (Felis catus), European wild cat (F. silvestris), and African wild cat (F. libyca) formed a monophyletic trichotomy, which was joined with sand cat (F. margarita) to a common ancestor. Jungle cat (F. chaus) and black-footed cat (F. nigripes) mtDNAs diverged earlier than those of the other domestic cat lineage species and are less closely related. Within the pantherine lineage, phylogenetic analysis identified two distinct groups, uniting lion (P. leo) with leopard (P. pardus) and tiger (P. tigris) with snow leopard (P. uncia).
