Abstract: In Russia, traditions of track observations and the use of tracking techniques in studying the ecology and behavior of mammals were founded by A.N. Formozov. An analytic review of his data on large carnivorous mammals (tiger, snow leopard, wolf, brown bear, wolverine, and others) is given. A special detailed observation of animals' tracks as a source of information on their life is shown only to start. The efficiency of track observations in various fields of studies, including counting animals, is estimated. The values of day and night distances for various animal species, given in literature, have never been properly substantiated methodically. The tracking method is the most effective in studying the use of the home range by animals, drawing the network of their movements and scent-marking behavior. The hunting behavior of large predators in dense forests is can only be deduced by observing their tracks. In some cases, the use of tracking has a distinct advantage over radio tracking. The main propositions are illustrated by the materials of the author obtained in various Russian regions (in forests of the northern Russian Plain and southern Far east) for 1958-1998.

Abstract: In 1998, under the WWF Altai-Sayans ecoregion conservation program, traces of snow leopard were detected in the ridges of Tsaran-Shibetu and Shipshal. The density of vital activity traces is comparable with those in northern Mongolia.

Abstract: A high percentage of rare species in Central Asia experience limited conditions for distribution. Geographic centers with higher species diversity are generally constrained in terms of territory: they are formed when ranges overlap. But in Central Asia and along its borders with Russia, centers of biodiversity overlap at the very marginal edges of ranges. Central Asian species cross into Russian territory, where desert and steppe are replaced by thick forest. Here the northern borders of their ranges are sharply fragmented and isolated. Typical examples for Central Asia are the ranges of the cheetah (Acinonyx jubatus), Asian leopard (Panthera pardus caucasica), striped hyena (Hyaena hyaena), Bukhara deer (Census elaphus bactrianus), markhor (Capra falconeri), blue sheep (Pseudois nayauf) and argali (Ovis ammon). In Russia are the Altai subspecies of argali, the Siberian argali (O.a.ammon), the mountain goat (Capra sibirica), Mongolian gazelle (Procapra gutturosa), snow leopard (Uncia uncia), Pallas' cat (Felis manul), dhole (Cuon alpinus), grey marmot (Marmota baibacina), Mongolian marmot (M. sibirica) and tolai hare (Lepus tolai). Where the numbers o f individuals has fallen to extreme lows, the most effective mechanism for species survival may be supporting the integrity of ranges, in order to preserve population exchanges between neighboring groups. The geographic location of reserves and other protected territories is vitally important for the survival of Central Asian species, given the acute fragmentation of their ranges. These reserves should include significant, viable centers of population the key places. Wherever the creation of permanent protected territories is impossible, a new tactic must be found, such as introducing temporary limitations on the use of land for agriculture and hunting. But all protected territories, whether temporary or permanent, should be connected, forming a core and periphery. The marginal range areas must not be forgotten, if total protection of endangered populations is to be accomplished.

Abstract: A full hierarchic system of mammal fauna in the USSR and CIS countries, list of synonyms, comments on taxonomy, and information about geographical distribution are given. Genus Uncia Gray, 1854 includes one species U. uncia (Schreber, 1776) distributed in highlands (up to 5,000 m) of Central Asia (Tibet, Pamir, Tien-Shan, Altai). Synonyms: irbis.

Abstract: There is adducing information about number and modern condition of C.ferox, G.barbatus, A.chrisa‰tus, M.menzbieri, U.arctosisabellinus, L.lutra seistanica, H.hiena, F.lynx isabellina, U.uncia, C.elaphus bactrianus, G.subgutturoza, C.falconeri, O. ammon severtzovi, O. orientalis bochariensis and other species during last years in Chatkal, Nuratau, Hissar, Surkhan and Kyzylkum nature reserves. There is prognosis in changing of number.
