Abstract: Irrigation and drainage activity in Tien Shan led some bird species to disappear. Number of species to build their nests in tree holes has dropped. Mongolian sandpiper and black-bellied sand grouse disappeared in the steppe areas. Great bustard, formerly nesting in this area, can now be rarely seen only in migration. The direct anthropogenic influence resulted in shrinkage of game animal and bird populations such as moral, goitered gazelle, argali, snow leopard, and stone marten.

Abstract: Given is data concerning disease (sarcoptosis) of Siberian ibex (Capra sibirica) in Western Tien Shan. The carriers of the disease are adult males of Capra sibirica during distant migrations that as a rule take place in anticipation of snowy winters or owing to human influence. Ibexes are not merely infected with sarcoptosis but perish enmasse from the disease. In the first year the disease strikes down, in the main, migrants – adult males. Predators including snow leopard kill the weakened animals. During the recent five years the density of Carpa sibirica at the Chatkal Mountain-Forest Reservation dropped 2.3-fold as a result of sarcoptosis and owing to the migrations caused by the reduction of the population. Is recommended: 1. Stringent veterinary control at places of possible contacts between infected domestic animals and healthy wild ungulates. 2. Using modern technology migration routes of ungulates should be studied for elaborating effective measures of quarantine.

Abstract: Three key areas of the snow leopard habitat in the USSR are geographically segregated: Central Asia (Pamir, Tien Shan, Pamiro-Alai), East Kazakhstan (Jungar Alatau, Tarbagatai, Saur), and South Siberia (Altai, the Sayans), which are separated from one another. The fate of snow leopard in East Kazakhstan and South Siberia causes the most anxiety.

Abstract: Collected are additional data on encounters with six rare animal species that have been never seen before in the West Tien Shan. These are free-toiled bat, Etruscan shrew, snow leopard, little forktail, urban swallow, Central Asia tortoise, and Kyrgyz racerunner.

Abstract: Zoolites of the Felidae family are known from the Upper Eocene Lower Pliocene in Eurasia, Africa, and North America. Two sub-families are know to inhabit the territory of the USSR and adjacent territories: the extinct sabre-toothed Felidae species Machairodontia and now existing Felidae species. In the USSR the extinct Felidae species were found to exist in Upper Miocene, Upper and Middle Pliocene, and Pleistocene. In Eurasia panthers has been know since early Pliocene. Three species were found in Uzbekistan – the extinct cave lion Felidae sd†l…†… (Goldfuss, 1810), and now existing P…nth†a… tigris, P…nth†a… pardus. The ancient finds and modern habitats are briefly described. Genus Uncia is represented by one species snow leopard or irbis. Probably it appeared in later Pliocene or Pleistocene in the mountain of Central Asia. In Uzbekistan, remains of snow leopard were found in the Samarqand region in the layer of Upper Pleistocene or Holocene. Probably it moved into the area in Pleistocene or the period of glacier removal in the Western Tien Shan mountains, Turkestan, Zeravshan, and Hissar ridges.
