Jumaev T. (1989). Fauna. Nature protection in mountains and nature reserves.
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.

Yakhontov A.A. (1950). Fauna of mountains.
Abstract: Ibex, whose population has reduced due to over-hunting, inhabits the alpine meadow zone in Uzbekistan. Ibex had entirely disappeared in some areas. Wild sheep, a common inhabitant of the alpine zone, has drastically decreased in number. Marhur can still be found in the mountains of Kugitang and Babatang. Wild sheep is a common species for the alpine zone. Predator animals such as snow leopard, bear, and sometimes wolf and fox can be found in this zone. A typical inhabitant of highlands is marmot an object of fur-trade.

Formozov A.N. (1987). Fauna of mountainous areas in Kazakhstan.
Abstract: The author provides description of fauna of Kazakhstan's mountainous areas. Fauna of the mountain taiga is also typical for the forests of South Siberia. Ungulate species such as musk deer and ibex are common for rocky taiga areas. In the Altai, ibex, musk deer, and wild sheep are preyed on by dhole and snow leopard and more typical species such as glutton and wolf. Ibex, argali, and irbis are typical for Transili Ala-Tau and West Tien Shan. Tien Shan is the only area of the USSR with quite many irbis preserved. The ridges of this mountainous area located in Kazakhstan are very likely to be an area the most densely populated by snow leopards within the predator's habitat.

Alibekov L.A. (1978). Fauna.
Abstract: Represented is fauna of big salt-marsh valleys and pre-Kyzylkum area, a tier of low desert foothill valleys, tiers of lowland ridges, deeply cut hillside midlands, and cold highlands of the watershed ridge-top tier in the Jizak region of Uzbekistan. The highest tier of the Jizak region, a habitat of snow leopard, Menzbier's marmot, Siberian ibex, sometimes wild Tajik sheep coming from the East, bear ascending from lower elevations, and wolf in summer, has the most adverse living conditions. Central Asia argali and stone marten inhabit in central part of the North Nurata ridge.

Artykbaev P.K. (1981). Fauna.
Abstract: Uzbekistan's fauna includes 97 mammal species (insectivorous six species, Cheiroptera 20, hare type species 2, rodents 37, ungulates 8); 379 bird species, of which 184 are passerine; 58 reptile species; 69 fish species. Species inhabiting sand deserts, clay deserts, and mountains are listed. The following mammal species inhabit the alpine zone: bear, snow leopard, ermine, weasel, wolf, Siberian mountain ibex, wild sheep, Menzbier's marmot and long-tailed marmot, voles, red pica. The following game species are listed in the Red Book: bear, leopard, lynx, snow leopard, cheetah, caracal, otter, marbled polecat, goitered gazelle, Bukhara deer, marchor, and wild sheep (there are two wild sheep sub-species in the country Bukhara and Kizilkum wild sheep).

Berg L.S. (1938). Fauna.
Abstract: It provides description of fauna of the Central Asia mountains. Ibex (Capra sibirica) was noticed to keep to the alpine and sub-alpine zone and never descends bellow 2,500 m. Hunting for ibex and wild sheep, snow leopard (Leopardus uncia) keeps at the same elevation.

Durbach, I., Borchers, D., Sutherland, C., Sharma, K. (2020). Fast, flexible alternatives to regular grid designs for spatial
capture–recapture..
Abstract: Spatial capture–recapture (SCR) methods use the location of
detectors (camera traps, hair snares and live-capture traps) and the locations at which animals were detected (their spatial capture histories) to estimate animal density. Despite the often large expense and effort involved in placing detectors in a landscape, there has been relatively little work on how detectors should be located. A natural criterion is to place traps so as to maximize the precision of density estimators, but the lack of a closed-form expression for precision has made optimizing this criterion computationally demanding. 2. Recent results by Efford and Boulanger (2019) show that precision can be well approximated by a function of the expected number of detected individuals and expected number of recapture events, both of which can be evaluated at low computational cost. We use these results to develop a method for obtaining survey designs that optimize this approximate precision for SCR studies using count or binary proximity detectors, or multi-catch traps. 3. We show how the basic design protocol can be extended to incorporate spatially varying distributions of activity centres and animal detectability. We illustrate our approach by simulating from a camera trap study of snow leopards in Mongolia and comparing estimates from our designs to those generated by regular or optimized grid designs. Optimizing detector placement increased the number of detected individuals and recaptures, but this did not always lead to more precise density estimators due to less precise estimation of the effective sampling area. In most cases, the precision of density estimators was comparable to that obtained with grid designs, with improvement in some scenarios where approximate CV(¬D) < 20% and density varied spatially. 4. Designs generated using our approach are transparent and statistically grounded. They can be produced for survey regions of any shape, adapt to known information about animal density and detectability, and are potentially easier and less costly to implement. We recommend their use as good, flexible candidate designs for SCR surveys when reasonable knowledge of model parameters exists. We provide software for researchers to construct their own designs, in the form of updates to design functions in the r package oSCR. |
