| Abstract | The snow leopard (Panthera uncia Schreber, 1776) population in Russia and Mongolia is situated at the northern edge of the range, where instability of ecological conditions and of prey availability may serve as prerequisites for demographic instability and, consequently, for reducing the genetic diversity. Moreover, this northern area of the species distribution is connected with the western and central parts by only a few small fragments of potential habitats in the Tian-Shan spurs in China and Kazakhstan. Given this structure of the range, the restriction of gene flow between the northern and other regions of snow leopard distribution can be expected. Under these conditions, data on population genetics would be extremely important for assessment of genetic diversity, population structure and gene flow both at regional and large-scale level. To investigate large-scale and fine-grain population structure and levels of genetic diversity we analyzed 108 snow leopards identified from noninvasively collected scat samples from Russia and Mongolia (the northern part of the range) as well as from Kyrgyzstan and Tajikistan (the western part of the range) using panel of eight polymorphic microsatellites. We found low to moderate levels of genetic diversity in the studied populations. Among local habitats, the highest heterozygosity and allelic richness were recorded in Kyrgyzstan (He = 0.66 ± 0.03, Ho = 0.70 ± 0.04, Ar = 3.17) whereas the lowest diversity was found in a periphery subpopulation in Buryatia Republic of Russia (He = 0.41 ± 0.12, Ho = 0.29 ± 0.05, Ar = 2.33). In general, snow leopards from the western range exhibit greater genetic diversity (He = 0.68 ± 0.04, Ho = 0.66 ± 0.03, Ar = 4.95) compared to those from the northern range (He = 0.60 ± 0.06, Ho = 0.49 ± 0.02, Ar = 4.45). In addition, we have identified signs of fragmentation in the northern habitat, which have led to significant genetic divergence between subpopulations in Russia. Multiple analyses of genetic structure support considerable genetic differentiation between the northern and western range parts, which may testify to subspecies subdivision of snow leopards from these regions. The observed patterns of genetic structure are evidence for delineation of several management units within the studied populations, requiring individual approaches for conservation initiatives, particularly related to translocation events. The causes for the revealed patterns of genetic structure and levels of genetic diversity are discussed. | ||||

| Title | Fast, flexible alternatives to regular grid designs for spatial capture–recapture. | Type | Research Article | ||

| 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. |

| Abstract | The Snow Leopard (Uncia uncia) was a very rare species in China. The survey on the markings of Snow Leopard in Ahay and Tianshan Mountains is the major activity of the Project of Snow Leopard in Xinjiang, supported by International Snow Leopard Trust(ISLT)and Xinjiang Conservation Fund(XCF). During the field work from Sep to Nov 2004 the Xinjiang Snow Leopard Group(XSLG) set 67 transects of a total length of 47 776 m with mean transect length is 7 1 3 m at 9 locations.Total of 1 l 8 markings of Snow Leopards were found in 27 transects the mean density is 247km. The markings of Snow Leopard included the pug marks or footprints, scrapes, feces, bloodstain, scent spray, urine, hair or fur, claw rake, remains of prey corpse, sleep site, roar and others. From the quantity and locations of marks the XSLG got the information on habitat selection distribution region and relative abundance of the Snow Leopard in the study areas. The survey also provided knowledge on distribution and abundance of major prey potential conservation problems and human attitudes to Snow Leopards by taking 200 questionnaires in the study areas. | ||||

| Abstract | In accordance with order of the Ministry of Nature and Tourism, zoologists of our association have made surveys in three ways such as reasons why snow leopards attack domestic animals, “Snow leopard” trial operation to count them and illegal hunting in territories of Khovd, Gobi-Altai, Bayankhongor, Uvurkhangai and Umnugobi provinces from September 2009 to January 2010. As result of these surveys it has made the following conclusions in the followings: Reason to hunt them illegally: the principal reason is that administrative units have been increased and territories of administrative units have been diminished. There have been four provinces in 1924 to 1926, 18 since 1965, 21 since 1990. Such situation limits movements of herdsmen completely and pastures digressed much than ever before. As result of such situation, 70% of pastures become desert. Such digression caused not only heads of animals and also number of species. Guarantee is that birds such as owls, cuckoo, willow grouse in banks of Uyert river, Burkhanbuudai mountain, located in Biger soum, Gobi-Altai province, which are not hunted by hunters, are disappearing in the recent two decades. For that reason we consider it is urgently necessary for the government to convert administrative unit structures into four provinces. This would influence herdsmen moving across hundreds km and pastures could depart from digression. Second reason: cooperative movement won. The issues related to management and strengthening of national cooperatives, considered by Central Committee of Mongolian People's Revolutionary Party in the meeting in March 1953 was the start of cooperatives' movement. Consideration by Yu. Tsedenbal, chairman of Ministers Council, chairman of the MPRP, on report “Result of to unify popular units and some important issues to maintain entity management of agricultural cooperatives” in the fourth meeting by the Central Committee of Mongolian People's Revolutionary Party /MPRP/ on December 16-17, 1959, proclaimed complete victory of cooperative. At the end of 1959, it could unify 767 small cooperative into 389 ones, unify 99.3 % of herdsmen and socialize 73.3 % of animals. The remaining of animals amount 6 million 163 thousands animals, and equals to 26.7% of total animals. This concerned number of animals related to the article mentioned that every family should have not more that 50 animals in Khangai zone and not more 75 animals in Gobi desert. It shows that such number could not satisfy needs of family if such number is divided into five main animals in separating with reproduction animals and adult animals. So herdsmen started hunt hoofed animals secretly and illegally in order to satisfy their meat needs. Those animals included main food of snow leopard such as ibex, wild sheep, and marmot. Third reason is that the state used to hunt ibex, which are main nutrition of snow leopards, every year. The administrative unit of the soum pursued policy to hunt ibex in order to provide meat needs of secondary schools and hospitals. That's why this affected decrease of ibex population. Preciously from 1986 to 1990 the permissions to hunt one thousands of wild sheep and two thousands of ibexes were hunt for domestic alimentary use every year. Not less than 10 local hunters of every soum used to take part in big game of ibexes. Also they hunted many ibexes, chose 3-10 best ibexes and hid them in the mountains for their consummation during hunting. Fourth reason: hunting of wolves. Until 1990 the state used to give prizes to hunter, who killed a wolf in any seasons of the year. Firstly it offered a sheep for the wolf hunter and later it gave 25 tugrugs /15 USD/. Every year, wolf hunting was organized several times especially picking wolf-cubs influenced spread and population of wolves. So snow leopard came to the places where wolves survived before and attack domestic animals. Such situation continued until 1990. Now population of ibexes has decreased than before 1990 since the state stopped hunting wolves, population of wolves increased in mountainous zones. We didn't consider it had been right since it was natural event. However population of ibexes decreased. Fifth reason: Global warming. In recent five years it has had a drought and natural disaster from excessive snow in the places where it has never had such natural disasters before. But Mongolia has 40 million heads of domestic animals it has never increased like such quantity in its history before. We consider it is not incorrect that decrease of domestic animals could give opportunities to raise population of wild animals. Our next survey is to make attempt to fix heads of snow leopards correctly with low costs. |

| Abstract | The Snow Leopard (Uncia uncia) investigation in the Tomur area is the second step of the “Project of Snow Leopard Study in Xinjiang”. In this part of the project, we collected information on the distribution , abundance and population size of the snow leopard in this area. The investigation lasted for 3 weeks, between October 17 and November 7th, 2004. During the 22 days of field work, we surveyed 4 different places in Wensu County, Aksu District: e.g. Pochenzi and the Muzat River area, Bozdun and the Little Kuzbay River area, Yinyar and the Tomur River area, Taglak and the Qiong Tailan River area. The 4 main areas, along with a few other valleys, covered most of the Tomur National Conservation Zone. In total, we ran 42 transects. In 15 transects, we found signs left by snow leopards. We also collected 15 fecal samples for diet analysis. This time we interviewed nearly 90 local people from different nationalities: e.g. Han (Chinese), Uygur and Kyrgyz people, including herdsmen, geologists, mineworkers, drivers, veterinarians, businessmen, forest officials, soldiers and policemen. They provided us with an array of information on the historical and current distribution and abundance of the snow leopard in this area. | ||||
