	Title	Status of wild Bactrian camels and other large ungulates in south-western Mongolia			Type	Journal Article
	Year	1999	Publication	Oryx	Abbreviated Journal
	Volume	33	Issue	3	Pages	247-255
	Keywords	argali; Asian wild ass; Bactrian camels; Camelus bactrianus; goitred gazelle; Mongolia.; 5230
	Abstract	Abstract Wild Bactrian camels Camelus bactrianus ferus are endangered. Surveys over the past several decades suggest a marked decline in camel numbers and reproductive success. However, most surveys were made using methods that precluded rigorous population estimation. The need for more accurate surveys resulted in an aerial survey of known and suspected camel habitat in Mongolia during March 1997. We estimated density, group density and population size of large mammals in south-western Mongolia using the interactive computer program DISTANCE. We recorded sufficient data for population modelling of wild Bactrian camels, goitred gazelles Gazella subgutturosa, Asian wild asses Equus hemionus and argali sheep Ovis ammon. We observed 277 camels in 27 groups (mean group size = 10.269 +- 2.38 SE camels: group). Modelling yielded a population estimate of 198 +- 802 SE camels in the survey area. Population modelling for other ungulates yielded estimates of 6046 +- 1398 SE goitred gazelles, 1674 +- 506 SE Asian wild asses and 909 +- 303 SE argalis. Discrepancies between population estimates of ungulates in our survey and previous surveys are discussed with regard to methods used and robustness of results obtained. We also discuss conservation implications for wild Bactrian camels and other Mongolian ungulates.

	Title	Habitat segregation between sympatric Tibetan argali Ovis ammon hodgsoni and blue sheep Pseudois nayaur in the Indian Trans-Himalaya			Type	Journal Article
	Year	2004	Publication	Journal of Zoology	Abbreviated Journal
	Volume	262	Issue		Pages	57-63
	Keywords	argali; Ovis ammon hodgsoni; blue sheep; pseudois nayaur; Habitat selection; resource partitioning; niche relationship; 5200
	Abstract	Tibetan argali Ovis ammon hodgsoni and blue sheep Pseudois nayaur have almost completely overlapping distributions encompassing most of the Tibetan plateau and its margins. Such a sympatric distribution of related species with similar ecological requirements implies that there is some degree of resource partitioning. This may be accomplished on the basis of habitat and/or diet separation. This study evaluated such ecological separation on the basis of physical habitat partitioning by these two sympatric ungulates in Hemis High Altitude National Park, Ladakh, India, in an area where the argali established a small new population in 1978. Such separation was tested for on the basis of expected difference between the species in their proximity to cliffs, associated with species-specific anti-predator behaviour. Tibetan argali selected habitats away from cliffs while blue sheep selected habitats close to cliffs. Blue sheep also selected steep slopes whereas argali selected gentle slopes. The two species did not differ in their use of habitats in terms of elevation. They did, however, differ in their use of plant communities; blue sheep selected sub-shrub and grass-dominated communities whilst argali selected forb-dominated communities. We suggest that the two species coexist in this site as a result of the differential use of habitat associated with their species-specific anti-predator strategies.

	Title	Vigilance behaviour of the Tibetan argali Ovis ammon hodgsoni in the Indian Trans-Himalaya			Type	Journal Article
	Year	2007	Publication	Acta Zoologica Sinica	Abbreviated Journal
	Volume	53	Issue		Pages	195-200
	Keywords	Tibertan argali, Ovis ammon, vigilance, dilution effect, Ladakh, Trans-Himalaya
	Abstract	An inverse relationship between individual vigilance level and group size is widely reported in many behavioral studies on animals across several taxa. It is generally held that such a relationship is due to a reduced probability of an individual being killed in larger groups. in the present investigation, I studied the vigilance behavior of the endangered Tibetan argali Ovis ammon hodgsoni in relation to group size and escape terrain. I hypothesized that an individual argali has a higher vigilance level in smaller groups and in habitats closer to cliffs than individuals living in larger groups and open areas (escape terrain). The results show that the vigilance of argali decreased with increasing group size, but there was no effect of escape terrain on its vigilance behavior. There were significant differences between age-sex groups: male, female and yearling in their time budgets. Females, compared to males and yearlings, spent more time being vigilant. They also foraged more and moved less than males. It is suggested that vigilance is an important anti-predator behavior amongst argali sheep.

	Title	Status and trends of Tibetan plateau mammalian fauna, Yeniugou, China			Type	Journal Article
	Year	1999	Publication	Biological Conservation	Abbreviated Journal
	Volume	87	Issue		Pages	13-19
	Keywords	argali; blue sheep; China; conservation; Qinghai; survey; Tibetan antelope; Tibetan gazelle; Tibetan wild ass; white-lipped deer; wild; yak; Yeniugou; 5210
	Abstract	We conducted surveys focusing on the unique and vulnerable ungulate species in Yeniugou, Qinghai province, China, during September 1997 to compare population estimates with those from the early 1990s. The status of two ungulate species appeared essentially unchanged since 1990ñ1992: wild yak Bos grunniens (about 1200 to 1300 animals) and Tibetan gazelle Procapra picti- caudata. The status of one ungulate species, the white-lipped deer Cervus albirostris, appeared to improve, from a very few to close to 100. We are unsure how the status of the Tibetan wild ass Equus kiang compares with that of the early 1990s. The status of three species declined during the period: blue sheep Pseudois nayaur and argali Ovis ammon declined slightly (possibly due to a weather event), and the Tibetan antelope Pantholops hodgsoni declined dramatically (probably due primarily to poaching), from over 2000 estimated in 1991 to only two seen during 1997. Poaching of antelope has become a serious problem throughout the Tibetan plateau in recent years, and this survey provides evidence that an entire subpopulation can disappear (either through mortality, movement away from human disturbance or a combination) within a relatively short time-frame. That some species (e.g. wild yak, white-lipped deer) continue to thrive in Yeniugou is heartening, but even they remain vulnerable to market-driven poaching.#1998 Elsevier Science Ltd.

	Title	Conflicts between traditional pastoralism and conservation of Himalayan ibex (Capra sibirica) in the Trans-Himalayan mountains			Type	Journal Article

	Abstract	There is recent evidence to suggest that domestic livestock deplete the density and diversity of wild herbivores in the cold deserts of the Trans-Himalaya by imposing resource limitations. To ascertain the degree and nature of threats faced by Himalayan ibex (Capra sibirica) from seven livestock species, we studied their resource use patterns over space, habitat and food dimensions in the pastures of Pin Valley National Park in the Spiti region of the Indian Himalaya. Species diet profiles were obtained by direct observations. We assessed the similarity in habitat use and diets of ibex and livestock using Non-Metric Multidimensional Scaling. We estimated the influence of the spatial distribution of livestock on habitat and diet choice of ibex by examining their co-occurrence patterns in cells overlaid on the pastures. The observed co-occurrence of ibex and livestock in cells was compared with null-models generated through Monte Carlo simulations. The results suggest that goats and sheep impose resource limitations on ibex and exclude them from certain pastures. In the remaining suitable habitat, ibex share forage with horses. Ibex remained relatively unaffected by other livestock such as yaks, donkeys and cattle. However, most livestock removed large amounts of forage from the pastures (nearly 250 kg of dry matter/day by certain species), thereby reducing forage availability for ibex. Pertinent conservation issues are discussed in the light of multiple-use of parks and current socio-economic transitions in the region, which call for integrating social and ecological feedback into management planning.

	Title	Animal – Habitat relationships in high altitude rangelands			Type	Manuscript
	Year	2008	Publication	PhD Thesis	Abbreviated Journal
	Volume		Issue		Pages	150
	Keywords	high altitude, homogeneous, argali, habitat selection, resource selection function, ENFA, stratified random sampling, sexual segregation, SSAS, livestock, predation, resources
	Abstract	This study conducted in the high altitude rangelands of Indian Transhimalaya, deals with basic questions regarding the ecology of an endangered species, the wildsheep Tibetan argali (Ovis ammon hodgsoni) and applied issues related to its conservation and potential conflict with the local nomadic pastoralists. The basic questions on ecology are aimed at delineating the habitat and resource selection processes, identifying factors causing sexual segregation and efficient surveying and sampling. The applied aspect focuses on the changing face of pastoralism and the potential impacts of modernising livestock husbandry on argali. Overall, the study provides a general framework towards the understanding of argali-habitat relationships at different spatio-temporal scales. The spatial determinant associated with altitude in the area, predicts argali habitat and resource selection in this relatively homogenous landscape. These determine the range of other topographic variables and forage characteristics selected by argali. The selection of feeding patches in the selected range of altitude and topography is mainly characterised by their greenness and the quality of plant groups. Adjusting to changing forage quality, argali display an opportunistic feeding strategy, selecting grasses in early spring and switching to forbs later in summer. Nevertheless, the habitat selection process did not appear to differ among the sexes to drive sexual segregation. There was, however, strong segregation among the sexes as well as between lactating and non lactating females. The reasons for segregation appeared to be predominantly social, but driven ultimately by predation and concomitantly by resources. The habitat selection information was used to design a stratified random sampling strategy that led to i) a significant reduction in survey effort in sampling these sparsely distributed species and ii) reduction in sampling bias. The applied aspect of the study outlines and evaluates the dramatic changes in the nomadic pastoralism that have occurred in the past five decades in the study area. These have led to a loss of pastures (-25 to -33%) of the nomads, consequent readjustment in traditional patterns of pasture use, intensified grazing pressures (25 to 70%) and rangeland degradation in the area. Such changes may have serious consequences on the survival of local wildlife, as tested with a study of the effects on argali of livestock presence and resource exploitation. Hence, a successful conservation and recovery strategy should focus on: minimising the impacts of livestock on argali, identifying the factors affecting the persistence of the current populations, increasing local sub populations of this species to prevent extinction due to stochastic events, prevent loss of genetic diversity and excessive fragmentation and thus ensuring gene flow. Ecological Niche Factor Analyses (ENFA), bias-reduced logistic regression and Fuzzy correspondence analyses (FCA) were used to answer habitat and resource selection questions. A sexual segregation and aggregation statistic (SSAS) was used to estimate the components of sexual segregation and test segregation. SSAS combined with canonical correspondence analyses (CCA) allowed the estimation of segregation based on habitat variables. Logistic regression models were formulated to estimate models on which the stratified random sampling strategy was based. The 9 Animal – Habitat relationships in high altitude rangelands overall study also included surveys, interviews and literature reviews to understand the nomads’ movement and pasture use patterns of their livestock. Kernel density estimations (KDE) were used to estimate extent of range overlaps between livestock and argali.

	Title	Ibex. Rare ungulate species of the Almaty nature reserve and their protection			Type	Miscellaneous
	Year	1976	Publication		Abbreviated Journal
	Volume		Issue		Pages	141-154
	Keywords	Kazakhstan; Almaty nature reserve; ungulates; number; aerial census; goitered gazelle; argali; ibex; predators; wolf; snow leopard; poaching; disturbance.; 8750; Russian
	Abstract	Collected are data on rare ungulates in the Almaty nature reserve in 1968-1973. Since recently the population of goitered gazelle has dropped sharply and is now 20-30 animals per seven ha. The nature reserve shall be expanded in order to protect the animals. Argali inhabits a desert area in the mountains of Greater and Lesser Kalkana. Argali sometimes migrates outside the nature reserve. Ibex inhabits a mountainous part of the nature reserve, its population being 10-13 animals per 1,000 ha. Predators have negligible impact on the ibex population (12.5 percent of deaths), which is preyed on solely by snow leopard and wolf.
