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 (up) 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.

Abstract The snow leopard and it s p rey were investigated in Beita Mountain Region , Xinjiang in Sep . 2004.

Both the field survey and questionnaire were involved in this project which was supported by the International

Snow Leopard Trust and Xinjiang Conservation Fund. The signs marked by the snow leopard were used

to reflect the living condition of snow leopard and they were collected by running transects. The prey investigation was conducted by positioned observation and route survey. Fifteen transects were done in the

project and 67 signs leaved by snow leopard were discovered in total. 58. 2 % of them were scrapes ,

35.8 % of t hem were feces , 4.5 % of them were claw rakes and 1. 5 % of them were scent

spray. As to the prey resources , 4 herds of 23 ibex and 24 herds of 418 chukars were found during the survey. Also 81 local people of 5 different nationalities were interviewed during the field work , 13.

58 % of them had seen the snow leopard , 20. 99 % of them had heard of snow leopard but not seen. Among t hem , 10 herdsmen had sufferred from the loss of livestock attacked by snow leopard.

Title Wild sheep and livestock in Nepal Trans-Himalaya: coexistence or competition? Type Journal Article
Year 2008 Publication Environmental Conservation Abbreviated Journal
Volume 32 Issue 2 Pages (up) 125-136
Keywords bharal; blue sheep; diet; food habits; mountain ungulates; Nepal; pastoralism; pseudois nayaur; rangeland management; resource partitioning
Abstract Excessive grazing by livestock is claimed to displace wild ungulates in the Trans-Himalaya. This study compares the seasonal diets and habitat use of sympatric wild naur Pseudois nayaur and domestic goat Capra hircus, sheep Ovis aries and free-ranging yak Bos grunniens in north Nepal and analyses their overlap both within and across seasons. Alpinemeadow and the legumes Oxytropis and Chesneya were critical resources for all animal groups. High overlap occurred cross-seasonally when smallstock (sheep and goats) in summer used the spring and autumn ranges of naur. Relatively high total ungulate biomass (3028 kg km-2) and low recruitment of naur (56 young per 100 adult females in autumn) suggested interspecific competition. The spatio-temporal heterogeneity in composition and phenology of food plants across the steep gradient of altitude, together with rotational grazing, appears to indirectly facilitate coexistence of naur and smallstock. However, owing to high crossseasonal (inter-seasonal) overlaps, competition is likely to occur between these two groups at high stocking densities. Within seasons, naur overlapped more with free-ranging yak than with smallstock. As their habitat use and diets were most similar in winter, when both fed extensively on the same species of shrubs, naur was most likely to compete with yak during that season.

Title Common and snow leopards share prey, but not habitats: competition avoidance by large predators Type Journal Article
Year 2013 Publication Journal of Zoology Abbreviated Journal
Volume 291 Issue Pages (up) 127-135
Keywords coexistence; resource partitioning; food habits; Panthera uncia; Panthera pardus.
Abstract Resource exploitation and behavioural interference underlie competition among

carnivores. Competition is reduced by specializing on different prey and/or spatiotemporal

separation, usually leading to different food habits. We predicted that

two closely related species of large cats, the endangered snow leopard and the

near-threatened common leopard, living in sympatry, would coexist through

habitat separation and exploitation of different prey species. In central Himalaya,

we assessed (2006–2010) habitat and diet overlap between these carnivores. The

snow leopard used grassland and shrubland, whereas the common leopard

selected forest. Contrary to our prediction, snow leopard and common leopard

preyed upon similar wild (Himalayan tahr, musk deer) and domestic species (Bos

spp., dogs). Dietary overlap between snow leopard and common leopard was 69%

(yearly), 76% (colder months) and 60% (warmer months). Thus, habitat separation

should be the result of other factors, most likely avoidance of interspecific

aggression. Habitat separation may not always lead to the use of different prey.

Avoidance of interspecific aggression, rather than exploitation of different

resources, could allow the coexistence of potentially competing large predators.

Title Animal – Habitat relationships in high altitude rangelands Type Manuscript
Year 2008 Publication PhD Thesis Abbreviated Journal
Volume Issue Pages (up) 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 Competition between domestic livestock and wild bharal Pseudois nayaur in the Indian Trans-Himalaya Type Journal Article
Year 2004 Publication Journal of Animal Ecology Abbreviated Journal
Volume 73 Issue Pages (up) 344-354
Keywords blue sheep,diet,grazing,rangeland,resource,ungulate,wildlife; 5320
Abstract 1. The issue of competition between livestock and wild herbivores has remained contentious. We studied the diets and population structures of the mountain ungulate bharal Pseudois nayaur and seven species of livestock to evaluate whether or not they compete for forage. The study was conducted in the high altitude Spiti Valley, Indian Trans-Himalaya.

2. We compared resource (forage) availability and bharal population structures between rangelands differing in livestock density. Forage availability was estimated by clipping the standing graminoid biomass in sample plots. Livestock and bharal population structures were quantified through annual censuses. Seasonal diets of livestock were studied by direct observations, while those of bharal were quantified through feeding

signs on vegetation.

3. We found that livestock grazing causes a significant reduction in the standing crop of forage. Graminoid availability per unit livestock biomass was three times greater in a moderately grazed rangeland compared with an intensively grazed one.

4. There was considerable diet overlap among the herbivore species. In summer, bharal, yak Bos grunniens, horse Equus caballus, cow Bos indicus, and dzomo (yak-cow hybrids) fed predominantly on graminoids, while donkey E. asinus, sheep Ovis aries, and goat Capra hircus, consumed both graminoids and herbs. The summer diet of bharal was a subset of the diets of three livestock species. In winter, depleted graminoid availability caused bharal, yak and horse to consume relatively more herbs, while the remaining livestock species fed predominantly on graminoids. Diet overlap was less in winter but, in both seasons, all important forage species in the bharal diet were consumed

in substantial amounts by one or more species of livestock.

5. Comparison of the population structures of bharal between two rangelands differing in livestock density by

c. 30% yielded evidence of resource competition. In the intensively grazed rangeland, bharal density was 63% lower, and bharal population showed poorer performance (lower young : adult female ratios).

6.Synthesis and applications High diet overlap between livestock and bharal, together with density-dependent forage limitation, results in resource competition and a decline in bharal density. Under the present conditions of high livestock density and supplemental feeding, restricting livestock numbers and creating livestockfree areas are necessary measures for conserving Trans-Himalayan wild herbivores. Mediating competitive effects on bharal through supplemental feeding is not a feasible option.

Title The sacred and the scientific: Traditional ecological knowledge in Siberian River conservation Type Journal Article

Abstract The Katun River originates in the steppe of the Altai Mountains in Siberia. One of the major headwaters of the Ob River, the Katun is considered central to the culture of the indigenous Altaians. The Katun Valley contains large numbers of important cultural sites, dating from the Neolithic and representing some of the earliest human settlement in Russia. Modern-day Altaians still observe traditional ceremonies honoring the river and springs throughout the watershed and utilize traditional ecological knowledge in their management of the land and water resources. Russian and international scientists have identified the Altai Mountains as a region of high plant diversity and endemism, and as important habitat for endangered species such as the snow leopard. The Katun River itself contains species of threatened and endangered fishes, and its headwaters are part of the unusual Mongolian ichthyofaunal province that is characterized by high levels of endemism. The same regions are considered by the Altaian people to be special or sacred and are recognized by Western scientists as having great value for conservation. During the era of perestroika, a hydroelectric dam was to be built on the Katun. The large dam, a vestige of the earlier Soviet plan for the Project of the Century, would have devastated significant agricultural, ecological, recreational, and cultural resources. The indigenous Altaian people would have lost much of their sacred and cultural landscape. The Katun dam project united indigenous people, well-known Siberian writers, and scientists in protest, which became so heated that it engaged the international community, with lasting effects on Russian society. The magnitude of the protest illustrates the importance of the Altai Mountain region to all of Russia. The active participation of indigenous Altaians reflected their traditional willingness to take action against political decisions that negatively impacted the environmental, cultural, and religious values of their homeland. Their involvement also reflected the new wave of awareness under perestroika that underscored a greater respect and autonomy for indigenous peoples in Russia.
