| Title | Reappraisal of the role of big, fierce predators | Type | Miscellaneous | ||
| Year | 2008 | Publication | Biodiversity Conservation | Abbreviated Journal | |
| Volume | Issue | Pages | 685-690 | ||
| Keywords | Biodiversity ú Conservation ú Costs of predation ú Indirect effects ú Non-lethal effects ú Predators ú Top-down control; big; predators; predator | ||||
| Abstract | The suggestion in the early 20th century that top predators were a necessary component of ecosystems because they hold herbivore populations in check and promote biodiversity was at Wrst accepted and then largely rejected. With the advent of Evolutionary Ecology and a more full appreciation of direct and indirect effects of top predators, this role of top predators is again gaining acceptance. The previous views were predicated upon lethal effects of predators but largely overlooked their non-lethal effects. We suggest that conceptual advances coupled with an increased use of experiments have convincingly demonstrated that prey experience costs that transcend the obvious cost of death. Prey species use adaptive behaviours to avoid predators, and these behaviours are not cost-free. With predation risk, prey species greatly restrict their use of available habitats and consumption of available food resources. Effects of top predators consequently cascade down to the trophic levels below them. Top predators, the biggies, are thus both the targets of and the means for conservation at the landscape scale. |

| Abstract | Background: Predation risk declines non-linearly with one's own vigilance and the vigilance of others in the group (the 'many-eyes' effect). Furthermore, as group size increases, the individual's risk of predation may decline through dilution with more potential victims, but may increase if larger groups attract more predators. These are known, respectively, as the dilution effect and the attraction effect. Assumptions: Feeding animals use vigilance to trade-off food and safety. Net feeding rate declines linearly with vigilance. Question: How do the many-eyes, dilution, and attraction effects interact to influence the relationship between group size and vigilance behaviour? Mathematical methods: We use game theory and the fitness-generating function to determine the ESS level of vigilance of an individual within a group. Predictions: Vigilance decreases with group size as a consequence of the many-eyes and dilution effects but increases with group size as a consequence of the attraction effect, when they act independent of each other. Their synergetic effects on vigilance depend upon the relative strengths of each and their interactions. Regardless, the influence of other factors on vigilance – such as encounter rate with predators, predator lethality, marginal value of energy, and value of vigilance – decline with group size. |

| Title | A snow leopard conservation plan for Mongolia | Type | Report | ||

| Abstract | The snow leopard faces multiple threats in the Himalayan region, from habitat degradation, loss of prey, the trade in pelts, parts and live animals, and conflict with humans, primarily pastoralists. Consequently, the populations are considered to be in decline and the species is listed as Endangered in the IUCN's Red List. As a 'flagship' and 'umbrella' species the snow leopard can be a unifying biological feature to raise awareness of its plight and the need for conservation, which will benefit other facets of Himalayan biodiversity as well. Some studies of snow leopards have been conducted in the Himalayan region. But, because of its elusive nature and preference for remote and inaccessible habitat, knowledge of the ecology and behaviour of this mystical montane predator is scant. The available information, however, suggests that snow leopards occur at low densities and large areas of habitat are required to conserve a viable population. Thus, many researchers and conservationists have advocated landscape-scale approaches to conservation within a regional context, rather than focusing on individual protected areas.This regional strategy for WWF's snow leopard conservation program is built on such an approach. The following were identified as important regional issues: 1) international trade in snow leopards and parts; 2) the human-snow leopard conflict; 3) the need for a landscape approach to conservation to provide large spatial areas that can support demographically and ecologically viable snow leopard metapopulations; 4) research on snow leopard ecology to develop long-term, science-based conservation management plans; and 5) regional coordination and dialog. While the issues are regional, the WWF's in the region have developed 5-year strategic actions and activities, using the regional strategies as a touchstone, which will be implemented at national levels. The WWF's will develop proposals based on these strategic actions, with estimated budgets, for use by the network for funding and fund-raising. WWF also recognizes the need to collaborate and coordinate within the network and with other organizations in the region to achieve conservation goals in an efficient manner, and will form a working group to coordinate activities and monitor progress. | ||||

| Keywords | Kazakhstan; Altai; large predators; snow leopard; distribution; number; preys.; 6110; Russian | ||||
| Abstract | Fauna of large predatory mammals in the Kazakhstan Altai is represented by five species: wolf, bear, glutton, lynx, and snow leopard. Snow leopard inhabits the Sarymsakty and Tarbagai ridges and South Altai. This species is observed to regularly penetrate into the Kutun and Kurchum ridges. Its habitat covers an area of 1,800 sq. km, its population being 14-16 animals. The population density is 0.7 1.0 animals per 100 sq. km. A hunting area of a female animal with two cubs is 45 85 sq. km; a male 120 sq. km. Snow leopard main preys on ibex (41.1 percent), roe-deer (31.0 percent), and moral (13.8 percent); in summer on gray marmot (28.6 percent). Snow leopard is also known to prey on hares, birds, argali, and elks. | ||||

| Title | A Regional Perspective for Snow Leopard Conservation In the Indian Trans-Himalaya | Type | Conference Article | ||

| Abstract | The Trans-Himalaya is a vast biogeographic region in the cold and arid rain-shadow of the Greater Himalaya and is spread over three Indian states. From the conservation standpoint this region has several unique characteristics. Unlike most other biogeographic regions of the country, it has wildlife, including large mammals, spread over the entire region. Another feature is that the harsh climate and topography provides limited agricultural land and pastures, all of which are currently utilized by people. The harsh environment has given rise to a specialized assemblage of flora and fauna in the region that include the endangered snow leopard, a variety of wild sheep and goat, Tibetan antelope, Tibetan gazelle, kiang and wild yak. The snow leopard is one of the most charismatic species of the Trans-Himalaya. This apex predator, with a wide distribution, has ecological importance and international appeal, and is eminently suitable to be used as both a 'flagship' and an 'umbrella species' to anchor and guide conservation efforts in the Trans-Himalayan region. Among the 10 Biogeographic Zones in the country, the Trans-Himalaya has a comparatively large Protected Area (PA) coverage, with over 15,000 km2 (8.2 %) of the geographical area under the network. In spite of this, the bulk of the large mammal populations still exist outside the PAs, which include highly endangered species such as snow leopard, chiru, wild yak, Ladakh urial, kiang and brown bear. Given the sparse resource availability in the Trans-Himalaya and the existing human use patterns, there are few alternatives that can be provided to resource dependent human communities in and around PAs. The existing PAs themselves pose formidable conservation challenges and a further increase in their extent is impractical. The problem is further compounded by the fact that some of the large PAs have unclear boundaries and include vast stretches that do not have any direct wildlife values. These issues call for an alternative strategy for conservation of the Trans-Himalayan tracts based on a regional perspective, which includes reconciling conservation with development. In this paper we stress that conservation issues of this region, such as competition for forage between wild and domestic herbivores and human-wildlife conflicts need to be addressed in a participatory manner. We suggest an alternative scheme to look at the zonation of existing PAs and also the Trans-Himalayan region as a whole, to facilitate better conservation in the region. Also, we emphasize that there is a vital need for additional resources and a formal setup for regional planning and management under a centrally sponsored scheme such as the 'Project Snow Leopard'. |

| Abstract | The snow leopard has remained little studied in the past, and most of the information available is either in the form of natural history or anecdotal notes. The inaccessibility of the terrain and its secretive habits make this one of the more difficult animals to study in the wild. In the past decade, several ecological surveys were conducted in India, Nepal, China and Mongolia, which gave us information on the status and distribution of snow leopard (Jackson, Mallon, Fox, Schaller, Chundawat) A detailed study in Nepal through light on its secretive habits ( Jackson and Ahlborn, 1989). Even then little is known about its feeding habits. The present paper discusses this aspect from a study which was part of a detailed study conducted on the ecology of snow leopard in India from October 1987 to Feburary 1990. | ||||
