Abstract |
A survey of Himalayan Thar was carried out in Langtang valley in response to the lacking of scientific information of its population status and distribution in the area. The study was carried out from Ghodatabela to Langsisa Kharka during April to June of 2003/04/2005. The area was divided into 5 survey blocks measuring 5sqkm each and study was conducted through blocks. Observed herds and individual animals were repeatedly counted and recorded. A total of 218 individuals of different age and sex Himalayan Thar were recorded during the study in 8 different herds. Three types of herds were recognized; Adult male-adult female-young (37.5%), Adult female-young (37.5%) and All adult-male (25%). Survey revealed that 50% of Thar herds were observed in 4200-4900m (Fourth block) and least (12%) were in 3700-4000m (First block), animals were not located in 3850-4200m (Third, Fifth block). Stratified random sampling was done to analyze the vegetation in their habitat and identified 26 potential plant species. The encroachment of their habitat is severe by the excessive livestock grazing and utilization for cowshed. Noticeable disturbance felt due to frequent poaching and tourist flow. The conservation of this species seems vital as it is prime prey species of Snow leopard in LNP. |

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. |

Abstract |
Many years' data connected with the distribution and number of endangered species of animals as dhole (Cuon alpinus Pall), striped hyena (Hyaena hyaena L.), snow leopard (Uncia uncia Shreb.) and birds of Tajikistan are given. Area of snow leopard includes the most of mountain ridges in this country. The total number is evaluated about 160-200 individuals. The record quantity of legal harvested skins of snow leopard is 64 in 1946. |

Abstract |
Snow leopard is an endangered species. Its number is steadily decreasing. In the USSR, snow leopard is distributed in the mountains of Central Asia: Pamir, Tien Shan, Djungar Ala-Tau, Tarbagatai, Saur. It is also met at altitudes ranging from 1,800 3,500 m above sea level. A total number of snow leopard in the USSR does not exceed 1,000 animals; according to other data 2,000 animals. A decreasing number of snow leopard and its habitat shrinkage is directly related to human's pursuing snow leopards (in the USSR snow leopard was for a long time being considered as a species causing damage to livestock so authorities gave premiums for catching/shooting snow leopards) and reduction of ungulate population. Snow leopards are now protected in mountain nature reserves of the USSR: Chatkal, Aksu-Djabagly, Ramit, Besh-Aral, Sary-Chelek, and Alma-Ata. |

Abstract |
In Tajikistan it is necessary to preserve big predators listed in the Red Book, such as Uncia uncia, Ursus arctos isabellinus, Hyaena hyaena, Felis lynx isabellina, Panthera pardus ciscaucasica. An anthropogenic influence has resulted in the species' habitat shrinkage, deficit of food, disturbance of trophic interactions. It is necessary to restore a tiger population in the Tigrovaya Balka nature reserve, and resolve the issue of protection and sustainable use of commercial predatory species. |
