Item Phylogeography and population genetics of leopards (Panthera pardus fusca) in India(Wildlife Institute of India, Dehradun, 2024) Bhatt, Supriya; Mondol, SamratThis study based on assessment of genetic variation, phylogeography and demographic history among Indian leopards. It also deals with the local population dynamics of leopards in the Rajaji tiger reserve where utilization of microsatellite markers was done. MtDNA and Microsatellite markers used for the study. Non-invasive genetic approaches to understand the various aspects of species biology focusing on phylogeography, demography, and local population dynamics in this study. The major objectives of this proposed thesis are: a) To assess the phylogeography of the Indian leopards using mtDNA and microsatellite markers b) To evaluate the population structure and demographic history of leopards in the Indian subcontinent using both mtDNA and microsatellite markers c) To investigate leopard social dynamics using genetic data at the local level and examine how it varies across different densities.Item A report on population and density estimation of leopards in Girnar Wildlife Sanctuary, Gujarat(Wildlife Institute of India, Dehradun, 2012) Jhala, Y.V.; Basu, ArnabItem Spatial analysis of livestock predation by leopards in the Greater Gir Landscape(Wildlife Institute of India, Dehradun, 2019) Jhala, Y.V.; Vasavada, D.T.; Gogoi, K.; Chakrabarti, S.Data on livestock kill by leopard were collected from the districts of Junagadh, Amreli, Gir Somnath and Bhavnagar, accounting for 711 villages between 2012 to 2016. These data were further translated into English, digitized and spatially mapped in GIS. We obtained remotely sensed as well as spatial covariate layers of forest cover, refuge patches, drainages and nigh-light intensity. We conducted a fixed Kernel analysis of spatially explicit livestock predation events at the village resolution to obtain a consolidate “predation risk map” by leopards of the landscape and used it for subsequent analysis. The tehsils of Talala, Sutrapada, Kodinar, Visavadar, Palitana, Gir Gadhada, Junagadh, Una and Mendarada recorded highest livestock predation by leopards. A temporal increasing trend was observed for number of leopard-predation events as well as in the spatial extent of predations. However, the intensity (number of livestock kills/village/year) of livestock predation did not show any increasing trend, this suggests that though there is an increase in the geographical extent of conflict, the intensity in a given area has remained constant. This could be interpretate as geographical range exapansion of the leopard without increasing its density within occupied areas. Proximity to wildlife habitats, proportion of wildlife area and urbanization enhanced chances of leopard predation. A significant deficit between the market rate and compensated amount for leopard predation was observed with an increasing trend. As a management strategy we recommend a revision of compensation rates to match the market price and an efficient system to pay compensation promptly. Improved husbandary practices and, as well as managing leopard density below social carrying capacity is recommended. This would help maintaining tolerance towards leopards under an increasingly conflict scenario. iiItem Status of leopards in India 2018(Wildlife Institute of India, Dehradun, 2018) Jhala, Y.V.Leopard abundance was estimated at the scale of four major tiger conservation landscapes 1) Shivalik Hills and Gangetic plains, 2) Central India and Eastern Ghats, 3) Western Ghats and, 4) North Eastern Hills and Brahmaputra Flood Plains. this exercise not only comes up with tiger numbers for the country but also evaluates the status of co-predators, prey, habitat and human disturbance parameters for all tiger occupied forested landscapes of the country.
