    Aspects of Sloth bear (Melursus ursinus) Ecology in Sanjay Tiger Reserve, Madhya Pradesh
    (Wildlife Institute of India, Dehradun, 2022) Chaudhuri, Sankarshan; Sathyakumar, S.; Sankar, K.; Qureshi, Qamar
    This study was conducted to identify the aspects of the ecology of sloth bear. I conducted the fieldwork for this study for three years (2017-2019). The broad objectives of this study were: 1. To estimate the occupancy and abundance of sloth bears and identify environmental and anthropogenic factors which influence the same 2. To assess the space use patterns by sloth bears in terms of habitat use and den selection 3. To investigate the seasonal diet patterns of sloth bears 4. To assess the human-sloth bear conflict based on spatio-temporal interaction.

    Determinants of occurrence of snow leopard and its prey species in the Indian Greater and Trans Himalaya.
    (Wildlife Institute of India, Dehradun, 2017) Ghoshal, Abhishek; Pandav, Bivash; Bhatanagar, Yash veer
    Understanding patterns of species occurrences and how their distribution and abundance are affected by abiotic and biotic factors have been a major theme of ecological research. The range and changes in the distribution of a species are important parameters to assess conservation status. Robust assessment of factors affecting species distribution and abundance contribute to the identification of conservation issues, appropriate scale(s) for species conservation and key stakeholders. This study is attempted to understand how distribution and abundance of a large-ranging and difficult-to-sample carnivore and its primary wild-prey species are affected by topographic, vegetation and land-use variables, at wide and fine spatial scales. Study is focused on the snow leopard (Panthera uncia), the elusive, rare and endangered apex predator of the Central and South Asian mountain systems, and its main prey, blue sheep or bharal (Pseudois nayaur) and Asiatic ibex (Capra sibirica) for the work. I have utilized tools from quantitative ecology and social sciences through the thesis.
