    Spatial pattern in the occupancy and abundance of red junglefowl (Gallus gallus) in western Shivalik landscape, India.
    (Wildlife Institute of India, Dehradun, 2015) Fernandes, Merwyn; Sathyakumar, S.; McGowan, Phillip
    This study was to identify landscape-level patterns of distribution, abundance and habitat occupancy of G. gallus across different spatial and temporal scales in a forest landscape, to help guide strategies for Galliformes conservation management. The present study was undertaken in an area (29˚54’ to 30˚24N and 77˚32’ to 79˚12’ E) that is situated within the Shiwalik Hills of Northwestern India, in the districts of Dehradun and Haridwar in Uttarakhand State. G. gallus is listed as a ‘Least Concern’ species, making an assessment of their status requires reliable information on population size and distributions. The structural component of understorey was one of the most important factor that determined occupancy and detection probabilities for the species. The structural components are known to provide cover to G.gallus, and other gallinaceous species that nest on the forest floor. The main threat to G. gallus is hybridisation and hence there is an urgent need to assess ranging patterns, survivorship and other basic demographic parameters, population status, genetic variability and purity of G.gallus in areas adjoining PAs where most of these forests have multiple uses and domestic/feral fowls are in close proximity in order to keep the common species common.

    Asiatic Black Bear (Ursus thibetanus) Abundance, Habitat Occupany Patterns, and Conflicts with Humans in and around Dachigam National Park, Kashmir.
    (Wildlife Institute of India, Dehradun, 2012) Charoo, Samina Amin; Sathyakumar, S.
    The present study focused on the abundance estimation, habitat use patterns and human - bear interactions in Dachigam National Park and Dachigam Landscape, Jammu and Kashmir, India during the period 2007-2010. The abundance estimation is the basic information needed for any species. In this study abundance estimation of black bears was tried out through various methods: sign surveys, camera trapping and non- invasive genetic method. Sign surveys were carried out to understand the encounter rates of black bears within Dachigam National Park.

    Habitat Ecology of major ungulates in Kedarnath musk deer sanctuary, Western Himalaya.
    (Wildlife Institute of India, Dehradun, 1994) Sathyakumar, S.; Johnsingh, A.J.T.
    Present study on the habitat ecology of major ungulates in Kedarnath Wildlife Sanctuary "(WS) was conducted from March 1989 to November 1991. The objectives of this study were to de,!elop suitable techniques for estimating ungulate abundance and density; to study their habitat utilization pattems; and to assess the status of ungulates and their habitats in different parts of the Kedarnath WS.
