    Status and spatio-temporal ranging behavior of leopard (Panthera pardus) in Dachigam National Park, Srinagar, J&K.
    (Wildlife Institute of India, Dehradun, 2021) Noor, Athar; Habib, Bilal; Gopi, G.V.
    This study was initiated by Wildlife Institute of India, Dehradun with support funding from the Department of Science and Technology (DST), Government of India, in December 2010 to December 2013 to estimate leopard population and prey abundance, to study the leopard feeding habits and to determine the ranging behavior of leopards in Dachigam National Park. This thesis is an outcome of the main study and has three main objectives. The first objective being to determine the population status of leopards; second is to study the ranging behaviour and habitat use by leopards and lastly to model habitat suitability for leopards in Dachigam National Park. This study also provides basic information about co-occurrence of mammalian species in the community of the moist temperate forest of the Kashmir Himalaya, India

    Evaluating the use of Camera-Traps for population estimation of unmarked individuals using spatially explicit models in Tadoba-Andhari Tiger Reserve, Maharashtra, India
    (Wildlife Institute of India, Dehradun, 2021) Chatterjee, Nilanjan; Habib, Bilal
    Wildlife monitoring is of fundamental importance to establish baseline information, measure population changes and extinction risk. Motion-triggered camera traps are an increasingly popular tool for monitoring terrestrial species over large landscapes. Over the years, the application of camera traps has increased exponentially but studies aiming at fundamental information about sampling design and protocols are still limited to simulation studies. In this dissertation, we have used occupancy as an indicator of effective species monitoring. Occupancy has become a robust and unbiased state variable to monitor species worldwide. However, the optimal sampling design required for robust estimations of occupancy is lacking for many species.The Tadoba-Andhari Tiger Reserve (TATR) is situated in the Chandrapur district in the the Vidharbha Landscape of Maharashtra state, between 204’53” to 2025’51’’ N and 7913’13” to 79 33’34” E (Figure 6). The TATR is distributed over an area of 1700 sq. km which consists of Tadoba national park and Andhari wildlife sanctuary.

    Understanding Wolf Howls and their application in individual identification and population estimation
    (Wildlife Institute of India, Dehradun, 2022) Sadhukhan, Sougata; Habib, Bilal
    The current study addresses the knowledge gap about Indian wolf vocalisation. Alongside, it focuses on the identification potentiality of wolf howl to an individual level for using them in population estimation through mark-capture-recapture. The study also includes the howling behaviour and responses of the Indian wolf to various ecological and anthropogenic factors. Understanding the howling behaviour is key for designing howl survey methods for wolf census. As howl survey is a technique to detect wolves over long distances, the technique might provide a cost-effective solution for population estimation and a noninvasive monitoring tool for Indian wolves in human-dominated landscapes.
