    Tiger and leopard: Population ecology and resource portioning of sympatric carnivores in Kanha Tiger Reserve. M.P.
    (wildlife Institute of India, Dehradun, 2020) Kumar, Ujjwal; Jhala, Y.V.; Qureshi, Qamar
    Large investment in the form of protected areas, human resettlement, law enforcement-patrols and habitat management are made to conserve tigers and reap their benevolent umbrella role to secure India’s biodiversity. The objectives of present study are (i) the trend of tiger and leopard population (ii) demography of tigers and leopards and mechanism of their co existence. The study area was Kanha tiger reserve (area 2074 km2), a major stronghold for both species in central Indian landscape. Study investigate the estimated vital parameters of tiger demography through robust design based classical open population models in which population was open to demographic process. This study used both camera trap based mark-recapture and continuous monitoring known fate information to estimate reproductive parameters along with age specific survival and dispersal probability of tigers.

    Understanding aspects of demography and resource partitioning mechanisms of large felids among with abundance and spatial distribution of prey in Similipal Tiger Reserve, Odisha
    (Wildlife Institute of India, Dehradun, 2024) Rathore, Harshvardhan Singh; Pandav, Bivash; Jhala, Y.V.
    This study investigates the crucial aspect of coexistence for large predators like tigers and leopards sharing the same landscape and delves into the population dynamics of these animals by identifying the mechanisms of resource partitioning. By acting as a window into the inner workings of the ecosystem, the study reveals how tiger and leopard populations function alongside each other. Identifying the factors that influence their ability to share the resources successfully is vital for developing more effective conservation strategies. This knowledge ultimately contributes to ensuring the long-term survival of both tigers and leopards in this landscape. A precise assessment of several demographic parameters is necessary to make informed management decisions for their conservation within this unique habitat. These parameters include population density, sex structure, recruitment, and survival rates. With this background, the study comes with the following objectives. (1) To assess the abundance and spatial distribution of prey in STR.(2) To assess the various demographic parameters of large felids (tiger and leopard) in STR. (3) To determine the mechanisms of resource partitioning of the tiger and the leopard in STR. Similipal Tiger Reserve is located in the Mayurbhanj district of Odisha, between86˚06' and 86˚36' East longitude and 21˚31' and 22˚02' North latitude. The study was carried out over three years (2019–2021) across eight ranges in the core area of STR: Chahala, Nawana North, Nawana South, and Pithabata South Wildlife in the northern core, and UBK, Jenabil, Bhanjabasa, and National Park in the southern core.
