    Evaluating methods to monitor tiger abundance and its prey in Indian Sunderbans
    (wildlife Institute of India, Dehradun, 2019) Roy, Manjari; Sankar, K.; Qureshi, Qamar
    This study conducted to test and evaluate different methods for estimating tiger and its prey population in Sundarban that can be adopted as part of a monitoring programme. For this study techniques were applied for the standard spatially explicit capture-recapture, tailored according to the local conditions to estimate tiger density in Sundarban for three years. Tiger densities were estimated at 4.08 (SE 1.51) in 2010, 5.81 (SE 1.24) in 2012 and 3.15 (SE 0.88) tigers/100 km2 in 2014. The tiger abundance for my camera trapped study area generated through conventional mark-recapture was 11 (SE 2), 24 (SE 3) and 16 (SE 3) tigers for 2010, 2012, 2014 respectively. Ungulates occupy a primary position in the diet of tigers and a monitoring protocol for tiger should inherently include a component of prey base estimation. Boat transect based distance sampling to generate density estimates for four years.

    Prey selection and food habits of large carnivores: tiger (Panthera tigris), leopard (Panthera pardus) and dhole (Cuon alpinus) in Mudumalai Tiger Reserve, Tamil Nadu.
    (2010) Ramesh, T.; Sankar, K.; Qureshi, Qamar
    A detailed long-term study on prey selection, food habits and population status of three sympatric large carnivores (tiger, leopard and dhole) was documented during the present study. To supplement the current basic information, the present study was conducted in Mudumalai Tiger Reserve, Tamil Nadu from January 2008 to April 2010. The objectives of the study include estimating density, group size and composition of prey species of sympatric carnivores, to study the food habits and prey selectivity of sympatric carnivores and to estimate the population of the sympatric carnivores. Prey selection and food habits of large carnivores were studied using two methods i.e by evaluating kills and analyzing scat. Data on population estimation of dhole was collected between January 2008 and December 2009. Five vehicle transect routes ranging from 15 to 23 km were monitored to record dhole sightings. Camera-trap and vehicle transect studies have showed that high densities of large carnivores in the study area of the Tiger Reserve.

    Food habits of tiger (Panthera tigris tigris) in Sariska tiger reserve, Rajasthan
    (Wildlife Institute of India, Dehradun, 2003) Avinandan, D.; Sankar, K.; Qureshi, Qamar
    The present study aims at understanding relationship between tiger and its prey in a semi arid tract. The study was conducted in Sariska tiger reserve, Rajasthan over a period of six months from November 2002 to April 2003. Density estimation of major wild and domestic prey species was done to assess availability to tigers in terms of density and biomass. The line transect method was used to estimation prey density

    Food Habits of Tiger (Panthera tigris tigris) in Pench National Park, Madhya Pradesh
    (Wildlife Institute of India, Dehradun, 1999) Biswas, Sayentan; Sankar, K.; Chundawat, R.S.
    Food habits of tiger was studied in a dry deciduous forest area in Pench National Park, Madhya Pradesh over a period of 6 months from November 1986 to April 1999. Density estimation of major prey species was done to assess availability to tigers. Line transect method was used for estimation of prey density. Scat analysis revealed that chital constituted the major part of is tiger prey followed by sambar and wild pig.
