    Behavioural patterns and food habits of re-introduced gaur (Bos gaurus gaurus) in Bandhavgarh Tiger Reserve, Madhya Pradesh.
    (Wildlife Institute of India, Dehradun, 2015) Manjrekar, Manas P.; Sankar, K.; Qureshi, Qamar
    The present study was designed to study the behavioural patterns and food habits of the reintroduced gaur population in Bandhavgarh Tiger Reserve. The study was carried out from March 2012 to February 2014. For the collection of data on the behavioural patterns of gaur the scan sampling technique was used and 13 distinct activities of gaur were identified viz. feeding, moving, resting, standing, autogrooming, allogrooming, sexual behaviour, aggressive behaviour, drinking, salt licking, vocalising, defecating/urinating and alert behaviour. In the present study the social interactions among the members of a gaur herd were classified as allogrooming, dominance-subordination interactions and sexual behaviour. Four types of dominance-subordination interactions were recorded among gaur during the study period in Bandhavgarh.

    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.

    The feeding ecology of the Dhole or Asiatic Wild Dog (Cuon alpinus) in Kanha Tiger Reserve, Madhya Pradesh.
    (Wildlife Institute of India, Dehradun, 2008) Acharya, Bhaskar B.; Johnsingh, A.J.T.; Sankar, K.
    In order to collect basic information on the prey species of dholes, this study aimed to estimate the density, encounter rates, biomass, and the population structure and composition of the major prey species within the study area. Eventually, The objective of this study was to determine the relative proportions of different prey species in diet of dholes, in terms of frequency of occurrences, biomass, and numbers of individuals consumed. The aim was also to study predation by dholes in relation to prey availability and utilization within Pench Tiger Reserve, i.e. to see if dholes killed prey randomly or selected specific kinds of prey. If that was so, the ecological factors intrinsic to that prey which may influence prey selection were assessed.
