    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.

    A Whistle Amongst Growls : Dholes in a Multi Predator System in Dry Deciduous Forests of India
    (Wildlife Institute of India, Dehradun, 2015) Ghaskadbi, Pallavi; Habib, Bilal; Qureshi, Qamar
    A significant amount of research has proved that there is a positive correlation between habitat heterogeneity/diversity and animal 'species diversity owing to the availability of more exploitable niches (Tews et al. 2004). On a spatial scale for free ranging large carnivores, a place like the Tadoba- Andhari Tiger Reserve has a low habitat heterogeneity, however, it shows a variety of species of both predators and prey in a small area. Studying the prey- predator interactions in such a system would lead to a better insight into large carnivore ecology. In contrast with the African Wild dog which enjoys much more attention of researchers and biologists, the Dhole has clearly not been a favourite. Being a social carnivore, there is a complex and dynamic fission and fusion of packs amongst Dholes. However, there is a grave lack of information on the pack dynamics of the Dhole. I attempted to conduct experiments to study one of the fundamental factors of social behaviour which is individual recognition.
