    A study on predation ecology of large carnivores with special reference to human-carnivore conflicts in Pench Tiger Reserve, Madhya Pradesh, Central India
    (Wildlife Institute of India, Dehradun, 2022) Chatterjee, Anindita B.; Sankar, K.; Qureshi, Qamar; Jhala, Y.V.
    Seven years of data (2008 – 2015) resulted in phot-capture of 96 unique individual tigers in the study area. The estimated survival rate of individual tigers was high. Survival of female tigers were higher than that of the male tigers but the range was overlapping. Apparent survival and transitional probabilities were best explained by gender specific models. Survival constant was selected as the best model for estimating growth rate of tigers. Calculated annual growth rate was 13% with no observed sex bias.

    Aspects of Sloth bear (Melursus ursinus) Ecology in Sanjay Tiger Reserve, Madhya Pradesh
    (Wildlife Institute of India, Dehradun, 2022) Chaudhuri, Sankarshan; Sathyakumar, S.; Sankar, K.; Qureshi, Qamar
    This study was conducted to identify the aspects of the ecology of sloth bear. I conducted the fieldwork for this study for three years (2017-2019). The broad objectives of this study were: 1. To estimate the occupancy and abundance of sloth bears and identify environmental and anthropogenic factors which influence the same 2. To assess the space use patterns by sloth bears in terms of habitat use and den selection 3. To investigate the seasonal diet patterns of sloth bears 4. To assess the human-sloth bear conflict based on spatio-temporal interaction.

    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.

    Ranging patterns and habitat use of re-introduced gaur (Bos gaurus gaurus) in Bandhavgarh Tiger Reserve, Madhya Pradesh.
    (Wildlife Institute of India, Dehradun, 2014) Navneethan, B.; Qureshi, Qamar; Sankar, K.
    Bandhavgarh Tiger Reserve (BTR), situated in Central India, supported a small population of gaur (38. individuals) till 1995. This gaur population became locally extinct in 1998, and the reason for the same is attributed to disruption of the migratory corridor between the forests of Bandhavgarh and Ghunghuti and Amarkantak. Even after the local extinction of gaur, BTR continued to be an excellent habitat for gaur and hence it was decided to reintroduce gaur in BTR as it would be a major conservation initiative for this endangered species. The present study on reintroduced gaur was carried out from March 2011 to February 2013 covering all seasons in a year, summer (March - June), monsoon (July - October) and winter (November - February) in Bandhavgarh Tiger Reserve, Madhya Pradesh, Central India, to study the ranging pattern and habitat use.

    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.

    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.

    Habitat Occupancy by Wild Ungulates in Pench Tiger Reserve, Madhya Pradesh
    (Wildlife Institute of India, Dehradun, 1997) Acharya, Bhaskar B.; Sankar, K.
    This study on the habitat occupancy by wild ungulates was carried out from November1996 to April 1997 in the Pench Tiger Reserve, Madhya Pradesh. the spatial and seasonal difference in habitat occupancy of the major forest types by the wild ungulates viz. chital (Axis axis), sambar (Cervus unicolor), gaur (Bas gaurus), nilgai (Boselaphus tragocamelus) were assessed. The study area was stratified into three major forest types based on floristics and physiognomy as: Teak dominant forest, Anogeissus boswellia mixed forest and Miscellaneous forest. A total of 12 transects were laid in three forest types. Data was collected on ungulate densities, dung abundance and habitat parameters. The Line transect Method was used for estimating ungulate densities. Dung abundance was quantified using a belt transect, at each 200 m point on the transects. Habitat parameters were also quantified at these points. The relationship between habitat factors and the distribution of ungulates were examined using bivariate and multivariate analyses. The results showed that chital densities were significantly lower in Teak dominant forest type in winter, and in the Anogeissus boswellia mixed forest type in summer. Both Teak and Misellaneous forest types showed greater chital densities in summer than in winter. Sambar densities showed no significant differences between forest types both in winter and in summer. Anogeissus boswellia mixed forest type showed a significant increase in sambar density from winter to summer. Chital dung abundance showed no significant differences between forest types, both in winter and in summer, while sambar dung abundance in the Anogeissus boswellia mixed forest type was significantly higher that, other forest types in both seasons. There were significant seasonal differences in chital dung abundance in all forest types, whereas sambar dung abundance increased only in the miscellaneous forest type.
