    Ecology of striped hyena (Hyaena hyaena) in Sariska Tiger Reserve, Rajasthan
    (Wildlife Institute of India, Dehradun, 2019) Mandal, Dibyendu K.; Sankar, K.; Qureshi, Qamar
    This study was conceivedto fill gaps in our understanding of striped hyena population parameters, resource utilization and their sociality. Finally, the findings were synthesized to understand the processes shaping diverse sociality of striped hyenas across varying resources in a comparative context under the framework of RDH. The present study was undertaken in Sariska Tiger Reserve (STR), a protected area situated in the semi-arid region of North-Western India. STR is an isolated system which has a sharp boundary with human habitations.

    Ecology of sympatric small carnivores in Mudumalai Tiger Reserve, Tamil Nadu
    (Wildlife Institute of India, Dehradun, 2013) Kale, Riddhika; Sarkar, K.; Qureshi, Qamar
    This study aimed to examine the abundance and occupancy of small carnivores with the application of photographic captures using camera traps and diet composition of small carnivores through faecal analysis, investigate seasonal species-habitat relationships from microhabitat (non-spatial) and remotely sensed features (spatial) to understand how these variables govern their occurrence pattern and predict the distribution of small carnivores in Mudumalai Tiger Reserve, Western Ghats. The study was conducted from 2009-2011 in Mudumalai Tiger Reserve (11°32' 11°43'N; 76°22'-76°45'E), Western Ghats. This study will critically improve our state of knowledge to protect lesser carnivores and aid the development of theory on their social structure, behavior and habitat preferences.Study species include jungle cat (Felis chaus), leopard cat (Prionailurus bengalensis), rusty spotted cat (Prionailurus rubiginosus), common palm civet (Paradoxurus hermaphroditus), small Indian civet (Viverricula indica), brown palm civet (Paradoxurus jerdoni), grey mongoose (Herpestes erdwardsii), ruddy mongoose (Herpestes smithii) and stripe-necked mongoose (Herpestes vitticollis). The objectives of this study area as follows:- 1. To determine the abundance and occupancy of small carnivores in Mudumalai Tiger Reserve. 2. To study the dietary pattern of small carnivores. 3. To determine spatial and non-spatial variables governing the occupancy of small carnivores and 4. To predict the distribution pattern of small carnivores through habitat suitability modeling in Mudumalai Tiger Reserve.

    Ecology of leopard (Panthera pardus) in Sariska Tiger Reserve, Rajasthan
    (Wildlife Institute of India, Dehradun, 2011) Mondal, Krishnendu; Shankar, K.; Qureshi, Qamar
    The present study estimated the prey availability and prey consumption, population and survival rate and the home ranges and resource selection of leopard in Sariska Tiger Reserve. The Sariska Tiger Reserve (STR) (N27o05’ to N27o45’ and E76o15’ to E76o35’) is situated in the Aravalli Hill Range and lies in the semi-arid part of Rajasthan for four consecutive years from 2007 to with these objectives: 1. To estimate the prey availability of leopard 2. To study the food habits and prey selection of leopard 3. To estimate the population of leopard and 4. To study the home range and habitat use of leopard. In the present study, food habits and prey selection of leopard were examined during the study period following scat analysis method and kill records. Radio-telemetry technique was followed to estimate the home range and habitat use of leopard as this technique is found to be the most updated and useful practice to gather information on home range, daily and seasonal movement pattern of big cats. The result of this study presented the abundance of prey species of leopard and their consumption by leopard in Sariska TR. The study also estimated the population and survival rate of leopard in Sariska TR. Home range and habitat use of leopard was estimated in the present study and a habitat suitability model for leopard was generated in and around Sariska TR.

    Ecology of medium and small sized carnivores in Sariska Tiger Reserve, Rajasthan
    (Wildlife Institute of India, Dehradun, 2011) Gupta, Shilpi; Sankar, K.; Qureshi, Qamar
    To assess wildlife population trends, scientifically based monitoring programs must be carried out. A new generation of camera traps and the use of well developed capture-recapture models have led to an increase in the use of remote surveying and monitoring methodologies for nocturnal species. Population estimates can be done for individually identifiable cryptic nocturnal species through camera trap. The study was carried out in Sariska Tiger Reserve (STR), western Rajasthan, India, (79° 17’ to 76°34’N, 27° 5’ to 27° 33’ E) from November 2007 to June 2009. The objectives of study are (1) To estimate the abundance of medium and small sized carnivores such as striped hyena, jackal, jungle cat, civets and mongoose. (2) To study the prey availability and food habits of medium and small sized carnivores and To assess the habitat suitability for these carnivores. In this study, both capture - recapture method and Royle -Nichols (2003) approach was applied to photographic capture trap data to estimate density and abundance of nocturnal cryptic species. The results of this study presented both numerically and also in the form of habitat suitability maps for all the study species in the study area. These finding have potential to develop basis for managing areas for these medium and small sized carnivores in Sariska and other similar habitat in semi arid zone.
