    Ecology of Golden jackal (Canis aureus) in Sariska Tiger Reserve, Rajasthan
    (Wildlife Institute of India, Dehradun, 2015) Chourasia, Pooja
    This study aimed to examine the abundance and occupancy of jackal with the application of photographic captures using camera traps and diet composition through scat analysis, investigate species-habitat relationships from habitat features (non-spatial) and remotely sensed features (spatial) to understand how these variables govern occurrence pattern and predict the distribution of jackal in Sariska Tiger Reserve, Rajasthan. In India, jackal populations achieve high densities in pastoral areas such as Kutch, Maharashtra, Rajasthan, and Haryana. This study will vitally improve our state of knowledge to protect jackal and assist the development of theory on their social structure, behavior and habitat preferences in forested ecosystem. The study will help in suggesting localized monitoring mechanisms wherever necessary as this is important in minimizing surprise cases of extinction. The objectives of this study are as follows:-1. To determine the abundance of golden jackal. 2. To estimate the food availability, food habits and dietary niche overlap between golden jackal and other meso-carnivores.3. To evaluate the den site selection by golden jackal and, 4. To evaluate the habitat use by golden jackal. The study was conducted from 2010-2013 in Sariska Tiger Reserve (79° 17’ to 76°34’N and Latitude: 27° 5’ to 27° 33’ E), Rajasthan. Selected 160 km2 of intensive study area which was divided into four blocks. A total of 160 locations were selected for the placement of camera traps where, each block having 21 camera trap stations. Peafowl was observed to be the most abundant prey species throughout the study period. Amongst the wild prey species, nilgai was observed to be the most abundant wild ungulate prey species followed by, chital, wild pig and sambar in the study area..The Species distribution data was collected from camera trapping, direct sighting records, scat locations and track locations and was pooled for the entire study period 2010-2013, collectively making 413 observed point locations in the intensive study area.

    Systematics, phylogeography and population genetics of the Golden Jackal, Canis aureus
    (Wildlife Institute of India, Dehradun, 2013) Negi, Tripti; Jhala, Y.V.
    The goal of this study was to elucidate the systematics, phylogeny, population genetic structure, genetic variability and the relationship of golden jackal in relation to other canid species. The study outline the general characteristics of family Canidae and golden jackal as a typical member of the family, the theory of conservation genetics, molecular genetics, and the molecular markers, taxonomic affiliation of golden jackal to other jackal species and to resolve their global higher level phylogenetic status in the genus Canis and population genetic structure and genetic variability among golden jackal in Western India, Gujarat.

    Home Range, Ranging Patterns and Abundance Estimation of Golden Jackals in the BHAL Region of Gujarat
    (Wildlife Institute of India, Dehradun, 2001) Aiyadurai, Ambika; Jhala, Y.V.
    Studied Golden Jackals (Canis aureus) in the Bhal area of Gujarat using radiotelemetry. Six jackals were trapped in Velavadar.National Park during November and December 2000 using rubber-padded leg-hald traps. The average home range size of jackals was estimated to be 14. 30 ± 4.06 sq. km. The core areas of jackal home ranges were highly correlated with vegetation cover. Habitats preferred for core areas were Prosopis juliflora and grasslands. Jackals ranged an average distance of 6.8 ± 0.91 km in a night. Most movements were out of the park to surrounding villages, which were rich in food resources for jackals. I evaluated two techniques to estimate jackal abundance namely the track plot method and simulated howling responses method in six areas differing in jackal abundances in the Bhal and Kutch regions. The latter technique gave a better resolution of abundance categories within the study sites.
