    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.

    Food habits of sympatric large herbivores in Kaziranga National Park, Assam, India
    (Wildlife Institute of India, Dehradun, 2023) Devi, Anita; Hussain, S.A.; Badola, Ruchi
    This study aims to a. address the welfare state of Asiatic lions (Panthera leo persica) based on environmental factors and individual-level differences, and b. propose a methodological framework for evaluation and improvement welfare in captive environments. In this chapter, I will set up the context for this study with a brief chronology of our understanding of the origin of animal welfare and the science of zoo biology and their relevance to the Asiatic lion conservation breeding programme (CBP)

    Ecology and Management of Lion and ungulate habitats in Gir.
    (Wildlife Institute of India, Dehradun, 1995) Sharma, Diwakar; Johnsingh, A.J.T.
    The Gir is the only refuge of the Asiatic lion (Panthera leo persica) in its range. This implies that long term conservation of the Asiatic lion will remain an overirding management objective. A study on the impacts of management practices on lion and ungulate habitat was conducted in Gir Protected Area (PA) from June 1991 to July 1994. The Gir . PA includes Gir Wildlife Sanctuary and National Park. It is situated between 200 55' to 21 0 20 'N and 700 25' to 71 0 15' E in the Southern part of Kathiawar peninsula in western Gujarat. Gir PA (hereafter Gir) is located about 60km South of Junagadh. The area which was .3,107 sq km iIi 1877 (Joshi 1976) has been presently reduced to 1,412 sq km, o~ which about 259 sq Ian is national nark. Gir is the last refuge of the wild Asiatic lions (Panthera leo persica) and long term conservation of the Asiatic lion is an overriding management objective of Gir. In order to improve habitat conditions in Gir, the park authorities, over the last 20-25 years have made some management interventions such as relocation of some maldharis (local graziers), reduction in livestock grazing (specially migrant livestock during the rainy season) and fire control. These measures have led to vegetational recovery and increase in wild ungulate and lion populations. Understanding this vegetational recovery was thought to be crucial to determine the extent of management intervention required. It also needed to be determined if the trend (especially in the western Gir) was toward a higher woody proportion both at shrub and tree levels, and whether this in long term would adversely affect ' the distribution and abundance of ungulates, and therefore, group hunting by the lions, their pride size and territoriality.
