Item Ungulates mediated effects on Vegetation Structure and Biomass in Panna Tiger Reserve, Central India(Wildlife Institute of India, Dehradun, 2023) Gupta, Deepti; Ramesh, K.; Rawat, G.S.Ungulates play an important role in shaping the plant community structure, species richness and distribution through herbivory, seed dispersal, trampling and adding nutrient to the soil.They also act as important component of food chain, and hence their abundance and distribution are directly related to the large carnivore survival. Distribution of ungulates is strongly influenced by plant phenology, spatial heterogeneity of the forage plants and seasonal rhythm. Ungulates having different body sizes, habitat preferences, and anti-predator strategies might show a range of responses to the vegetation structure and composition (tree density, basal area and species richness), habitat parameters (terrain complexity, water availability and slope) and anthropogenic pressure (cattle abundance and human proximity). Ungulates in tropical dry deciduous forests have been majorly studied as primary prey to large carnivores. Panna Tiger Reserve (PTR), situated in the Vindhyan mountain ranges in Madhya Pradesh, central India, between 24°27¢N to 24°46¢N latitude and 79°45′E to 80°09′E longitude. PTR is uniquely characterized by its 'terraced topography' and presents two tabletop mountains and a valley formed by the Ken River. For this study, I chose four ungulates species having different habitat preferences, dietary requirements and body size viz., sambar (primarily a browser), chital (primarily a grazer), Nilgai (mixed feeder) and wild pig (omnivorous). Research objectives are as follows:1. To determine the vegetation structure and composition and quantify the above-ground biomass 2. To estimate the density of ungulates across space and seasons. 3. To model the ungulates-habitat relationships and related functional responses.Item A study on habitat use and food habits of swamp deer (Cervus duvauceli duvauceli) in Jhilmil Tal, Haridwar Forest Division, Uttaranchal(Wildlife Institute of India, Dehradun, 2009) Tiwari, Rachna; Rawat, G.S.Habitat use and food habits of the swamp deer (Cervus duvauceli duvauceli) were studied in and around Jhilmil Jheel Conservation Reserve (JJCR), Uttarakhand, during June 2006 and June 2008. This population of swamp deer was recently rediscovered in the state and warranted an ecological study and conservation initiative because the habitat around this study area is heavily fragmented due to expansion of agriculture, habitation and various other land use practices. Therefore, this study was initiated. The major objectives were: i. ii. iii. To study seasonal variation in habitat use pattern and food habits, Activity pattern, Population structure and habitat condition, and iv. Identify threats and suggest conservation measures. Habitat evaluation of various potential (but fragmented) habitat blocks in Jhilmil Jheel Conservation Reserve area and surrounding Banganga wetland revealed that they bear a close resemblance with the prime swamp deer habitat both in terms of structure and composition of key habitat variables.Item Systematics and ecology of Berberidaceae in Uttarakhand state.(Wildlife Institute of India, Dehradun, 2012) Banerjee, Kausik; Rawat, G.S.; Adhikari, B.S.In the present study Population estimation, Habitat loss, Ranging pattern, Food habits and other parameters were discussed.
