    Resource partitioning among sympatric ungulates in Kanha Tiger Reserve, Madhya Pradesh, India.
    (wildlife Institute of India, Dehradun, 2021) Awasthi, Neha; Jhala, Y.V.; Qureshi, Qamar
    This study explores the potential mechanisms of how the community of sympatric ungulates in Kanha might partition resources by evaluating i) habitat-specific seasonal densities and spatial co-occurrence of ungulates; ii) demographic parameters; iii) temporal activity and food habits of ungulates and; iv) factors affecting their group size. The study area was ~ 2074 km2 Kanha Tiger Reserve comprising inviolate Kanha National park (core zone; devoid of human settlements and use) and the multiple-use area (buffer zone; consisting of forest and xviii revenue land, used by rural communities for farming and livestock rearing). The study stresses the importance of human free core areas and the need for conservation investments for achieving high ungulate densities and biomass that are essential to sustain source populations of tigers and other endangered carnivores in this landscape.

    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.

    Indian Grey wolves (Canis lupus pallipes) in Human dominated landscape; Movement, space use and foraging
    (Wildlife Institute of India, Dehradun, 2023) Khan, Shaheer; Habib, Bilal
    The study presented a comprehensive investigation into the ecology of Indian wolves (Canis lupus pallipes) within human-dominated landscapes in Maharashtra, India. The study focused on movement patterns, den and rendezvous site selection, and food habits of Indian wolves to gain insights into their adaptation strategies and ecological interactions within changing environments. Seven adult wolves (three males and four females) and four subadult wolves (two males and two females) were captured using soft leghold traps from 2017 - 2021. Trapped wolves were held using a double-threaded nylon hockey net and immobilized using Ketamine–Xylazine by injecting intramuscularly on their hind leg and fitted with GPS collars. A total of ten wolves from seven different packs were fitted with GPS collars, and one male was fitted with a proximity collar. The GPS collars were programmed for the different intervals between positions ranging from 0.5-5 hours per fix (median=1 hour), depending on the time of year and type of individual. I then scaled the data to 1 hour per fix for movement analysis. This research underscores the importance of understanding wolf movement, denning ecology, and food habits for effective conservation strategies. As human populations and habitat alterations increase, studying wolf adaptation is crucial for species-specific conservation planning.

    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.

    An assessment of abundance, habitat use and prey selection by carnivores in Khanchendzonga Biosphere Reserve, Sikkim
    (Wildlife Institute of India, Dehradun, 2013) Bashir, Tawqir; Sathyakumar, S.
    The present study conducted for about five years (2008-2012) was therefore designed to generate some baseline information on the carnivores of the least explored part of the eastern Himalayan biodiversity hotspot i.e., the Khangchendzonga Biosphere Reserve (BR~2,620 km²) with an attempt to assess their diversity, distribution, abundance, space use, food habits, activity patterns and the nature and extent of human-carnivore conflict, if any. An effort was also made to use this information in predicting suitable and priority areas for conservation action and in developing a protocol for long-term population monitoring of these species. Reconnaissance surveys were conducted in seven watersheds of the Khangchendzonga BR and the Prek chu watershed (182 km²) was selected for intensive field work. The study confirmed the presence of 19 species of carnivores from the KBR including 11 species of global conservation significance. In order to understand the factors that govern the co-existence of carnivores in the area their spatial, dietary and temporal patterns of recourse use were also assessed. This study provides the first scientific information on the ecology of carnivores in the Khangchendzonga BR and is of high significance to managers for efficient conservation and management of these ecologically important species and their habitats in such intricate habitats where accessibility and data collection is a limiting factor.

    (2010) Ramesh, T.; Sankar, K.; Qureshi, Qamar
    A detailed long-term study on prey selection, food habits and population status of three sympatric large carnivores (tiger, leopard and dhole) was documented during the present study. To supplement the current basic information, the present study was conducted in Mudumalai Tiger Reserve, Tamil Nadu from January 2008 to April 2010. The objectives of the study include estimating density, group size and composition of prey species of sympatric carnivores, to study the food habits and prey selectivity of sympatric carnivores and to estimate the population of the sympatric carnivores. Prey selection and food habits of large carnivores were studied using two methods i.e by evaluating kills and analyzing scat. Data on population estimation of dhole was collected between January 2008 and December 2009. Five vehicle transect routes ranging from 15 to 23 km were monitored to record dhole sightings. Camera-trap and vehicle transect studies have showed that high densities of large carnivores in the study area of the Tiger Reserve.

    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.
