    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.

    Response of small carnivore community to landscape and climatic variability in the Great Himalayan National Park Conservation Area, the Western Himalaya
    (Wildlife Institute of India, Dehradun, 2022) Bandyopadhyay, Meghna; Ramesh, K
    This study will add knowledge about the elusive and lesser-known small carnivores in a gradient of disturbed and less disturbed habitats. Objectives The study focusses on the following objectives: 1) Occurrence and abundance estimation of small carnivores across space and time along the elevation gradient. 2) Assessment of community composition of small carnivores and association with other small carnivore species. 3) Evaluation of landscape sensitivity by representative small carnivore species. 4) Distribution modelling of indicator species to anthropogenic and climatic effects in the current context Study focusses on the arrangements of small carnivores along the elevation gradient in terms of site intensity usage and abundance of small carnivores. Marked (leopard cat) and unmarked (red fox) species were considered and statistical models were used to find the overall abundance and also across the elevation gradient in space and time. demonstrates the coexistence patterns of small carnivores (red fox and leopard cat) in three dimensions; space, time and diet. The niche dynamics was assessed and compared between low human disturbance and high human disturbance areas. Study reveals how the coexistence patterns of small carnivores change with differential human disturbances.
