    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.

    Movement and space use pattern of Tigers in the Eastern Vidarbha landscape, Maharashtra, India
    (Wildlife Institute of India, Dehradun, 2024) Hussain, Zehidul; Habib, Bilal
    Movement is a crucial ecological process that influences the survival, population dynamics, and evolution of animals. Animal movement patterns are diverse and are influenced by life stages, sex, age, and habitat requirements. The relationship between animal movement and conservation is complex, particularly due to human-induced environmental changes This study emphasises that various factors influence animal movement, including individual characteristics and external factors such as resource availability, distribution, competition, and predation. Animals adjust their space use based on seasonal changes in resource availability. Additionally, movement patterns and space use can be influenced by habitat disruption, forcing individuals to displace and establish new home ranges. Landscape features play a significant role in animal home ranges, with resource distribution determining the extent of the required area. Fragmentation of habitats and human activities can affect landscape connectivity, leading to isolation, reduced gene flow, and potential genetic bottlenecks or local extinctions. Thus, maintaining habitat connectivity is crucial for long-term survival of highly mobile species. The study highlights the need for comprehensive datasets and technological advancements, such as GPS tracking, to study animal movement and behaviour. It also emphasises the importance of studying dispersal patterns, as dispersed individuals often encounter humandominated landscapes and face increased vulnerability to anthropogenic effects. This study focused on quantifying movement patterns and space use across three life stages: predispersal, dispersal, and post-dispersal phases. The results revealed differences in space use within and outside protected areas, with individuals outside protected areas requiring larger territories. The study also identified seasonal variations in space use and movement patterns, with dispersed tigers exhibiting the highest space use. Land-use composition, landscape configuration, and anthropogenic disturbances influence the use of tiger space. These findings provide insights into the factors influencing tiger movement and space use in a human-dominated landscape. They highlighted the importance of maintaining habitat connectivity, reducing anthropogenic disturbances, and restoring suitable habitats outside protected areas to facilitate dispersal and ensure the long-term survival of tigers.
