    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.

    Movement of Radio-collared tigers in the Eastern Vidarbha Landscape, Maharashtra, India
    (Wildlife Institute of India, Dehradun, 2018) Habib, Bilal; Nigam, Parag; Hussain, Zehidul; Ghaskadbi, Pallavi Surendra
    To understand the movement ecology of tigers in the Eastern Vidarbha Landscape, focusing on individual patterns of space use in general, utilization distribution in different areas and landscape, spatio-temporal activity and effect of environmental features on animal movement, the point-wise objectives are as follows: 1. To understand the movement of tigers that drives population connectivity on a landscape scale and effect of environmental features on dispersal. 2. To validate the modeled corridors and identify new functional corridor and habitats in a highly dynamic landscape. 3. Directly aiding effective conservation and management of tigers beyond the Protected Area (PA) system as a result of real-time data from radio-collars.
