Article Synopsis
  • Humans have significantly altered natural habitats, leading to isolated patches that threaten genetic diversity and increase the risk of inbreeding among species.
  • The study focuses on gaur and sambar populations in central India, using innovative genomic techniques to analyze how habitat fragmentation affects gene flow and connectivity.
  • Results show that gaur populations are highly fragmented and genetically distinct, while sambar populations display variable genetic structure, indicating that different species respond uniquely to landscape changes, emphasizing the need for multi-species conservation strategies.

Human demographic expansion has confined wildlife to fragmented habitats, often in proximity to human-modified landscapes. Such interfaces facilitate increased interactions between feral or domesticated animals and wildlife, posing a high risk to wild species. This is especially relevant for free-ranging dogs () and wild canids like gray wolves () and golden jackals ().

Tigers continue to face unprecedented threats to their existence due to poaching, habitat loss, habitat fragmentation and anthropogenic disturbances. The present study examines the physiological stress response of tigers due to anthropogenic activities including wildlife tourism in Bandhavgarh Tiger Reserve and Kanha Tiger Reserve using faecal glucocorticoid metabolite (fGCM) measurement. We collected a total of 341 faecal samples from both reserves during tourism and non-tourism periods.
