Understanding sioth bear (Melursus ursinus) Genetic Connectivity across Vidarbha Landscape, Maharashtra, India

Abstract

The goal of this thesis is to use non-invasive DNA sampling to study how sloth bears roam throughout the Vidarbha region of Maharashtra, India. Maharashtra's Vidarbha Landscape is a quickly changing area. The great biodiversity that lives there is under risk from the quick changes in the landscape. It's vital to note that there are about 200 instances of deadly human-sloth bear interactions in Maharashtra alone each year, and that number could increase in the years to come due to increased development activities in the area. Wide ranging or long dispersing species who have extensive movements across a landscape are the ones most affected by range contraptions and fragmentation of the habitat. The broad objectives of this thesis were 1. Understand Genetic Structure, Variation and relatedness amongst sloth bear populations in Vidharbha Landscape and 2. Evaluate genetic relatedness with respect to permeability of the landscape and connectivity. The functional corridor obtained for sloth bears is the main result of this thesis. This can be used in a number of ways by managers, planning bodies, and stakeholders. First, the occupancy and connection would assist indicate key movement regions and areas of concern when evaluated in conjunction with the documented incidents of sloth bear attacks. The pinch points could be focused upon and conserved as intact corridors. Secondly, the movement areas could be modelled with documented bear attacks to highlight the probable corridors or movement areas that need awareness to avoid bear attacks
