India, Jan. 16 -- The Aravalli hill range is a keystone ecological system in western India. While it is commonly associated with limiting the eastward spread of the Thar Desert, its more critical function lies in acting as a major biological corridor, enabling species movement, genetic exchange and long-term landscape-level biodiversity persistence.

Biological corridors are broadly categorised into upland corridors, formed by elevated terrains, and lowland corridors, such as riverine and drainage networks. The Aravalli range constitutes one of India's most significant upland corridors, facilitating wildlife dispersal and seasonal migration across biogeographic zones. Concurrently, rivers and rivulets along both flanks of the range create...
