Phylogenetic signal in elevational distribution and range size of a Satyrinae butterfly genus in the Himalaya

Sailendra Dewan, Basundhara Chettri, Sudeep Ghatani, Bhoj Kumar Acharya

Abstract The distribution and community structure of organisms are influenced by both their evolutionary history and ecological interactions. Therefore, it is essential to integrate ecological studies with evolutionary approaches to fully understand the dynamics of species distribution and assembly mechanisms. In this …

Rapoport's rule explains the range size distribution of butterflies along the Eastern Himalayan elevation gradient

Sailendra Dewan, Bhoj Kumar Acharya

Abstract Understanding elevational range size distribution of organisms can provide valuable insights on biogeographic pattern of species and their conservation. Rapoport's rule posits that the elevational range size of species increases with increasing elevation. However, the validity of this rule is often …

Ecological niche modelling of two water-dependant birds informs the conservation needs of riverine ecosystems outside protected area network in the Eastern Himalaya, India

Roshan Tamang, Vallanattu James Jins, Sailendra Dewan, Shivaji Chaudhry et autres

Common species often play vital roles in ecosystem functions and processes. Globally, conservation strategies are mostly focused on threatened species and rarely explored the potential of using common species as indicators of critical ecosystems. The Himalayan mountains have unique riverine ecosystems harbouring …

Turnover in butterfly communities and traits along an elevational gradient in the eastern Himalaya, India

Sailendra Dewan, Nathan J. Sanders, Bhoj Kumar Acharya

Abstract Beta (β)‐diversity varies along environmental gradients, and understanding what drives such variation might provide insights into the factors that shape community structure from place to place. Here, we delineate the spatial pattern of β‐diversity, analyze its underlying mechanisms, and examine variation …
