Dietary Pattern of Asiatic Lions in the Coastal Ecosystem of Saurashtra, Gujarat, India

Abstract

The Asiatic lion (Panthera leo leo), a flagship species of conservation significance, has expanded its range beyond the Gir protected areas into multi-use landscapes, including the coastal regions of Saurashtra, Gujarat, India. This study examines the dietary patterns of Asiatic lions in this unique coastal region. Using scat analysis, we identified the prey species consumed and quantified their contributions to the lions’ diet. Results indicate that the lions predominantly consumed wild prey, such as Boselaphus tragocamelus, Sus scrofa, and Axis axis, which together constituted 64% of their diet. Domestic prey contributed 31%. In terms of biomass, wild prey accounted for 70%, with Boselaphus tragocamelus alone contributing 51%. The dietary niche breadth, calculated using Levin’s index, was 0.36, suggesting a relatively specialized diet. This study underscores the importance of prey abundance and habitat structure in shaping lion predation patterns. Lions’ reliance on wild prey, particularly Boselaphus tragocamelus and Sus scrofa, highlights their crucial role in the coastal region. Additionally, the inclusion of domestic prey, such as feral cattle, may reflect their high availability and reduced anti-predator behaviors. These findings emphasize the need for robust prey population monitoring and habitat conservation to ensure the long-term survival of Asiatic lions in the coastal region.
