Habitat occupancy and influence of abiotic factors of the occurrence of Nyctibatrachus major (Boulenger) in central Western Ghats, India

Habitat features and influence of abiotic factors on the occurrence of Nyctibatrachus major in the streams of central Western Ghats was studied by comparing microhabitat variables of the streams inhabited and those streams not inhabited by frogs. The study reveals the requirement of low concentrations of carbon dioxide, alkalinity and high concentrations of dissolved oxygen under low air, water and soil temperatures. Further, analysis of abiotic factors and density of the frog reveals that concentration of carbon dioxide in water directly influences on the occurrence of the species, while other factors in combination determines the suitability of the habitat
