Abstract

Present study for documentation of Amphibian diversity and their habitat preference was conducted for 1 year. Survay was conducted during the period January 2023 to December 2023 at 3 different study sites of Sheohar district Bihar. Nine amphibian species belonging to 4 families and 7 genera were found at different study sites viz. Rani Talab, Giriza Bag and Zero Mile area in Sheohar district of Bihar. Out of the 9 recorded amphibian species all the 9 amphibian species were found and identified in and around the Rani Talab (Site-I) area, 7 amphibian species recorded in and around the area of Giriza Bag (Site-II) area and 5 amphibian species were recorded in and around the Zero Mile (Site-III) area of Sheohar district Bihar. 4 amphibian species (D. melanostictus, D. stomaticus, H. tigerinus & P. maculatus) was found at all study sites, Whereas 2 amphibian species (S. braviceps & F. limnocharis) was found only at site-I. Statistical analysis of the collected data on amphibian diversity of this district revealed Shannon-Wiener species diversity index was minimum (1.557) at site-III and maximum (2.105) at site-I. Margalef richness index value was minimum (0.8846) and maximum (1.565) at site-I. In contrast to these values evenness was maximum (0.9484) at site-III and minimum (0.9115) at site-I.
