Abstract
Diversity, evenness, richness, ecological distribution, niche breadth and niche overlap of amphibian assemblages in the protected areas of amphibian assemblages in the protected areas of Kerala were determined. The amphibian assemblages studied in all the protected areas showed high diveristy in composition and distribution of species. The study of species distribution indicated the presence of hightly organised natural communities. The amphibian communities at these areas show greater ecological similarity among coexisting species. The amphibian assemblage was composed of some abundant species together with rare specialists. This pattern indicated that the protected areas are undergoing natural succession towards accommodating rare species along with the common species by gradually occupying the niche hyerspace available.
