Abstract

Widely distributed species often show interpopulation variation. Studying such variations can be helpful in understanding contributing factors and distinguishing widespread species and species complexes. We studied six populations of Hylarana malabarica distributed along the northern Western Ghats of India using morphometric and genetic analysis. Of 24 size-adjusted morphometric characters, 14 were significantly different among populations. Hierarchical clustering and discriminant analysis of morphometric characters suggested that the six populations form at least four distinct clusters. Analysis of morphometric data was supported by genetic polymorphism data obtained by the Randomly Amplified Polymorphic DNA (RAPD) method. Since the similarity and variation observed among populations was independent of their spatial distribution, it is possible that this widely-distributed species may be a species complex.
