Abstract

In order to assess local population differentiation of a ranid frog Rana nigrovittata within Thailand and to elucidate its phylogenetic relationship with R. mortenseni, we surveyed a total of 72 frogs belonging to eight populations using starch gel electrophoresis. Rana nigrovittata is genetically substantially differentiated among populations, and can be divided into two groups with Nei's D of 0.23. Rana mortenseni from the Ko Chang Island is closest to the far inland northeastern population in the UPGMA tree and specific separation of this form from R. nigrovittata is not supported at least for the Thai population. Genetic differentiation of the two major groups of R. nigrovittata is not small compared with those reported for other anuran species. The pattern of geographic variation among populations of R. nigrovittata seems to have been strongly affected by the geohistory of their distributional ranges.
