The relationship between population structure and amount of genetic variation within populations has been investigated in seven species of anurans from Southeast Asia. Two populations each of Bufo asper, B. parvus, B. melanostictus, Rana blythi, and R. erythraea and one population each of R. hosei and R. laticeps were studied; all except B. melanostictus and R. erythraea are forest species. Information on distributional characteristics such as general habitat, form of the adult range, the relationships of nonbreeding range to breeding site, the tendency to aggregate at the breeding site, and the size of the breeding aggregation was used to outline major aspects of the breeding structure of each species and predict relative amounts of genic variation. Genetic variation was estimated from measures of protein polymorphism as detected through gel electrophoresis. The assays used were liver EST, FUM, GDH, LAP, LDH, MDH, and total protein; muscle EST, GOT, MDH, and total protein; plasma EST and total protein. The pattern of variation of the populations of Bufo species agreed with predictions based on population structure, with B. asper the least polymorphic, B. melanostictus the most polymorphic, and B. parvus intermediate. Interspecific differences were not as great in Rana as in Bufo. Although R. erythraea was more variable than R. blythi in terms of mean number of morphs per zone (as predicted from distributional characteristics), R. blythi possessed polymorphism at more zones. R. hosei was the most polymorphic Rana studied, but distributional data are insufficient to explain why this was the case.
