This paper demonstrates the effect of habitat heterogeneity and a habitat preference on the genetic structure of a hybrid zone between the toads Bombina bombina and B. variegata (Anura: Discoglossidae); 1613 toads from 85 sites across a transect near Pešćenica, Croatia, were scored for five unlinked diagnostic allozyme markers. These were found to be largely concordant. Aside from minor systematic deviations, there was little variance in allele frequency among loci within sites. Yet the allele… CONTINUE READING
