Abstract


Genetic relationships among six species of the genus Rana from Korea were investigated by complete nucleotide sequence analyses of mitochondrial cytochrome b gene (1143 bp). Based on Kimura?2?parameter distance, the interspecific sequence differences of cytochrome b gene within the genus Rana were ranged from 7.83% to 25.00%. The genetic distances were 7.83% between R. nigromaculata and R. plancyi, 8.47% between two types of R. rugosa (type A and B), 16.42% between the brown frogs (R. amurensis and R. dybowskii), 16.11% between R. dybowskii types 1 and 2 and 12.36% between pond frogs (R. nigromaculata and R. plancyi) and R. catesbeiana. In the neighbor?joining and parsimony trees, R. catesbeiana was more closely related to pond frogs than brown frogs. R. dybowskii types 1 and 2 were considered to be at a distinct and specific level of differentiation (16.11%), while two types of R. rugosa were suspected to be at a sub?specific level (8.47%).
