摘要：

An aggregate of local populations of the leopard frog, Rana blairi, exists in extreme southeastern Arizona. The populations appear to be geographically isolated from the main body of the species in the central United States. In Arizona, the frog occurs sympatrically with the southern form of leopard frog (an unnamed species of the R. pipiens complex), but natural hybrids have not been identified. Differences in mating vocalizations and partial genetic incompatibility seem to represent the primary form of reproductive isolation, although incomplete differences in breeding period also might function as a minor barrier.
