摘要:

Although the dominant burnsi gene is widely distributed in Minnesota populations of the leopard frog (Rana pipiens) at uniformly low frequencies, estimates of the effective size of the breeding populations suggest that a wider range of gene frequencies might be expected due to random genetic drift. Observations of the spring, summer, and fall migrations, however, indicate a level of migratory activity sufficient to prevent local divergence in gene frequencies. Temperature appears to play a major role in the springtime migratory and breeding behavior of Rana pipiens in Minnesota.
