Abstract: | Although the dominant burnsi gene is widely distributed in Minnesotapopulations of the leopard frog (Rana pipiens) at uniformlylow frequencies, estimates of the effective size of the breedingpopulations suggest that a wider range of gene frequencies mightbe expected due to random genetic drift. Observations of thespring, summer, and fall migrations, however, indicate a levelof migratory activity sufficient to prevent local divergencein gene frequencies. Temperature appears to play a major rolein the springtime migratory and breeding behavior of Rana pipiensin Minnesota. |
