Annual climatic fluctuations and short-term genetic variation in the eastern spadefoot toad

Abstract In addition to variations on the spatial scale, short- and long-term temporal variations, too, can impose intense selection on the overall genetic diversity and composition of a population. We hypothesized that the allelic composition in populations of the eastern spadefoot toad (Pelobates...
