Shifts in amphibian population dynamics in response to a change in the predator community

Predation can affect prey behavior, demography, abundance, and distribution, particularly in lentic freshwater ecosystems. Fish are predators known to reduce the abundance of their prey and to restrict the distribution of species. Using time series which spanned 43 and 22 yr, respectively, we analyzed the effect of a change in the fish predator community on the dynamics of two pond-breeding amphibian populations (Rana temporaria and Rana dalmatina).  Leer más.
