In animals with complex life cycles, the cost of migration among habitats has to be balanced by optimization of growth and survival within each life-stage habitat. In this context, migration distance is expected to depend on local density and movement potential. In ectotherm species, because movement potential is related to body size, larger individuals are expected to cover longer distances than smaller individuals thus avoiding competition. This hypothesis was investigated in the agile frog (Rana dalmatina
