Resumen

Life history trade-offs in reproductive strategy are often invoked as ecological agents of evolutionary change, despite a limited amount of experimental data from the field. The larval deposition strategy of Allobates femoralis was tested in Southeastern Peru using a blocked, fully crossed experimental design. Arrays of four pools were used to test the effects of pool size and the presence of a predatory insect (Belostomatid) on the deposition behavior of A. femoralis. Further experiments investigated the colonization of insect predators into potential larval habitats and interactions between predatory insects. Results suggest that pool size, the presence of predatory aquatic insects, and interactions between predators, influence larval deposition in A. femoralis. Similar ecological interactions may have driven toxic dendrobatids to the use of arboreal phytotelmata and associated derived reproductive strategies.
