Abstract

Predator-prey relationships have been studied relentlessly throughout all different taxa and systems. Larval anurans use the mode of chemosensory to detect and avoid predation. By exposing Bufo marinus tadpoles to a variety of natural chemicals (crushed conspecific larvae and metamorphs, and crushed annelid prey) a strong repulsion was demonstrated. Avoidance of the treatments verified that Bufo marinus tadpoles are sensitive to changes in the chemical make-up of their environment that could be caused by a predator in close proximity.

Resumen

Las relaciones de depredador-presa se han estudiado implacablemente a través de todos los diversos taxones y sistemas. Los anurans larvales utilizan el modo de quimiosensoriales para detectar y para evitar la depredación. Exponiendo a los renacuajos Bufo marinus a una variedad de productos químicos naturales (las larvas y los metamorphs aplastados y la presa anélida aplastada) se demostró una repulsión fuerte.
