Respuesta Antidepredatoria de Osos Hormigueros (Myrmecophaga tridactyla) Mantenidos en Cautividad

Abstract

Resumen Muchos mamiferos son capaces de percibir y responder al riesgo de depredacion a partir de senales emitidas por sus depredadores, aun en ausencia de una experiencia ecologica, evolutiva e incluso de ambas. Sin embargo, se ha propuesto que el cautiverio puede afectar dicho comportamiento debido probablemente a los costos que acarrean para las presas el conservar las conductas antidepredatorias. En el presente trabajo se analizo la respuesta de osos hormigueros (Myrmecophaga tridactyla) mantenidos en zoologicos (n=7) al ser expuestos a estimulos olfativos y auditivos de un depredador natural (yaguarete, Panthera onca). Para ello se comparo la respuesta comportamental que tenian frente a heces y vocalizaciones de yaguarete con aquella desplegada frente a senales de aguara guazu (Chrysocyon brachyurus), un carnivoro simpatrico no-depredador, y oveja (Ovis aries), una especie inocua alopatrica. Los resultados mostraron que los osos hormigueros en cautiverio conservan la capacidad de responder y discrimi...
