Ecología y comportamiento de las ranas venenosas del género oophaga en Costa Rica y Panamá

Abstract

The poison dart frogs Oophaga granulifera and Oophaga pumilio are distributed in Nicaragua (only O. pumilio), Costa Rica and Panama. The ecology and behavior of both species has attracted scientifc attention for several reasons. These frogs exhibit toxicity in combination with bright coloration and diversification into different color morphs. Moreover, they display highly aggressive and territorial behavior, and have a complex mating and parental care system. In this article we summarize recent published data from numerous researchers. We emphasize the link between the behavior (reproduction, territoriality) of the frogs and their resource and habitat use. Additionally we demonstrate how within species variation in the strategies used... (More)

The poison dart frogs Oophaga granulifera and Oophaga pumilio are distributed in Nicaragua (only O. pumilio), Costa Rica and Panama. The ecology and behavior of both species has attracted scientifc attention for several reasons. These frogs exhibit toxicity in combination with bright coloration and diversification into different color morphs. Moreover, they display highly aggressive and territorial behavior, and have a complex mating and parental care system. In this article we summarize recent published data from numerous researchers. We emphasize the link between the behavior (reproduction, territoriality) of the frogs and their resource and habitat use. Additionally we demonstrate how within species variation in the strategies used for predator avoidance (aposematism and crypsis) is associated with the genetic population structure, and correlated with behavioral divergence. We conclude that evolutionary forces like natural and sexual selection have contributed to diversification within the species and that these processes might result in the formation of new species. These evolutionary processes involved in speciation need more attention in conservation planning.
