| Summary | The presence of a relatively contiguous range of reproductive modes within the Dendrobatidae allows for experimental testing of the ecological factors that drive reproductive strategy in the lineage. Changes in body size, size and number of offspring, reproductive mode and larval habitat were examined within a phylogenetic framework to examine the relationship between phytotelmata use and other life history traits. The larval placement strategy of Allobates femoralis was tested in Southeastern Peru using a blocked, fully crossed experimental design. Further experiments investigated the community diversity of Allobates breeding sites and the colonization of insect predators. Results suggest that predation by aquatic insects influences larval placement in Allobates. Similar ecological interactions may have driven toxic dendrobatids to the use of arboreal phytotelmata and associated derived reproductive strategies. |
