Dyeing poison frog (Dendrobates tinctorius) fathers drop their young off in pools within tree hollows or fallen logs, where the tadpoles grow up. One of the main dangers to the developing frogs is cannibalism by other tadpoles in the same pool. Despite this risk, males are more likely to deposit their offspring in pools where other tadpoles are already present, according to a study published in Behavioral Ecology and Sociobiology last week (January 20 2014).
Bibiana Rojas of Deakin University first characterized the sites where dyeing poison frog fathers placed their young in French Guinean forests, and found that they often chose pools inhabited by other tadpoles (of the same and different species) and insect larvae. The larger the size difference between old and new residents, the more likely the frog father was to choose a given pool, Rojas found. For more information on Bibiana’s findings CLICK HERE.
