Current Research
Poison or Passion: warning and attraction in a color polymorphic frog
I study color divergence in the poison frog Oophaga pumilio. This small Dendrobatid frog (~2 cm) is colored red and blue throughout most of its range, from Nicaragua to Panama. But in the Bocas del Toro Archipelago in western Panama, the species shows extreme color variation among populations, ranging from orange to yellow to blue, sometimes with black spots or stripes. I investigate the roles of natural and sexual selection in explaining this color diversity. Specifically, I look at interpopulation variation in predator communities and female preferences. Fieldwork for this project is hosted by the Bocas Field Station of the Smithsonian Tropical Research Institute. Funding comes from a ‘Rubicon’ grant awarded by the Netherlands Science Foundation (NWO).
Oophaga pumilio color morphs from the Bocas del Toro region: mainland (near Almirante), Isla Pastores, Isla Popa (north side), Aguacate Peninsula, Isla Colón, Isla Bastimentos, Isla Popa (south side).
