Our research in Costa Rica, Central America, occurs primarily on the Pacific side of the country in the Osa Region. We are interested in the conservation and management of wildlife in both undeveloped areas and those undergoing rapid change. Our wildlife research primarily focuses on reptile species, with emphases on crocodilians and sea turtles, and how habitat and environmental quality influence their health and behaviors. We partner with researchers and educators throughout the country, but our primary research efforts are through our recently established organization, Osa Ecology, co-founded by Phoebe Edge (Director) and Kimberly Andrews. Osa Ecology works primarily on the beaches and mangrove habitats around Golfo Dulce on the southern Osa Peninsula. Initially, our efforts are concentrated on monitoring the American crocodiles (Crocodylus acutus), spectacled caiman (Caiman crocodilus), and four species of sea turtles that inhabit these marine and aquatic habitats, but our research is also expanding to include snakes and a collaborative effort focused on whales and dolphins in the Gulf. We also conduct research with Reserva Playa Tortuga (Oscar Brenes, Director). There, our program includes a population study on the two crocodilian species in the Térraba River and the spatial ecology and habitat use patterns of adult American crocodiles. Additionally, we monitor erosional patterns along beach shorelines in order to understand how habitat quality and availability influence nesting success of olive ridley (Lepidochelys olivacea) and green (Chelonia mydas) sea turtle populations.
