Geographic assessment of the response of three different endemic Puerto Rican anurans to the pathogenic fungus Batrachochytrium dendrobatidis (Bd)


Chytridiomycosis is a lethal infectious disease caused by the pathogenic chytrid fungus Batrachochytrium dendrobatidis (Bd), which is responsible for the extinction of many amphibians worldwide. In Puerto Rico three species of Eleutherodactylus disappeared potentially due to this pathogen, and many others are at risk. A synergistic effect between Bd and climate was shown for two species at El Yunque, but this relationship has not been tested in other species or forests. The purpose of this study is to evaluate the status of Bd in three endemic species, Eleutherodactylus wightmanae, Eleutherodactylus coqui, and Leptodactylus albilabris, which differ in conservation status, ecology and life history, in three highland forests across the island. Results from this study will enhance our understanding of the mechanisms of Bd under enzootic conditions.

Her advisor is Dr. Patricia Burrowes, who also co-authored our biodiversity and frog study paper.
