Abstract Considerable attention has been directed to studying the infection dynamics of the fungal pathogen, Batrachochytrium dendrobatidis (Bd), affecting amphibians in the high elevations of the Neotropics. Lowland forests of the same realm, on the other hand, remain relatively understudied in this context. Herein, an attempt to bridge this gap was made by investigating the occurrence of Bd in several anuran taxa inhabiting the Amazonian lowlands in the northeast of Ecuador.
