Cascading impacts of prey loss

The global pandemic caused by the amphibian fungal pathogen Batrachochytrium dendrobatidis has decimated frog populations around the world. This decline has been called out as a potential catastrophe for amphibian species. What has been less explored are the impacts of amphibian declines on other members of their ecological communities. Using survey data collected over 13 years, Zipkin et al. looked at diversity and body condition of a tropical snake community after amphibians were decimated by chytridiomycosis. They found that the snake community was less diverse and most species were in decline, except for a few “winning” species.
