Global warming and amphibian losses; The proximate cause of frog declines? (Reply)

Abstract

Alford et al.1 question the working model underlying our test2 for a link between global warming and amphibian disappearances, and Di Rosa et al.3 criticize our emphasis on a single proximate agent, the chytrid fungus Batrachochytrium dendrobatidis. Both teams report key pieces of the amphibian-decline puzzle and new evidence from different parts of the world that climate change is a factor in these losses. Here we show why our working model was appropriate and highlight the complexity of the imminent threat to species survival that results as global warming conspires with various other agents.
