New paper on frog skin bacteria
Our paper on frog skin bacteria along the Amazon-Andes elevational transect (500 - 3800 m a.s.l.) was published today in Frontiers in Microbiology. We found lower numbers of anti-Bd isolates at elevations where amphibian declines had been greatest, and high proportion of anti-Bd isolates of high inhibitory strength in Bd-resistant frogs, supporting the idea that symbiotic bacteria play a functional role in amphibian skin defense. Yet this association does not consistently explain the fate of amphibian hosts along the elevational gradient, suggesting complex interactions among bacterial symbionts, hosts, and environmental factors in determining frog persistence in a region of high disease prevalence.
