New work published in the journal Nature Ecology & Evolution by an  international team of researchers including Dr. Gui Becker shows how ambibian skin microbiomes – the bacteria and other microrganisms living on frogs and their relatives – are distributed globally. The team examined climate and geographic data to understand their effects on the microbiome on a global scale. Results of this work show that amphibian microbiomes fluctuate with seasons. Further, they did not find a core microbiome for species that live across different climatic zones. The common bullfrog, for example, had a different microbiome in North America than in South America. This work has important implications for amphibian conservation.
