Briefings

Recent research from the Smithsonian's National Zoo and Conservation Biology Institute and Pennsylvania State University identifies amphibian chytridiomycosis as the likely cause of frog population declines in Brazil's Atlantic Forest since the 1970s. Published in Molecular Ecology, this study connects historical disease patterns to modern extinction events, offering a potential solution for conservation efforts.

Key points

• Scientists at the Smithsonian's National Zoo and Conservation Biology Institute and Pennsylvania State University identified amphibian chytridiomycosis as the likely cause of frog declines in Brazil's Atlantic Forest since the 1970s.
• The study, published in Molecular Ecology, links historical disease patterns to modern extinction events, suggesting a potential solution for conservation efforts.

Context and limitations

The evidence is limited to a single study published in 2026, which may not represent the full scope of the disease's impact or all contributing factors to amphibian declines in the Atlantic Forest.
