AI Insight
UCLA biologists have discovered that the Batrachochytrium dendrobatidis (Bd) fungus, which is causing severe population declines in amphibians worldwide, resides in Yosemite toad burrows rather than exclusively in aquatic environments as previously believed. This finding challenges the long-held assumption that toads are primarily infected through water contact via their permeable skin. The discovery reveals that the toads may be carrying the deadly pathogen in their own terrestrial shelters.
Why it matters
This discovery could fundamentally change conservation strategies for threatened amphibian species, as protective measures have focused primarily on aquatic habitats. Understanding that the fungus persists in burrows may lead to new approaches for controlling Bd spread and protecting vulnerable toad populations.
Understand the Science
UCLA biologists have found the hiding place of a silent killer stalking threatened Yosemite toads: their own burrows. The Batrachochytrium dendrobatidis (Bd) fungus decimating amphibian populations around the world has long been thought to live in and infect the toads through their skin when they are in the water.
