The Eco-Immunology of Disease Resistance in Amphibians

Quick fact

Amphibians can mount different immune responses depending on temperature, with cooler temperatures slowing immune function and increasing susceptibility to chytrid fungus, a major driver of global amphibian declines.

Why this is interesting

You might think a frog's immune system is always ready to fight disease, but in the wild, its defenses depend on the environment. Why do some frog populations resist a deadly fungus while others are wiped out?
