Species-rich amphibian communities better able to fend off parasitic infections
In the frog pond, more species means better health for all. More diverse amphibian communities are less likely to transmit a virulent parasite that causes limb deformities in frogs, researchers report in the Feb. 14 Nature.
Pieter Johnson of the University of Colorado Boulder and colleagues used field data from hundreds of California ponds to show that susceptible species dominate in less diverse amphibian communities. In communities that are more diverse, more resistant species move in.
Communities with high species diversity had nearly 80 percent less transmission of the tre
