CU-Boulder amphibian study shows how biodiversity can protect against disease
Date:2/13/2013

ease in the biodiversity of the bird population. Birds act as "reservoir hosts" for West Nile virus, harboring the pathogen indefinitely with no ill effects and passing the pathogen onto mosquitoes.

"Our results indicate that higher diversity reduces the success of pathogens in moving between hosts," Johnson said. "Nonetheless, if infection pressure is high, for instance in a year with high abundance of vectors, there will still be a significant risk of disease; biodiversity will simply function to dampen transmission success."
