In Missouri, about a third of the ponds are infected with chytrid, the notorious skin fungus that has sickened and killed amphibians in other parts of the world. Why only a third, Washington University in St. Louis scientists wondered? A comprehensive study of the the ponds suggests there are hidden constraints on the survival of the fungus. One possibility is that invertebrates present in some ponds but not others allow the fungus to persist by acting as alternative hosts or reservoirs.
Everyone knows that frogs are in trouble. But a recent analysis by Washington University in St. Louis researchers of data on Central American frogs collected by a University of Maryland colleague shows the situation is worse than had been thought.
