Frog Pile (IMAGE)
Caption
A pile of southern mountain yellow-legged frogs in California's Sierra Nevada, where San Francisco State University Professor Vance Vredenburg and colleagues tracked the spread of the deadly amphibian disease Chytridiomycosis during a 13-year period. New research by Vredenburg and colleagues, published in PNAS, suggests that high population densities in frog communities could promote re-infection among frogs, causing the intensity of the disease to reach dangerously high levels. Reducing population density could be a way to limit infection intensity and allow some frogs to survive a Chytridiomycosis epidemic.
