Amphibians in losing race with environmental change

ecies lay their eggs communally or congregate socially, often to avoid predation or improve resource use. But global warming has caused higher levels of certain infectious diseases of some amphibians, and it spreads more easily in closely connected communities.

"Although relatively rapid evolution may occur within some amphibian populations when a novel threat arises, other threats may be too intense and too new for amphibians to cope with them," the researchers wrote in their report. "Behaviors and ecological attributes that have probably persisted, and were probably beneficial, for millions of years . . . under today's conditions may subject amphibians to a variety of damaging agents."

Natural selection and species adaptation may, in time, allow amphibians to react to and recover from the new environmental insults, Blaustein said, if they don't go extinct first.

But evolution is an erratic, often slow and imperfect system, and the complexities of amphibian life cycles makes them more immediately vulnerable than many other species, the researchers said.
