'McDonalization' of frogs
Date:9/22/2009

But the primarily aquatic fungus killed most of the water-loving species.

"Now the frog communities are typified by terrestrial species," says Smith, "which has changed the whole way the system works ecologically."

"Our results suggest that the slate of ecological history in these assemblages has been partially erased and that the communities that remain consist primarily of species that are resistant to the fungus."

Smith called the fungus an "extinction filter." Not an equal-opportunity killer, it preferentially removes the frogs that make each habitat unusual and interesting. Maybe it should be called a boredom filter instead.
