Scientists Send Conservationists Back to the Drawing Board

Talk about imperfect science. Researchers recently discovered that the fish being used to replenish stocks of endangered greenback cutthroat in the U.S. west were in fact a different species, the Colorado cutthroat. According to this piece in Conservation magazine, the mistake may mean that greenbacks are even more endangered than before.
Meanwhile, you may remember that a few years ago California’s Department of Fish and Game suspended planting high country waters with hatchery-reared trout, believing the trout were responsible for the decline in red-legged and yellow-legged frogs. Now scientists at two California universities believe that a fungus is the actual culprit.
