The Great Lakes Radio Consortium posted this story about the recovery of the endangered Lake Erie water snake (Nerodia sipedon insularum). Researchers have found that invasive round gobies (Neogobius melanostomus) inhabiting in the lake have had a somewhat surprising impact on the aquatic reptiles. The snakes are rounded up at a yearly "Nerodeo" where scientists take measurements and check stomach contents. While the snakes' meals consisted mainly of native species of fish and amphibians during the 1980s and 1990s, today that has changed radically: their diet is now 90% round goby. The snakes are apparently better off for it too, growing faster than before on a prey that is currently quite abundant. Be sure to click on the "Listen" link to hear the full audio report.
