Department of Biological Sciences' Christine Parent, Andrew Kraemer, and BCB student Andrew Rankin published a paper on Galápagos snails in the Proceedings of The Royal Society B. They found mockingbirds were less likely to feed on snails that matched the color of their backgrounds than conspicuous snails. They think this food selection process may have led to the variation in snail color across the island chain. In addition, it seems the snails in the sunniest locations have evolved to reflect more light than shade-dwelling snails, an adaptation that would help them avoid overheating.
