That’s the unexpected takeaway of a recent study by researchers from Sewanee: The University of the South, Southeast Missouri State University and the Tennessee Aquarium. The group’s findings soon will be published in Animal Conservation, a London-based, peer-reviewed scientific journal.

Normally, salamanders live in size-structured communities, meaning larger species tend to out-compete smaller species for prime position in the cooler, deeper waters in the middle of the stream. But research suggests smaller species will adapt more readily to the warmer conditions that climate change is predicted to bring about.
