Road Runoff Spurring Spotted Salamander Evolution

Feb 1st, 2012 | By

Spotted salamanders exposed to contaminated roadside ponds are adapting to their toxic environments, according to a Yale paper in Scientific Reports. This study provides the first documented evidence that a vertebrate has adapted to the negative effects of roads apparently by evolving rapidly. “This adaptation is certainly encouraging for conservation,” said Steven Brady, the study’s author and a doctoral student at the Yale School of Forestry & Environmental Studies. “But our modern footprint is fundamentally changing species in ways we don’t understand and, critically, we don’t know if these adaptive responses will keep pace with environmental change.”
