Road Runoff Spurring Spotted Salamander Evolution
2012-02-02 05:00:31

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. Salamanders breeding in roadside ponds are exposed to a host of contaminants from road runoff. Chief among these is sodium chloride from road salt, which reaches average concentrations of 70 times...
