Appalachian salamanders have gotten shorter in the past 50 years, possibly adapting to warmer, drier weather conditions, according to a report in Global Change Biology. Researchers at the University of Maryland compared specimens they collected with those collected by museums from the same areas since 1957. They found that each generation of salamanders in several species grew 1% smaller and that the highest incidence of shrinkage occurred in areas where temperatures rose and rainfall dropped the most.
