Diversity aided mammals' survival over deep time
Lawrence LeBlond for RedOrbit.com In a first of its kind study, researchers from Vanderbilt University found that mammals' best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes. Larisa R. G. DeSantis, Assistant Professor of Earth and Environmental Sciences at Vanderbilt, led researchers in studying how North American mammals adapted to climate change over a 56-million-year period, beginning with the Eocene and ending with the Pleistocene extinction 12,000 years ago, when the continent's megafauna (mammoths, saber-tooth tigers, giant sloths, etc) vanished. DeSantis noted that it was important to first understand how mammals responded to climate change in the deep past, before predicting how they will respond to future climate change. "It is particularly important to establish a baseline that shows how they adapted before humans came on the scene to complicate the picture," she said. An established baselin
When it comes to adapting to climate change, diversity is the mammal's best defense.
