Like birds, plants can migrate in response to temperature change, though much more slowly. By producing seeds, a tree can march toward a newer home by a few meters each year. A team of scientists from the Appalachian Laboratory are working to find and sequence DNA held within the ancient pollen of trees and compare it with what they find in the same species rooted on today's landscape to draw better conclusions about how trees may respond to ongoing and future climate changes.
"We're hoping that some of the things we learn from this particular species can inform our understanding of how other tree species will or won't adapt or respond to climate change," said Dave Nelson.
