The massive trees of the south give way to nearly treeless tundra in the far north. But despite being separated by over 1,000 kilometers, both places had something in common: climate change was beginning to impact the…

Although lawns may start out as monocultures of Kentucky Bluegrass (Poa pratensis), they never stay that way.
