Climate warming can slow how tree roots feed soil microbes
A plant's roots do much of their work out of sight, pulling in water and nutrients and holding the plant in place. That makes it hard to see how plants respond when conditions underground change, and how a warming climate affects them. New Dartmouth-led studies look at the strate
