Nitrogen research shows how some plants invade, take over others

Biologists know that when plants battle for space, often the actual battle is for getting the nitrogen. Now, research at the University of Nebraska-Lincoln gives important new information on how plants can change "nitrogen cycling" to gain nitrogen and how this allows plant species to invade an...

Book on little-known species and conservation provides guidance to managers and others

PORTLAND, Ore. December 21, 2007. In the early 1990s, federal agencies in the West were asked to implement the Northwest Forest Plan.
