Elaeagnus umbellata, soil nitrogen, invasion, facilitation


Invasive species have become an increasing threat to many habitats worldwide. This research addressed the questions of whether several invasive woody plants can germinate, survive and grow in light levels typical of an undisturbed forest understory, and also whether alteration of the nitrogen cycle by one invader is likely to increase the rate of invasion by others.
