Nitrogen Cycling Key to Invasive Species
(Image 2)
Researchers from the University of Nebraska-Lincoln (UNL) examine experimental plots containing different plant species. The plots have a white planter pot buried in the center with an access hole to the bottom to capture all water and dissolved nutrients leaving the pot. Their study, supported in part by the National Science Foundation, found important new information on how plants can change nitrogen cycling in order to gain nitrogen, and how this allows nonnative plant species to invade and take over native plants. To learn more, see the UNL news release "Knops' research on invasive species shows nitrogen cycling is key." (Date of Image: June 2005) [See related image Here.]
