New greenhouse experiment:

Plant-soil feedback effets of the invasive Elymus caput-medusahead depending on its density. Feedbacks on its own growth and on the dominant species Avena Fatua. Soils collected in the field in 35 plots along a density gradient ranging from 0 to 1800 individuals of E. caput-medusahead. Thanks to the Undergrads who are helping managing this experiment.
