Developing a macroecological understanding of invasive plant impacts based on abundance and trait data

Understanding invasive plant impacts can provide insight into community assembly and inform the development of successful management strategies. The impacts of invasive species depend on how they alter patterns of abundance within recipient communities and on the characteristics of the invaders and the affected species. Research has suggested that common species may be more impacted by invasions, and that similarity between native and invasive species underlies impact. To assess large-scale patterns of invasive plant impact, we are bringing together plant community data from 75,000 plots across natural areas of the U.S. with information on plant functional traits and evolutionary history. Functional traits are characteristics of an [...]
