Are distribution data the best way to model invasion risk? In a new paper in Biological Invasions, we argue that abundance is a better proxy for invasive plant impact and show that distribution data vastly overestimate locations where invasive plants could become abundant.
Spatial ecology uses geographic patterns of species across landscapes and regions to uncover patterns that help us understand what influences distribution. We focus primarily on non-native invasive plants, with a goal of better understanding the biogeography of invasion risk. Our research investigates how global change interacts with species invasion to affect native ecosystems. The above image highlights potential shifts in kudzu distribution with temperature warming.
