What's New:

Lab member Caroline Curtis has been awarded a NASA Earth System Science Fellowship to study non-native pine invasion in South America using satellite imagery. Congratulations, Caroline!

Our new paper compares the spatial distributions of invasive vs. native plants across the US. Although we commonly think of invaders as starting at one unlucky spot and moving outward, our research found that invasive plants are incredibly widespread - even the relatively rare ones. In contrast, native plants do not receive the advantage of widespread human introduction. We're actively assisting the migration of invasives and leaving behind the natives.

About the spatial ecology lab

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.
