Global Change

Human activities are profoundly changing our biosphere. Land-use changes, climatic change, and biological invasions feed back on societies via their effects on biodiversity and ecosystem services.


We study the impacts of invasive plants and animals in natural and cultivated ecosystems. In addition, we use biological invasions to study basic ecological processes such as competition and dispersal. Changing climate and land-use cause strong dynamics in species interactions and geographic ranges, which we study through experimentation and modeling.
