Co-occurring invasive plant interactions do not predict the impacts of invasion in experimental tallgrass prairie communities

Co-occurring invasive plants are an understudied yet common phenomenon, and likely to become even more frequent with climate change-driven range shifts. Invasive–invasive interactions can be competitive, neutral, or facilitative; symmetric or asymmetric; and their impact on natives can be additive or non-additive. Non-additive impacts, wherein co-occurring invasives either reduce or enhance one another’s effects, have heightened implications for...
