The fast invader dominated under normal precipitation conditions.
The slow native won when precipitation declined.
While our approach requires replication across more species, our findings suggest that life history theory may help predict which plant species, including exotics versus natives, will excel under future climate scenarios.
In plant communities where the natives are adapted to stressful conditions, climate-driven shifts toward more stressful conditions can favor natives over exotic plant invaders.
