Invasibility of a mesic grassland depends on the time‐scale of fluctuating resources

Summary Global change is increasing the frequency and magnitude of resource fluctuations (pulses) at multiple time‐scales. According to the fluctuating resource availability hypothesis ( FRAH ), susceptibility of an ecosystem to invasion (i.e. invasibility) is expected to increase whenever resource supply exceeds that which is utilized by native communities. Thus, global change has the potential to increase invasibility around the world. Here,...
