TL;DR: The results suggest that xeric grasslands are likely to exhibit the greatest responsiveness of community composition (richness and turnover) to predicted future increases in interannual precipitation variability, which is consistent with the idea that short-lived and less abundant species are more sensitive to interannually climate variability than longer- lived and more abundant species.

TL;DR: The importance of stability mechanisms varied along the environmental gradient: strong negative species covariance occurred in sites characterized by high precipitation variability, whereas portfolio effects increased in sites with high mean annual precipitation.

TL;DR: Because T. x glauca plants were taller when grown with their own litter, it is suggested that this invader may produce positive feedbacks and change the environment in ways that benefit itself and may promote its own invasion.

TL;DR: It is found that resource limitation controlled productivity responses to N enrichment in all systems, and results suggest there may be generality in the mechanisms of plant community change with N enrichment.

TL;DR: It appears that nucleation and, at times, passive restoration may best preserve the diverse legacy of these forested systems (both with lower costs).
