Determinants of community compositional change are equally affected by global change

Global change is impacting plant community composition, but the mechanisms underlying these changes are unclear. Using a dataset of 58 global experiments, we tested five fundamental change: in evenness and richness, reordering, species gains losses. We found 71% communities were impacted by treatments, 88% that exposed to two or more drivers impacted. Further, all equally likely be affected treatments—species losses richness just as common reordering. also no evidence progression changes, for example, reordering did not precede demonstrate processes composition treatments often occur simultaneously, necessitating wholistic approach quantifying changes.
