  • These are the required data to do all subsequent analyses in Avolio et al. 2021 in Ecology Letters using the Community Responses to Resource Experiments database (corredata.weebly.com). Paper abstract: Global change is impacting plant community composition, but the mechanisms underlying these changes are unclear. Using a dataset of 58 global change experiments, we tested the five fundamental mechanisms of community change: changes in evenness and richness, re-ordering, species gains and losses. We found 71% communities were impacted by global change treatments, and 88% of communities that were exposed to two or more global change drivers were impacted. Further, all mechanisms of change were equally likely to be affected by global change treatments – species losses and changes in richness were just as common as species gains and re-ordering. We also found no evidence of a progression of community changes, e.g., re-ordering and changes in evenness did not precede species gains and losses. We demonstrate that all processes underlying plant community composition changes are equally affected by treatments and often occur simultaneously, necessitating a wholistic approach to quantifying community changes.
