Relationship between community stability, defined as the inverse of the coefficient of variation (CV) in above-ground biomass indexed by point-frame pin hits per 0.25 m² plot across the past 7 years of the experiment, and community diversity, according to GLM-derived means of treatment plots. Community diversity is defined as the total number of species of deciduous shrubs and forbs plus the number of additional functional groups per 0.25 m² plot. E, exclosed; G, grazed; W, warmed; A, ambient. Because analyses were performed on the CV of biomass, indexed by point-frame sampling, rather than on the inverse of the CV, the y-axis is reversed to illustrate increasing stability (i.e. smaller CV values) upwards along the axis. Error bars represent ±1 s.e.
