Fig. 5

Response of understorey richness vs. response of understorey abundance to ungulate herbivory. Each symbol represents a set of study plots from which data were reported on both richness and abundance. For calculation of the regression, data were weighted based on sample size (as indicated by the sizes of symbols). The outlier at the bottom is one of several data points from Pekin et al. [52] (low vs. zero cattle density at unburned sites; n = 2). If it is excluded, R² increases to 0.32
