Extended Data Fig. 9: Impacts of human pressures on local diversity estimated from experimental studies using weighted regression.

Log-response ratio of local diversity (logarithm-transformed ratio of impacted to reference values, LRR local diversity). The global response (all data) shown on the first row is separated by factors in the following rows. The numbers between parentheses indicate the number of comparisons. For each category the dot represents the marginal mean computed from the model; dot size is proportional to number of studies included. The larger bar shows the 95% confidence interval and the thinner bar represents the 99% confidence interval. The weighting scheme applied is the inverse of the variance of the effect size, computed following Hedges et al.⁶².
