One-way ANCOVA comparing the slopes and intercepts of regressions (between FD and community richness after the removal of 7, 15, 22 and 29 species) when species were removed by selecting only exploited versus randomly (E vs. R) from the regional species pool. All terms tested against the residual. Table shows only F-values and significance values as * P<0.05, ** P<0.01, and *** P<0.001.
