Table 2. Comparison of the magnitude of FD loss and regional species richness.

Source Df MS F P
Regional richness (RR) 1 4.89×10−2 30.01 <0.01
Level of removal (LR) 3 5.57×10−3 3.42 <0.05
RR × LR 3 7.15×10−3 4.39 <0.05
Residual 92 1.63×10−3

One-way ANCOVA comparing the magnitude of the ratio between FD random and FD exploited for different levels of species removals (7, 15, 22 and 29 species removals) as a function of regional species richness (logged). All terms tested against the residual.
