Coefficient table from regression of number of consumer species and ecosystem functions

Function m SE t P R2 Dmax
Decomposition, g/mo 0.87 0.19 4.67 <0.0001 0.26 0.292
NPP, g/m2 −19.7 20.11 −0.98 0.3305 0.0153 −0.364

Multifunctionality, % 0.10 0.02 4.11 0.0003 0.534 0.270

Significant P and R2 values (at an α level of 0.05) are bolded. Dmax > 0 indicates that overyielding contributes to the effect of diversity on functioning.
