Appendix C. Output for GLMM analyses testing for effects of trophic rank, dispersal ability, and body size on SAR.

Table C1. Model output for the fixed effects parameters of the generalized linear mixed models testing for effects of trophic rank, dispersal ability and body size on species richness within the group of typical dry grassland carabid beetles. Significant effects are marked: * p ≤ 0.05, ** p ≤ 0.01.
