3.4 Community weighted means of traits related to biocontrol services
The comparison of community weighted means (CWM) focussed on three species traits related to biocontrol potential of the ants and the old and new grassland habitats. Results for both cereal crop habitats are not shown, due to low cumulative species richness. CWM values of the proportion of animal based resources in ant diet (Fig. 5a) were not significantly different between old and new grasslands (p = 0.285, see Table S8) and analogous results were found for the CWM values of food recruitment strategy (Fig. 5b, p = 0.713) and ant colony size (Fig. 5c, p = 0.992).
