Densities of root‐feeding (a), bacterivorous (b), omnivorous (c), fungivorous (d), and nematodes in soil (N/100 g dry soil) in mesocosms with native plant species (NAT; white), related range expanders (RRE; light grey), and unrelated range expanders (URE; dark grey) in soils from the original range (south) and the new range (north) of the range expanders. Bars represent averages ± standard errors. Horizontal bars and asterisks indicate significant differences between soil origins and different letters indicate significant (p < 0.05) differences between plant communities within ranges based on negative binomial GLM and post hoc Wald tests
