Fig. 2From: Conifers and non-native tree species shift trophic niches of generalist arthropod predators in Central European beech forestsBoxplots of a mean isotopic richness (IRic) and b isotopic divergence (IDiv) of ground beetles across stand types. c Mean isotopic uniqueness (IUni) and d isotopic evenness (IEve) of spiders across stand types, divided in northern (light blue) and southern (light red) plots. Significant differences are marked with lower case lettersBack to article page
