Figure 3. Stable isotope values of Collembola and Oribatida in two farming systems.
Mean (±95% confidence interval) Δ13C (upper panel) and Δ15N values (lower panel) of two oribatid mite (Scheloribates laevigatus, Tectocepheus sarekensis) and four Collembola species (Isotoma caerulea, Isotomurus maculatus, Orchesella villosa, Mesaphorura sp.) in conventional (conv) and organic (org) farming systems; note that for Mesaphorura sp. only Δ13C values are shown. For statistical analysis see Table 3.
