Correction to: Weather modifies the spatial extent of carbohydrate transfers from CO 2 -supplied broad-leaved trees to ectomycorrhizal fungi

Weather conditions and fungal morphology may influence spatial and temporal dynamics of carbon transfer to ectomycorrhizal fungi from their tree hosts but field studies of these dynamics are challenging. Broad-leaved trees in a Swiss forest were labeled with 13C-depleted CO2 from 2001–2005 and 13C traced into ectomycorrhizal sporocarps collected at different distances from those trees. We then correlated distance (zone), year, fungal genus, fungal morphology, and solar radiation against sporocarp δ13C and loge C/N in stepwise regressions. CO2-supplied trees contributed 71 ± 5
