<b>Resource availability enhances </b><b>po</b><b>sitive tree diversity effects on carbon and nitrogen accrual in natural forests</b>

By analysing Canada’s National Forest Inventory database, this article presents, for the first time, continental-scale evidence that the effects of tree diversity on decadal accumulation of C and N in tree biomass and forest soils is strongly dependent on resource availability and non-resource related stress gradients
