Abstract	:	Forests play a central role in global biogeochemical cycling by storing carbon (C) and retaining nutrients. Yet, we have limited understanding of how shifts in forest composition (owing to global environmental changes) will affect ecosystem functioning. A long history of research demonstrates that ecosystem consequences of species shifts are largely a function of two factors: the dominant species’ functional traits, and the degree to which species’ traits interact with biogeochemical variation across the landscape. Still, at least two critical knowledge gaps remain. First, research to date has primarily focused on aboveground plant traits, with far less known about the importance of species’ variation in root traits (key drivers of C-nutrient coupling belowground) or the degree to which root traits are coordinated with aboveground traits. Second, while several existing frameworks have been used to group plant species based on their functional attributes, there has been little integration of these frameworks into a unified conceptual model for predicting ecosystem consequences of species shifts.
