Abstract. Plant functional traits determine vegetation responses to environmental variation, but variation in trait values is large, even within a single site. Likewise, uncertainty how these map Earth system feedbacks large. We use demographic model (VDM), the Functionally Assembled Terrestrial Ecosystem Simulator (FATES), explore parameter sensitivity of predictions, and comparison observations, at tropical forest site: Barro Colorado Island Panama. define 12-dimensional distribution plant...

Summary Despite its importance for determining global carbon fluxes, leaf respiration remains poorly constrained in land surface models (LSMs). We tested the sensitivity of Energy Exascale Earth System Model Land – Functionally Assembled Terrestrial Ecosystem Simulator (ELM‐FATES) to variation canopy gradients maintenance ( R dark ). ran and point simulations varying gradient explore impacts on forest structure, composition, cycling. In simulations, steeper lead increased understory survival...

Global continual logging activities have modified the regional landscape and disrupted energy balance through changing surface albedo, evapotranspiration roughness length in both current location (local) nearby areas feedback to atmospheric circulation (non-local). Compared land use change, less attention has been given understanding local biogeophysical effect of different management practices, e.g., wood harvest (logging). Uncertainties from reconstructed global rate forcing data,...
