Biomass production (net primary production – NPP) and net ecosystem exchange (NEE) are subject to respiration and other carbon losses, which vary with local conditions and life history traits. Here, the authors use a simulation approach to study how these losses impact forest productivity and reveal themselves in forest structure. The authors fit the process-based forest model FORMIND to a 25 ha inventory of an old-growth temperate forest in China and classify trees as “mature” (fully grown) or “immature” based on their intrinsic carbon use efficiency.
