摘要
Aim It is increasingly accepted that the mean wood density of trees within a 森林 is tightly coupled to above-ground 森林 biomass. It is unknown, however, if a positive relationship between 森林 biomass and mean community wood density is a general phenomenon across 森林s. Understanding spatial variation in biomass as a function of wood density both within and among 森林s is important for predicting changes in stored carbon in response to global change, and here we evaluated the generality of a positive biomass-wood density relationship within and among six tropical 森林s. Location Costa Rica, Panama, Puerto Rico and Ecuador. Methods Individual stem data, including diameter at breast height and spatial position, for six 森林 dynamics plots were merged with an extensive wood density database. Individual s
