not-yet-known not-yet-known not-yet-known unknown Zhang et al. (2025) recently delved deeply into how tree diversity can enhance the yield of woody biomass by promoting cell quantity and cell wall thickness. In this study, researchers found that, compared with monoculture, the average woody biomass yield of all studied species increased by 19-29% at the highest neighborhood species richness (NSR = 4). Neighborhood diversity also leads to changes in the phenology of the cambium.
