Environmental filtering, predominance of strong competitor trees and exclusion of moderate-weak competitor trees shape species richness and biomass.

Strong competitor (i.e. big-sized) trees are globally crucial for promoting aboveground biomass.

Impacts of climatic and edaphic factors on the diversity, structure and biomass of species-poor and structurally-complex forests.

Understanding the impacts of multiple climatic and edaphic factors on forest diversity, structure and biomass is crucial to predicting how forests will react to global environmental change. Here, we addressed how do forest structural attributes (i.e.
