  abstract = {{W}ood density ({WD}) relates to important tree functions such as stem mechanics and resistance against pathogens. {T}his functional trait can exhibit high intraindividual variability both radially and vertically. {W}ith the rise of {L}i{DAR}-based methodologies allowing nondestructive tree volume estimations, failing to account for {WD} variations related to tree function and biomass investment strategies may lead to large systematic bias in {AGB} estimations. {H}ere, we use a unique destructive dataset from 822 trees belonging to 51 phylogenetically dispersed tree species harvested across forest types in {C}entral {A}frica to determine vertical gradients in {WD} from the stump to the branch tips, how these gradients relate to regeneration guilds and their implications for {AGB} estimations. {W}e find that decreasing {WD} from the tree base to the branch tips is characteristic of shade-tolerant species, while light-demanding and pioneer species exhibit stationary or increasing vertical trends. {A}cross all species, the {WD} range is narrower in tree crowns than at the tree base, reflecting more similar physiological and mechanical constraints in the canopy. {V}ertical gradients in {WD} induce significant bias (10%) in {AGB} estimates when using database-derived species-average {WD} data. {H}owever, the correlation between the vertical gradients and basal {WD} allows the derivation of general correction models. {W}ith the ongoing development of remote sensing products providing 3{D} information for entire trees and forest stands, our findings indicate promising ways to improve greenhouse gas accounting in tropical countries and advance our understanding of adaptive strategies allowing trees to grow and survive in dense rainforests.},
