Structural heterogeneity modulates the effects of stem density on standing biomass in mature dry Isoberlinia woodlands

open access: yesFrontiers in Forests and Global Change
IntroductionWhile the impacts of forest structural attributes on above-ground biomass (AGB) has been largely documented in closed-canopy forests, much less is known in dry forests, where water rather than light drives biomass accumulation. In particular,
