This study examines the effects of tree species diversity on ecosystem multifunctionality in subtropical forests. The study finds that tree height functional diversity is the best predictor of multifunctionality, and functional diversity has a stronger impact on multifunctionality compared to species richness and fungal diversity. Stand structure plays a crucial role in modulating the effects of tree diversity on multifunctionality. The findings suggest that selecting appropriate species composition and maximizing forest structural complexity are effective strategies to enhance forest multifunctionality while conserving biodiversity under global environmental changes.
Tree species diversity is assumed to be an important component in managing forest ecosystems because of effects on multiple functions or ecosystem multifunctionality. However, the importance of tree diversity in determining multifunctionality in structurally complex subtropical forests relative to other regulators (e.g., soil microbial diversity, stand structure, and environmental conditions) remains uncertain. In this study, effects of aboveground (species richness and functional and structural diversity) and belowground (bacterial and fungal diversity) biodiversity, functional composition (community-weighted means of species traits), stand structure (diameter at breast height and stand density), and soil factors (pH and bulk density) on multifunctionality (including biomass production, carbon stock, and nutrient cycling) were examined along a tree diversity gradient in subtropical forests. The community-weighted mean of tree maximum height was the best predictor of ecosystem multifunctionality. Functional diversity explained a higher proportion of the variation in multifunctionality than that of species richness and fungal diversity. Stand structure -played an important role in modulating the effects of tree diversity on multifunctionality. The work highlights that species composition and maximizing forest structural complexity are effective strategies to increase forest multifunctionality while also conserving biodiversity in the management of multifunctional forests under global environmental changes.
