Stand structural attributes and functional trait composition overrule the effects of functional divergence on aboveground biomass during Amazon forest succession

Mass‐ratio and complementarity effects simultaneously drive aboveground biomass in temperate Quercus forests through stand structure

“…Therefore, the mass-ratio effect was more important than that of the complementarity effect (Figure 4b). This is consistent with previous multiple studies showing that biomass storage can be better explained by mass-ratio effect than by the complementarity effect (Chiang et al, 2016;Prado-Junior et al, 2016;Villa et al, 2020). Fotis et al (2018) also found that the AGB was driven by mass-ratio effects in a temperate deciduous forest.…”

Structural diversity consistently mediates species richness effects on aboveground carbon along altitudinal gradients in northern Ethiopian grazing exclosures

“…However, we observed a weak mediation effect of functional composition, i.e., CWM MAXH across altitudinal zones only. Consistent with other studies across a range of forest types Aponte et al, 2020;Mensah et al, 2021;Villa et al, 2020), this finding provides support to the mass ratio hypothesis and indicates that the selection effect also drives carbon storage in the exclosures. In particular, the negative influence of species richness on CWM MAXH suggests that a few dominant and productive species contribute to higher AGC due to the competitive exclusion effect (Ali et al, 2016;Mensah et al, 2016).…”

“…That the selection effect operated at the broad environmental scale only stresses the scale-dependency of the biotic mechanisms driving diversity-carbon relationships and reflects the importance of the scale in the analyses of biodiversity effects (e.g., Chisholm et al, 2013). Overall, the effect of structural diversity was stronger than that of functional composition and both structural diversity and functional composition overruled the effect of functional diversity on AGC in the exclosures, as recently reported by Villa et al (2020).…”

Forest disturbance and recovery in Peruvian Amazonia

“…These results were expected, as surrounding forests foster natural regeneration processes by acting as a source of propagules, necessary for tree recruitment (Chazdon, 2003; Rocha et al, 2016). Moreover, though not explored here, biotic factors such as species and functional diversity have been found to influence AGB to a lesser extent in regrowing forests (Capellesso et al, 2020; Manuel Villa et al, 2020; Pyles et al, 2018).…”
