Large trees drive forest aboveground biomass variation in moist lowland forests across the tropics
Aim Large trees (d.b.h. 70 cm) store large amounts of biomass. Several studies suggest that large trees may be vulnerable to changing climate, poten- tially leading to declining forest biomass…

The results indicate that AGB is mediated by both climate and soils, and suggest that the AGB of African closed-canopy tropical forests may be particularly sensitive to future precipitation and temperature changes.
Tree allometry in Central Africa: Testing the validity of pantropical multi-species allometric equations for estimating biomass and carbon stocks
Diversity and carbon storage across the tropical forest biome
A unique pan-tropical dataset of 360 plots located in structurally intact old-growth closed-canopy forest is compiled, surveyed using standardised methods, allowing a multi-scale evaluation of diversity-carbon relationships in tropical forests.
Will Elephants Soon Disappear from West African Savannahs?
Precipitous declines in Africa's native fauna and flora are recognized, but few comprehensive records of these changes have been compiled. Here, we present population trends for African elephants in…
Asynchronous carbon sink saturation in African and Amazonian tropical forests
Overall, the uptake of carbon into Earth’s intact tropical forests peaked in the 1990s and independent observations indicating greater recent carbon uptake into the Northern Hemisphere landmass reinforce the conclusion that the intact tropical forest carbon sink has already peaked.
Globally, functional traits are weak predictors of juvenile tree growth, and we do not know why
It is concluded that the most widely studied functional traits in plant ecology were poor predictors of tree growth over large scales and may be unsuitable for predicting growth of trees over broad scales.

Few dominant species made the greatest contribution to the AGB and the importance of preserving G. dewevrei forest in the context of ‘Reducing Emissions from Deforestation and forest Degradation’ (REDD) policies is discussed.
Geological Substrates Shape Tree Species and Trait Distributions in African Moist Forests
The results indicate strong environmental filtering due to differential soil resource availability across geological substrates and long-term human disturbances in resource-rich areas may have accentuated the observed patterns of species and trait distributions.
Seeing Central African forests through their largest trees
It is shown that the above-ground biomass (AGB) of the whole forest can be predicted from a few large trees and that the relationship is proved strikingly stable in 175 1-ha plots investigated across 8 sites spanning Central Africa.
