Increasing carbon storage in intact African tropical forests

Taxon-specific analyses of African inventory and other data suggest that widespread changes in resource availability, such as increasing atmospheric carbon dioxide concentrations, may be the cause of the increase in carbon stocks, as some theory and models predict.
The impact of land conversion on plant biodiversity in the forest zone of Cameroon

Floristic surveys were carried out in different land use systems(primary and secondary forest, fallows of different ages, cocoa plantations,crop fields) within the forest zone of Cameroon, to assess…
Height-diameter allometry of tropical forest trees
- T. Feldpausch, L. Banin, J. Lloyd

- 25 October 2010
Abstract. Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in…
Above-ground biomass and structure of 260 African tropical forests

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.
Positive biodiversity-productivity relationship predominant in global forests

A consistent positive concave-down effect of biodiversity on forest productivity across the world is revealed, showing that a continued biodiversity loss would result in an accelerating decline in forest productivity worldwide.
Drought-mortality relationships for tropical forests.

It is indicated that repeated droughts would shift the functional composition of tropical forests toward smaller, denser-wooded trees, suggesting the existence of moisture stress thresholds beyond which some tropical forests would suffer catastrophic tree mortality.
Tree height integrated into pantropical forest biomass estimates
- T. Feldpausch, J. Lloyd, O. Phillips
- Environmental Science
- 27 August 2012
Abstract. Aboveground tropical tree biomass and carbon storage estimates commonly ignore tree height (H). We estimate the effect of incorporating H on tropics-wide forest biomass estimates in 327…
Tropical forest tree mortality, recruitment and turnover rates: calculation, interpretation and comparison when census intervals vary
- S. Lewis, O. Phillips, R. Vásquez Martínez
- Environmental Science
- 1 December 2004
1 Mathematical proofs show that rate estimates, for example of mortality and recruitment, will decrease with increasing census interval when obtained from censuses of non‐homogeneous populations.…
Asynchronous carbon sink saturation in African and Amazonian tropical forests
- W. Hubau, S. Lewis, L. Zemagho
- Environmental ScienceNature
- 1 March 2020
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.
Allometric equations for integrating remote sensing imagery into forest monitoring programmes

- 6 July 2016
A global database of 108753 trees for which stem diameter, height and crown diameter have all been measured is compiled and it is found that a single equation predicts stem diameter from these two variables across the world's forests.
