Ecological importance of trees and structure of forest types in the Likouala swamp forest, Republic of Congo Open
Current knowledge, although significant, does not yet provide a full understanding of the functioning of swamp forests in Central Africa. The aim of this study was to estimate the species importance value index (IVI) and characterise the s…

Timing of peat initiation across the central Congo Basin Open
The central Congo Basin contains the world’s most extensive tropical peatland complex, spanning 16.7 million hectares. Until now, radiocarbon dating of basal peats has been limited to 14 samples with poor spatial coverage, and suggested th…

The global spectrum of tree crown architecture Open
Trees can differ enormously in their crown architectural traits, such as the scaling relationships between tree height, crown width and stem diameter. Yet despite the importance of crown architecture in shaping the structure and function o…

The temperature dependence of greenhouse gas production from Central African savannah soils Open
Savannahs cover 20 % of the global land surface, but there have been few studies of greenhouse gas (GHG) dynamics from savannah soils. Here, we assess potential turnover of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) from s…

Composting Urban Biowaste: A Potential Solution for Waste Management and Soil Fertility Improvement in Dolisie, Congo Open
Population growth, urbanization, and changing consumption patterns are contributing to an increase in household waste production, particularly in sub-Saharan Africa. Composting of biowaste presents a sustainable solution by reducing the vo…

Simulating carbon accumulation and loss in the central Congo peatlands Open
Peatlands of the central Congo Basin have accumulated carbon over millennia. They currently store some 29 billion tonnes of carbon in peat. However, our understanding of the controls on peat carbon accumulation and loss and the vulnerabili…

Mapping Water Levels across a Region of the Cuvette Centrale Peatland Complex Open
Inundation dynamics are the primary control on greenhouse gas emissions from peatlands. Situated in the central Congo Basin, the Cuvette Centrale is the largest tropical peatland complex. However, our knowledge of the spatial and temporal …

Allometric equation for Raphia laurentii De Wild, the commonest palm in the central Congo peatlands Open
The world’s largest tropical peatland lies in the central Congo Basin. Raphia laurentii De Wild, the most abundant palm in these peatlands, forms dominant to mono-dominant stands across approximately 45% of the peatland area. R . laurentii…

Allometric options for predicting tropical tree height and crown area from stem diameter Open
Tree height and crown area are important predictors of aboveground biomass but difficult to measure on the ground. Numerous allometric models have been established to predict tree height from diameter (H–D) and crown area from diameter (CA…

Comment on egusphere-2022-580 Open
Abstract. The Central Congo Basin is home to the largest peat swamp in the tropics. Two major vegetation types overlay the peat: hardwood trees, and palms (mostly the trunkless Raphia laurentii variety), with each dominant in different loc…

Allometric equation for the commonest palm in the Central Congo Peatlands, <i>Raphia laurentii</i> De Wild Open
The world’s largest tropical peatland lies in the central Congo Basin. Raphia laurentii De Wild. is a palm which forms dominant to mono-dominant stands across ca. 45 % of the peatland area. However, a lack of allometric equation for this c…

What determines peat swamp vegetation type in the Central Congo Basin? Open
The Central Congo Basin is home to the largest peat swamp in the tropics. Two major vegetation types overlay the peat: hardwood trees, and palms (mostly the trunkless Raphia laurentii variety), with each dominant in different locations. Th…

Tallo: A global tree allometry and crown architecture database Open
Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height and crown size, underpin a wide range of ecological research—from developing and testing theory on forest structure and dynamics, to estimating for…

Current knowledge on the Cuvette Centrale peatland complex and future research directions Open
The Cuvette Centrale is the largest tropical peatland complex in the world, covering approximately 145,000 km2 across the Republic of Congo and the Democratic Republic of Congo. It stores ca. 30.6 Pg C, the equivalent of three years of glo…

Resistance of African tropical forests to an extreme climate anomaly Open
Significance The responses of tropical forests to heat and drought are critical uncertainties in predicting the future impacts of climate change. The 2015–2016 El Niño Southern Oscillation (ENSO) resulted in unprecedented heat and low prec…

Fine Roots Dynamics in Two Forest Strata of a Semi-Deciduous Forest in Northern Republic of Congo Open
The belowground biomass is represented by coarse and fine roots. Concentrated in the superficial horizons of the soil, the fine roots play a crucial role in the functioning of a forest ecosystem. However, studies on their dynamics in natur…
