| Zusammenfassung |
| Gilbertiodendron dewevrei is a tree species which extensively dominates large patches in
Central Africa. These monodominant forests are often adjacent to higher-diversity forests like
the Scorodophloeus zenkeri forests (called mixed forests). This combination of low and high
diversity forests on otherwise similar edaphic and climatic conditions is ideal to study the
impacts of those two contrasting and widespread forests on various carbon stocks and fluxes.
Whereas carbon pools are increasingly documented for the forests located in the Central
Congo Basin, much less is known about carbon fluxes. This is particularly the case for the
Total Belowground Carbon Allocation to plant structures (TBCA), yet it represents a major
ecosystem C flux.
In addition to estimates of aboveground (minimum diameter 10 cm) and soil (holorganic
layers plus mineral soil down to 2m depth) carbon stocks, we measured soil respiration, fine
root production (forest floor and 0-5 cm) and aboveground foliar litterfall during a
one-year period in at least 106 subplots distributed over the two forests in the Yoko
forest reserve close to Kisangani (Democratic Republic of Congo). TBCA was
derived from the difference between annual rates of soil respiration and aboveground
litterfall C, assuming the stocks of soil organic matter, roots, and litter are near steady
state.
