Seasonality, drivers, and isotopic composition of soil CO 2 fluxes from tropical forests of the Congo Basin
Abstract. Soil respiration is an important carbon flux and key process determining the net ecosystem production of terrestrial ecosystems. To …
Article scientifique
Stem and soil nitrous oxide fluxes from rainforest and cacao agroforest on highly weathered soils in the Congo Basin
Abstract. Although tree stems act as conduits for greenhouse gases (GHGs) produced in the soil, the magnitudes of tree contributions …
Article scientifique
Soil greenhouse gas emissions under different land-use types in savanna ecosystems of Kenya
Abstract. Field measurement data on greenhouse gas (GHG) emissions are still scarce for many land-use types in Africa, causing a …
Article scientifique
Flux variability of phyto- and zooplankton communities in the Mauritanian coastal upwelling between 2003 and 2008
Abstract. Continuous multiyear records of sediment-trap-gained microorganism fluxes are scarce. Such studies are important to identify and to understand the …
Article scientifique
Effect of legume intercropping on N 2 O emissions and CH 4 uptake during maize production in the Great Rift Valley, Ethiopia
Abstract. Intercropping with legumes is an important component of climate-smart agriculture (CSA) in sub-Saharan Africa, but little is known about …

Introduction to the French GEOTRACES North Atlantic Transect (GA01): GEOVIDE cruise
Abstract. The GEOVIDE cruise, a collaborative project within the framework of the international GEOTRACES programme, was conducted along the French-led …
Article scientifique
The extant shore platform stromatolite (SPS) facies association: a glimpse into the Archean?
Abstract. Shore platform stromatolites (SPS) were first noted at Cape Morgan on the south-east African seaboard. Since then they have …
Article scientifique
Parallel functional and stoichiometric trait shifts in South American and African forest communities with elevation
Abstract. The Amazon and Congo basins are the two largest continuous blocks of tropical forest with a central role for …
Article scientifique
Influence of infrastructure on water quality and greenhouse gas dynamics in urban streams
Abstract. Streams and rivers are significant sources of nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) globally, and watershed …
Article scientifique
The riverine source of CH 4 and N 2 O from the Republic of Congo, western Congo Basin
Abstract. We discuss concentrations of dissolved CH4, N2O, O2, NO3− and NH4+, and emission fluxes of CH4 and N2O for …
Article scientifique
Upwelling and isolation in oxygen-depleted anticyclonic modewater eddies and implications for nitrate cycling
Abstract. The temporal evolution of the physical and biogeochemical structure of an oxygen-depleted anticyclonic modewater eddy is investigated over a …
Article scientifique
Carbon stocks and dynamics at different successional stages in an Afromontane tropical forest
Abstract. As a result of different types of disturbance, forests are a mixture of stands at different stages of ecological …
Article scientifique
Carbon balance of a grazed savanna grassland ecosystem in South Africa
Abstract. Tropical savannas and grasslands are estimated to contribute significantly to the total primary production of all terrestrial vegetation. Large …
Article scientifique
Small-scale variability in geomorphological settings influences mangrove-derived organic matter export in a tropical bay
Abstract. Organic matter (OM) exchanges between adjacent habitats affect the dynamics and functioning of coastal systems, as well as the …
Article scientifique
Smallholder farms in eastern African tropical highlands have low soil greenhouse gas fluxes
Abstract. Few field studies examine greenhouse gas (GHG) emissions from African agricultural systems, resulting in high uncertainty for national inventories. …
