Planktons are a major component of food web structure in aquatic ecosystems. Their distribution and community structure are driven by the combination and interactions between physical, chemical, and biological factors within the environment. In the present study, water quality and the community structure of phytoplankton and zooplankton were monthl...

In application of the European Water Framework directive aiming to achieve a “good ecological status” for all waters, phosphorous removal from domestic wastewater can be of importance before discharging into natural receiving bodies, especially for small communities localized upstream of catchment areas or in zones sensitive to eutrophication.As ru...
L'optimisation de la production agricole a longtemps été le seul but de la recherche agricole, notamment dans les pays du sud où la demande en aliments et en matières premières augmente rapidement et où les sols souvent dégradés fournissent peu d'éléments nutritifs. La nécessité d'un changement de paradigme est maintenant pleinement acquise. L'obje...
In Sudano-Sahelian agriculture, organic amendments are often limited by resource availability. Small branches (ramial wood, RW) represent an organic resource found in many landscapes but little is known about their effects. This field trial (2007–2009) studied the effects of RW or straw at low application rate (0.69 Mg C ha−1 year−1) on topsoil car...

The objective of this study was to evaluate the relationships between the spectra in the Vis-NIR range and the soil P concentrations obtained from the Pm and Prem extraction methods as well as the effects of these relationships on the construction of models predicting P concentration in Oxisols. Soil samples’ spectra and their Pm and Prem extractio...
