Saisonnalité et déterminisme du pic de fructification en forêt guyanaise. (Fruiting periodicity and its determinants in a lowland rain forest of FrenchGuiana)
The phenology of flowering and fruiting of trees was studied from June 1980 to the end of March 1982 in the lowland rain forest of Piste Saint Elie, FrenchGuiana. The fruiting peak mostly results, at the species level from the adjustment
Importance des buttes de déracinement dans la régénération forestière en Guyane française. (The importance of treefall mounds during forest regeneration in FrenchGuiana)
Remote sensing investigations carried out in FrenchGuiana mainly with radar data is allowing to differentiate morphologies and lithologies, and to map large-scale structures, particularly in the volcanosedimentary units of the Northern Synclinorium
.). In the particular case of the preserved rain forest of FrenchGuiana, the SAR backscattering is mainly due to the shape of the homogeneous canopy modulated by regional morphology.
In this paper, the gold behavior in laterites was compared under a tropical contrasted climate in Banankoro, South Mali, and under an equatorial climate in Yaou, FrenchGuiana. Gold distribution was studied in detail in terms of pedologic horizons

The relationships between bird community structure and habitat structure were studied along a gradient of successional changes in the mangrove of FrenchGuiana.
Processes leading to forest regeneration in a mature rain forest of FrenchGuiana were studied on six plots representing initial stages of regeneration, from 2 to 10 years following clear-cutting.
