We studied the tree-regeneration patterns in three distinct agricultural settlements in the Eastern Amazon to test the influence of land-use mosaics. The following questions are addressed: are the floristic structure and composition of regenerating trees affected by the various land-use types applied in the agricultural settlements? Do tree-regener...
Pycnandra (Sapotaceae), the largest endemic genus in New Caledonia, comprises 66 species classified in six subgenera. We tested phylogenetic relationships and a proposed infrageneric classification by sampling 60 species for sequences of nuclear ribosomal DNA (ETS, ITS, RPB2) and plastid DNA (trnH-psbA) and nine morphological characters. Data were ...

The larvae (grubs) of the African palm weevil are consumed by the majority of inhabitants of the Congo Basin. These larvae are extremely rich in essential food nutrients; they contain proteins, carbohydrates, fats and energy values comparable to those of beef and fish. They are also an excellent source of a range of minerals and vitamins. The explo...

Les paysages végétaux du lac Tchad présentent une grande variété, qui résulte des contraintes imposées par les variations du niveau de l'eau sur la croissance des plantes. En période de Moyen Tchad (1950-1973), les espaces d'eau libre sont importants et la végétation se développe sur les rives du lac. Lors de la phase de recul rapide du lac en 1972...
The causes of the species richness of tropical trees are poorly understood, in particular the roles of ecological factors such as soil composition. The nickel(Ni)-hyperaccumulating tree genus Geissois (Cunoniaceae) from the South-west Pacific was chosen as a model of diversification on different substrates. Here, we investigated the leaf element co...
