A broad range of climatic and biogeographical conditions are represented in the French Overseas Territories, from sub-polar to equatorial, resulting in a high diversity of endemic species. We mobilized data from herbaria, floras, checklists, literature, the expertise of botanists and plant ecologists to compile the most complete dataset on endemic...

ABSTRACT Additions to the genus Vepris Comm. ex A.Juss. (Rutaceae-Toddalieae) in Cameroon. Vepris mbamensis Onana, sp. nov. with its swollen (pulvinate) petiolules is recognized as distinct from all other known species of Vepris in Africa, after study of the African material of the genus. The new species is described and typified. The key to the ca...

RÉSUMÉ La taxonomie des Rutaceae-Toddalieae du Cameroun revisitée sur la base de l'analyse des caractères morphologiques du matériel fertile a permis de reconnaître quatre espèces nouvelles dont Vepris adamaouae Onana, sp. nov. par le limbe des folioles décurrent sur le pétiolule, des inflorescences longues à axes filiformes et des étamines environ...
Article
The taxonomy of Rutaceae-Toddalieae of Cameroon is revisited on the basis of fertile samples, images of specimens, and systematic literature. Species identification based on the correlation of morphological characters of leaves, inflorescences and fruits, let to recognize four new species including Vepris adamaouae Onana, sp. nov. with the lamina o...

The island of Moorea in French Polynesia is representative of a relatively well preserved small tropical oceanic island but both its terrestrial and marine ecosystems are currently under strong anthropogenic pressures. The terrestrial ecosystems are facing an increasing urbanization, and the destruction and modification of their natural habitats by...

Moorea est une petite île océanique tropicale de la Polynésie française relativement bien préservée, mais dont les écosystèmes terrestres et marins sont actuellement soumis à de fortes pressions anthropiques. Le milieu terrestre est confronté à une urbanisation croissante, à la destruction ou à la modification des habitats naturels pour l’extension...
Conference Paper
Modéliser les aires de répartition pourrait s'avérer d'un grand intérêt pour planifier la conservation et l'utilisation durable de la biodiversité. Ma1heureusement, dans les pays tropicaux, le manque de données limite encore fortement la validation et l'usage des modèles. En utilisant diverses sources issues de spécimens d'herbiers, d'inventaires f...

For centuries, botanists have collected plant specimens across the Guianas (Guyana, Suriname, French Guiana). In this paper, we describe the construction of a comprehensive angiosperm specimen database for the Guianas and examine: (1) the historical accumulation of species and specimens; (2) the pattern of geographical expansion of collecting effor...

Au Sénégal, les communications électroniques reposent essentiellement sur des organismes de recherche (institutionnels ou non gouvernementaux) qui les utilisent principalement pour des besoins de communication avec leurs différents centres et partenaires. Le Réseau Intertropical d'Ordinateurs, qui représente l'un des premiers maillons de l'Internet...
Article
Satellite imagery has been a key factor in the success of the Programme for optimization of the farm irrigation in the Senegal middle valley. Thus the images have enabled the old maps to be updated as regards dykes, roads and irrigated zones. Radiometric site investigations are now necessary, as a preliminary to extension of the study of the entire...
