Le gradient altitudinal sur les sommets tabulaires de Guyane, basé sur l'étude des Arecaceae, des Melastomataceae et des Ptéridophytes

Abstract : Amazonia is mainly covered by lowland forest, however it presents some reliefs. Previous works have shown two types of relief in French Guiana: Inselbergs and plateaus on basic volcanic rocks known as table mountains. Regarding the latter two, vegetation is quite uniform within mountains with comparable altitude and geomorphology. The present research deals mainly with studying floristic composition along an altitudinal gradient with several bioindicators. For this, the study relies on using three vascular plant groups: Arecaceae, Melastomataceae and Pteridophytes. The present research confirms the existence of variation in floristic composition at around 500 meters a.s.l., but also below and above depending on the selected group.
