The database comprises more than thirty traits including autecology . habitat associations and reproductive phenology wood structure . density and tension characteristics and physiology at the whole plant . carbon and nitrogen isotopes and leaf level . specific leaf area photosynthetic capacity . The current database describes traits for about nine hundred species from three hundred genera in one hundred families. For more than sixty species data on twelve morphological and ecophysiological traits are provided for individual plants under different environmental conditions and at different ontogenetic stages. The database is thus unique in permitting intraspecific analyses such as the effects of ontogenetic stages or environmental conditions on trait values and their relationships. plant traits tropical forest French Guiana functional groups plasticity ontogeny Résumé - Une base de données sur l autecologie des arbres de la forêt tropicale de Guyane franẹaise. Nous présentons une base de données sur l autécologie des arbres de la foret tropicale de Guyane fran aise. La base contient des données sur plus de trente traits concernant l autécologie par exemple les préférences d habitat et la phénologie reproductive la structure du bois par exemple la densité et les caractéristiques du bois de tension et la physiologie aux niveaux de la plante entière par exemple
