Light is a critical environmental factor that influences nutrient uptake in roots and the subsequent use of nutrients, which is necessary to sustain plant growth. The positive effect of red light on phosphorus uptake has now been defined, along with

Niche differentiation is a key issue in the current debate on community assembly mechanisms. In highly diverse moist tropical forests, tree species sensitivity to canopy openness is thought to be a major axis in niche differentiation. In the past, th

Can functional classification of tropical trees predict population dynamics after disturbance?

Autor: Olivier Flores, Sylvie Gourlet-Fleury, E. Gamier, Matthieu Delcamp

Publikováno v: Journal of Vegetation Science

Question: How far can we simplify the floristic complexity of a tropical rainforest into functional groups in order to predict tree population dynamics after logging-induced disturbance? Location: Paracou experimental site, French Guiana. Methods: We

The yearly renewal of leaves and their holding organs (the leafy shoot) represent an energetic cost for saplings. The contribution of both biochemical (tissue construction cost, CC) and morphological traits (biomass partitioning and leaf mass per uni

De nombreux arbres de forêts tropicales présentent des répartitions spatiales agrégées dont le déterminisme et la dynamique soulèvent de multiples questions touchant le fonctionnement global de ces écosystèmes. Le Wacapou (Vouacapoua america

Tree diversity in tropical rain forests: a validation of the intermediate disturbance hypothesis

Autor: Jean-François Molino, Daniel Sabatier

Publikováno v: Science

The “intermediate disturbance hypothesis,” which postulates maximum diversity at intermediate regimes of disturbance, has never been clearly proved to apply to species-rich tropical forest tree communities and to local-scale canopy disturbances t
