Hydraulic traits are related to the fundamental functions of conduction and drought resistance, driving plant ecology, evolution, and processes related to climate change. However, these traits are still poorly documented for tropical rainforest, hindering our understanding of tropical tree ecology and the future of tropical forests. Through a trait-based approach combining leaf and stem in-depth anatomy and physiology, this thesis analyses the structure and the functioning of tree leafy shoots, a compartment exposed to the most severe water stress within a tree. This thesis is based on a dataset of 42 canopy tree species sampled in a rainforest in French Guiana, exemplifying a large range of leaf size. A second dataset, aiming at better und...
