Ontogenetic shifts in wood anatomy and leaf traits in tropical dry forests. [PDF]

New Phytol
Summary Trees experience changes in environmental conditions and biophysical constraints as they grow that may lead to shifts in functional traits. While ontogenetic shifts in leaf traits are relatively well understood, changes in wood anatomy traits from seedlings to adults are less clear, especially in tropical dry forests where drought strongly ...
