'Outer' tree canopy leaves influence the sunlight reaching inner canopy leaves by changing their shape, says a new study. The shape and physiology of leaves within the tree canopy is not constant, and can vary depending on their position within the tree crown. This phenomenon is expected to have important consequences for how trees cope with stress and use resources. A new study describes how the leaves in the outer canopy of olive trees can influence the light environment within the canopy...
