Benjamin Blonder, Cyrille Violle and Brian J. Enquist Assessing the causes and scales of the leaf economics spectrum using venation networks in Populus tremuloides Journal of Ecology 101
The leaf economics spectrum (LES) describes interspecific leaf trait correlations. We develop theory for the LES based on trade-offs in leaf venation networks using Populus tremuloides clones. We show that the global LES correlations are also found across leaves within individual organisms and may be explained by variation in venation network geometry and its scaling with leaf morphology.
