    Description

    Physiological ecologists have been fascinated by height- or position-linked differences of leaf morphology within tall trees >25 m, but the exact cause is still debated, i.e., is it due to light or height-induced water stress? The aim of this study was to demonstrate that relatively small trees (<15 m) have leaf morphologies that vary with height and that such variation depends on sitemoisture variability. Leaves were collected from Robinia pseudoacacia trees at two sites in China with contrasting moisture variability to gather baseline data on leaf morphology parameters.
