Global leaf trait estimates biased due to plasticity in the shade [Nature Plants]

Keywords : ecophysiology, ecosystem ecology, plant physiology

The study of leaf functional trait relationships, the so-called leaf economics spectrum is based on the assumption of high-light conditions (as experienced by sunlit leaves). Owing to the exponential decrease of light availability through canopies, however, the vast majority of the world’s vegetation exists in at least partial shade. Plant functional traits vary in direct dependence of light availability, with different traits varying to different degrees, sometimes in conflict with expectations from the economic spectrum.(...)
