Three-dimensional plant architecture and sunlit-shaded patterns: a stochastic model of light dynamics in canopies.

abstract：:Background and Aims Morphological variation in light-foraging strategies potentially plays important roles in efficient light utilization and carbon assimilation in spatially and temporally heterogeneous environments such as tropical moist forest understorey. By considering a suite of morphological traits at various h...
