Abstract

Canopy structure along with leaf form and function determine global rates of photosynthesis and transpiration and, thus, heavily influence the global carbon, water, and energy cycles. Key unknowns remain regarding how leaf physiology and canopy structure respond to both temporal and spatial mesoclimatic changes, and the within-canopy microclimate. In this session, we will explore the relative roles of leaf physiology, phenology, microclimate, and canopy structure in determining ecosystem states, traits, and rates. We are particularly interested in studies that use novel approaches to examine changes in canopy form and function, particularly those that bridge traditional boundaries with new theory, observations, and models. We encourage submissions of studies merging field and experimental observations, with both near-surface and remote sensing techniques. We also encourage empirical and modeling studies examining canopy processes across scales, from seconds to decades and from the leaf to the globe.
