While the plant kingdom exhibits some of the highest phenotypic plasticity in nature, their ability to acclimate to the rising temperatures and changing precipitation patterns of the Anthropocene is not fully understood. For deciduous tree species, an area of interest has been intracanopy leaf plasticity, or the multiple phenotypes of leaf form and function a single genotype can express in response to the environment. Intracanopy plasticity significantly contributes to overall individual performance by influencing light penetration, water use efficiency, and the carbon balance of leaves, yet it remains only partially documented across eastern species in situ. Moreover, there is little knowledge on the maladaptive potential and the role of intracanopy leaf plasticity in forest succession to inform predictions of species composition. To characterize the magnitude and direction of intracanopy leaf plasticity, we used a canopy air lift to sample leaves at normalized height intervals for 20 trees across 5 species (Quercus rubra, Acer saccharum, Acer rubrum, Prunus serotina, Betula lenta). To account for the environment, microclimate sensors were placed in the top, middle, and bottom portions of each individual’s crown and solar irradiance was measured directly above the sites of leaf collection. I hypothesized that intracanopy plasticity would be higher in shade tolerant species, since the developmental pathways that allow for shade tolerant leaves during juvenile stages remain available in mature crowns. Preliminary results from the measurements of leaf scans show strong increases in leaf thickness and leaf mass per area (g/m2) as crown height increases. Additionally, there is a strong qualitative increase in minor vein density and thickness for Acer saccharum, and a stark difference in minor vein architecture between Acer sp. and Prunus serotina. Further exploration in estimating the full range of intracanopy leaf plasticity could help our understanding of species ranges and life history strategies of eastern deciduous trees.
