Intraspecific variability of specific leaf area fosters the persistence of understory specialists across a light availability gradient

Original language description

Forest understory plants are sensitive to light availability, and different species’ groups can respond differently to changing light conditions. A plant trait tightly linked to light capture is specific leaf area (SLA). Studies considering the relative role of within- and among-species SLA variation across different species groups (e.g., specialists and generalists) are rarely implemented in temperate forest understories varying in their maturity. We examined community-level SLA patterns of beech forest understories along a light availability gradient, and for habitat specialists and generalists separately. We then disentangled and quantified the contribution of intraspecific trait variability and interspecific trait differences in shaping SLA patterns. We revealed that the increase in community-level SLA with decreasing light availability was primarily driven by beech forest specialists (and, to a lesser extent, by forest generalists), and this pattern was mainly determined by specialists’ high intraspecific variability. Community-level SLA was therefore formed by different responses at different organizational levels, i.e., withinand among-species, and for separate species’ groups. This study provides insights into factors shaping the shade-tolerance strategy in beech forest understory plants, specialists’ persistence under putative less favourable conditions (i.e., high irradiation) may be fostered by their ability to adjust their light-capture strategiesnintraspecifically.
