英文摘要	Specific leaf area (SLA, leaf area to dry mass ratio) is a widely used functional trait in functional ecology. In most studies, SLA is collected by compiling large databases. However, standardized protocols of data collection include only measurements from the sunny side of the crown. We investigated interspecific SLA variability among 179 woody species in common garden conditions of Kórnik Arboretum (W Poland). Then, we quantified the differences in SLA measurements between sunny and shaded parts of the crowns of those species. On average, shade leaves had 43.3% higher SLA than sun leaves. Including differentiation between sun and shade measurements explained an additional 12.2% of SLA variability (in total 95.2% explained by species, family and canopy position). In conclusion, intra-canopy SLA variation can result in providing lower SLA values in databases while following the standardized data collection protocols. Here, we contribute to improved understanding of the importance of SLA variability in the context of its wide use in mechanistic and physiological modelling of ecosystem functioning. © 2020 Elsevier B.V.
