“…Studies conducted in forest dynamic plots (Anderson-Teixeira et al, 2015) usually define seedlings as individuals with height > 10 or 20 cm and dbh < 1 cm that include a wide range of sizes. The influence of plant size on leaf traits is supported by recent findings (Dayrell et al, 2018;Forrestel et al, 2015;Martin & Thomas, 2013;Mason et al, 2013;Park et al, 2019). Second, micro-environmental heterogeneity in our plot, such as spatial variation in light availability, can also drive leaf trait variation among individuals (Rozendaal et al, 2006).…”

“…Our finding of the pattern of SLA declining with increasing plant size of C . dunniana , agrees with this expectation and is in line with the pattern widely reported from forests in other parts of the world (e.g., Kenzo et al, 2015 ; Martin & Thomas, 2013 ; Park et al, 2019 ; Thomas & Winner, 2002 ). However, the leaf area of C .…”

“…In the forest, as a plant increases in size, it generally faces increasingly higher irradiance and hydraulic resistance at higher forest strata (Rozendaal et al, 2006 ; Thomas & Bazzaz, 1999 ), as a result, leaf traits usually show corresponding shifts toward more conservative resource‐use strategy (e.g., Cavaleri et al, 2010 ; Dayrell et al, 2018 ; He & Yan, 2018 ; Ishida et al, 2005 ). Larger conspecific individuals usually have smaller sized leaves (Koch et al, 2004 ), smaller specific leaf area (SLA) (Kenzo et al, 2015 ; Thomas & Winner, 2002 ), as well as higher leaf dry‐matter content (LDMC) (Park et al, 2019 ). These size‐dependent trait shifts are interpreted as plant adopting an increasingly more conservative light and water‐use strategies in response to high light and drought stress, through acclimation and plasticity.…”

Aims Understanding the joint effects of plant development and environment on shifts of intraspecific leaf traits will advance the understandings of the causes of intraspecific trait variation. We address this question by focusing on a widespread species Clausena dunniana in a subtropical broad‐leaved forest. Methods We sampled 262 individuals of C. dunniana at two major topographic habitat types, the slope and hilltop, within the karst forests in Maolan Nature Reserve in southwestern China. We measured individual plant level leaf traits (i.e., specific leaf area (SLA), leaf area, leaf dry‐matter content (LDMC), and leaf thickness) that are associated with plant resource‐use strategies. We adopted a linear mixed‐effects model in which the plant size (i.e., the first principal component of plant basal diameter and plant height) and environmental factors (i.e., topographic habitat, canopy height, and rock‐bareness) were used as independent variables, to estimate their influences on the shifts of leaf traits. Key Results We found that (1) plant size and the environmental factors independently drove the intraspecific leaf trait shifts of C. dunniana, of which plant size explained less variances than environmental factors. (2) With increasing plant size, C. dunniana individuals had increasingly smaller SLA but larger sized leaves. (3) The most influential environmental factor was topographic habitat; it drove the shifts of all the four traits examined. Clausena dunniana individuals on hilltops had leaf traits representing more conservative resource‐use strategies (e.g., smaller SLA, higher LDMC) than individuals on slopes. On top of that, local‐scale environmental factors further modified leaf trait shifts. Conclusions Plant size and environment independently shaped the variations in intraspecific leaf traits of C. dunniana in the subtropical karst forest of Maolan. Compared with plant size, the environment played a more critical role in shaping intraspecific leaf trait variations, and potentially also the underlying individual‐level plant resource‐use strategies.

“…Mass‐based leaf N content (N mass ) was positively related to tree size in evergreen trees (He & Yan, ; Kenzo et al, ) and in a deciduous tree (Sendall & Reich, ), whereas no significant correlation was found in two evergreen conifers (Niinemets, ). The size dependence of N mass was different between two tropical tree species (Martin & Thomas, ) and between two deciduous tree species (Park et al, ). The correlation between leaf longevity and plant size was negative in Chinese pine ( P. tabulaeformis Carr.)…”

1. Many leaf traits strongly vary with tree size and environmental factors, but the importance of these factors to intraspecific variations of leaf traits in forest trees has rarely been simultaneously evaluated.2. We measured needle longevity and specific leaf area (SLA) and nitrogen (N) content of every needle age (0-to 4-year old) for 65 individuals with 0.3-100 cm diameter at breast height (DBH) for an evergreen coniferous species, Pinus koraiensis Sieb. et Zucc., in Northeast China. We simultaneously evaluated the effects of tree size (DBH or tree height) and environment factors (light intensity, soil N content and water availability) on the needle longevity, SLA, foliage N content as well as the slopes of regressions of SLA and foliage N content against needle age.3. All of the studied leaf traits and slopes of regressions of SLA and foliage N content against needle age were significantly related to tree size. Tree height had a greater impact on SLA and area-based leaf N content (N area ), whereas DBH was more important for needle longevity and mass-based leaf N content (N mass ). The environment variables, light intensity, soil N content and water availability, were rather minor factors for trait variations compared with tree size. Significant influence of light intensity was found only on needle longevity, and soil N and water availability had no effects on the leaf traits.4. Our study clearly showed that tree size is an important driver of intraspecific variations in the key leaf traits of P. koraiensis in a natural forest. We also emphasize the importance of DBH or tree height varies depending on leaf traits, suggesting various mechanisms of size effects on the intraspecific variations in leaf traits. We suggest that ecological significance of leaf trait variations needs reconsideration incorporating tree size effect.
