“…The product of leaf lamina length and width can predict individual leaf area, and this relationship holds for diverse taxa and for different growth conditions, without considering the underlying leaf structures such as venation ( Blonder et al , 2020 ; Kawai and Okada, 2020 ), lobation ( Schuepp, 1993 ; Kusi and Karsai, 2020 ), lamina folding ( Fleck et al , 2003 ; Deguchi and Koyama, 2020 ), epidermal features ( Maslova et al , 2021 ) and internal mesophyll structures ( Oguchi et al , 2005 ), all of which are known to differ among angiosperm species and under different environmental conditions. The consistency of the shoot-level results among eudicots, Magnoliids and monocots obtained herein may imply that the present results may also be generalized across angiosperms, as is the case for individual leaves.…”

Background and Aims An individual plant consists of different-sized shoots, each of which consists of different-sized leaves. To predict plant-level physiological responses from the responses of individual leaves, modeling this within-shoot leaf size variations is necessary. Within-plant leaf trait variation has been well investigated in canopy photosynthesis models but not so well in plant allometry. Therefore, integration of these two different approaches is needed. Methods We focused on an established leaf-level relationship that the area of an individual leaf lamina is proportional to the product of its length and width. The geometric interpretation of this equation is that different-sized leaf laminas from a single species share the same basic form. Based on this shared basic form, we synthesized a new length-times-width equation predicting total shoot leaf area from the collective dimensions of leaves that comprise a shoot. Furthermore, we showed that several previously established empirical relations, including the allometric relationships between total shoot leaf area, maximum individual leaf length within the shoot, and total leaf number of the shoot, can be unified under the same geometric argument. We tested the model predictions using five species, all of which have simple leaves, selected from diverse taxa (Magnoliids, Monocots, and Eudicots) and from different growth forms (trees, erect herbs and rosette herbs). Key Results For all five species, the length-times-width equation explained within-species variation of total leaf area of a shoot with high accuracy (R 2 > 0.994). These strong relationships existed despite leaf dimensions scaling very differently between species. We also found good support for all derived predictions from the model (R 2 > 0.85). Conclusions Our model can be incorporated to improve previous models of allometry that do not consider within-shoot size variation of individual leaves, providing a cross-scale linkage between individual leaf-size variation and shoot-size variation.

“…There was also a certain correlation between the functional traits in plants' life history strategy and survival abilities (Kawai and Okada, 2020). The optimal functional combination among traits is formed by the synergistic changes among traits in plants, to achieve a good adaptation to the constantly changing external environment (Jeffrey et al, 2014;Mello et al, 2020).…”

“…Global warming is associated with an increase in climate extremes (Jackson and Colmer, 2005) such as frequent and prolonged floods which make many ecosystems more vulnerable. Flooding is a crucial factor for triggering the dramatic alteration in composition, structure, distribution pattern, and functional traits of plant communities (Kogan, 1990;Kuroha and Ashikari, 2020;Li et al, 2020). Consequently, increasing attention has been paid to the analysis of plant functional traits and vegetation responses to environmental changes (Lamarque et al, 2014;Violle et al, 2014) in order to provide a scientific basis for predicting the spatial-temporal variation mechanism of plant leaf traits (Myers-Smith et al, 2019).…”

A unique riparian ecosystem has been created as a result of anti-seasonal flooding after reservoir operations, which notably influences the distribution patterns of plant communities and their functional characteristics in the riparian zone. Plant functional traits which reflect the physiological and ecological processes of plants in particular ecosystems are crucial for indicating the variations in the ecosystem structure and function. To better understand the adaptation strategies of plants to hydrological changes and provide a scientific basis for the selection of species in the re-vegetation of the newly formed ecosystems, 14 leaf functional traits and leaf economics spectrum (LES) of 19 dominant plants under different hydrological conditions were investigated in the water level fluctuation zone (WLFZ) of the Three Gorges Reservoir (TGR). The results showed that anti-seasonal flooding has significant effects on the leaf functional traits of plants (P < 0.05). The net photosynthetic rate of annual plants was significantly higher than that of perennial plants (P < 0.05), and there was a significant correlation between leaf phenotypic and photosynthetic traits (P < 0.05). Canonical correspondence analysis showed that soil water content and available phosphorus were the main factors affecting the leaf function of dominant species, indicating that hydrologic factors were still important environmental factors affecting leaf functional traits of dominant species in the WLFZ. And annuals from the WLFZ have characteristics of thick leaves, high photosynthetic rate, short lifespan, and high nutrient concentrations, which make them close to the fast investment-return end of LES. On the contrary, perennials are close to the slow investment-return end of LES. The high productivity investment of annuals is better than the high defense investment of perennials for adapting to the special habitats in the WLFZ. These results indicated that different functional plants in the WLFZ of the TGR under different hydrological regimes can adopt different strategies by weighing the associations and trade-offs between their economic traits.

Background Functional trait-based ecological research has been instrumental in advancing our understanding of environmental changes. It is still, however, unclear how the functional traits of urban plants respond to atmospheric particulate matter, and which trade-off strategies are shown. In order to explore the variation of plant functional traits with the gradient of urban atmospheric particulate matter, we divided atmospheric particulate matter into three levels according to road distance, and measured the variation of six essential leaf functional traits and their trade-off strategies. Results Here, we show that the functional traits of plants can be used as predictors of plant response to urban atmospheric particulate matter. Within the study, leaf thickness, leaf dry matter content, leaf tissue density, stomatal density were positively correlated with atmospheric particulate matter. On the contrary, chlorophyll content index and specific leaf area were negatively correlated with atmospheric particulate matter. Plants can improve the efficiency of gas exchange by optimizing the spatial distribution of leaf stomata. Under the atmospheric particulate matter environment, urban plants show a trade-off relationship of economics spectrum traits at the intraspecific level. Conclusion Under the influence of urban atmospheric particulate matter, urban plant shows a “slow investment-return” type in the leaf economics spectrum at the intraspecific level, with lower specific leaf area, lower chlorophyll content index, ticker leaves, higher leaf dry matter content, higher leaf tissue density and higher stomatal density. This finding provides a new perspective for understanding the resource trades-off strategy of plants adapting to atmospheric particulate matter.
