“…While the construction of palisade tissue necessitates more carbon investment than spongy tissue (John et al, 2017), the palisade is also much more efficient in terms of light interception and thus photosynthetic capacity, and the trade-off suggests that this would be selected and potentially underlie greater resource acquisition across species. Such pattern was also revealed across communities and suggests that this trade-off is conserved during habitat filtering that drives specific plant species together, irrespective of the climate or species in the given community (Tatarko and Knops, 2018;Song and Liu, 2019). Indeed, these traits were also strongly related to chlorophyll and nitrogen contents at both the species and community levels, reflecting evolution of traits by optimal design, and consistent with greater productivity that would scale to the level of the whole ecosystem (Wright et al, 2004;He et al, 2018).…”

Multi-dimensional trait mechanisms underlying community assembly at regional scales are largely unclear. In this study, we measured leaf economic, hydraulic and anatomical traits of 394 tree species from tropical to cold temperate forests, from which we calculated the leaf trait moments (mean, variance, skewness, and kurtosis) using community-weighted methods. Economic and hydraulic traits were decoupled at the species level, but coupled at the community level, and relationships between leaf traits in observed communities were stronger than that in null communities, suggesting that the adaptive mechanisms of plant species may be different. Furthermore, leaf economic traits were distributed more evenly across species occupying communities with lower temperature and precipitation, whereas hydraulic traits were distributed more evenly under lower water availability. This suggests that limiting similarity of specific leaf traits within communities would be enhanced when related-resources are limited, and highlights the independent assembly of leaf economics and hydraulic traits in terms of functional evenness. Importantly, the moments of leaf economic and hydraulic traits of observed communities explained more variation in ecosystem productivity than that of null communities, indicating ecosystem productivity depended on traitbased community assembly. Our results highlight the principles of community assembly regarding multi-dimensionsional traits in natural forests at a regional scale.

“…Although soil nutrients substantially decreased after being burned, plants adopt a growth strategy in response to severe environmental changes ( Song et al, 2021 ). These flexible growth strategies of the plant would change resource allocations among organs to enable them to adapt to the nutrient-insufficient environment ( Wright and Sutton-Grier, 2012 ; Song and Liu, 2019 ). The results of our study show that the C, N, and P concentrations were higher in leaf than in fine roots.…”

Plant stoichiometry and nutrient allocation can reflect a plant’s adaptation to environmental nutrient changes. However, the allocation strategies of carbon (C), nitrogen (N), and phosphorus (P) between leaf and fine root in response to wildfire have been poorly studied. Our primary objective was to elucidate the trade-off of elemental allocation between above- and belowground parts in response to the soil nutrient changes after a wildfire. We explored the allocation sloping exponents of C, N, and P between leaf and fine root at the species and community levels at four recovery periods (year 2, 10, 20, and 30) after moderately severe wildfire and one unburned treatment in boreal forests in Great Xing’an Mountains, northeast China. Compared with the unburned treatment, leaf C concentration decreased and fine root C increased at year 2 after recovery. The leaf N concentration at year 10 after recovery was higher than that of unburned treatment. Plant growth tended to be limited by P concentration at year 10 after recovery. Nutrient allocation between leaf and fine root differed between species and community levels, especially in the early recovery periods (i.e., 2 and 10 years). At the community level, the nutrient concentrations of the leaf changed more as compared to that of the fine root at year 2 after recovery when the fine root nutrients changed more than those of the leaf. The different C, N, and P allocation strategies advanced the understanding of plant adaptation to soil nutrient changes during the postfire ecosystem restoration.

“…Leaves are the photosynthetic organs of plants, and as such are involved in the circulation of matter and the flow of energy through an ecosystem. Thus, leaf functional traits can be considered to represent the response of a plant to environmental factors (Onoda et al, ; Shi, Liu, et al, ; Shi et al, ; Song & Liu, ; Su et al, ). Plant N and P are important elements that influence plant metabolism, energy transmission, and ecological processes (Abdalaroberts et al, ).…”

The relationship between plants and the environment is a core area of research in ecology. Owing to differences in plant sensitivity to the environment at different life history stages, the adaptive strategies of plants are a cumulative result of both their life history and environment. Previous research on plant adaptation strategies has focused on adult plants, neglecting saplings or seedlings, which are more sensitive to the environment and largely affect the growth strategy of subsequent life stages. We compared leaf N and P stoichiometric traits of the seedlings, saplings, and adult trees of Acer mono Maxim and different altitudes and found significant linear trends for both life history stages and altitude. Leaf N and P content by unit mass were greatly affected by environmental change, and the leaf N and P content by unit area varied greatly by life history stage. Acer mono leaf N‐P utilization showed a significant allometric growth trend in all life history stages and at low altitudes. The adult stage had higher N‐use efficiency than the seedling stage and exhibited an isometric growth trend at high altitudes. The N‐P utilization strategies of A. mono leaves are affected by changing environmental conditions, but their response is further dependent upon the life history stage of the plant. Thus, this study provides novel insights into the nutrient use strategies of A. mono and how they respond to the environmental temperature, soil moisture content along altitude and how these changes differ among different life history stages, which further provide the scientific basis for the study of plant nutrient utilization strategy on regional scale.
