“…Similarly, in this study, the leaf length, leaf width, and leaf thickness of interspecific and intraspecific variation decreased with the decrease in water content, which greatly reduced the specific leaf area and led to better adaptation to the drought environment. Some experts argued that in order to achieve maximum survival, the plasticity of leaf area and specific leaf area should be increased to cope with the limitation of light resources and soil nutrients in the community [49]. In this study, the variation in leaf length, leaf width, and leaf thickness with the direction of the water gradient also confirmed this result.…”

Studying the inter- and intraspecific variation in plant functional traits elucidates their environmental adaptation strategies and the mechanisms of community construction. This study selected the desert plant community in the Lake Ebinur watershed as the research object and considered five different traits: plant height (H), diameter at breast height/base diameter (DBH/BD), leaf length (LL), leaf width (LW), and leaf thickness (LT). This study used redundancy and correlation analyses to investigate the inter- and intraspecies variation in community-level traits, its relationship with soil physicochemical factors under different soil moisture conditions, and their change laws. We also used variance decomposition to analyze the contribution of inter- and intraspecific variation to community weighting. The results showed the following: (1) the values of the plant community functional traits varied according to the water gradient, and the LL (p = 0.01) and DBH/BD (p = 0.038) varied significantly; (2) for intraspecific variation, the DBH/BD variation was high at a low moisture gradient, LL (p = 0.018) and LT (p = 0.030) variation were high at a high moisture gradient, and the differences were significant; (3) under a high moisture gradient, inter- and intraspecific variation contributed 85.8% and 35.7% to community weighting, respectively, whereas under low moisture gradients, inter- and intraspecific variation contributed 53.3% and 25.1%, respectively.

“…Meanwhile, there was a correlation between leaf structure and chemical traits in the community. SLA, LDMC, and LN all reflect adaptation strategies to the environment (Wright et al, 2004 ; Xun et al, 2020 ), and there was a significant positive correlation between SLA and LN, reflecting photosynthetic capacity and nutrient turnover at the species and community levels. SLA significantly correlated with LT, LDMC, and LC negatively, while no correlation was observed between LDMC and LT (Tables 4 and 5 ), indicating that LT and LDMC affected SLA in different ways in this community.…”

Neutral‐theory‐based stochastic and niche‐theory‐based determinative processes are commonly used to explain the mechanisms of natural community assembly. However, considerable uncertainty remains regarding the relative importance of different ecological processes in shaping forest communities. Functional traits and phylogeny provide important information about plant environmental adaptation strategies and evolutionary history and promise a better mechanistic and predictive understanding of community assembly. Based on nine leaf functional traits and phylogenetic data of 18 dominant species in a Lithocarpus glaber–Cyclobalanopsis glauca evergreen broad‐leaved forest, we analyzed the variation in traits, explored the influence of phylogeny and environment on leaf traits, and distinguished the relative effects of spatial and environmental variables on functional traits and phylogenetic compositions. The results showed the following: (i) Leaf traits had moderate intraspecific variation, and significant interspecific variation existed especially among life forms. (ii) Significant phylogenetic signals were detected only in leaf thickness and leaf area. The correlations among traits both supported “the leaf economics spectrum” at the species and community levels, and the relationships significantly increased or only a little change after removing the phylogenetic influence, which showed a lack of consistency between the leaf functional trait patterns and phylogenetic patterns. We infer the coexistent species tended to adopt “realism” to adapt to their habitats. (iii) Soil total potassium and phosphorus content, altitude, aspect, and convexity were the most critical environmental factors affecting functional traits and phylogenetic composition. Total environmental and spatial variables explained 63.38% of the variation in functional trait composition and 47.96% of the variation in phylogenetic structures. Meanwhile, the contribution of pure spatial factors was significantly higher than that of the pure environment. Stochastic processes played dominant roles in driving community functional trait assembly, but determinative processes such as environmental filtering had a stronger effect on shaping community phylogenetic structure at a fine scale.

We sought to assess effect of plant environmental adaptation strategies and evolutionary history and quantify the contribution of ecological processes to community assembly by measuring functional traits and phylogenetic composition in local forest community. We selected 18 dominant tree species in a Lithocarpus glaber–Cyclobalanopsis glauca evergreen broad-leaved forest and measured nine leaf functional traits and phylogenetic data of each species. We analyzed the variation in traits and trade-off relationships, tested phylogenetic effects on leaf functional traits, explored the influence of phylogeny and environment on leaf functional traits, and distinguished the relative effects of spatial and environmental variables on functional traits and phylogenetic compositions. The results showed the following: (i) Leaf traits had moderate intraspecific variation, and significant interspecific variation existed especially among life forms. (ii) Significant phylogenetic signals were detected only in leaf thickness and leaf area. The correlations among traits both supported “the leaf economics spectrum” at the species and community levels, and the relationships significantly increased or only a little change after removing the influence of phylogeny, which showed a lack of consistency between the leaf functional trait patterns and phylogenetic patterns.
