“…As a result, we hypothesized that there might be a link between NI and plant individual size. Furthermore, studies have shown that the structural characteristics of leaves change with plant size, though some changes are not significant ( Price et al., 2014 ; Huang et al., 2016 ; Chang et al., 2021 ). For leaves that initially grow between the internodes, there is a larger number of nodes per assimilative branch, which indicates that the shrub originally had more full-grown leaves.…”

Shrubs play a major role in maintaining ecosystem stability in the arid deserts of Central Asia. During the long-term adaptation to extreme arid environments, shrubs have developed special assimilative branches that replace leaves for photosynthesis. In this study, four dominant shrubs with assimilative branches, namely Haloxylon ammodendron, Haloxylon persicum, Calligonum mongolicum, and Ephedra przewalskii, were selected as the research objects, and the dry mass, total length, node number, and basal diameter of their assimilative branches and the average length of the first three nodes were carefully measured, and the allometric relationships among five traits of four species were systematically compared. The results indicated that: (1) Four desert shrubs have different assimilative branches traits. Compared with H. persicum and H. ammodendron, C. mongolicum and E. przewalskii have longer internodes and fewer nodes. The dry mass of H. ammodendron and the basal diameter of H. persicum were the smallest; (2) Significant allometric scaling relationships were found between dry mass, total length, basal diameter, and each trait of assimilative branches, all of which were significantly less than 1; (3) The scaling exponents of the allometric relationship between four traits and the dry mass of assimilative branches of H. persicum were greater or significantly greater than those of H. ammodendron. The scaling exponents of the relationships between the basal diameter, dry mass, and total length of E. przewalskii were higher than those of the other three shrubs. Therefore, although different species have adapted to drought and high temperatures by convergence, there was great variability in morphological characteristics of assimilative branches, as well as in the scaling exponents of relationships among traits. The results of this study will provide valuable insights into the ecological functions of assimilative branches and survival strategies of these shrubs to cope with aridity and drought in desert environments.

“…Plants with a low SLA value typically have a high Lth value because more materials are used to create protective structures and enhance the density of mesophyll cells in the leaf [36]. In general, plants with a high Lth tend to have a high LA, which reduces the heat transfer between the leaves and the surrounding air and lowers the CO 2 and water vapour diffusion rate from the leaves [55]. In contrast, our study showed high Lth but low LA values in fragmented woodlands.…”

Habitat fragmentation threatens the sustainability of ecological restoration. Understanding the variation in intraspecific traits helped to reveal the functional resource-use strategies of plants in response to environmental changes. We sampled different landscape types of forest configurations, where the most widespread species was Robinia pseudoacacia. From each plot, from two to five R. pseudoacacia individuals were selected for further examinations. Plant development and leaf traits—leaf area (LA), specific leaf area (SLA), leaf dry matter content (LDMC), and leaf thickness (Lth)—were measured in 135 individuals in total. The effects of plant development and landscape fragmentation on R. pseudoacacia leaf traits were assessed using linear mixed-effects models. The environmental factors explained the changes in leaf traits of R. pseudoacacia individuals, and the effect of stand type was the most significant. Compared with continuous forests, R. pseudoacacia individuals in fragmented forests adopted a more conservative resource-use strategy, with smaller LA and SLA and larger Lth and LDMC values. With an increase in landscape heterogeneity, SLA increased and LDMC decreased. In conclusion, the occurrence of landscape fragmentation plays a substantial role in inducing changes in leaf characteristics. The restoration of fragmented forests to continuous forests requires the appropriate addition of land-use types and systematic adjustment of landscape configurations.

“…When the specific leaf area is low, the products of photosynthesis are mostly invested to increase the length or resistance of the water diffusion pathway [37]. In addition, the leaf dry matter content, leaf thickness, and leaf tissue density increased correspondingly for the purpose of reducing water loss induced by transpiration, thus increasing the water usage efficiency and the plant suitability to drought and aridity [38,39]. The plantation at the slow end is a conservative strategy, which usually includes a low respiration rate and low leaf turnover rate to prevent carbon loss, with enhancement of the plant resistance to adversity [40].…”

To explore the changes of leaf functional traits of Zanthoxylum planispinum ‘dintanensis’ with growth and development and its relationship with soil properties, which can clarify the response of the plantation to soil properties and suitable strategy. The research results can provide a scientific basis for plantations management. We explored the response of leaf functional traits to soil by using redundancy analysis in 5–7-, 10–12-, 20–22-, and 28–32-year Z. planispinum ‘dintanensis’ plantations. The results showed that: (1) The coefficients of variation of leaf traits ranged from 0.41% to 39.51%, with mostly medium and low variation, with the lowest variability in leaf water content (0.51–0.85%); The 5–7, 10–12, 20–22-year-old plantations were laid at the “slow investment-return” end of the economic spectrum while 28–32-year plantations were close to “fast investment-return” end. (2) The Z. planispinum ‘dintanensis’ tended to suit the environment via making trade-off and coordination of leaf functional traits. Leaf dry matter content decreased with an increase in leaf carbon/leaf nitrogen ratio, which is the trade-off between nitrogen usage efficiency and nutrient fixation capacity in Z. planispinum ‘dintanensis’. (3) Redundancy analysis suggested that soil carbon/nitrogen ratio, soil total calcium, soil water content, soil available phosphorus, soil carbon/calcium ratio were highly correlated with leaf functional traits, while soil elemental stoichiometry had a greater reflection on leaf functional traits than their own content.
