“…The SOC, TN, and TP concentrations decreased with an increase in soil depth in the study site. The SOC, TN, and TP concentrations in surface soil (0-20 cm) is high, exhibiting remarkable soil nutrient ''surface-aggregation'' (high nutrients in the surface soil layer) (Yang, Liu & An, 2018) (Table 2). The SOC concentrations varied greatly from soil depths of 0-10 to 20-40 cm, with the mean concentration ranging from 27.20 to 6.25 g kg −1 (decreased of 77.02%).…”

“…C:N:P stoichiometry mainly focuses on the interaction and balance of chemical elements in ecological processes (Agren, 2008;Mcgroddy, Daufresne & Hedin, 2004;Ren et al, 2016;Wardle et al, 2004), and provides a useful and effective way to study the distribution, nutrient limitation, and regulatory mechanism of nutrient composition in the ecosystem (Wang et al, 2014). In recent years, many researchers have reported the C:N:P stoichiometry patterns in plant organs (Bai et al, 2019;Yang, Liu & An, 2018), plant communities (Fu et al, 2010;Jiao et al, 2013;Zhao et al, 2017), stand ages (Zhang et al, 2019) and plantations and natural secondary forests (Cao & Chen, 2017;Deng et al, 2016). For example , Yang, Liu & An (2018) found that the C:N:P stoichiometry in leaves, roots, litter, and soil varied hugely, and that the plant community makeup had a significant effect on C:N:P stoichiometry.…”

Background Ecological stoichiometry (C:N:P ratios) in soil is an important indicator of the elemental balance in ecological interactions and processes. Long-term natural vegetation plays an important role in the accumulation and distribution of soil stoichiometry. However, information about the effects of long-term secondary forest succession on soil stoichiometry along a deep soil profile is still limited. Methods We selected Ziwuling secondary succession forest developed from farmland as the study area, investigated the concentrations and stoichiometry of soil organic carbon (SOC), total nitrogen (TN), and total phosphorus (TP) at a depth of 0–100 cm along a 90-year succession chronosequence, including farmland (control), grassland, shrub, early forest, and climax forest. Results SOC and TN concentrations significantly increased with increasing restoration age, whereas soil P concentration remained relatively stable across various successional stages. SOC and TN concentrations decreased with an increase in soil depth, exhibiting distinct soil nutrient “surface-aggregation” (high nutrients concentration in the top soil layer). The soil C:P and N:P ratios increased with an increase in restoration age, whereas the variation of the C:N ratio was small and relatively stable across vegetation succession. The nutrient limitation changed along with vegetation succession, transitioning from limited N in the earlier successional stages to limited P in the later successional stages. Conclusion Our results suggest that more nitrogen input should be applied to earlier succession stages, and more phosphorus input should be utilized in later succession stages in order to address limited availability of these elements. In general, natural vegetation restoration was an ecologically beneficial practice for the recovery of degraded soils in this area. The findings of this study strengthen our understanding of the changes of soil nutrient concentration and nutrient limitation after vegetation restoration, and provide a simple guideline for future vegetation restoration and reconstruction efforts on the Loess Plateau.

“…At present, research is increasing on the nutrient circulation of forest ecosystems with a focus on ecological stoichiometry. Due to the improvement of forest quality and the advantage of high canopy productivity, there are many studies on the C, N, and P ecological stoichiometry of the plant-litter-soil system [25,26]. However, most previously published studies have focused on overstory plant species, largely ignoring understory plant species, which have a faster C and N turnover rate than the overstory plants.…”

Research Highlights: This study identifies the effect of nitrogen (N) and phosphorus (P) addition on stoichiometry correlations between understory plants and soil in subtropical Chinese fir plantations. Background and Objectives: Nitrogen and P are two nutrients limiting forest ecosystem production. To obtain more wood production, N and P are usually applied in plantation management. Changes in soil N and P will generally alter the stoichiometric characteristics of understory plants, which control carbon (C) and nutrient cycles between plants and soil. However, different correlations between plant and soil stoichiometry among functional groups of understory plants have not been investigated, which also impacted element cycling between plants and soil. Materials and Methods: Subtropical Chinese fir plantations were selected for N (100 kg ha−1 year−1) and P (50 kg ha−1 year−1) addition study. We collected fresh litter and the corresponding soil of four understory plants (Lophatherum gracile Brongn., Woodwardia japonica (L.f.) Sm., Dryopteris atrata (Kunze) Ching and Dicranopteris dichotoma (Thunb.) Berhn.) for study of C, N, and P stoichiometric ratios. Results: Nitrogen and P addition affected C, N, and P concentrations and stoichiometric ratios in litter and soil as well as correlations between litter and soil stoichiometric ratios. Understory plant species with different functional types impacted the correlations between plants and soil in C, N, and P stoichiometric ratios, especially correlations between litter C and soil C and N. Conclusions: Changes in soil N and P affect the stoichiometric ratios of understory plants. Functional groups impacted the correlation in C, N, and P stoichiometric ratios between plants and soil, indicating functional groups varied in their impacts on element cycling between plants and soil in plantations with exogenous nutrient addition, which should be considered in future management of plantations with intensive fertilization practice.

Relationship between ecological stoichiometry and community diversity of plant3 ecosystems in the upper reaches of the Tarim Abstract 33 Aim Although it is commonly proposed that nutrient cycling can impact plant 34 community diversity, this relationship has not been fully examined in arid and 35 semi-arid zones. Here, we expand on the framework for evaluating the relationship 36 between biodiversity and ecological stoichiometry by scaling up from the level of the 37 community. 38 Location The upper reaches of the Tarim River (Northwest China, 80°10′-84°36′E, 39 0°25′-41°10′N).40Methods We used multivariate analysis of variance to compare the stoichiometric 41 characteristics and species diversity indices of sampled plant communities. We also 42 measured carbon (C), nitrogen (N), and phosphorous (P) content of plants. We then 43 assessed correlations between community stoichiometry and species diversity through 44 structural equation models (SEM) and redundancy analysis (RDA). 45 ResultsWe found that the differences between stoichiometric characteristics and 46 community diversity indices were highly significant. The Margalef index was 3 47 strongly related to C and P content. The Simpson's index and Shannon-Weaner index 48 were most strongly correlated with C content. Pielou's index was closely related to C 49 and N contents, and the C:N and C:P ratios were important at driving ecological 50 dominance. 51Main Conclusions Our study highlights the importance of ecological stoichiometry in 52 driving community assembly and diversity within a desert ecosystems in northwestern 53 China. The relationship between eclogical stoichiometry in the desert plant 54 community had an effect on species diversity, and it was a good indicator of plant 55 community diversity. 56 KEYWORDS 57 community stoichiometry, diversity, structural equation model, redundancy analysis.58 59 INTRODUCTION 60 Ecological stoichiometry is an important tool for studying ecological processes 61 and ecological functions(Zechmeister-Boltenstern S et al. 2016; Shang B et al. 2018), 62 which is mainly used to explore the dynamic balance of various elements and their 63 interactions (Sterner&Elser 2002; Moorthi S D et al. 2016). The C, N, and P 64 concentrations are vital source elements in plants, and their changes in characteristics 65 limit plant growth(Zeng Q et al. 2016; Sperfeld E et al. 2017 ). It can be used to judge 66 the nutrient limitation of plants and to reveal the utilization strategies of plants for 67 nutrients (Sterner&Elser 2002). At present, stoichiometry has been applied as a new 68 ecological research tool to all levels, such as molecules, cells, individuals, 69 communities and ecosystems (Elser J J et al. 2007; Elser J J et al. 2010; Yan Z B et 70 al. 2016). With the changes of the global environment,terrestrial ecosystems have also 71 undergone significant changes in the aspects of structure, process, function and 72 vegetation distribution pattern (Freudenberger L et al. 2012). Among them, the role of 73 community ecological st...
