“…Mycorrhizal fungi are important members of the plant microbiota and can form a symbiotic relationship with the root of most plants on the earth ( Averill et al, 2019 ). More than 92% of plant species have mycorrhiza ( Sizonenko et al, 2020 ). Because mycorrhizal fungi are ubiquitous in terrestrial ecosystems, they are an important part of the soil biota and affect where and how plants grow ( Johnson et al, 2010 ).…”

Mycorrhizal strategies include mycorrhizal statuses and mycorrhizal types, which are important reflections of the functional characteristics of ecosystems. The stoichiometry of carbon, nitrogen, and phosphorus in plant organs is an important part of ecosystem functions, which has an important impact on the nutrient cycle of the ecosystem. The concentration of carbon, nitrogen, and phosphorus played a crucial role in ecosystem functioning and dynamics. The purpose of this study is to provide theoretical basis and data support for improving the properties of global terrestrial ecosystems by exploring the impact of mycorrhizal strategies on the stoichiometry of C, N, and P in different shrub organs. In this study, stoichiometric patterns of carbon (C), nitrogen (N) and phosphorus (P) in different shrub organs under different mycorrhizal status or types were analyzed at 725 samples across Northern China. Results showed that in different mycorrhizal status, the highest carbon concentration in shrub organs appeared in the facultatively mycorrhizal (FM) mycorrhizal status, and the highest nitrogen concentration appeared in the Non-mycorrhizal (NM) mycorrhizal status. Under different mycorrhizal types, the nitrogen concentration in the shrub organs under the arbuscular mycorrhiza (AM) mycorrhizal type was the highest, and the phosphorus concentration under the ecto-mycorrhiza (ECM) mycorrhizal type was the highest. In the OM or FM mycorrhizal status, the concentrations of C, N, and P in the stems and leaves increase with the increase of the concentrations of C, N, and P in the roots. In the NM mycorrhizal status, the N concentration in the stems and leaves increases with the increase of the N concentration in the roots. Under AM, AM+ECM, and ECM mycorrhizal type, the concentrations of C, N, and P are closely related in roots, stems and leaves. The content of plant nutrients in different organs is closely related. It turned out that mycorrhizal statuses or types are able to alter the allocation of C, N, and P in different organs, and the relationships of C, N, and P among different organs are able to present different trend with the varying of mycorrhizal statuses or types.

“…Болота, по сравнению с остальными типами растительности, характеризуются экстремальным переувлажнением и крайне бедным содержанием минеральных веществ. Это способствует формированию специфических по составу и структуре растительных сообществ [28]. В таких условиях влияние высоты расположения на функциональные характеристики сообщества минимизируется.…”

Grime’s CSR (competition-stress-ruderality) theory has found widespread use in modern ecology for the analysis of vegetation worldwide. This study aimed to verify if vegetation behavior predicted by this theory coincided with field observations along a highly pronounced altitudinal gradient and to determine if this behavior is the same for different vegetation types. We studied the 275 plots of different vegetation types in the Northern and Subpolar Urals (Russia). Based on the community-weighted mean approach, we allocated the CSR status of each plot. Then, we used generalized additive models and linear modeling to find relationships between CSR statuses, vegetation types and altitude. The plant communities were characterized by a predominance of species with competitor (C) and stress-tolerant (S) strategies and a small share of ruderal (R) species. According to the decrease in the share of competitors and the increase of stress-tolerators, the vegetation types were ranked as follows: forest (С: 47, S: 44), meadow (С: 47, S: 37), bush (С: 44, S: 46), mire (С: 42, S: 49) and mountain tundra (С: 35, S: 58). The different vegetation types showed different responses to elevation changes in the CSR terms. Meadows, bushes and mountain tundra showed the most corresponding behavior with Grime’s CSR theory predictions: a significant decrease of the C scores and an increase of S component (4–5% for every 100 m increase in elevation). Finally, forests and mires did not show notable changes in the CSR status.

Senesced leaves play a vital role in nutrient cycles in the terrestrial ecosystem. The carbon (C), nitrogen (N) and phosphorus (P) stoichiometries in senesced leaves have been reported, which are influenced by biotic and abiotic factors, such as climate variables and plant functional groups. It is well known that mycorrhizal types are one of the most important functional characteristics of plants that affect leaf C:N:P stoichiometry. While green leaves’ traits have been widely reported based on the different mycorrhiza types, the senesced leaves’ C:N:P stoichiometries among mycorrhizal types are rarely investigated. Here, the patterns in senesced leaves’ C:N:P stoichiometry among plants associated with arbuscular mycorrhizal (AM), ectomycorrhizal (ECM), or AM + ECM fungi were explored. Overall, the senesced leaves’ C, with 446.8 mg/g in AM plants, was significantly lower than that in AM + ECM and ECM species, being 493.1 and 501.4 mg/g, respectively, which was mainly caused by boreal biomes. The 8.9 mg/g senesced leaves’ N in ECM plants was significantly lower than in AM (10.4 mg/g) or AM + ECM taxa (10.9 mg/g). Meanwhile, the senesced leaves’ P presented no difference in plant associations with AM, AM + ECM and ECM. The senesced leaves’ C and N presented contrary trends with the changes in mean annual temperature (MAT) and mean annual precipitation (MAP) in ECM or AM + ECM plants. The differences in senesced leaves’ C and N may be more easily influenced by the plant mycorrhizal types, but not P and stoichiometric ratios of C, N and P. Our results suggest that senesced leaves’ C:N:P stoichiometries depend on mycorrhizal types, which supports the hypothesis that mycorrhizal type is linked to the evolution of carbon–nutrient cycle interactions in the ecosystem.
