Ecological stoichiometry assessment provides insight into the interactions between foliar-litter-soil dynamics among dominant tree species and facilitates their conservation. However, little research has been carried out on such trends within mixed forest ecosystems in national nature reserves globally. The present study fills this knowledge gap by examining ecological of at various altitudes desirable southern China. This concentrates six representative plant communities, each pivotal maintaining carbon (C), nitrogen (N), phosphorus (P), potassium (K) balances, along with energy flows. selected communities encompass two plantations comprising Cunninghamia lanceolata Phyllostachys edulis four natural forests, including evergreen broad-leaved (Manglietia conifera), deciduous (Daphniphyllum macropodum Acer davidii), consisting Fagus longipetiolata, coniferous (Tsuga chinensis). Furthermore, involved measurement C, N, P, K contents foliage, litter, soil. outcomes revealed significant variations foliar, soil stoichiometric attributes across communities. Correlation analysis highlighted substantial positive associations N P foliar litter components, while exhibited insignificance. Broad-leaved forests generally displayed higher leaf compared to forests. exceptions observed content M. conifera D. F. longipetiolata. high-altitude T. chinensis one highest ratios. Notably, demonstrated richness but deficiency K, impacting growth limiting availability. Additionally, low hindered decomposition. nutrient ratios other nutrients remained relatively stable except for C: which were consistent homeostasis theory.

Plant–soil feedback (PSF) was initially developed in the field of agricultural practices. In recent years, PSF has been extended to various ecosystems. Root exudates, essential for exchange materials, energy, and information at plant–soil interface, significantly influence PSF. However, how is driven by root secretions role these different pathways still needs be further explored, particularly forest Soil nutrients, microbial communities, nematodes are important research topics process exudates. Investigating aspects exudates provides valuable insights into complex interactions both above ground below surface. This can offer theoretical support guidance building stable, healthy, sustainable ecosystems future.

Introduction Cultivation of Chinese fir ( Cunninghamia lanceolata ) have alleviated timber shortages and mixed stands with indigenous species represent a sustainable forestry model. Studying system nutrient balance tree homeostasis can provide insights into the ecological advantages guide management plantations. Methods Mixed plantations two native broadleaf (Michelia macclurei Mytilaria laosensis) pure were examined for our study. The responses in carbon (C), nitrogen (N), phosphorus (P) distribution their stoichiometric characterization tree–litter–soil to stand changes evaluated. In addition, leaves, branches, trunks, bark roots was used measure trees’ adaptive capacity changes. Results results showed that Michelia significantly increased soil OC, TN, TP, improved sequestration storage functions litter mass C:N C:P different degrees. N P imbalance reduced leaf N:P, resulting limitation trees, while principal component analysis improvement TN plantation limitation. N, P, N:P branch, trunk, some whereas flexibility homeostasis.

Background Ecological stoichiometric characteristics of carbon (C), nitrogen (N), phosphorus (P), and potassium (K) serve as crucial indicators nutrient cycling limitation in terrestrial ecosystems. However, our current understanding subtropical forests their response to different climate conditions is still limited. Methods We selected six altitudes ranging from 700 m 1,200 simulate an evergreen broadleaf forest Wuyi Mountain, Fujian Province, China. investigated C, N, P, K stoichiometry homeostasis the green leaves, newly senesced leaf litter (fresh litter), soil this forest. Results Leaf P levels showed a decline with increasing altitude. Notably, ratios components exhibited bimodal distribution along altitudinal gradient. Additionally, trend N resorption efficiencies was observed altitude increased. Moreover, weak leaves. These findings highlighted significant impact on This study also contributed mechanism plant growth strategies under conditions.

Cellulose and lignin are the principal constituents of plant litter, their degradation plays an important role in maintaining soil carbon balance terrestrial ecosystems. Yet, our knowledge responses litter mass loss cellulose to quality, environmental factors, taxonomic diversity indices along elevational gradient subtropical forests remains sparse. To gain insight into decomposition dynamics its influencing we investigated foliar that from two most dominant tree species (900–1,600 m) a forest on Daiyun Mountain, China. Our results showed following. (1) The rate was higher than for collected at each elevation. different elevations greater early period (0–180 days) later (180–270 days). (2) Litter as well factors indices, together influenced addition rates degradation. key included air temperature, which had significant correlations with positively. namely is N (nitrogen) P (phosphorus) contents, positive vice versa lignin/N C/N ratios.

The ecological stoichiometric characterization of plant and soil elements is essential for understanding the biogeochemical cycles ecosystems. Based on three forest ages Pinus taiwanensis Hayata (P. taiwanensis) plantations in Gujingyuan National Nature Reserve (i.e., young (16 years), middle-aged (32 mature forests (50 years)), we conducted a field experiment to analyzed C, N, P stoichiometry relationships between needles, litter, soil, micro-organisms P. plantations. We intended elucidate nutritional characteristics stability mechanisms artificial ecosystem. results showed that C contents live leaf plantation were 504.17–547.05, 527.25–548.84, 23.40–35.85, 0.33–0.54 g/kg, respectively; respective N 11.02–13.35, 10.71–11.76, 1.42–2.56, 0.08–0.12 g/kg; 0.82–0.91, 0.60–0.74, 0.19–0.36, 0.03–0.06 g/kg. Forest age significantly influenced both as well (p < 0.05). Furthermore, although litter N:P content was comparable ratios C:N C:P notably higher compared those needles.
