Our study examined the ecostoichiometric internal stability (EIS) of nutrients accumulation and, concomitantly identified the main resistant regulating substances and their contributions to stress resistance of reed (Gramineae) in arid desert areas. Plants (digging method) and soil samples (quartering method)) obtained from sand dune (SD), desert steppe (DP), interdune lowland (IL), saline meadow (SM) and wetland (W) habitats were brought back to the lab for nutrients analysis. Results indicated that soil nutrients differed obviously, while reed maintained relatively stable ratios of SiO₂:N, N:K, and P:K when the eco-environments changed in different habitats. Furthermore, reed exhibits common adaptive characteristics by mainly accumulating large amounts of SiO₂ (122.6–174.0 g/kg) and NO₃⁻ (166.1–216.6 g/kg), as well as moderate levels of soluble sugar (SS: 24.0–55.0 g/kg), which are mainly stored in leaves for stress resistance. The contribution of ions to stress resistance was 80.03%–91.15% (with SiO₂ and NO₃⁻ accounting for 54.91%–63.10%), whereas the contribution of solutes was only 8.85%–19.97% (with SS contributing to 5.14%–10.91%) in different habitats. These findings suggest that maintaining relatively high EIS, while still accumulating SiO₂ and NO₃⁻ as main physiological regulators might be an effective strategy for reed to positively respond to adverse habitats, which provide a strong theoretical basis and technical reference for searching useful methods for restoration and reconstruction of the degraded ecosystems in desert oasis regions.</div></div>","PeriodicalId":53163,"journal":{"name":"Research in Cold and Arid Regions","volume":"16 5","pages":"Pages 250-258"},"PeriodicalIF":0.7,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we selected four PGPR strains derived from indigenous halophytes based on their growth-promoting characteristics. These strains underwent further selection via a petri dish assay. Subsequently, the effects of the selected PGPR strains on alfalfa growth and soil fertility were rigorously examined through pot trials. The results demonstrated that <em>Bacillus filamentosus</em> HL3, <em>B. filamentosus</em> HL6, <em>Bacillus subtilis</em> subsp. <em>stercoris</em> HG12, and <em>Paenibacillus peoriae</em> HG24 significantly produced indole-3-acetic acid (IAA), solubilized phosphorus, and fixed nitrogen (except for <em>B. filamentosus</em> HL6, which did not significantly fix nitrogen). Compared to non-inoculated plants, <em>B. filamentosus</em> HL6 and <em>B. subtilis</em> subsp. <em>stercoris</em> HG12 significantly enhanced seed germination, root elongation, and seedling biomass in a 150 mmol/L NaCl saline solution.

Therefore, this study aims to analyse the temporal and spatial distribution patterns of desert ants and to determine the effects of precipitation and temperature variations on ant assemblages. To achieve this, we continuously monitored the monthly dynamics of ants at 72 uniform 8m×8m grid points in the Gobi Desert ecosystem of Northwest China from 2015 to 2020 using pitfall traps.

In 2020, monthly captures of <em>M. desertus</em> exhibited a bimodal pattern, peaking in November, whereas those of <em>C. aenescens</em> exhibited a unimodal pattern, peaking in June. Annual data revealed that population size was significantly positively correlated spatially at a distance of 24 m. Semi-variance analysis and Moran's <em>I</em> indicated that structural factors predominantly controlled the ant assemblages at a small scale from 2015 to 2020. Annual catches of desert ants tended to decrease with increasing annual precipitation, while an opposite trend was rising average annual temperatures. In conclusion, variations in annual and monthly precipitation and temperature influenced the temporal response patterns of desert ants, thereby altering their spatial assemblages.</div></div>","PeriodicalId":53163,"journal":{"name":"Research in Cold and Arid Regions","volume":"16 5","pages":"Pages 229-238"},"PeriodicalIF":0.7,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, we attempt to examine the new trends in Chinese farmers' income inequality and to understand its causes during this period. We observe that China's urban-rural income ratio has been shrinking and the urban-rural inequality has been decreasing from 2014 to 2021. The reduction in the Theil index indicates a decrease in the regional inequality of farmers' income as well, and the decline in inter-regional inequality among eight economic zones contributes about 80% to increased equality. These new trends are caused by the fact that, with the TPA, the incomes of rural residents especially that in destitute areas, grew faster than that of urban residents and farmers in prosperous areas. The higher share of non-agricultural industry and agricultural mechanization level have significant positive impact on regional equality of farmers' income, while urban-rural dual structure has significant negative inhibitory effects. The lowest farmers' income and the highest inequality in the Northwest, and the slowest growth in the Northeast deserve more attention in rural Revitalization. From these findings, we propose four policy implications that would be applied to improve Chinese farmers' income equality, govern relative poverty, and achieve common prosperity in the post-poverty era.</div></div>","PeriodicalId":53163,"journal":{"name":"Research in Cold and Arid Regions","volume":"16 4","pages":"Pages 201-213"},"PeriodicalIF":0.7,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142659598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
