However, the specific roles of these two hypotheses and their environmental preferences on soil bacterial and fungal communities are not fully understood. By conducting two independent experiments (a 16-year N and a 6-year acid addition) in a temperate semi-arid grassland, we tested the responses of soil microbial attributes (e.g., richness and relative abundance) at various levels (community, phylum/class, and phylotype) to N and acid addition. At the community level, our results showed that both N and acid addition had a negative effect on the richness of the whole, dominant, and rare bacterial communities; N enrichment only decreased the richness of the dominant fungal community, while acid addition decreased the richness of the whole, dominant, and rare fungal communities. By categorizing the microbial attributes into nine environmental preferences based on their responses to N and acid addition, we found that most bacterial phyla were associated with low N availability and high pH preferences, while most fungal classes had other environmental preferences. Most dominant bacterial phylotypes were linked to low N availability and high pH preferences, while most dominant fungal phylotypes were associated with other environmental preferences and high pH preferences. Conversely, most rare bacterial and fungal phylotypes were linked to other environmental preferences. Our experiments revealed that the decline in bacterial richness caused by N enrichment was predominantly due to their sensitivity to soil acidification, while fungal richness remained largely unaltered. By pinpointing distinct microbial attributes at different levels in response to N and acid addition, our findings could potentially forecast how soil microorganisms will react to future global N deposition.</p></div>","PeriodicalId":21888,"journal":{"name":"Soil Biology & Biochemistry","volume":"197 ","pages":"Article 109541"},"PeriodicalIF":9.8,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141892069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exploring the impacts of nitrogen (N) and phosphorus (P) deposition on earthworm communities is significant for understanding the contributions of tropical forests to global change. A 14-year field experiment simulating N and P deposition at a station with 50-year-old tropical plantations was conducted. We found that the pantropical widespread exotic earthworm species <em>Pontoscolex corethrurus</em> was dominant, and it did not respond to exogenous N input. Moreover, P addition only increased the abundance of <em>P. corethrurus</em> after 14 years. Similarly, neither N addition nor P addition changed the stoichiometric traits of <em>P. corethrurus.</em> However, over the past decade, the abundance, biomass, and carbon (C), N, and P concentrations in the tissues of <em>P. corethrurus</em> have increased. A strong positive correlation between <em>P. corethrurus</em> population size and soil gram-negative (G⁻) bacteria biomass was observed, suggesting that <em>P. corethrurus</em> may benefit from the soil bacterial channel. This study ascertained that non-natural tropical lands may be resistant to N and P deposition in terms of earthworm related belowground processes, which would be helpful for fully understanding plant-soil biota feedback and their contributions to tropical plantation development and the mitigation of global climate change.</p></div>","PeriodicalId":21888,"journal":{"name":"Soil Biology & Biochemistry","volume":"197 ","pages":"Article 109540"},"PeriodicalIF":9.8,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141892070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This shift can alter microbial community composition and activity in these ecosystems. In this study, we aimed to identify genes transcribed by active microorganisms and compare their expression in unamended and amended soils with labile carbon and/or nitrogen compounds. We also assessed gene expression differences in tundra soils with varying edaphic characteristics (upslope vs. downslope sites). We amended soils with either glycine or cellulose or left them unamended (i.e., control) for 7 days of incubation, and we isolated and sequenced RNA using Illumina technology. Whereas we observed only a weak transcriptional response after cellulose addition, the glycine addition significantly influenced transcriptional patterns, with upregulation of carbon- and nitrogen-cycling genes. Notably, microbial taxa from the Pseudomonadaceae and Micrococcaceae families showed the most pronounced response to glycine, indicating a shift of the communities towards copiotrophic organisms. This response was consistent across the two soil types, suggesting a common impact on microbial community activity. These findings suggest that an increase in carbon and nitrogen inputs could substantially affect microbial functioning in High-Arctic tundra soils, with potential implications for ecosystem dynamics under global warming.</p></div>","PeriodicalId":21888,"journal":{"name":"Soil Biology & Biochemistry","volume":"197 ","pages":"Article 109539"},"PeriodicalIF":9.8,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0038071724002281/pdfft?md5=7caeaab2c0770e7e3618e68fd4298b07&pid=1-s2.0-S0038071724002281-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141892071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is believed that this constraint may be mitigated if trees under elevated CO₂ (eCO₂) prime microbial activity in their rhizosphere to release available N. We assessed whether mature trees under eCO₂ regulate N availability in their rhizosphere to meet increased N demand. We hypothesized that eCO₂ primes N mineralization in the rhizosphere while reducing N losses through nitrification and denitrification. This study was conducted in a mature English-Oak-dominated temperate forest in central England, in the sixth year of Free Air CO₂ Enrichment (FACE). In the summer of 2022, we measured N transformations, enzyme activities, and nutrient pools in the rhizosphere and bulk soil of the organic layer (0–7 cm) under laboratory conditions. While the rhizosphere was found to be inherently more active (i.e. positive N priming) than the bulk soil, the effect of eCO₂ were not consistently stronger in the rhizosphere. Available soil N, dissolved organic carbon and microbial biomass were enhanced under eCO₂ in bulk and rhizosphere soils. Net N mineralization was enhanced under eCO₂ in the bulk and rhizosphere soils while leucine aminopeptidase activity, associated with organic N depolymerization, was enhanced solely in the rhizosphere. Despite higher C and N availability creating potential hot spots, nitrification was reduced under eCO₂ and denitrification remained unaffected in the rhizosphere, demonstrating a more efficient conservation of N under eCO₂. Our findings demonstrate that eCO₂ stimulates N-mining and reduce N losses in the rhizosphere. Furthermore, the tenfold difference in N turnover rates between rhizosphere and bulk soils suggests that expanding rhizosphere mass from increased root biomass may help trees under eCO₂ to meet higher N demand.</p></div>","PeriodicalId":21888,"journal":{"name":"Soil Biology & Biochemistry","volume":"197 ","pages":"Article 109537"},"PeriodicalIF":9.8,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0038071724002268/pdfft?md5=a590dcd39a2fbb17625ecf7c29caf5af&pid=1-s2.0-S0038071724002268-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141769240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how rainfall redistribution affects soil C mineralization (CO₂ and CH₄ fluxes) in humid regions such as of the coastal saltmarshes remain unclear. We conducted mesocosm experiments in an estuarine saltmarsh in the Yellow River Delta of China, where we simulated three rainfall frequency scenarios (high-frequency, medium-frequency and low-frequency) with the same total rainfall amount in the dry and wet seasons, respectively. Soil CO₂ and CH₄ fluxes were measured before and after rain frequency treatment during a 40-day period for each season. The decrease in rainfall frequency significantly reduced the mean soil CO₂ and CH₄ fluxes during the dry season, but had no effect on either flux during the wet season. The seasonal variation in the response of soil C mineralization to rainfall frequency changes could be explained by the changes in antecedent soil water and salinity conditions, soil C substrate, microbial activities and diversity. Thus, the effects of changes in rainfall frequency on soil C mineralization are regulated by season, and should be considered when predicting the future C balance of coastal wetland ecosystems. Furthermore, the shift in precipitation frequency distribution towards increasing heavy rainfall events during the dry season in this region will have a great effect on soil C losses, potentially feeding back into the soil C budget and stability in this estuarine saltmarsh.</p></div>","PeriodicalId":21888,"journal":{"name":"Soil Biology & Biochemistry","volume":"197 ","pages":"Article 109538"},"PeriodicalIF":9.8,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141769235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intact soil cores were sampled from lysimeters previously subjected to induced topsoil or subsoil compaction, as well as from uncompacted lysimeters. The soil cores were drained, sequentially, to −30, −50, and −100 h Pa to examine gas phase characteristics, each time followed by N₂O diffusion measurements after injecting N₂O at the bottom of the soil cores to simulate hotspots. Pore architecture was determined with X-ray microtomography. Results showed that soil compaction decreased pore volume, gas flow (convection and diffusion), and pore connectivity, and increased water-filled pore space, isolated pore ratios, and solid-to-pore distance, with a concomitant effect on N₂O diffusion. Changes in soil matric water potential did not influence the N₂O diffusion ratio (N₂O in the headspace/N₂O injected into the reservoir). The algorithmic evaluation of interacting effects revealed that pore connectivity was the best predictor for N₂O diffusion. In hierarchical order, the N₂O diffusion ratio could be explained by air permeability, pore connectivity and relative gas diffusivity. Multivariate analysis of functional and architectural pore characteristic parameters provided a comprehensive selection of factors driving N₂O diffusion within the soil layers.
