We found that Crop Agriculture respiration peaked in the first 24 h of the incubation, while Forest peaked during the second and third 24 h periods.

These specific proportional respiration intervals were crucial in successfully predicting Crop Agriculture, Forest and Pasture LUs using machine learning models, with accuracy equivalent to comprehensive soil physicochemical parameters. Wetland respiration profiles were inconsistent with minimal predictive power, likely due to high variability of mineral and carbon (C) content. While early (24 h) respiration was proportionally largest for managed soils, indicating the impact of management in increasing respiration, absolute total respiration over 72 h was largest for natural soils, indicating their likely larger putative contribution, per unit area, to the atmospheric C pool.

Enhancing structural complexity (ESC) has been proposed to counteract these effects, but its impact on soil properties remains insufficiently understood. Overall, we hypothesize that ESC enhances soil abiotic properties, their spatial variability, and microbial functioning, with effects modulated by environmental context and increasing over time. Data were collected from 148 patches (50 × 50 m) in eight beech forests across Germany. In half of the patches, structural complexity was enhanced by felling 30 % of the basal area of living trees through two spatial patterns—aggregated (one large gap) and distributed (small gaps)—combined with leaving or removing deadwood (stumps, logs, snags). The other half served as controls, representing managed, homogeneous production forests. Soil carbon (C) %, nitrogen (N) %, and C:N ratio increased near deadwood. Soil microbial biomass and activity were significantly affected in three of eight forest sites, effects ranging from −30 % to +62 %. Higher soil water content was associated with increased microbial biomass, and greater understorey biomass correlated with a lower microbial respiratory quotient. However, no temporal trends were observed over five years. Although soil properties showed resistance to structural interventions, site-specific effects underline the importance of soil moisture and the understorey vegetation for microbial functioning. Further research building on our results is needed to develop practical forest management strategies to clarify how structural complexity may support soil functioning and ecosystem resilience.</div></div>","PeriodicalId":8099,"journal":{"name":"Applied Soil Ecology","volume":"214 ","pages":"Article 106335"},"PeriodicalIF":4.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144686253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Citizen science offers a promising tool to help fill these gaps, engaging a wider audience in monitoring efforts and thus enhancing our understanding of earthworm ecology. However, a significant challenge arises as earthworms are difficult to identify to the species level in the field by non-experts, necessitating the use of morphotypes as taxonomic proxies. This study evaluates the reliability of earthworm classification into four earthworm morphotypes within the ‘500 ENI’ (Non-intended Effects) Monitoring Network in France. The network relies on annual sampling conducted in agricultural lands by non-specialist participants with subsequent identification verification by earthworm taxonomists. Analyzing &gt;48,000 individual earthworms collected over 950 plots, we calculated two indices: the misclassification rate (MR) and the undetected rate (UR) to assess the reliability of classification into earthworm morphotypes. The results indicated an average MR of 28 % and an average UR of 32 %, which both varied according to morphotypes. Endogeics had lower error rates compared to epigeics, anecics with a red anterior, and anecics with a black anterior. Our findings underscored the significant impact of sampler experience and earthworm community composition on the reliability of classification of individuals into morphotypes by citizens. The results highlight the critical need for enhanced support and guidance for participants with limited experience. Furthermore, we recommend providing additional training or resources to aid in morphotype classification, especially for earthworm communities exhibiting low abundance, low adult proportion, or low morphotype diversity. Encouraging participants to sample during periods favorable for detecting reliable total and adult abundances would also help optimize morphotype detection.</div></div>","PeriodicalId":8099,"journal":{"name":"Applied Soil Ecology","volume":"214 ","pages":"Article 106329"},"PeriodicalIF":4.8,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the successional dynamics of wood-inhabiting microbial communities across different decay stages and their responses to varying forest gap positions remain poorly understood. Here, we present results from a 6-year in-situ experiment using Minjiang fir (<em>Abies faxoniana</em>) logs across five decay classes (I–V, representing increasing levels of decay) placed in gap centers, gap edges and under a closed canopy on the eastern Tibetan Plateau, China. Using high-throughput sequencing coupled with FUNGuild and Functional Annotation of Prokaryotic Taxa (FAPROTAX) analyses, we identified a total of 6193 fungal and 10,530 bacterial operational taxonomic units (OTUs). Fungal diversity in decaying logs initially increased, peaking in class III (maximum increase: 64 %), before declining in later stages. In contrast, bacterial diversity increased continuously, reaching its highest levels in decay classes IV and V (maximum increase: 27 %). Both fungal and bacterial species richness in decaying logs were greater at the center of forest gaps than under the closed canopy. Highly decayed logs favored specific fungal functional groups, such as ectomycorrhizal and saprotrophic fungi. Bacterial functional groups associated with the carbon cycle peaked in highly decayed logs (class V), whereas those linked to the nitrogen cycle were more abundant under the closed canopy. The dominant phyla, genera, and functional groups of fungi and bacteria were primarily driven by changes in log water content mediated by forest gaps, and the resulting pH and nutrient dynamics, rather than by temperature. These results highlight the pivotal roles of decaying logs and forest gaps in shaping the structural and functional succession of microbial communities. Therefore, maintaining coarse woody debris across various decomposition stages, particularly advanced decay classes, along with moderate gap disturbance, promotes the conservation of wood-inhabiting microbial diversity in forest ecosystems. Our study provides in-depth insights into the positive effects of forest disturbances, which are essential for informing sustainable forest management practices and preserving ecosystem health.</div></div>","PeriodicalId":8099,"journal":{"name":"Applied Soil Ecology","volume":"213 ","pages":"Article 106316"},"PeriodicalIF":4.8,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
