Savannas are well known for providing a multitude of diverse ecosystem services; however, the impacts of tree thinning and fire frequency during the forest to savanna conversion on soil organic carbon concentration (SOCc) and mycorrhizal fungal biomass remain poorly understood. This study, part of a long-term research project established in 1983 in southeastern Oklahoma, USA, examines how managed landscapes and resultant vegetation cover (i.e., forests and savannas) influence soil carbon storage and fungal functional group dynamics. Our findings reveal that in the top 5 cm of soil, SOCc was driven by soil macroaggregate abundance in forests and pH in savannas, with SOCc 23 % higher in forests, compared to savannas. At greater depths, pseudo-effective cation exchange capacity influenced SOCc in both cover types, with no significant differences in SOCc. Biomass of fungal functional groups (arbuscular mycorrhizal or ectomycorrhizal/saprophytic), assessed via phospholipid fatty acid analysis (PLFA), were largely driven by fire return interval. Additionally, total fungal biomass was predicted by the cation exchange capacity of the soil, regardless of cover type. Furthermore, despite the shift from ectomycorrhizal/saprophytic to arbuscular mycorrhizal fungi with forest to savanna conversion, savannas did not exhibit higher carbon concentration in the soil. Overall, our findings suggest that in the forest-grassland ecotone of the south-central USA, maintaining and preserving historic savannas that provide important ecosystem services requires only a small compromise in terms of soil carbon storage across the landscape.</div></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":"114 ","pages":"Article 151110"},"PeriodicalIF":2.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145841924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major challenge of agroecology is to define new methods for managing agroecosystems that enable a sustainable soil use and the preservation of its biodiversity. Sowing flower strips is often promoted in agri-environmental schemes, but their effect on soil biodiversity has yet been poorly considered. In this study, we followed the Collembola assemblages in response to the establishment of perennial wild flower strips within eight arable fields over four years (2018–2022). Collembola were sampled in the fields before the installation of the flower strips, in 2018 (y + 0), and in 2019 (y + 1), 2021 (y + 3) and 2022 (y + 4). Soil samples were taken within, at 5 m and at 30 m from the flower strips. Our results showed that there were no significant differences between the collembolan assemblages depending on the sampling distances from the flower strips. However, the age of the flower strips had an effect on Collembola assemblages, with y + 1 showing the lowest Collembola density and diversity. The differentiation between Collembola assemblages occurred three years after the flower strips sowing and was maintained for up to four years. Collembola appear to respond to environmental changes caused by flower strips sowing, since response traits such as sensory organs, pigmentation and sexual reproduction were the most dominant.</div></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":"114 ","pages":"Article 151109"},"PeriodicalIF":2.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145754153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we examined how soil microbial CUE responded to N and P inputs along a soil profile (0–80 cm) in a subtropical forest, using a long-term simulated N and P deposition experiment. Our results demonstrated a consistent increase in microbial CUE with depth across all treatments. Specifically, N addition significantly enhanced CUE by 27 % and 10 % at the depth of 40–60 cm and 60–80 cm, respectively, relative to the non-N group (which controlled for P variation). Furthermore, when compared directly to control, N addition increased CUE by 12.7 % and 13.5 % at these depths.

Regression analyses revealed significant associations between microbial CUE and soil pH, dissolved organic C, dissolved organic N, and available P. Variance partitioning analysis further elucidated that microbial CUE was predominantly governed by the interplay of soil substrates (primarily carbon and nutrient availability) and microbial enzymatic activities in surface layers, and N input was a major environmental driver for CUE variation in deep soils.

We studied invertebrate diversity in the China Muerta National Reserve (38º S) eight years after a high-severity wildfire. The goal was to assess how community structure changed after different wildfire severities and their effect on litter decomposition. We used litterbags with two mesh sizes: 1 mm to prevent and 5 mm to allow invertebrate access. These were placed in areas affected by high- and low-severity wildfires, as well as an unburned control site. Significant declines in invertebrate richness, abundance, and diversity were seen in both high- and low-severity plots compared to the control plots. Control plots contained 2.2 and 1.9 times more taxonomic groups than high- and low-severity fire plots, respectively. Similar patterns were observed in abundance and diversity. Predators, omnivores, and phytophagous species were less abundant in burned plots. Although soil properties changed between burned and unburned plots, these changes were not significantly related to soil invertebrate composition and trophic groups. Wildfire significantly influenced the litter decomposition rate, with low-severity plots showing the slowest rates (0.041 year⁻¹), followed by high-severity plots (0.086 year-¹), and control plots (0.114 year⁻¹). Decomposition rates decreased even further in litter bags inaccessible to invertebrates.

This study investigated the impact of forest conversion on the taxonomic and functional diversity of oribatid mite communities across four ecosystem types: natural forest, cypress and eucalyptus plantations, and coffee farm—in the Taita Hills, Kenya. We analyzed abundance, species richness, diversity indices, community-weighted mean (CWM) traits, and their relationships with environmental variables.

Higher litter thickness and humidity supported greater diversity, whereas elevated temperature and soil pH reduced it.
