    Agriculture ecosystems and environment (Elsevier, 2026)
    Plants shape soil microbiomes, yet this interaction is underexplored in the cultivated farmlands of the boreal region. We assessed the soil microbiome of seven differently managed major crop types in the region (pasture, ley, oat, rye, faba bean, oilseed, and cabbage), alongside a long-term environmental fallow, in 73 fields in Southern Finland. Microbial data were cross-analyzed with plant community data, which combined the cultivated and other vascular plants observed in the fields. Amplicon sequence analysis indicated that crop type, plant richness, plant coverage, and agricultural management affect the soil microbiome’s taxonomic and predicted functional composition. The most dissimilar microbial communities were under fallow and cabbage, which represented the management and plant diversity extremes. Plant richness influenced the community composition and predicted functional potential of bacteria and fungi. Microbial diversity was a poor indicator of the putative beneficial fungal functional group, arbuscular mycorrhizal fungi (AMF), and of bacterial predicted genes related to soil ecosystem functions, inorganic-phosphorus (Pi) solubilizing and nitrogen-fixing genes. Fallow with lowered microbial diversity had the highest proportions of nitrogen-fixing and Pi solubilizing genes, and AMF. Similarly, organic production method with lowered fungal richness in perennial crop types (pasture and ley) had high proportion of AMF and nitrogen-fixing genes across crop types. Tillage intensity was positively associated with the proportion of bacterial beta-glucosidase genes involved in carbon cycling. We show that in the boreal region, crop type and plant community (especially richness), and agricultural management all affect soil microbial communities, with potential implications for microbial-mediated soil functions.

    Effective management of marine ecosystems requires understanding linkages between biodiversity and ecosystem functioning. While key species have been identified in many marine systems, the functions provided by different habitats have not been comprehensively synthesised in the region, limiting the ability to identify key habitats. Here, we assess the current state of knowledge on biodiversity and ecosystem functions associated with benthic and pelagic habitat types in the northern Baltic Sea. Drawing on literature, data and expert assessments, we evaluated 49 habitat types, identifying 750 habitat type-function linkages. Of these, 35% were supported by Baltic Sea literature and 29% by expert opinion, while one-third remained unassessed due to data gaps. Our findings highlight key habitat types with high functional importance and reveal major knowledge gaps and research biases across habitats. This synthesis provides a science-based foundation for marine spatial planning, ecosystem service assessment, and sustainable management of northern Baltic Sea biodiversity.
  • An online tomographic sediment trap for high-resolution environmental monitoring

    Environmental monitoring and assessment : 6 (Springer Nature, 2026)
    Sediment trapping is a well-established method for obtaining information on sedimentation flux and composition in aquatic environments. Passive sediment traps typically have a collection period of several months to a year, while autonomous traps with revolving wheels can achieve a daily time resolution. However, these devices are often costly, require laborious maintenance, and have high power consumption, which limits their use in remote field locations. This study presents a novel, ultra-high-resolution (hourly temporal resolution) sediment trap based on optical tomography that enables continuous online monitoring of sediment flux. Laboratory validation demonstrated a high volumetric calibration accuracy, with a mean measurement error of ± 0.6 mL (R2 = 0.99). We deployed a prototype in Savilahti Bay, Kuopio, to evaluate its ability to detect short-term sediment pulses caused by onshore construction work. The field results confirmed the method’s effectiveness and reliability in tracking highly dynamic flux variations, although image processing techniques require further development for extreme sedimentation rates. The autonomous, solar-powered system transmits data wirelessly, significantly reducing fieldwork requirements. This methodology provides a crucial tool for monitoring high-resolution sediment dynamics and remote study sites.
