Microorganisms are vital in mediating the earth's biogeochemical cycles; yet, despite our rapidly increasing ability to explore complex environmental microbial communities, relationship between community structure and ecosystem processes remains poorly understood. Here, we address a fundamental unanswered question ecology: 'When do need understand accurately predict function?' We present statistical analysis investigating value of data independently combination for explaining rates carbon...
Pesticide residues in agricultural soils represent an environmental concern that requires special attention due to their potential ecological and public health risks. We analyzed 614 pesticides 188 wheat fields across Europe subjected both conventional organic farming systems. At least one pesticide residue was detected 141 soils. Seventy-eight or metabolites were detected. The presence of significantly higher number concentration fileds (up 0.98 mg kg-1) compared organically managed sites...
Fens, which extend over vast areas in the Northern hemisphere, are sources of greenhouse gas CH4. Climate change scenarios predict a lowering water table (WT) mires. To study effect WT drawdown on CH4 dynamics fen ecosystem, we took advantage gradient near ground extraction plant. Methane fluxes and production oxidation potentials were related to microbial communities responsible for processes four mire locations (wet, semiwet, semidry, dry). Principal component analyses performed...
Abstract. Peatlands are carbon (C) storage ecosystems sustained by a high water table (WT). High WT creates anoxic conditions that suppress the activity of aerobic decomposers and provide for peat accumulation. Peatland function can be dramatically affected drawdown caused climate and/or land-use change. Aerobic directly through environmental factors such as increased oxygenation nutrient availability. Additionally, they indirectly via changes in plant community composition litter quality....
Summary Microbial respiration in dead wood contributes substantially to the long‐lived forest carbon (C) pool and has a significant role nitrogen (N) cycle. Wood N content been found increase during decay process; however, temporal dynamics sources of this external remain unclear. To examine at various stages decomposition, we combined high variety analytical methods on Norway spruce logs, including δ 15 N, N%, 14 C‐dating, fungal composition 2 fixation rate. For rate, also determined its...
Abstract Globally 40–70 Pg of carbon (C) are stored in coarse woody debris on the forest floor. Climate change may reduce function this stock as a C sink future due to increasing temperature. However, current knowledge drivers wood decomposition is inadequate for detailed predictions. To define factors that control respiration rate Norway spruce and produce model adequately describes process species time, we used an unprecedentedly diverse analytical approach, which included measurements...
Long-term effects of organic and conventional farming systems in parallel on the microbiota boreal arable soil from forage cereal crop fields were investigated. Microbial activity was measured as basal respiration microbial biomass C N determined by fumigation extraction. abundance gene copy numbers bacterial archaeal specific 16S rRNA genes fungal ITS2 region with quantitative PCR. community composition for bacteria fungi, including arbuscular mycorrhiza, conducted amplicon sequencing...
Abstract Diversification of agricultural practices, including changes in crop rotation, intercropping or cover cropping, influence the soil microbiome. Here impact tillage and diversification on microbiome is reported, being one few boreal studies. The field experiment consisted four treatments with replications all having a short cereal rotation practice namely an oat ( Avena sativa ) – spring barley Hordeum vulgare wheat Triticum aestivum for past 10 years until 2018. During that period...
Fungi play a pivotal role as highly effective decomposers of plant residues and essential mycorrhizal symbionts, augmenting water nutrient uptake in plants contributing to diverse functions within agroecosystems. This study examined soil fungi 188 wheat fields across nine European pedoclimatic zones under both conventional organic farming systems, utilizing ITS1 amplicon sequencing. The investigation aimed quantify changes induced by the system their correlation with features climatic...
Impacts of warming with open-top chambers on microbial communities in wet conditions and resulting from moderate water-level drawdown (WLD) were studied across 0–50 cm depth northern southern boreal sedge fens. Warming alone decreased biomass especially the fen. Impact PLFA fungal ITS composition was more obvious fen linked to moisture regime sample depth. Fungal-specific increased surface peat drier layers below 10 after warming. OTUs representing Tomentella Lactarius observed Mortierella...
Short-term agronomic and environmental benefits are fundamental factors in encouraging farmers to use biochar on a broad scale. The short-term impacts of forest residue (BC) the productivity carbon (C) storage arable boreal clay soil were studied field experiment. In addition, rain simulations aggregate stability tests carried out investigate potential BC reduce nutrient export surface waters. A addition 30 t ha−1 increased test phosphorus decreased bulk density but did not significantly...
We assessed the soil carbon sequestration potential of various organic amendments agricultural, municipal and industrial origin applicability a model to simulate it. The chemical composition large number plant residues, manures, composts, digestates biochars was determined selected materials were incubated in assess their decomposition rates effects on microbial community structure. Decomposability strongly correlated with initial by water, ethanol acid extraction. Fresh decomposed fastest,...
Abstract Declining carbon (C) content in agricultural soils threatens soil fertility and makes prone to erosion, which could be rectified with organic amendments. In a 4‐yr field trial, we made single application of three different sludges from the pulp paper industry studied their effects on cereal yield, C content, fungal bacterial composition. laboratory rainfall simulations, also amendments susceptibility erosion nutrient mobilization clay‐textured by measuring quality percolation water...
Abstract. Boreal upland forests are generally considered methane (CH4) sinks due to the predominance of CH4 oxidizing bacteria over methanogenic archaea. However, boreal can temporarily act as sources during wet seasons or years. From a landscape perspective and in annual terms, this source be significant weather conditions may cause flooding, which last considerable proportion active season because often, forest coverage within typical catchment is much higher than that wetlands. Processes...
Intensified arable farming results in fewer functional groups of soil biota with decreased biodiversity. Organic slurry fertilization and long crop rotation cycles favors fauna diversity under tropical temperate conditions. Faunal responses to agricultural practices northern latitudes may, however, differ from those southern due different types, climatic conditions, intensity management. We investigated the abundance communities (nematodes, microarthropods, enchytraeids earthworms) a boreal...
Peatlands, especially fens, are known to emit methane. Reindeer (Rangifer tarandus) use mires mainly as spring and summer pastures. In this work we observed that adding reindeer droppings fen peat increased the potential methane production by 40%. This became apparent when originating from kept in pen or pasture winter were added methanogenic samples. The introduced Methanobacteriaceae (Methanobrevibacter; > 90% of mcrA MiSeq reads) peat, which was originally populated Methanosarcinaceae,...
Abstract Peatlands are carbon dioxide (CO 2 ) sinks that, in parallel, release methane (CH 4 ). The peatland (C) balance depends on the interplay of decomposer and CH -cycling microbes, vegetation, environmental conditions. These interactions susceptible to changes that occur along a successional gradient from vascular plant-dominated systems Sphagnum moss-dominated systems. Changes similar this succession predicted climate change. Here, we investigated how microbial plant communities...
