Aboveground organic matter removal reshapes soil microbial functional group balance in temperate forests

The growing demand for renewable materials and energy leads to intensified forest management practices. Therefore, combining high forest productivity and soil carbon storage capacity with lower quantities of organic matter (OM) left on the ground to decompose represents a major challenge. Although microbial communities drive processes responsible for organic carbon stabilization in soil, we have l

Functional genomics gives new insights into the ectomycorrhizal degradation of chitin

Ectomycorrhizal (EcM) fungi play a crucial role in the mineral nitrogen (N) nutrition of their host trees. While it has been proposed that several EcM species also mobilize organic N, studies reporting the EcM ability to degrade N-containing polymers, such as chitin, remain scarce. Here, we assessed the capacity of a representative collection of 16 EcM species to acquire 15N from 15N-chitin. In ad

Fungal communities mediate but do not control leaf litter chemical transformation in a temperate oak forest

Background and Aims: In temperate forests, fungi are the main actors in leaf litter decomposition. Still, we have minimal knowledge of their influence on changes in leaf litter chemistry. Thus, we aimed to determine the main drivers behind leaf litter chemical transformation during decomposition. Methods: We monitored the development of fungal communities, extracellular enzyme activities, and litt

Melanization slows the rapid movement of fungal necromass carbon and nitrogen into both bacterial and fungal decomposer communities and soils

Microbial necromass contributes significantly to both soil carbon (C) persistence and ecosystem nitrogen (N) availability, but quantitative estimates of C and N movement from necromass into soils and decomposer communities are lacking. Additionally, while melanin is known to slow fungal necromass decomposition, how it influences microbial C and N acquisition as well as elemental release into soils

Microbial community attributes supersede plant and soil parameters in predicting fungal necromass decomposition rates in a 12-tree species common garden experiment

Although dead fungal mycelium (necromass) represents a key component of biogeochemical cycling in all terrestrial ecosystems, how different ecological factors interact to control necromass decomposition rates remains poorly understood. This study assessed how edaphic parameters, plant traits, and soil microbial community structure predicted the mass loss rates of different fungal necromasses withi

Primer pairs, PCR conditions, and peptide nucleic acid clamps affect fungal diversity assessment from plant root tissues

High-throughput sequencing has become a prominent tool to assess plant-associated microbial diversity. Still, some technical challenges remain in characterising these communities, notably due to plant and fungal DNA co-amplification. Fungal-specific primers, Peptide Nucleic Acid (PNA) clamps, or adjusting PCR conditions are approaches to limit plant DNA contamination. However, a systematic compari

Differential effects of tree species identity on rhizospheric bacterial and fungal community richness and composition across multiple trace element-contaminated sites

Soil microbial communities play a key role in plant nutrition and stress tolerance. This is particularly true in sites contaminated by trace metals, which often have low fertility and stressful conditions for woody plants in particular. However, we have limited knowledge of the abiotic and biotic factors affecting the richness and composition of microbial communities inhabiting the rhizosphere of

The Multi-Scalar Inequities of Climate Adaptation Finance : A Critical Review

Purpose of Review: Following a multi-scalar analytical approach, this critical literature review explores the factors that determine adaptation finance accessibility and allocation with particular attention to how the needs of climate-vulnerable communities are considered. Recent Findings: Our review reveals that climate vulnerability is not a primary determinant in the accessibility and allocatio

Economic research emphasises the role of increasing returns to scale and critical mass in research and technology development. This suggests that countries benefit from specialising in certain technologies and can thereby bundle available resources. Using the example of the Exzellenzstrategie and the Zukunftsstrategie, we argue that German RTI policy lacks strategic prioritisation. The lack of foc

Sensitization to molecular dog allergens in an adult population : Results from the West Sweden Asthma Study

Background: As the prevalence of dog allergy rises, component resolved diagnosis might improve the diagnosis, understanding of the clinical outcomes and the effectiveness of immunotherapy. Considering the paucity of data in adults, the current study characterized the patterns of sensitization to dog molecular allergens in an adult population. Methods: Data were derived from the West Sweden Asthma

Sensitization patterns to cat molecular allergens in subjects with allergic sensitization to cat dander

Background: The use of molecular allergology has increasingly become common in the diagnosis and management of allergic diseases. However, there is still a lack of data on cat molecular allergens in adults. Therefore, we aimed to uncover the sensitization patterns to cat molecular allergens. Methods: Participants were recruited from the West Asthma Sweden Study, a population-based study enriched w

Andexanet for Factor Xa Inhibitor-Associated Acute Intracerebral Hemorrhage

Background Patients with acute intracerebral hemorrhage who are receiving factor Xa inhibitors have a risk of hematoma expansion. The effect of andexanet alfa, an agent that reverses the effects of factor Xa inhibitors, on hematoma volume expansion has not been well studied. Methods We randomly assigned, in a 1:1 ratio, patients who had taken factor Xa inhibitors within 15 hours before having an a

Mortality, morbidity, and predictors of death among amphetamine-type stimulant users − a longitudinal, nationwide register study

Introduction: Use of amphetamine-type stimulants (ATS) contributes substantially to the global burden of disease. Large-scale follow-up studies of morbidity and mortality in ATS users are few. This study analysed morbidity, mortality, and potential predictors of all-cause mortality in a nationwide cohort of patients with ATS use disorder. Methods: Data was acquired from national Swedish registers.

Patient-reported Side Effects 1 Year After Radical Prostatectomy or Radiotherapy for Prostate Cancer : A Register-based Nationwide Study

BACKGROUND: Data on functional and psychological side effects following curative treatment for prostate cancer are lacking from large, contemporary, unselected, population-based cohorts. OBJECTIVE: To assess urinary symptoms, bowel disturbances, erectile dysfunction (ED), and quality of life (QoL) 12 mo after robot-assisted radical prostatectomy (RARP) and radiotherapy (RT) using patient-reported

Evolution of cosmic filaments in the MTNG simulation?

We present a study of the evolution of cosmic filaments across redshift with an emphasis on some important properties: filament lengths, growth rates, and radial profiles of galaxy densities. Following an observation-driven approach, we built cosmic filament catalogues at z = 0, 1, 2, 3, and 4 from the galaxy distributions of the large hydro-dynamical run of the MilleniumTNG project. We employed t

Further Interventions after Root Canal Treatment Are Most Common in Molars and Teeth Restored with Direct Restorations : A 10–11-Year Follow-Up of the Adult Swedish Population

Introduction: The aims were to investigate 1) the frequency of nonsurgical retreatment, root-end surgery, extraction, and further restorative treatment during a follow-up of 10–11 years after root filling and compare the frequencies according to tooth group and type of coronal restoration and 2) the timing of nonsurgical retreatment, root-end surgery, and extraction. Methods: Data were collected f

Optimization of coal desulfurization method by sub/supercritical fluid extraction with binary mixtures of carbon dioxide and ethyl lactate as a solvent

Coal combustion for energy results in the emission of air pollutants such as NOx and SOx, which negatively affect human health and the environment. Reducing toxic gas emissions and ash production is needed to achieve cleaner coal. This study aimed to develop an extraction method for desulfurizing coal with non-toxic solvents before combustion. Mixtures of sub/supercritical carbon dioxide and ethyl

Information sharing in extended supply chains : why does it have to be so difficult?

Theory and practice present opposing views on whether or not companies should strive for multi-tier information sharing (MTIS) in supply chains. The purpose of this study was to identify and explore factors that influence MTIS. We performed a longitudinal Delphi study with 29 supply chain experts, including in-depth interviews and quantitative as well as qualitative analyses. Twelve contextual fac
