Phenotypic plasticity and local adaptation jointly shape plant responses to environmental variation, but their relative contributions and trait-specific interactions remain poorly understood. (1) We quantified metabolites and measured growth, reproduction and herbivore resistance-related traits in 15 Fragaria vesca genotypes from a European latitudinal gradient grown reciprocally in four common gardens over two years. (2) Environment explained most trait variance (30%), followed by genotype × environment interactions (18%) indicating evolved plasticity, then genotype (9%). (3) Northern genotypes exhibited greater plasticity in stress-related metabolites but more canalization in growth-related traits, while southern genotypes maintained constitutively high levels of protective metabolites; this resulted in latitude shaping more than 4% of plasticity profiles. (4) Long-term temperature at origin outperformed precipitation in predicting trait variation across all categories. Synthesis. Plasticity dominates over local adaptation along climate gradients but evolves in a trait-specific manner as a heritable target of selection, buffering populations against climate shifts while also shaping the pace of genetic tracking, critical for predicting range dynamics under climate change.

Evaluation of biochar-assisted contaminant immobilization as a soil remediation technology must consider the trade-off between the positive effects of reduced toxic impacts through soil cleanup and climate change mitigation through carbon storage, and the negative impacts associated with contaminants introduced to soil with the biochar. Addressing this trade-off is challenging, as existing models and characterization factors used in life cycle impact assessment (LCIA) are generally not representative of conditions at contaminated sites, particularly in the presence of sorbents such as biochar. In addition, comparative toxicity potentials (CTPs) of most per- and polyfluoroalkyl substances (PFAS) compounds are not available for soils. To address these challenges, we applied the USEtox framework to quantify environmental fate, ecosystem exposure, and ecotoxicological effects of perfluorooctanoic acid (PFOA) as the remediation target, and several metals and polycyclic aromatic hydrocarbons (PAHs) introduced via biochar amendment. The resulting CTPs were used in the LCIA phase of a life cycle assessment (LCA) of soil remediation based on the LC-Impact methodology. Biochar had a significant influence on the CTPs of PAHs, a moderate effect on PFOA, and a limited effect on metals. The trade-off between the immobilization of PFOA and the introduction of PAHs and metals was outweighed by the benefits of carbon storage and avoided incumbent waste management. These results suggest that the implementation of biochar-assisted remediation should be primarily guided by the carbon storage potential of the biochar and the characteristics of incumbent feedstock treatment pathways, whereas the effect of biochar on PFOA immobilization was less influential.

This data article presents a multi-source dataset of satellite-based auxiliary data designed for forest modelling and monitoring. The dataset integrates annual medoid composites derived from Sentinel-1, Sentinel-2, and Landsat imagery, together with spectral indices, Landsat-based 3I3D change metrics, forest mask and forest type layers, and terrain variables derived from the Copernicus GLO-30 DEM, offering comprehensive information on forest cover, spectral behavior, and change metrics. It provides harmonized predictors across seven European countries, ensuring consistency, scalability, and ease of use for researchers developing or validating models to understand forest dynamics and estimate forest-related variables such as biomass or canopy recovery. A curated subset of the dataset is distributed via Zenodo, along with direct public access links to the complete multi-terabyte archive. The data support applications in forest biodiversity conservation, carbon monitoring, biomass modelling, and climate-change impact assessment.

Ny forskning viser at gran fra Nordland og Troms tilfredsstiller kravene til konstruksjonsvirke når den styrkesorteres etter gjeldene regler. Skogen som ble plantet før og etter 1945 kan etter hvert avvirkes, og representerer en betydelig ressurs for bygg og rehabilitering. Utfordringen er ikke kvaliteten på råstoffet – men trolig manglende lokal foredling og bruk.

Overvåkingsprogrammet, som er finansiert av Mattilsynet, undersøkte i 2025 om karanteneskadegjøreren furuvednematode (Bursaphelenchus xylophilus) var til stede i hogstavfall fra furu eller i furubukker av slekten Monochamus, kjent som vektorer for B. xylophilus. I programmets delaktivitet som omfattet kartlegging av furuvednematode i hogstavfall ble det tatt 404 flisprøver fra hogstavfall og vindfall av furu (Pinus sylvestris) med tegn på angrep av furubukker i slekten Monochamus. Prøvene ble tatt i Akershus, Innlandet og Østfold. Flisprøvene ble inkubert ved 25 °C i to uker, før nematoder ble ekstrahert med Baermann-trakt og undersøkt i mikroskop. Furuvednematoden B. xylophilus ble ikke påvist, men den naturlig forekommende arten Bursaphelenchus mucronatus kolymensis ble oppdaget i åtte flisprøver. Siden overvåkingen av furuvednematode startet i 2000, har alle de 10 141 analyserte flisprøvene vært negative for furuvednematode. I programmets delaktivitet som omfattet kartlegging av furuvednematode i furubukker ble feller med kjemiske attraktanter for fangst av voksne, flygende furubukker satt opp nær vareimportsteder i Akershus, Oslo, Vestfold, Rogaland og Trøndelag. Ingen Monochamus-biller ble fanget, noe som kan tyde på at varer importert til de overvåkte importstedene ikke inneholdte levende Monochamus-biller. Fraværet av Monochamus-biller i fellene tyder også på at det var lite naturlig hjemmehørende Monochamus-biller i overvåkingsområdene.

Background: Pesticides are used in greenhouse cultivation to control fungi and pests and to shape plant growth. This influences microbial communities and may increase the selective pressure for resistant species development. Antimicrobial resistance (AMR) is a growing global health challenge, and while AMR dispersal through soil and water is well studied, the role of bioaerosols as AMR vectors remains insufficiently explored. Objectives: To explore the link between chemical pesticide and the prevalence of AMR genes in aerosols from greenhouses using pesticides and those not using them. Methods: Forty-nine fullshift personal samples of inhalable dust were collected in eight greenhouses from 2021 and 2024. Five greenhouses used chemical pesticides and three did not. DNA was extracted and screened for the presence of 45 clinically relevant AMR genes using HT-qPCR. Results: Twenty of the 45 screened genes were detected. Greenhouses using pesticides showed significantly higher AMR gene levels than those not using chemicals. Several genes, particularly β-lactam and tetracycline resistance genes, occurred in high concentrations, including extreme values exceeding 60,000 gene copies/m³. This suggest that pesticide-using greenhouses may represent a greater risk for AMR dispersal. In contrast, greenhouses without chemical pesticide showed lower and more stable AMR gene levels. Factors other than pesticide application may also contribute, such as import of treated plants, soil and fertilizer materials, plant types or individual workers. Further research is needed to assess the health risks for greenhouse workers and to support the development of effective strategies for preventing and controlling AMR spread.
