Wildfires are a natural disturbance shaping boreal forests, but their effects on soil microbial communities and biogeochemical cycling remain unclear, particularly in Fennoscandia. We investigated the impact of fire severity and post-fire management on the soil microbial community two years after a boreal wildfire in Sweden. We quantified growth rates of bacteria, saprotrophic fungi (SF), ectomyco

Ideally a flux tower should be installed on a homogeneous and flat terrain. The surface should be physically homogeneous (same forest height and thermal properties) as well as be covered by same tree species, or in the case of the mixed forest, the distribution of the different species should be even (“well-mixed”). The fetch, the outreach of the homogeneous surface, should be longer than the exte

Critical infrastructure networks are susceptible to disruptions, and an imbalanced distribution of component importance can significantly amplify their vulnerability to cascading failures or targeted attacks. This study introduces a novel bi-objective optimization framework designed to enhance network resilience by strategically balancing component importance in multi-commodity spatial networks. T

Spatial compositional data with exact zeros arise in many applicationsbut remain challenging for models that often assume strictly positivecomponents. We develop a Bayesian spatial model that combines theDirichlet Composition Distribution, which accommodates exact zeros throughcomponent-specific zero probabilities, with a Gaussian Markov random field representationof the latent compositional field

Climate change is intensifying short-duration rainfall extremes, increasing urban pluvial flood risk across Swedish municipalities. This study develops a novel spatial statistical framework for basement flood risk assessment using Log-Gaussian Cox Process (LGCP) models on metric graphs, applied to 17 years of flood records from Trelleborg, southern Sweden.Unlike conventional approaches that treat

Inclination-dependent grain boundary (GB) energy and shear-coupled motion are studied for and tilt GBs in face-centered cubic materials using three-dimensional (3D) phase field crystal (PFC) simulations. A large dataset spanning misorientation and inclination space is systematically generated to evaluate trends in GB energy and shear-coupling. GB energy variations broadly follow ideal faceting a

Urban pluvial flooding is a growing climate-related risk in Nordic cities, where short-duration rainfall extremes interact with aging drainage infrastructure and urban form. This study analyses 17 years (2006–2023) of property-level basement flooding reports from Trelleborg, a coastal municipality in southern Sweden, to identify empirical rainfall thresholds and infrastructural conditions associat

Reconstructions and simulations disagree on whether the Holocene exhibited a long-term cooling or warming signal. Anthropogenic land-use could be an important forcing regionally, but available population-based estimates differ widely. We examine transient Holocene climate model simulations forced with three population-based disturbed-land reconstructions and compare this with a fourth scenario der

Foraminifera are single-celled eukaryotes; most possess a perforated calcite test (shell) that fossilizes in marine sediments. During calcification, morphological features reflect environmental conditions, particularly, foraminiferal porosity is a promising proxy for reconstructing past ocean oxygenation.However, traditional analysis relies on averages from small parts of the shell in 2D slices du

Nanoplastics are increasingly being recognized as a global pollutant. However, relatively few studies report directly measured concentrations of nano- and microplastics in environmental samples, although available data suggest levels of up to 0.5 mg L−1 in lake water, which is surprisingly high. Their degradation in the environment, particularly under UV irradiation, is still poorly understood. He

We must recognize that plastics likely constitute a pervasive background in many environments. Beyond their previously documented risks to ecosystems and human health, plastics may also exert unintended influences on laboratory experiments, potentially distorting experimental outcomes. Here, we demonstrate that ultrasound treatment of commonly used laboratory test tubes releases nanoplastics into

This book proposes the study of norms as a method of explaining human choice and behaviour by introducing a new scientific perspective.The science of norms may here be broadly understood as a social science which includes elements from both the behavioural and legal sciences. It is given that a science of norms is not normative in the sense of prescribing what is right or wrong in various situatio

The study was a non-randomized controlled phase I-II trial to study were to ascertain the safety, feasibility and efficacy of immunotherapy with autologous IFN-γ transfected tumour cells in patients with glioblastoma multiforme. Autologous tumour cells harvested during surgery were cultured and transduced with the human IFN-γ gene. Irradiated cells were administered as intradermal immunizations ev

Our societies are ageing, and an urban-regional perspective on these developments is urgently needed. This figure shows an uneven geography of population ageing in Sweden—in the level and pace of ageing—and calls for variegated societal adaptations across municipalities.
