A conceptual framework for assessing pathways towards climate neutrality and biodiversity conservation in a circular forest-based economy

This study presents a conceptual framework for assessing the sustainability of the forest-based economy and resulting synergies and trade-offs between forest harvest, carbon sequestration, and biodiversity conservation. The framework adopts a comprehensive systems approach to map economic activities and associated flows of resources and embodied environmental impacts along the value chain. It buil

Long-term follow-up after otitis media in childhood

Popular Abstract in Swedish Bakgrund: Öroninflammation är vanligt förekommande i barnaåren. De flesta barn har haft minst en episod med akut varig öroninflammation (AOM) och/eller en period med vätska i mellanörat (SOM) före skolstart. De flesta får enstaka episoder, frekvensen av AOM avtar i 2-års åldern och frekvensen av SOM avtar före skolstart. Efter en AOM episod är det vanligt att man under Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. Subjects and methods: Out of a birth cohort followed to the age of 3 years, 12 child

Secondary organic aerosol from VOC mixtures in an oxidation flow reactor

The atmospheric organic aerosol is a tremendously complex system in terms of chemical content. Models generally treat the mixtures as ideal, something which has been questioned owing to model-measurement discrepancies. We used an oxidation flow reactor to produce secondary organic aerosol (SOA) mixtures containing oxidation products of biogenic (α-pinene, myrcene and isoprene) and anthropogenic (m

Biodiversity decline with increasing crop productivity in agricultural fields revealed by satellite remote sensing

Increasing land-use intensity is a main driver of biodiversity loss in farmland, but measuring proxies for land-use intensity across entire landscapes is challenging. Here, we develop a novel method for the assessment of the impact of land-use intensity on biodiversity in agricultural landscapes using remote sensing parameters derived from the Sentinel-2 satellites. We link crop phenology and prod

Temporal patterns in ecosystem services research : A review and three recommendations

Temporal aspects of ecosystem services have gained surprisingly little attention given that ecosystem service flows are not static but change over time. We present the first systematic review to describe and establish how studies have assessed temporal patterns in supply and demand of ecosystem services. 295 studies, 2% of all studies engaging with the ecosystem service concept, considered changes

Stratification strength and light climate explain variation in chlorophyll a at the continental scale in a European multilake survey in a heatwave summer

To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across the Mediterranean, Continental, and Boreal climatic zones of the European continent. Multilinear regression models tested on this snapshot of mostly eutrophic lakes (median total phosphorus [TP] = 0.06 and total nitrogen [TN] = 0.7 mg L−1), and its subsets (2

Mapping two centuries of forest governance in Nordic countries : An open access database

Forest ecosystems play a crucial role in the production and protection of economic, social, and environmental values. To understand current challenges and trajectories shaping future strategies within the Nordic forest sector, it is important to map and trace past and present policy and governance developments. The core contribution of this short communication is to present an open-access database

Influence of land cover on noise simulation output – A case study in Malmö, Sweden

Determining the land cover (LC) data requirements used as input to noise simulations is essential for planning sustainable urban densifications. This study examines how different LC datasets influence simulated environmental noise levels of road traffic using Nord2000 in an urban area of 1 km2 in southern Sweden. Four LC datasets were used. The first dataset was based on satellite data (spatial re

Spatial heterogeneity of soil carbon exchanges and their drivers in a boreal forest

Boreal forests have a large impact on the global greenhouse gas balance and their soils constitute an important carbon (C) reservoir. Mature boreal forests are typically a net CO2 sink, but there are also examples of boreal forests that are persistent CO2 sources. The reasons remain often unknown, presumably due to a lack of understanding of how biotic and abiotic drivers interact to determine the

Shifts in Microbial Thermal Traits Mitigate Heat-Induced Carbon Losses in Soils

Global warming is expected to transfer carbon from soil organic matter to atmospheric CO 2, with microbial communities playing a crucial role in regulating this exchange. While the immediate impact of temperature on microbial functions is well understood and causes soil carbon losses, the long-term response remains unclear, with losses stabilising over time, reducing the overall effect of chronic

BVOC and speciated monoterpene concentrations and fluxes at a Scandinavian boreal forest

Boreal forests emit terpenoid biogenic volatile organic compounds (BVOCs) that significantly affect atmospheric chemistry. Our understanding of the variation of BVOC species emitted from boreal ecosystems is based on relatively few datasets, especially at the ecosystem-level. We conducted measurements to obtain BVOC flux observations above the boreal forest at the ICOS (Integrated Carbon Observati

Modelling natural pest control across the world’s agroecosystems – an archetype approach

Control of crop pests by shifting host plant availability and natural enemy activity at landscape scales has great potential to enhance the sustainability of agriculture. However, mainstreaming natural pest control requires improved understanding of how its benefits can be realized across a variety of agroecologies. Empirical studies suggest significant but highly variable responses of natural pes

Climate change and ecological intensification of agriculture in sub-Saharan Africa : A systems approach to predict maize yield under push-pull technology

Assessing effects of climate change on agricultural systems and the potential for ecological intensification to increase food security in developing countries is essential to guide management, policy-making and future research. ‘Push-pull’ technology (PPT) is a poly-cropping design developed in eastern Africa that utilizes plant chemicals to mediate plant–insect interactions. PPT application yield

Semi-continuous C supply reveals that priming due to N-mining is driven by microbial growth demands in temperate forest plantations

Nitrogen (N) availability is a powerful controller of soil carbon (C) cycling in temperate forests, affecting plant productivity and microbial activities. Enhanced rhizosphere input from increased plant productivity can stimulate the decomposition of native soil organic matter (SOM), termed the “priming effect”, with an effect size that is affected by N availability. Using soils from N-fertilizati

The interaction between companies internal processes and the service encounter and its affect on the perceived quality A case study in the automotive industry

The competition in the automotive industry is constantly increasing and it is no longer sufficient for a company to only deliver a physical product. The companies’ ability to fill a need and provide a solution including a combination of both tangible and intangible products is becoming increasingly important. The service a company offers can be a critical factor for success why a company needs to

Investigation of dissolution properties of Cd(OH)2 in alkaline solution

De nickel-kadmiumbatterier som tillverkas vid Saft AB i Oskarshamn är uppladdningsbara och används vanligen som backup för strömförsörjning på sjukhus, flygplatser och till och med för hela städer. Ett problem för nickel-kadmiumbatterier är upplösning av kadmiumhydroxid, det aktiva materialet i kadmiumelektroden. Utöver förlust av aktivt material kan det upplösta materialet bilda ett tunt lager påIn this project, the properties of Cd(OH)2 in alkaline solution were studied. The processes of oxidation and reduction for Cd(OH)2 in alkaline solution are very complex and even though many studies have been done on the subject, it is not completely understood yet. It is from a Ni-Cd battery point of view, important to understand these processes to prevent loss of active material. The Cd-electrode

Towards a remote-sensing-driven model of isoprene emissions from Alpine tundra

This study investigates isoprene emissions in a high-latitude Alpine tundra ecosystem, focusing on using near-field remote sensing of surface temperatures, the photochemical reflectance index (PRI) and normalized difference vegetation index (NDVI), and meteorological measurements to model these emissions. Isoprene is a key biogenic volatile organic compound (BVOC) emitted by select plants, which c

Atmospheric and Deposition Responses of 10Be to Volcanic Eruptions Inferred From the Aerosol-Climate Model ECHAM6.3-HAM2.3-SALSA2.0 : 10Be

10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state-of-the-art aerosol-climate model ECHAM6.3-HAM2.3-SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance stratospheric 10Be sedimentation, increasing atmospher
