Boreal forest ecosystems are predicted to experience more frequent summer droughts due to climate change, posing a threat to future forest health and carbon sequestration. Forestry is a regionally dominant land use where the managed secondary forests are typically even-aged forests with low structural and tree species diversity. It is not well known if managed secondary forests and unmanaged prima
Plastic film mulching (PFM) in the cropland may alter biophysical conditions for crop growth, which may not be accounted for in existing stomatal conductance models. This can affect the accuracy of carbon–nitrogen-water cycle simulations for the soil-crop systems and hamper our understanding of internal mechanisms that control plant leaf stomatal conductance (gsw). To evaluate the simulations of P
The upper elevational limits of vegetation growth in global high-mountains have been the focus for monitoring and assessment of climate change impacts on terrestrial ecosystems. However, existing studies have relied on field surveys that do not allow for large-scale analysis. Although remote sensing data have been used for local and regional monitoring of the vegetation upper boundaries, a global
The 2018–2019 Central European drought was probably the most extreme in Germany since the early sixteenth century. We assess the multiple consequences of the drought for natural systems, the economy and human health in the German part of the Elbe River basin, an area of 97,175 km2 including the cities of Berlin and Hamburg and contributing about 18% to the German GDP. We employ meteorological, hyd
The accurate estimation of soil carbon (C) pool and fluxes is a prerequisite to better understand the terrestrial C feedback to climate change. However, recent studies showed considerable uncertainties in soil C estimates. To provide a reliable C estimate in the grasslands of the Qinghai-Tibet Plateau (QTP), we calibrated key parameters in a process-based ecosystem model (the CENTURY model) throug
Avhandlingen är en studie av hur stöd och service organiseras kring fyra barn med funktionshinder och deras familjer. I denna service är normalt flera olika formella organisationer involverade, som barnhabilitering, förskola/skola/särskola, hjälpmedelscentral, assistentorganisationer, sjukvård m fl. Dessutom kan barnets och familjens situation vara komplicerad på många sätt. Själva funktionshindreThis study explores the organising of services for disabled children and their families in Sweden. It is based on 83 interviews with parents and involved staff surrounding four disabled children, with both physical and intellectual disabilities, and between two and nine years old. Further, 15 meetings between parents and staff were observed, primarily serving as background material. The service pr
Obesity is a key factor for cardiovascular diseases and complications. Obesity is associated with hypertension, dyslipidemia and type II diabetes, which are the major predictors of cardiovascular disease in the future. It predisposes for atrial fibrillation, heart failure, sudden cardiac death, renal disease and ischemic stroke that are the main causes of cardiovascular hospitalization and mortali
Many studies suggest that increased exposure to urban greenness is associated with better population health. Accessing nature can in some circumstances, however, be difficult, especially for individuals with mobility constraints. Therefore, a growing body of work is investigating the ways to replace the in vivo experience with forms of “virtual” contact, in order to provide these individuals with
Mervärdesskatt är en indirekt skatt som ger stora intäkter till staten. Företag lägger också mycket tid och resurser på att hantera den. Reglerna om mervärdesskatt består huvudsakligen av genomförande av de EU-rättsliga direktiv som finns inom området. Just det stora inflytandet av EU-rätten gör mervärdesskatten speciell och komplex.Mervärdesskatt i teori och tillämpning ger en introduktion i ämne
This chapter contains an outline of the Swedish social security system with a focus on sickness benefits in the social security and unemployment insurance. The Swedish legislator’s ambition has been to create parity between different forms of employment as well as between those who are self-employed and those who operate in different company structures. Legislative amendments in this area have mai
Denna studie har genomförts på Tetra Pak för att studera deformation i vätskekartong under vikning. När en förpackning formas i fyllmaskinerna viks kartongen enligt biglinjerna. Det finns ett stort intresse av att studera vikprocessen då den är avgörande för den slutgiltiga kvaliteten av förpackningen. Matematiska modeller används för att simulera kartong men dessa kräver verkliga mätningar och dThis study has been conducted at Tetra Pak to study deformation in liquid packaging paperboard during the folding process. When a package is formed in the filling machines, the paperboard is folded according to the crease lines. It is of great interest to study the folding process since it is crucial to the final quality of the package. Mathematical models are used for simulation of paperboard bu
Biodiversity offsets and habitat banking in municipal planning Biodiversity offsetting is used to prevent loss of natural capital in connection with new developments. Biodiversity offsetting, which is based on the polluter pay-principle, means that those who cause loss or damage to nature values such as species, habitats or ecosystem services should make up for it by creating or ensuring correspo
Aim: This study investigated how human activities and local environmental variables shape tree assemblages (species composition in a defined location), comparing their effects on edible and inedible tree species. Three hypotheses were tested: (1) Environmental filtering impacts spatial beta-diversity more than dispersal limitation; (2) human activities significantly influence regional tree beta-di
In order to accurately assess the quality of low-resolution biogeophysical parameter products, accurate scale transformations are essential. However, different scaling models often lead to inconsistent transformation results. More worryingly, many biogeophysical parameters are not scale-invariant, such as the Normalized Difference Vegetation Index (NDVI), which makes the quality assessment of low-
Forest disturbances can cause shifts in boreal vegetation cover from predominantly evergreen to deciduous trees or non-forest dominance. This, in turn, impacts land surface properties and, potentially, regional climate. Accurately considering such shifts in future projections of vegetation dynamics under climate change is crucial but hindered (e.g., uncertainties in future disturbance regimes). In
Given the severe land-use and land-cover change pressure on tropical forests and the high demand for field observations of ecosystem characteristics, it is crucial to collect such data both in pristine tropical forests and in the converted deforested land-cover classes. To gain insight into the ecosystem characteristics of pristine tropical forests (EFs), regrowth forests (RFs), and cashew plantat
Meta-analyses are vital for synthesizing evidence in medical research, but conflicts of interest can introduce research bias, undermining the reliability of the synthesized findings. This paper proposes a new robust Bayesian meta-analysis model. The model inflates uncertainty of low-quality studies and incorporates a bias term for studies subject to conflicts of interest. Using a random-effects mo

European forests are being shaped by active human use and management, and by harvesting of wood in particular. Yet, our understanding of how forests are harvested across Europe is limited, as the real harvest regimes are not well described by currently available data. Here, we analyse recent harvests, as observed in permanent plots of forest inventories in 11 European countries, totaling to 182,64
Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground-based long-term forest monitoring with large-scale remote sensing. We surveyed the metadata from 466 865 forest monitoring plots
