Continuous water-table (WT) measurements from peatlands are scarce and – if existing at all –very short. Consequently, proxy indicators are critically needed to simulate hydrological changes in peatlands over longer time periods. In this study, we demonstrate that tree-ring width (TRW) records of Scots pine (Pinus sylvestris L.) growing in the Čepkeliai peatland (southern Lithuania) can be used as

Accurately quantifying soil base cation pool sizes is essential to interpreting the sustainability of forest harvests from element mass-balance studies. The soil-exchangeable pool is classically viewed as the bank of "available" base cations in the soil, withdrawn upon by plant uptake and leaching and refilled by litter decomposition, atmospheric deposition and mineral weathering. The operational

The closed chamber technique is widely used to measure the exchange of methane (CH4) and carbon dioxide (CO2) from terrestrial ecosystems. There is, however, large uncertainty about which model should be used to calculate the gas flux from the measured gas concentrations. Due to experimental uncertainties the simple linear regression model (first-order polynomial) is often applied, even though the

Background: Little is known about the long-term effectiveness of behavioural therapy for tics. We aimed to assess the long-term clinical and cost-effectiveness of online therapist-supported exposure and response prevention (ERP) therapy for tics 12 and 18 months after treatment initiation. Methods: ORBIT (online remote behavioural intervention for tics) was a two-arm (1:1 ratio), superiority, sing

Estimates of land-atmosphere exchanges of carbon, energy, water vapor, and other greenhouse gases based on the eddy covariance (EC) technique rely on the fundamental assumption that the flux footprint area is homogeneous. We investigated the impact of source area heterogeneity on flux estimates in single-level EC measurements over a managed boreal forest landscape. For this purpose, we compared si

The importance of semi-arid ecosystems in the global carbon cycle as sinks for CO 2 emissions has recently been highlighted. Africa is a carbon sink and nearly half its area comprises arid and semi-arid ecosystems. However, there are uncertainties regarding CO 2 fluxes for semi-arid ecosystems in Africa, particularly savannas and dry tropical woodlands. In order to improve on existing remote-se

A particular focus in this paper is the delicate issue of possible over-production of European films, a situation which has either been spelled out or implied in a number of reports, chapters, books and doctoral dissertations on European cinema during the last decade. In a 2014 eight page briefing (referenced below), for instance, it was suggested that between 2001 and 2008 total investment in EU

Sediment records recovered from the Baltic Sea during Integrated Ocean Drilling Program Expedition 347 provide a unique opportunity to study paleoenvironmental and climate change in central and northern Europe. Such studies contribute to a better understanding of how environmental parameters change in continental shelf seas and enclosed basins. Here we present a multi-proxy-based reconstruction of

Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, and carbon budgets at the land-atmosphere interface. However, despite being the main land evaporative flux at the global scale, transpiration and its response to environmental drivers are currently not well constrained by observations. Here we introduce the first global compilation

The forest floor provides an important interface of soil-atmosphere CO2 exchanges but their controls and contributions to the ecosystem-scale carbon budget are uncertain due to measurement limitations. In this study, we deployed eddy covariance systems below- and above-canopy to measure the spatially integrated net forest floor CO2 exchange (NFFE) and the entire net ecosystem CO2 exchange (NEE) at

Background Late blight (caused by Phytophthora infestans) is a devastating potato disease that has been found to occur earlier in the season over the last decades in Fennoscandia. Up until now the reasons for this change have not been investigated. Possible explanations for this change are climate alterations, changes in potato production or changes in pathogen biology, such as increased fitness o

Handel med så kallade osanna fakturor är ett relativt avancerat upplägg som används i syfte att undvika beskattning. Med begreppet osann faktura avses en faktura som ger sken av att ett avtal ingåtts mellan två parter, vanligtvis om köp av tjänster eller varor, men där avtalet mellan parterna i själva verket avser köp av själva fakturan. Motivet bakom upplägg med osanna fakturor är i regel att minThe trading with so-called untrue invoices is a relatively advanced scheme used in order to avoid taxation. The term untrue invoice refers to an invoice that indicates that an agreement regarding purchase of services or goods has been made between two un-associated parties, when the agreement between the parties in fact relates to the purchase of the invoice itself. The motive behind the usage of

With millions of yearly beach visitors in southern California, beach water quality represents an important factor in public health and ocean dependent economy. Fecal indicator bacteria (FIB) in water is much easier to measure than disease causing organisms but correlation exists between the two. For this reason, FIB concentrations are used to measure recreational water quality and related health r

Från år 2021 ska alla nybyggnationer i Europa vara nära-nollenergibyggnader. Detta innebär att byggnaders energianvändning bör vara låg och i mycket hög grad tillförs i form från förnybara energikällor som produceras på plats eller i närheten. Syftet med de höga energikraven är att påskynda takten för att skapa ett mer energieffektivt byggande. Den minskade energianvändningen tillsam-mans med en öFrom year 2021, all new buildings in Europe will be net zero-energy buildings. This means that the building's energy is supplied from renewable energy sources that are produced on site or nearby. The purpose of the high energy requirements is to accelerate the pace of creating more energy-efficient constructions. The reduced energy consumption, together with increased use of renewable energy,

Pollination by bees is important for food production. Recent concerns about the declines of both domestic and wild bees, calls for measures to promote wild pollinator populations in farmland. However, to be able to efficiently promote and prioritize between measures that benefit pollinators, such as modified land use, agri-environment schemes, or specific conservation measures, it is important to

Popular Abstract in Swedish Det traditionella jordbruket i nordvästra Europa har gynnat förekomsten av många arter under tusentals år och den snabba övergången till modernt jord- och skogsbruk har lett till försämrade förutsättningar för dessa arter. Både internationellt och nationellt finns strategier för att bevara biologisk mångfald. I Sverige är dessa strategier integrerade i miljömål med ansThis thesis explores the relationship between land-use and floristic diversity over the last three millennia in the uplands of southern Sweden. A quantitative approach based on high-resolution pollen data was applied, using the Landscape Reconstruction Algorithm (LRA), historical maps/aerial photographs, palynological richness and new ways to estimate past evenness at regional and local spatial sc

I 10 § 2 st. AvtL regleras en vanlig och i praktiken viktig fullmaktsform, nämligen ställningsfullmakten. Paragrafen ska läsas tillsammans med 10 § 1 st., 11 § 1 st., och 15 § AvtL men de rekvisit som är karakteristiska för just ställningsfullmakten är att mellanmannen i följd av ett avtal med huvudmannen, ska inneha en ställning som ger mellanmannen viss behörighet att rättshandla för huvudmannenThe “position of authority” (ställningsfullmakt) is amongst the most common and perhaps one of the most important types of power of attorney. The regulation is found in section 10 paragraph 2 of the Swedish Contracts Act 1915 (SCA) and states: “A person who, being employed in the service of another party or otherwise as a result of an agreement with another party, occupies a position which, accord

The doctrine of supremacy in Community law was established by the jurisprudence of the European Court of Justice and has evolved over time since the early case law of Van Gend en Loos and Costa-ENEL. The principle is an unwritten rule and a basic characteristic of Community law and has never been enshrined as a part of the European Treaties. It is evident that there will be clashes between the law

As climate change and unsustainable waste practices present major global challenges, effective waste management in developing countries becomes critically important. In South Africa, organic waste constitutes a significant share of general waste and is often landfilled, contributing to methane emissions and serious health risks for the population. In response, the Western Cape province has introdu
