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
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,
In recent years, low-cost flights to smaller cities in Central and Eastern Europe grew fast. This growth offered tourists new possibilities to explore new, lesser-known destinations at a low price. At the same time, urban tourism is a common strategy for urban regeneration and development in Central and Eastern Europe, and therefore, a significant factor of the economic restructuring of Post-Socia
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
While organisms have evolved to cope with predictable changes in the environment, the rapid rate of current global change presents numerous novel and unpredictable stressors to which organisms have had less time to adapt. To persist in the urban environment, organisms must modify their physiology, morphology and behaviour accordingly. Metabolomics offers great potential for characterising organism
Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household custo-mers and utilities are sometimes only repre-sented through the energy bill. In this thesis, three particular field
Resolving fungal and bacterial groups within the microbial decomposer community is thought to capture disparate life strategies for soil microbial decomposers, associating bacteria with an r-selected strategy for carbon (C) and nutrient use, and fungi with a K-selected strategy. Additionally, food-web model-based work has established a widely held belief that the bacterial decomposer pathway in so
Plant species beta diversity is influenced by spatial heterogeneity in the environment. This heterogeneity can potentially be characterised with the help of remote sensing. We used WorldView-2 satellite data acquired over semi-natural grasslands on The Baltic island of Öland (Sweden) to examine whether dissimilarities in remote sensing response were related to fine-scale, between-plot dissimilarit
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
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
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
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
Increasing human impact on the environment is causing drastic changes in disturbance regimes and how they prevail over time. Of increasing relevance is to further our understanding on biological responses to pulse disturbances (short duration) and how they interact with other ongoing press disturbances (constantly present). Because the temporal and spatial contexts of single experiments often limi
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
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
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
Inom kärnkraftsindustrin är säkerhet den aspekt som prioriteras högst. Alla kärnkraftverk är designade för att i högsta möjliga mån förhindra läckage av radioaktivetet till omgivningen, både under drift och i händelse av en allvarlig olycka. Med anledning av detta är reaktorinneslutningens vägg en av de viktigaste säkerhetsrelaterade konstruktionerna vid en anläggning, detta då denna konstruktionSafety is the top priority at a nuclear facility. The nuclear power plants are designed to prevent radioactive leakage to the surroundings, both during normal operation as well as in case of a severe accident. One of the most important structures in a nuclear power plant, with regard to safety, is thus the reactor containment wall. The containment wall is the last main barrier to prevent radioacti
Although bottom water hypoxia (O2 −1) is presently widespread in the Baltic Sea coastal zone, there is a lack of insight into past changes in bottom water oxygen in these areas on timescales of millennia, and the possible driving factors. Here, we present a sediment-based environmental reconstruction of surface water productivity, salinity and bottom water oxygen for the past 5400 years at Gåsfjär
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, the
