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
We compare Holocene tree cover changes in Europe derived from a transient Earth system model simulation (Max Planck Institute Earth System Model - MPI-ESM1.2, including the land surface and dynamic vegetation model JSBACH) with high-spatial-resolution time slice simulations performed in the dynamic vegetation model LPJ-GUESS (Lund-Potsdam-Jena General Ecosystem Simulator) and pollen-based quantita
Process-based forest models combine biological, physical, and chemical process understanding to simulate forest dynamics as an emergent property of the system. As such, they are valuable tools to investigate the effects of climate change on forest ecosystems. Specifically, they allow testing of hypotheses regarding long-term ecosystem dynamics and provide means to assess the impacts of climate sce
The fate of soil organic matter (OM) is determined by its microbial use for growth or respiration. Many environmental factors influence microbial OM use, including the presence of contaminants and toxins in the environment, such as heavy metals. We evaluated short- and long-term responses of microbial processes to metal contamination by estimating biomass concentrations and growth rates of bacteri
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
QuestionHow do pollen-based functional and phylogenetic diversity help to explain post-glacial vegetation change in relation to climate and human influence? LocationEstonia and Latvia, NE Europe. MethodsWe used a data set of 1062 pollen samples from 20 sites covering the last 14500yrs to estimate plant richness, evenness, functional and phylogenetic diversity (community-weighted mean and mean pair
The relative complexity of the mechanisms underlying savanna ecosystem dynamics, in comparison to other biomes such as temperate and tropical forests, challenges the representation of such dynamics in ecosystem and Earth system models. A realistic representation of processes governing carbon allocation and phenology for the two defining elements of savanna vegetation (namely trees and grasses) may
The major objectives of this paper are: (1) to review the pros and cons of the scenarios of past anthropogenic land cover change (ALCC) developed during the last ten years, (2) to discuss issues related to pollen-based reconstruction of the past land-cover and introduce a new method, REVEALS (Regional Estimates of VEgetation Abundance from Large Sites), to infer long-term records of past land-cove
Popular Abstract in Swedish Professionella balettdansare börjar vanligtvis dansa balett redan vid 8–10 års ålder; pojkar ett par år senare än flickor. Det finns flera utbildningsvägar både i Sverige och utomlands. De flesta börjar sin yrkeskarriär vid 18–20 års ålder. I Sverige är pensionsåldern för institutionsdansare 41–44 år, då man efter 20 års anställning vid svenska institutioner kan få maxiBallet dancers have been shown to have frequent problems with the musculoskeletal system, but little is generally known about the prevalences of musculoskeletal disorders and about working conditions of professional ballet dancers in Sweden. The aims of the thesis were: to analyse the prevalence, location and recurrence of self-reported musculoskeletal disorders (pain) in professional ballet danc
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
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

In this paper we present new relative sea-level data from southern Greenland, a key area for understanding the Greenland Ice Sheet (GIS) response to climate change. Within fourteen lakes and marine lagoons from the inner part of Bredefjord (Nordre Sermilik) in southern Greenland, isolations revealed by stratigraphic and palaeoecological analyses are dated and relative sea levels reconstructed. Due
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
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
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
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
