Neonicotinoid insecticides applied to flowering crops can have negative impacts on bees, with implications for crop pollination. To assess if exposure to the neonicotinoid clothianidin via a treated crop (rapeseed) affected bee behaviour, pollination performance (to strawberry), and bee reproduction, we provided each of 12 outdoor cages with rapeseed (autumn-sown plants complemented with a few spr
Magneto-optical (MO) effects, viz. magnetically induced changes in light intensity or polarization upon reflection from or transmission through a magnetic sample, were discovered over a century and a half ago. Initially they played a crucially relevant role in unveiling the fundamentals of electromagnetism and quantum mechanics. A more broad-based relevance and wide-spread use of MO methods, howev
Recent technological advancements now allow us to obtain geographical position data for a wide range of animal movements. Here we used light-level geolocators to study the annual migration cycle in great reed warblers (Acrocephalus arundinaceus), a passerine bird breeding in Eurasia and wintering in sub-Saharan Africa. We were specifically interested in seasonal strategies in routes and schedules
Rewetting a dry soil can result in two response patterns of bacterial growth and respiration. In type 1, bacterial growth starts to increase linearly immediately upon rewetting and respiration rates are highest immediately upon rewetting. In type 2, bacterial growth starts to increase exponentially after a lag period with a secondary increase in respiration occurring at the start of the exponentia
Studies using satellite sensor-derived data as input to models for CO2 exchange show promising results for closed forest stands. There is a need for extending this approach to other land cover types, in order to carry out large-scale monitoring of CO2 exchange. In this study, three years of eddy covariance data from two peatlands in Sweden were averaged for 16-day composite periods and related to
Popular Abstract in Swedish Inom forskningsområdet biogeokemi studerar man hur naturens olika grundämnen, såsom kol, kväve, fosfor och kisel ändrar form och transporteras genom landskapet för att via bäckar och vattendrag till slut nå havet. Tillsammans beskriver dessa olika processer, som sker på olika tidsskalor, från sekunder till flera miljoner år, ett grundämnes kretslopp (eller biogeokemiskaSilicon is the next most abundant element in the Earth’s crust and its biogeochemical cycle is linked with that of carbon. Further, silicon is a beneficial nutrient for plants in terrestrial ecosystems and a key nutrient for diatoms in aquatic ecosystems. During the last decade the important role of terrestrial vegetation in controlling Si fluxes downstream aquatic environments, via incorporation
Weathering of silicate minerals releases dissolved silicate (DSi) to the soil-vegetation system. Accumulation and recycling of this DSi by terrestrial ecosystems creates a pool of reactive Si on the continents that buffers DSi export to the ocean. Human perturbations to the functioning of the buffer have been a recent research focus, yet a common assumption is that the continental Si cycle is at s
Questions Can the model performance of the landscape reconstruction algorithm (LRA) for small forest hollows be validated through comparison to inventory-based vegetation reconstructions from the last 150yrs? Does the application of LRA and the comparison to historical data enhance interpretation of the pollen record? Location Denmark. The Gribskov-Ostrup small forest hollow (56 degrees N, 12 degr
BACKGROUND: The increasing need for long-term care as well as diminished financial resources may compromise the quality of care of older people. Thus the need for clinically based quality of care monitoring to guide development of long-term services has been pointed out. OBJECTIVES: The aim of this study was to investigate trends in quality of care during 2003-2009 as reflected in the Minimum
Mitt syfte med uppsatsen är att undersöka hur väl forensikers egen uppfattning om vad de bör uttala sig om och vad de inte bör uttala sig om stämmer överens med en idealbild av expertrollen. Mot bakgrund av syftet ställdes elva påståenden till 50 forensiska experter vid Nationellt forensiskt centrum (NFC) i form av en enkätundersökning. De sätt på vilka forensiker kan avvika från idealet som testaMy purpose with this thesis is to examine how well forensic experts` understanding of what they should and should not express opinions on is in accordance with an idealized view of the expert role. Given my purpose with the thesis, eleven statements were presented in a survey to 50 forensic experts working at the Swedish National Forensic Centre (NFC). Two deviations from the ideal view of an expe
Deforestation, mainly driven by agricultural expansion, is a global problem, interlinked with many pressing sustainability issues of our time, first and foremost, climate change. Previous private corporate initiatives and public policies such as FLEGT and the EUTR have not succeeded in overturning the trend. As a response to that, EU deforestation regulation was developed as the new demand-side po
Although a large volume of work has been conducted regarding tourism industries across the world, the dominant analysis in the geographies of tourism tends to draw upon post-modern discourse analysis and representational theories. This has resulted in calls to develop more materialist analyses of tourism landscapes. Using the case study of Long Bay, a small coastal settlement in Portland parish, J
Examensarbetet går ut på att analysera elsparkscykelns funktion utifrån de tre delarna som ingår i begreppet hållbarhet, ekonomisk, ekologisk och social. Då trafikslaget är relativt nytt i Sverige, är det många brister i reglering och kunskap kring elsparcykeln i landet. Syftet med examensarbetet är att fördjupa sig i de tre delarna som ingår i hållbarhetsbegreppet, för att i sin tur kunna analyseThe purpose with the thesis project is to analyse the function of E-scooters from the three parts that comes with sustainability, which is economic, environment and social sustainability. Because it is a new vehicle, it comes with a large amount of deficits when it comes to regulation and knowledge. To get a deeper awareness about the consequences is the reason why sustainability is applied in thi
With the emergence of industrialisation, the work-life balance has become a point of discussion in many industries, among which the aviation industry. Distortions in the work-life balance became especially apparent when 24/7 economies evolved, and industries made a transition to facilitate and serve these economies. Incidents and accident have since then been related to fatigue more than before. T
This article analyses why Singapore compared to Iceland, has received greater amount of FDIs during the time from year: 1977-2007. FDIs have often been proven to increase a state’s economy since it is used as a tool for states to establish a long term relationship and trade with each other. Moreover, New Economic Geography (NEG), a theory written by Paul Krugman will be used to prove that the geog
This study uses a 12-year time series (2001-2012) of eddy covariance measurements to investigate the long-term net ecosystem exchange (NEE) of carbon dioxide (CO2) and inter-annual variations in relation to abiotic drivers in a boreal fen in northern Sweden. The peatland was a sink for atmospheric CO2 in each of the twelve study years with a 12-year average (+/- standard deviation) NEE of -58 +/-
We used an extensive dataset (1220 vegetation plots of 1 m(2)) to study vegetation gradients and fine-scale plant diversity in dry calcareous grasslands (including alvar grasslands) in the Baltic Sea region. The study area covers the entire European distributional range of alvar habitats: Sweden (Oland, Gotland, Gotaland), Estonia (Saaremaa, Hiiumaa, north Estonia, west Estonia), and western Russi
When the Act on System of choice was implemented on the Swedish homecare market in 2009, there seemed to be an assumed understanding that by increasing competition on the eldercare market through privatization it would create better opportunities for women. Entrepreneurship was phrased as a solution for empowering and emancipating women in breaking out from a fixed role in low-status professions.
Improved management of agricultural soils to sequester carbon from the atmosphere is considered an important climate mitigation measure. Intensive agriculture often leads to degradation of soil organic carbon (SOC), contributing to climate change and loss of soil ecosystem services. Interventions in agricultural management can halt or reverse the loss of SOC. Annual SOC change rates for interventi
This degree project focuses primarily on the requirements related to energy and the environment that are associated with buildings. As a small contribution towards a more sustainable society, piping insulation used for insulating heating or cooling systems has been studied. During the lifetime of a building, these systems can result in large energy losses that cause significant environmental impac
