Mathematical models are useful for predicting the reactions of watercourses such as rivers due to the entry of contaminants. Some of these models are able to simulate the effects of present and future loadings as well as aid managers and officials in making decisions even if the data are sparse. In other words, river water quality preservation requires more investment in wastewater treatment and/o
Background and aims – Agricultural intensification and loss of farmland heterogeneity have contributed to population declines of wild bees and other pollinators, which may have caused subsequent declines in insect-pollinated wild plants. Material and methods – Using data from 37 studies on 22 pollinator-dependent wild plant species across Europe, we investigated whether flower visitation and seed
Taking as its starting point the scholarly discussion about the possible death of the Aesopic fable towards the end of the eighteenth century, this article proposes a broadening of perspective, arguing for a thorough examination of the impact of modernity on some of the basic contexts and conditions of the genre. Four contextual factors are, subsequently, placed under scrutiny: the ethics of virtu
Globally, biodiversity offsetting is used to balance negative impacts on biodiversity and ecosystem services caused by exploitation. In Sweden, there is an increasing interest in biodiversity offsetting in urban planning. However, there is limited understanding about the use of the concept in a municipal context. This study aims to examine and critically reflect on the uptake and use of biodiversi
Bumblebees are a key taxon contributing to the provision of crop pollination and ecosystem functioning. However, land use and climate change are two of the main factors causing bee decline across the world. In this study, we investigated how the flight period of bumblebee spring queens has shifted over the last century in Sweden, and to what extent such shifts depended on climate change, landscape
Treatment with metformin in type 2 diabetes mellitus-new routines when renal function is reduced and in connection with administration of iodine contrast media Metformin is eliminated through glomerular filtration and tubular secretion in the kidneys. New guidelines recommend use of metformin down to a GFR of 30 mL/min under the condition that the dose is adjusted. As the risk of inducing lactic a
The common conception of justice as reciprocity seemingly is inapplicable to relations between non-overlapping generations. This is a challenge also to John Rawls’s theory of justice as fairness. This text responds to this by way of reinterpreting and developing Rawls’s theory. First, by examining the original position as a model, some revisions of it are shown to be wanting. Second, by drawing on
Many small farmland ponds are built for nutrient retention, the conservation of biodiversity or both, yet they are relatively neglected habitats. For example, little is known about the potential for ponds to influence populations of beneficial terrestrial insects, deliver ecosystem services across the aquatic-terrestrial boundary and affect crop yield in insect-pollinated cash crops.We assessed wh
Agricultural fertilization significantly affects arbuscular mycorrhizal fungal (AMF) community composition. However, the functional implications of community shifts are unknown, limiting understanding of the role of AMF in agriculture. We assessed AMF community composition at four sites managed under the same nitrogen (N) and phosphorus (P) fertilizer regimes for 55 yr. We also established a glass
The thesis examines to what extent dominant undertakings, within the evolving technology industry, are considered to use an anti-competitive conduct when strategically combining technical tying and different patent combinations. Such conduct may result in leveraging a position from one product market to another, leading to evergreening and possible abuse of such dominant position, in accordance to
As a result of insufficient harmonization between domestic tax systems, opportunities have occurred for multinational enterprises (MNE’s) to use aggressive tax planning. To overcome the difficulties, countries must be able to exchange information about the MNE’s tax payments. OECD and the EU have developed country-by-country reporting (CbCR) to ease the exchange of information. CbCR contains an ob
The carbon intensity is an important metric that provides a clear measure of the environmental impact associated with the electricity use. Carbon intensity of electricity use is differentiated into CO₂ equivalents per kilowatt-hour, which standardises the measurement by expressing the emissions of various greenhouse gases in terms of the equivalent amount of CO₂ based on their global warming poten
Effective governance and management of ecosystem functions to promote human well-being and social equity require a clear understanding of supply and demand dynamics. While this is widely acknowledged in assessments of ecosystem services, it remains largely neglected for ecosystem disservices, despite many ecosystem functions generating both services (benefits) and disservices (costs) depending on

Landscape-scale land use is important in driving species communities and interactions. However, despite increasing concerns regarding the ecological consequences of insect declines, our understanding of how the relative proportions of different land cover types influence insect herbivory in species-rich semi-natural habitats remains limited. This study assessed leaf, stem, and flower herbivory acr
The collective impacts of farmers' land management decisions on above ground ecosystem services (ES) and their implications for agriculture are poorly understood. Managing habitat to provide ES is costly but at the same time it can support higher yields through, e.g., pollination or natural pest control. Due to the mobility of ES-providers (bees, natural enemies) farmers providing habitat might al
Are there indications for the neoliberal hegemony in economy and society to come to an end? Are people already imagining a future within environmental limits and beyond the growth imperative? Theoretically, building upon Marx and Bourdieu, we reconstruct the ideological impact that capitalism, in general, and neoliberalism, in particular, has on the ways we think, feel and make sense of our enviro
Climate change and eutrophication are two environmental threats that can alter the structure of freshwater ecosystems and their service functions, but we know little about how ecosystem structure and function will evolve in future scenarios of climate warming. Therefore, we created different experimental climate scenarios, including present-day conditions, a 3.0 °C increase in mean temperature, an
