Infectious and parasitic agents (IPAs) and their associated diseases are major environmental stressors that jeopardize bee health, both alone and in interaction with other stressors. Their impact on pollinator communities can be assessed by studying multiple sentinel bee species. Here, we analysed the field exposure of three sentinel managed bee species (Apis mellifera, Bombus terrestris and Osmia
Intensity Analysis (IA) of land use and land cover change (LULCC) is important to support policy and practice. We applied IA to analyse LULCC in Sironko catchment, Uganda. Results show that agricultural land, forest, and wetland reduced by 8%; 32%; and 20% between 1986-2000. Between 2000-2016, forest, wetland, and built-up areas increased by 84%, 5%, and 57%. Active gainers between 1986-2000 were
Bioenergy is perceived to play a vital role in climate mitigation, transition to renewable energy consumption, energy security, and local and rural socio-economic development. However, exploiting renewable bioenergy resources may need to be more sustainable in the current predominant paradigm. In this study, we raise two broad research questions: (1) what are the significant challenges to the curr

With computers embedded almost everywhere, in domestic, industrial, and medical appliances and devices, computing is becoming increasingly pervasive. Services in pervasive systems can be combined and coordinated through user-defined scripts called assemblies, a light-weight and understandable way for end users to adapt services to fit their specific needs. Previous languages for assembly scripts
European semi-natural grasslands are hotspots for biodiversity and important for the provisioning of multiple ecosystem services, but their extent has declined considerably during the past century. Increasing demands for agricultural and forest biomass risk causing further loss of grasslands, raising concern about a goal conflict between climate mitigation and biodiversity conservation. This study
Local climate adaptation is constrained and steered along specific paths by various mechanisms, which together form a lock-in. The study focuses on Swedish local civil servants’ strategies to deal with climate adaption lock-ins and to what extent the strategies disrupt the lock-ins. Interviews were conducted with civil servants in six municipalities, complemented by inter-views at regional and nat
Bee-mediated pollination plays a crucial role in sustaining global food production. However, while the demand for these pollination services is increasing, many bee species are in decline. To address this discrepancy, farmers use managed bee species to improve crop pollination. One key factor affecting pollination efficiency is the affinity for the crop of interest (i.e., the extent to which a bee
To reverse biodiversity loss, creating resilient ecological networks has been promoted in policy and practice. However, we argue that emphasising networks within policy without clear conservation prioritisations may direct focus away from ecological processes important for population persistence. We studied the rationale for resilient ecological networks represented in a policy context, by reviewi
This thesis combines Judith Butler’s concept of gender understood as a performance and Guy Debord’s Society of the Spectacle in order to apply it onto the sexually charged imagery in anime known as “fan service.” In doing so, it endeavours to answer what visually constitutes a gendered performance in fan service, and how those visuals can be read as a form of spectacle. It finds that fan service c
This thesis aims to study the decision making process behind the solidarity mechanism in the EU legislative package a New Pact on Migration and Asylum. The legislation covers the issue of relocation of asylum seekers and other efforts towards a joint responsibility for the migration management. Since the migration crisis in 2015 the migration issue has been high on the agenda. Simultaneously, any
Resource competition between wild pollinators and managed honeybees (Apis mellifera) has the potential to detrimentally impact insect biodiversity as well as wild plant and crop pollination. As honeybees are central place foragers, their competitive impact on wild bees is expected to be structured by hive proximity, in conjunction with foraging decisions related to landscape-level resource availab
In times of major global interconnectedness and environmental change, the pressure to identify, create, and exploit new resources is certain to intensify. Given that there are unavoidable trade-offs, conflicts, and arenas for violence involved when increasingly more material and immaterial things are turned into resources, we call for explicit research on the very process – a process that we label
Riverine colloids are important carriers of macronutrients, trace metals, and pollutants into marine waters. The aim of the current study was to extend the understanding of iron (Fe) and organic carbon (OC) colloids in boreal rivers and their fate at higher salinities. X-ray absorbance spectroscopy (XAS) and dynamic light scattering (DLS) were combined to explore Fe speciation and colloidal charac

How do fungi navigate through the complex microscopic maze-like structures found in the soil? Fungal behaviour, especially at the hyphal scale, is largely unknown and challenging to study in natural habitats such as the opaque soil matrix. We monitored hyphal growth behaviour and strategies of seven Basidiomycete litter decomposing species in a micro-fabricated "Soil Chip" system that simulates pr
Site-specific land management practice taking into account variability in maize yield gaps (the difference between yields in the 90th percentiles and other yields on smallholder farmers’ fields) could improve resource use efficiency and enhance yields. However, the applicability of the practice is constrained by inability to identify patterns of resource utilization to target application of resour
Uncertainty refers to any limitation in knowledge. Identifying and characterizing uncertainty in conclusions is important to ensure transparency and avoid over or under confidence in scientific assessments. Quantitative expressions of uncertainty are less ambiguous compared to uncertainty expressed qualitatively, or not at all. Subjective probability is an example of a quantitative expression of e
The ongoing wide-scale introduction of nonnative plants across the world may negatively influence native invertebrate fauna, due to a lack of coevolved traits related to the novel plants, e.g., unique phytochemicals or shifted phenology. Nonnative plants, specifically trees, are common in urban environments, areas that already pose novel habitats to plants and wildlife through a wide array of anth
