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
Agricultural intensification is widely recognised as a primary driver of pollinator loss, but the success of land-management actions designed to remediate its impact is often mixed. Payments to farmers to increase habitat connectivity or the availability of floral and nesting resources may only result in short-term gains or even unintended consequences. The reasons may lie in changes to interactio
Several suggestions have been made as to why Sweden's approach to managing the COVID-19 pandemic came to rely on a strategy based on voluntary measures. Two of the most prominent explanations for why the country chose a different strategy than many other countries have focused on micro- and macro-level factors, explaining the strategy either in terms of the psychologies of prominent actors or by p
Urbanization is a major contributor to biodiversity declines. However, studies assessing effects of urban landscapes per se (i.e., disentangled from focal habitat effects) on biodiversity across spatial scales are lacking. Understanding such scale-dependent effects is fundamental to preserve habitats along an urbanization gradient in a way that maximizes overall biodiversity. We investigated the i
Land sharing versus land sparing describes contrasting strategies to conserve biodiversity while maintaining agricultural production. We comprehensively reviewed empirical studies comparing land-sharing and land-sparing strategies to assess how these were conceptualized and how consequences for biodiver- sity, commodity production, and additional ecosystem services have been quantified. Out of 52
Green infrastructure (GI) is increasingly used in policymaking to promote biodiversity and enhance ecosystem services through the protection, creation, restoration and connection of natural and man-made green areas. The EU Commission adopted in 2013, the concept as a strategy. When member states apply the policy, it is translated into specific bureaucratic and political systems, creating different
Environmental change is disrupting mutualisms between organisms worldwide. Reported declines in insect populations and changes in pollinator community compositions in response to land use and other environmental drivers have put the spotlight on the need to conserve pollinators. While this is often motivated by their role in supporting crop yields, the role of pollinators for reproduction and resu
Neonicotinoids, systemic insecticides that are distributed into all plant tissues and protect against pests, have become a common part of crop production, but can unintentionally also affect non-target organisms, including pollinators. Such effects can be direct effects from insecticide exposure, but neonicotinoids can affect plant physiology, and effects could therefore also be indirectly mediate
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
Duplicative horizontal gene transfer may bring two previously separated homologous genes together, which may raise questions about the interplay between the gene products. One such gene pair is the “native” PgiC1 and “foreign” PgiC2 in the perennial grass Festuca ovina. Both PgiC1 and PgiC2 encode cytosolic phosphoglucose isomerase, a dimeric enzyme whose proper binding is functionally essential.
The interest in putting a price on carbon emissions is increasing in pace with the urgency of climate change. In this article we compare the adoption of one such policy instrument, carbon taxation, in the cases of Sweden and Mexico. We use a theoretical framework that focuses on economic and environmental factors influencing the policy process via distinct policy areas, as well as the mechanisms t
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
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
Pollinators are estimated to benefit the reproduction of three-quarters of global leading crop species and contribute to 3%–8% of the total global food production. Ongoing declines in pollinator populations have raised concerns about repercussions for food security. Thus, there is a need to better understand how agricultural yields depend on pollinator abundance. Here, we established yield–pollina
In the pursuit of more sustainable agriculture, weeds play a dual role by threatening crop production and simultaneously contributing to farmland biodiversity. Management actions such as the use of fertilisers (fertilisation) may change weed abundance and community composition with consequences for both weed–crop competition and biodiversity. Alleviating the balance between yield and biodiversity
DevOps has significantly improved the software development life-cycle by enabling fast, automated, and continuous integration and deployment (CI/CD). However, its application to Cyber-Physical Systems (CPS) presents unique challenges that require rethinking of traditional practices. DevOps in CPS becomes even more challenging when we consider sustainability, which is becoming increasingly importan
Organismal abundance tends to decline with increasing body size. Metabolic theory links this size structure with energy use and productivity, postulating a size–abundance slope of −0.75 that is invariant across environments. We tested the robustness of this relationship across gradients of protist species richness (1–6 species), temperature (15°C–25°C) and time. Using replicated microcosms, we pro
