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
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
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ-diversity), either due to reduced β-diversity amplifying diversity loss or increased β-diversity dampening diversity loss. Additionall
Anthropogenic land-use and climate change pose novel selection pressures on bees, yet their evolutionary responses in terms of morphological or physiological adaptations remain unclear. While adaptive responses are expected, these may be constrained by gene flow when changes in selection pressures are spatially heterogeneous. The buff-tailed bumblebee (Bombus terrestris) is a widespread species th
Residential gardens can provide pollinator habitat and thus contribute to mitigating declines of insect pollinators. To further improve gardens for pollinators, it is necessary to understand the factors and pathways leading to successful conservation interventions. We studied how the success of two common pro-pollinator interventions, garden meadows and flower plantings, were influenced by gardene
Bioenergy derived from agricultural biomass can contribute to meeting the rising demand for renewable energy. To estimate the agricultural sector's potential to contribute to bioenergy, it is crucial to understand what motivates farmers to increase agricultural feedstock production sustainably. Through eight semi-structured interviews and online surveys with 174 farmers in southern Sweden, we expl
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

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
Construction using timber has seen a resurgence in light of global climate mitigation policies. Wood is a renewable resource, and engineered wood products are proving to be competitive against concrete and steel while having several advantages. However, while the renewable nature of wood in construction is a beneficial property for climate mitigation policies, the process of biodegradation introdu
Background: Acute myeloid leukemia (AML) patients have limited effect from T-cell-based therapies, such as PD-1 and CTLA-4 blockade. However, recent data indicate that AML patients with TP53 mutation have higher immune infiltration and other immunomodulatory therapies could thus potentially be effective. Here, we performed the transcriptional analysis of distinct T-cell subpopulations from TP53-mu
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
Just nu finns det en möjlighet för politikerna att lägga om stadsplaneringen så att det blir möjligt att nå FN:s hållbarhetsmål. Det skriver åtta forskare som arbetar med miljö- och hälsofrågor.
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
The concept of authentic leadership is increasingly the focus of much leadership scholarship, and many have called for a review of the basic assumptions that underpin it. Taking an interactional approach to authentic leadership (AL) and using naturally occurring workplace interaction as data, we seek to question two basic assumptions of AL scholarship, namely (1) that authentic leadership emanates
Fatty acid biomarkers have emerged as a useful tool to quantify biomass of various microbial groups. Here we focus on the frequent use of the fatty acid 16:1ω5 as a biomarker for arbuscular mycorrhizal (AM) fungi in soils. We highlight some issues with current applications of this method and use several examples from the literature to show that the phospholipid fatty acid (PLFA) 16:1ω5 can occur i
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
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
