The daily transition between day and night, known as the diel cycle, is characterised by significant shifts in environmental conditions and biological activity, both of which can affect crucial ecosystem functions like pollination. Despite over six decades of research into whether pollination varies between day and night, consensus remains elusive. We compiled the evidence of diel pollination from
Hydrological modelling is essential for effective water resources management, as it represents complex physical processes through mathematical equations to improve our understanding of the water cycle. FLEXG is a glacio-hydrological model that has been successfully applied and found to perform well in glacierized regions. This study seeks to improve the capability of classical FLEXG model for glac
Aim: Self-reported cognitive function has been described as an important complement to performance-based measurements but has seldom been investigated in cardiac arrest (CA) survivors. Therefore, the aim was to describe self-reported cognitive function and its association with health status, psychological distress, and life satisfaction.Methods: This study utilised data from the Swedish Register oAim: Self-reported cognitive function has been described as an important complement to performance-based measurements but has seldom been investigated in cardiac arrest (CA) survivors.

When Sweden adopted its carbon tax in 1990, it was as one of the first of its kind worldwide. While the adoption of the tax has been attributed to its inclusion in the Swedish tax reform, undoubtedly playing a crucial role, the reform does not in itself explain how the Swedish carbon tax came about or why it became part of the reform package in the first place. In this article, we present a case s
The concentration of colored dissolved organic matter (CDOM) in lakes is strongly influenced by climate, land cover, and topographic settings, but it is not known how drought may affect the relative importance of these controls. Here, we evaluate the controls of CDOM during two summers with strongly contrasting values of the Palmer drought index (PDI), indicating wet vs. dry conditions. We hypothe
Conservation biological control in agricultural landscapes aims to promote natural enemy populations to mitigate short and long-term pest damage on crops. However, natural enemy populations in agricultural landscapes typically rely on crop pests and non-pest prey populations resulting in complex trait- dependent ecological interactions. Such communities, of pests, non-pest prey, and natural enemie
One of the most important challenges for modern society is how to feed the world in a sustainable manner. Agriculture is an essential part of food production, but at the same time it has many negative impacts on the environment, through for example pollution, nutrient leaching, and greenhouse gas emissions, and it is a big driver of biodiversity loss. Organic farming is a farming system that in ma
The Amazon is rapidly approaching an ecological tipping point driven by deforestation, forest degradation and global climate change. These are visible issues that receive increasing political and public attention.However, the accelerating biocultural loss in the Amazon, including the extinction of Indigenous languages, the disruption of Indigenous and local knowledge systems, and the disintegratio
Cutting edge preparation is crucial in metal cutting as the edge geometry significantly influences both the material removal process and tool life. However, an analytical model that can physically describe the cutting edge preparation process has not yet been established. Taking the wet abrasive jet machining (WAJM) method as an example, the following questions always remain: Why does WAJM always
The majority of soil carbon (C) is stored in organic matter associated with reactive minerals. These mineral-organic associations (MOAs) inhibit microbial and enzymatic access to organic matter, suggesting that organic C within MOAs is resistant to decomposition. However, plant roots and rhizosphere microbes are known to transform minerals through dissolution and exchange reactions, implying that
A common migratory pattern in birds is that northerly breeding populations migrate to more southerly non-breeding sites compared to southerly breeding populations (leap-frog migration). Not only do populations experience differences in migration distances, but also different environmental conditions, which may vary spatiotemporally within their annual cycles, creating distinctive selective pressur

Soil functions can be classified as supporting (nutrient cycling) and provisioning (crop production) ecosystem services (ES). These services consist of multiple and dynamic functions and are typically assessed using indicators, e.g. microbial biomass as an indicator of supporting services. Agricultural intensification negatively affects indicators of soil functions and is therefore considered to d
Bumble bee abundance in agricultural landscapes is known to decrease with increasing distance from seminatural grasslands, but whether the pollination of bumble-bee-pollinated wild plants shows a similar pattern is less well known. In addition, the relative effects of landscape composition (landscape heterogeneity) and landscape configuration (distance from seminatural grassland) on wild plant pol
Spatiotemporal resource continuity promotes persistence of mobile animal populations. Current agricultural landscapes are poor in flowers resources for bumble bees. Available forage crops are predominantly early-season mass-flowering crops (MFC). It has been suggested, but not tested, that scarcity of late-season flower resources are limiting bumble bee populations. We examined whether addition of
Effects of landscape heterogeneity and farming practice on species composition are less well known than those on species richness, in spite of the fact that community composition can be at least as important for ecosystem services, such as pollination. Here, we assessed the effect of organic farming and landscape heterogeneity on pollinator communities, focusing on multivariate patterns in species
Soil biodiversity through its delivery of ecosystem functions and attendant supporting ecosystem services-benefits soil organisms generate for farmers-underpins agricultural production. Yet lack of practical methods to value the long-term effects of current farming practices results, inevitably, in short-sighted management decisions. We present a method for valuing changes in supporting soil ecosy
Growing evidence for declines in wild bees calls for the development and implementation of effective mitigation measures. Enhancing floral resources is a widely accepted measure for promoting bees in agricultural landscapes, but effectiveness varies considerably between landscapes and regions. We hypothesize that this variation is mainly driven by a combination of the direct effects of measures on
