The tremendous increases in production of plastic materials has led to an accumulation of plastic pollution worldwide. Many studies have addressed the physical effects of large-sized plastics on organisms, whereas few have focused on plastic nanoparticles, despite their distinct chemical, physical and mechanical properties. Hence our understanding of their effects on ecosystem function, behaviour
Ecological intensification of agriculture implies managing ecological processes to improve performance of agricultural systems. However, impacts on relevant ecological functions such as insect pollination from other crop management factors are poorly explored. Pest insects and crop resources such as water availability can directly affect crop yields, but it is unknown if there are indirect effects
We propose a model to consider data dependencies and assess spatial and temporal variability in land use specific floral coverage across landscapes. Data dependence arising from repeated measurements across the flowering season is taken into account using hierarchical Archimedean copulas, where the correlation is assumed to be stronger within seasonal periods than between periods. For each seasona
Strawberry and oilseed rape are economically important and co-flowering insect-pollinated crops that may affect each other via shared pollinators. One potential negative effect of pollinator sharing is stigma clogging, i.e. that pollen from one plant species covers the stigma and prevents pollination in the other. We tested if application of oilseed rape pollen on strawberry receptacles reduces po
Aims: Climate change is known to drive both the reshuffling of whole assemblages and range shifts of individual species. Less is known about how local colonizations and extinctions of individual species contribute to changes at the community level. Our aim was to estimate the contribution of individual species to a change in community composition attributed to climate change and to relate these sp
En stor del av världens sjötransporter går mellan Asien och Europa. Idag är den södra rutten genom Suez-kanalen populärast, men efter att isen i Arktis börjat smälta har den norra rutten öppnats upp som en möjlig utmanare till den södra rutten och skeppsägare ställs nu inför ett val. Sjötransport är en riskfylld verksamhet och både den södra och den norra rutten innehåller områden med ökad risk. There are two main shipping routes between Europe and Asia, among those the Southern Route through the Suez Canal is by far the most popular route. Due to a decrease in Arctic sea ice, the Northern Sea Route have opened up and is expected to become a viable alternative and a possible competitor to the Southern Route. The purpose of this essay is to contribute by advising ship-owners on what route
Den moderna ekonomin präglas av globalisering, kunddriven marknad och ett mer tjänstedrivet affärslandskap. Det innebär att det idag sluts fler och mer komplexa långtidskontrakt vilka ofta kompletteras av tilläggsavtal. Tendenserna i den moderna ekonomin rörande avtalsstrukturer är intressant i förhållande till tvistlösning i skiljedomstol. Lag (1999:116) om skiljeförfarande stadgar att för att
It has been suggested that the widespread use of neonicotinoid insecticides threatens bees, but research on this topic has been surrounded by controversy. In order to synthesize which research approaches have been used to examine the effect of neonicotinoids on bees and to identify knowledge gaps, we systematically reviewed research on this subject that was available on the Web of Science and PubM
Agriculture's reliance on ecosystem services creates economic and ecological interdependencies between crop production and biodiversity. Interactions with mobile organisms are particularly complex because they depend on the spatial configuration of habitat at large scales. As such conserving habitat is likely to benefit multiple farmers whereas conservation costs are born individually, creating po
Research relating to ecosystem services has increased, partly because of drastic declines in biodiversity in agricultural landscapes. However, the mechanistic linkages between land use, biodiversity and service provision are poorly understood and synthesized. This is particularly true for many ecosystem services provided by mobile organisms such as natural enemies to crop pests. These species are
Background/introduction: E-commerce is becoming a natural part of retail business. In order to achieve a competitive edge, companies are shifting to omni channel retailing where channel integration is explored in the search for potential improvements in connection with customer offer and costs. One solution is to integrate inventories and offer improved order fulfilment by using both warehouse and
Methodology: Using an abductive approach, a qualitative case study of the sharing economy Desk Doubler has been implemented. Empirical data was collected through semi-structured interviews with employees at Desk Doubler and their customers with the purpose to create an understanding of how the perceived search, negotiation and monitoring costs have been affected by the use of Desk Doubler. Accordi
Technical advancements and changes to the environment imply that industries may experience technology shifts. During those times, mature manufacturing companies are vulnerable, and it is of outmost importance they can respond to the new circumstances. To do so, mature manufacturing companies need to know which consequences they will experience to their offer, business model, resources and capabili
Marknadsförarens roll består i hög utsträckning av att stimulera och expandera efterfrågan på produkter och tjänster. I takt med att konsumtionen i samhället växer och resurserna samtidigt minskar står dock marknadsförarens roll inför en oundviklig förändring om de globala miljömålen ska uppnås. För att anpassa sig och i slutändan kunna dra fördel av denna transformation krävs vidare kunskap kringA significant part of the marketing profession consists of stimulating and expanding the demand for products and services. However, as society’s level of consumption increases at the same time as our resources decrease, the marketer’s role faces an inevitable change if the global environmental goals are to be achieved. In order to adapt and ultimately benefit from this transformation, marketers ne
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
