Although solitary bees are considered to play key roles in ecosystem functions, surprisingly few studies have explored their population dynamics. We investigated the population dynamics of a rare, declining, solitary bee (Andrena humilis) in a landscape of 80 km 2 in southern Sweden from 2003 to 2011. Only one population was persistent throughout all years studied; most likely this population supp
Dissolved organic carbon (DOC) is one of the most active and mobile carbon pools, and thus an important component of the global carbon cycle. Previous research on DOC transport in the soil and on factors controlling DOC export towards the river system focused mainly on forest and wetland areas, with only limited information available from agricultural soils. We carried out rainfall simulations on
The importance of terrestrial-derived organic matter for lake zooplankton communities remains debated, partly because little is known about the basic pathways by which allochthonous carbon is transferred to zooplankton, and whether these vary among the major taxonomic and functional groups. We quantified allochthony of three zooplankton groups (Cladocera, Calanoida, and Cyclopoida) across 18 lakes
Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystems and for Si export from soils to fluvial systems, effects of human cultivation on the Si cycle are still relatively understudied. Here we examined stable Si isotope (delta Si-30) signatures in soil water samples across a temperate land use gradient. We show that - independent of geological and climato

The study investigated how the political process of the Women, Peace and Security (WPS) agenda differs between South Korea and Sweden. Through the document analysis and the expert interviews, the research explored the formal and informal institutional dynamics that influence the development and implementation of National Action Plans (NAPs) and the WPS agenda. Also, it explored internal and extern
In scholarly literature, it is widely acknowledged that ‘the shadow of hierarchy’, hence the threat of disadvantageous Community legislation, is an important con-cept in European social dialogue (ESD), where European social partners – that is organised labour and management – are given the chance to negotiate binding agreements on some aspects of European labour and social policy. While the shadow
The following report contains a study over what happens with the proposals for action that is presented in fire investigations. Literature, 105 fire investigations and interviews were used to gather information. The literature shows that proposals for action are a natural conclusion in almost all investigation methods but little over half of the fire investigations present them and only a few had
Cities worldwide face unprecedented challenges, demanding innovative approaches to sustainable urban development. The imperative for cities to be dense and green poses significant challenges in urban planning, underscoring the need to understand how these goals interact. This study examines the dense and green city vision in Malmö's planning documents through critical discourse analysis, focus
Kazuo Ishiguro's novel The Remains of the Day has garnered much discussion by literary theorists. Studies have primarily concerned themselves with the main character Mr Stevens and how he interacts with the complex situations around him. A frequent question is of his reliability, as there are indications that he does not give correct interpretations of events. This essay uses poststructuralist
Evangelical missionaries in Cambodia have a dual role as religious actor and development actor. This hybrid identity poses conceptual challenges for development actors, beneficiaries, and even missionaries themselves-- are they doing ministry or are they doing development? Through field observations and interviews in Phnom Penh with evangelical missionaries, this thesis examines how evangelism and
Aims: Understanding fine-grain diversity patterns across large spatial extents is fundamental for macroecological research and biodiversity conservation. Using the GrassPlot database, we provide benchmarks of fine-grain richness values of Palaearctic open habitats for vascular plants, bryophytes, lichens and complete vegetation (i.e., the sum of the former three groups). Location: Palaearctic biog
The purpose of this paper is to develop an approach to estimate peat accumulation rates (PAR) over recent decades based on the age and burial depths of roots from pine sapling and to use the newly developed approach to estimate spatial variations of PAR. To this end, we sampled 120 pine saplings growing in three plots at Rėkyva peatland in Lithuania and accounted for the microtopography around eac
The scope of the 2030 Agenda for Sustainable Development and its 17 SustainableDevelopment Goals is unprecedented. So is the broad ambition expressed in thisagreement. While the United Nations has rarely shied away from declaring farreaching policy aspirations in the past, the 2030 Agenda sets the bar high –possibly higher than it has ever been before, with ambitious goals to end hungerand poverty
This chapter focuses on the national level and studies interlinkages, institutional integration and policy coherence in the context of the 2030 Agenda for Sustainable Development and the Sustainable Development Goals. After defining key terms, the chapter reviews how perspectives on interlinkages have shaped a new discourse, followed by an analysis of the steering effects of the global goals on in
The ecological effects of mass-flowering crops on pollinator abundance and species richness of neighbouring habitats are well established, yet the potential evolutionary consequences remain unclear. We studied effects of proximity to a mass-flowering crop on the pollination of local co-flowering plants and on patterns of natural selection on a pollination-generalised plant on the Tibetan Plateau.
