Bumblebee communities and their foraging resources were surveyed in south Swedish agricultural landscapes of contrasting complexity, defined by the size of arable fields and the amount of permanent grazed pastures. After the flowering of oilseed rape (OSR), simplified landscapes contained substantially less herbaceous flower resources and a lower proportion of perennials, compared to complex ones.
Although much attention has focused on the diversity of plant mating systems, only a few studies have considered the joint effects of mating system and sexual conflict in plant evolution. In mixed-mating Collinsia heterophylla, a sexual conflict over timing of stigma receptivity is proposed: pollen with a capacity to induce early onset of stigma receptivity secures paternity for early-arriving pol
Insect pollination, despite its potential to contribute substantially to crop production, is not an integrated part of agronomic planning. A major reason for this are knowledge gaps in the contribution of pollinators to yield, which partly result from difficulties in determining area-based estimates of yield effects from insect pollination under field conditions. We have experimentally manipulated
The species richness of flower-visiting insects has declined in past decades, raising concerns that the ecosystem service they provide by pollinating crops and wild plants is threatened. The relative commonness of different species with shared ecological traits can play a pervasive role in determining ecosystem functioning, but information on changes in abundances of pollinators over time is lacki
Agricultural intensification is recognised as a major driver of biodiversity loss in human-modified landscapes. Several agro-environmental measures at different spatial scales have been suggested to mitigate the negative impact of intensification on biodiversity and ecosystem services. The effect of these measures on the functional structure of service-providing communities remains, however, large
Resilience of ecological communities to perturbation is important in the face of increased global change from anthropogenic stressors. Monitoring is required to detect the impact of, and recovery from, perturbations, and before-after-control-impact (BACI) analysis provides a powerful framework in this regard. However, species in a community are not observed with perfect detection, and occupancy an
Background: Changes in soil organic carbon (SOC) stocks significantly influence the atmospheric C concentration. Agricultural management practices that increase SOC stocks thus may have profound effects on climate mitigation. Additional benefits include higher soil fertility since increased SOC stocks improve the physical and biological properties of the soil. Intensification of agriculture and la
Natural enemies such as predatory arthropods and parasitoids have the potential to suppress pest species and provide the ecosystem service biological control. When predicting the potential of biological control in agriculture it is important to give evidence on how agricultural management influence the abundance and functions of the natural enemies. In this study we examined whether managements pr
The scientific literature on health effects from dampness in buildings, including mite exposure over the period 1998-2000 has been reviewed by a European group (EUROEXPO) of eight scientists in experience from medicine, epidemiology, toxicology and engineering. Forty studies deemed relevant have been the foundation for the conclusions. Dampness in buildings is a risk factor for health effects amon
Syfte: Uppsatsen behandlar begreppen organisationsprofil och organisationsidentitet. Syftet är att genom en fallstudie undersöka begreppens innebörd och relevans. Följande frågeställningar ligger som grund för undersökningen: - Vilken bild vill företaget förmedla av sig själv (profil)? - Vilka är de anställdas bild av företaget (identitet)? - Vilka likheter och skillnader finns det mellan företage
The aim of this study is to understand whether globalization has any effects on modern democracy and if so to see whether it can be replaced by something else – something larger than democracy within the nation-state. The aim was also to find out whether a cosmopolitan democracy is possible among nation-states with the help of cosmopolitan theory. In order to receive this information the author ha
I min uppsats har jag valt att undersöka hur pappan gestaltas i några utvalda bilderböcker från 2000-talet. Jag ville även undersöka vad fadern gör tillsammans med barnet och vilka uppgifter han utför i hemmet samt vilka attribut hos fadern som var särskilt återkommande. Ett noggrant urval utmynnade i 30 stycken böcker som sedan undersöktes och sammanställdes både kvalitativt och kvantitativt. I d
Självkonkordansmodellen (The Self-Concordance Model) postulerar att autonom målsättning är en primär drivkraft för välbefinnande. Standardiserade mätmetoder sammanblandar dock ofta närvaron av autonomi med frånvaron av yttre press genom användandet av 'relativa' differenspoäng. Denna studie använde ett aggregerat dataset (N = 429) för att systematiskt pröva två konkurrerande modeller: en BThe Self-Concordance Model posits that autonomous goal pursuit is a primary driver of well-being, yet standard measurement practices often conflate the presence of autonomy with the absence of external pressure via 'relative' difference scores. This study utilized a high-powered dataset (N = 429) to systematically test between a Balance Model (where meaning arises from the net difference b
The thesis describes and analyzes individuals' experiences of reduced working hours with retained salary, as well as how this could potentially enable an improved work-life balance. It also investigates how participants experienced pros and cons with reduced working hours. The topic is relevant due to the ongoing societal debate about whether the current 40-hour workweek in Sweden shoul
This thesis aimed to explore the binding pocket of galectin-8N and galectin-3C. Both structure-based drug design and fragment-based drug discovery were utilized in this project, exemplifying the benefits of the different approaches. Structural determination of the proteins in complex with both high affinity ligands, and small fragments was achieved through x-ray crystallography. The structures of
It has for long been known that dark matter must exist in our universe. Despite massive efforts to detect dark matter, its constituents remain a mystery. One strategy to unveil this mystery is to produce dark matter by colliding Standard Model particles. The most common signature of dark matter production is an excess of missing transverse energy, MET. Such an event would be very rare, which is wh
This paper contributes to sustainability transitions studies in delivering stronger focus and relevance on culture and discursive features to apprehend social resistances towards transition agendas, and the unprecedented emergence of the challenging antagonism of the ‘end of the world’ versus ‘the end of the month’ revealed by the case study of the Yellow Vests crisis in France since November 2018
With the rapid diffusion of short video social media, a wave of rural influencers has emerged on China’s TikTok (Douyin), using short-form content to build personal brands and engage in sociocultural expression. Anchored in practice theory (Shove et al., 2012), this study adopts the “material–competence–meaning” triadic model to examine how these rural creators strategically construct personal bra
