Colour clines constitute an interesting topic of study for evolutionary ecologists as they allow for the testing of different hypotheses on the adaptive value of colour variation. One possible explanation for the selective advantage of colouration is crypsis. In Littorina saxatilis from the Rías Baixas (northwest Iberian Peninsula), a temporally stable and spatially recurrent colour cline has been
Our book has taken a distinctive, policy-oriented approach to IGR in analysing both specific crisis-driven problems and new, longer-term, and emerging policy issues confronting European governments. We have explored the shifting balances of power within IGR systems focused on the challenges of vertical and horizontal coordination within cross-country, comparative perspectives. In order to position
Background: Staphylococcus aureus bacteraemia (SAB) may lead to periprosthetic joint infections (PJI) via haematogenous spread of bacteria to the joint. Due to the risk of PJI, patients with SAB and prosthetic joint are recommended prolonged antibiotic treatment. The aim of the study was to assess the risk of PJI during SAB, and to evaluate if short treatment duration affects outcomes in patients
Säkerheten om demokratins robusthet har gett vika för en allmänt diagnostiserad demokratikris. Allt fler röster höjs för att försvara de demokratiska institutionerna mot dem som vill avskaffa dem på formellt demokratisk väg. Men för att värna demokratin, hävdas det, krävs paradoxalt nog att man håller tillbaka den demokratiska omvandlingen. I denna avhandling hävdas att denna ”demokratiska paradoCertainty about the robustness of democracy has given way to a widely diagnosed crisis of democracy. There are increasing calls to defend democratic institutions against those who seek their formally democratic abolishment. But safeguarding democracy, it is argued, paradoxically requires restraining democratic transformation. This dissertation argues that this ‘democratic paradox’ is misconceived.
Identifying lake reference conditions is a crucial task for successful lake restoration. A common method is the paleolimnological approach. However, lakes can be influenced by multiple stressors over time, making it necessary to consider possible combined effects. In this study, we aimed to untangle the interpretation of subfossil Cladocera in relation to different environmental parameters in lake
BackgroundIn 2015, a selective decrease in the glomerular filtration of middle-sized molecules such as cystatin C compared to small molecules such as creatinine was first described and tentatively termed “Shrunken pore syndrome.” Numerous studies have thereafter found an association between this syndrome (defined by a low eGFRcystatin C to eGFRcreatinine ratio) and mortality and morbidity. In 2023
BackgroundChildren with chronic diseases are reported to have increased risk of psychiatric comorbidity. Few studies have investigated this risk in juvenile idiopathic arthritis (JIA), with conflicting results. We performed a population-based, longitudinal cohort study of the risk of depression and anxiety in south-Swedish patients with juvenile arthritis.MethodsThe south-Swedish JIA cohort (n = 6
Predation is a major evolutionary driver of animal adaptation. However, understanding of anti-predator evolution is biased toward vertebrate taxa. Cephalopoda, a class in the invertebrate phylum Mollusca, are known for their diverse anti-predator strategies, characterised by their behavioural flexibility. While ancestral cephalopods were protected by a hard outer shell, extant cephalopods have gre
Urban pluvial flooding is a growing climate-related risk in Nordic cities, where short-duration rainfall extremes interact with aging drainage infrastructure and urban form. This study analyses 17 years (2006–2023) of property-level basement flooding reports from Trelleborg, a coastal municipality in southern Sweden, to identify empirical rainfall thresholds and infrastructural conditions associat
Populärvetenskaplig sammanfattning: För att öka tillgången på mat och att generera arbeten och inkomster är det angeläget för utvecklingsländer att öka produktionen inom jordbruket. En förutsättning för detta är att eliminera produktionshinder genom att dels förbättra jordbruksmetoder, dels identifiera olika områden som är lämpliga för olika typer av jordbruk. Denna Minor Field Study (MFS) är utföThe importance of less developed countries to increase the agricultural production, in order to improve food supplies and generate employment and income, requires the removal of resources constraints by improving agricultural practices and identifying land suitable for different agricultural activities. This Minor Field Study (MFS) is made within the present Sida/SAREC-financed research project “R
The crucial goal of kidney-sparing surgical resection of a malignant tumor is complete removal of the cancerous tissue. The exact border between the cancerous and normal tissues is not always possible to identify by naked eye, therefore, a supplementary intraoperative diagnosis is needed. Unfortunately, intraoperative pathology methods used nowadays are time consuming and of inadequate quality ren
The TCF4 gene encodes for the basic helix–loop–helix transcription factor 4 (TCF4), which plays an important role in the development of the central nervous system (CNS). Haploinsufficiency of TCF4 was found to cause Pitt-Hopkins syndrome (PTHS), a severe neurodevelopmental disorder. Recently, the screening of a large cohort of medulloblastoma (MB), a highly aggressive embryonal brain tumor, reveal
This thesis contributes to empirical research in labor economics. It consists of three self-contained papers.The first paper, The Effect of Paid Vacation on Health: Evidence from Sweden, analyzes the causal effect of paid vacation on health. Using register data on the universe of central government employees in Sweden, I exploit an age-based rule stipulated in the collective agreement covering the
Background: Many translational MR biomarkers derive from measurements of the water proton longitudinal relaxation rate R 1 , but evidence for between-site reproducibility of R
The DNA sequencing of a series of living organisms has elucidated many biological problems. But the internal atomic and electronic evolution of DNA remains to be mapped in detail. RNA and DNA now appear to be the prime determinants of biological evolution leading to the sudden appearance of novel organism structures and functions that emerge “ready made” as a surprise to the organism. This has bee
In the early 1980s many social theorists claimed that the ‘New Social Movements’ (NSMs) were the authentic social movements of our time. This claim is discussed in relation to two traditions in the analysis of social movements. The ‘American’ tradition focuses on the single-issue movement of a protest and mobilizing character. The ‘European’ tradition focuses on the relation between major societa
We have built a system dynamics model, WORLD6, that takes into account population, energy extraction, production and need, aspects social behaviour, material and metals recycling and important links to the economy. The model is ground-truthed by comparing with actual supply per person from 1900 till 2015 and run until 2400. Primary scarcity metrics are supply per person and year and stock-in-use p
