Accurate estimates of trait evolvabilities are central to predicting the short-term evolutionary potential of populations, and hence their ability to adapt to changing environments. We quantify and evaluate the evolvability of herkogamy, the spatial separation of male and female structures in flowers, a key floral trait associated with variation in mating systems. We compiled genetic-variance esti
Background and Aims To predict the evolutionary consequences of pollinator declines, we need to understand the evolution of delayed autonomous self-pollination, which is expected to evolve as a mechanism of reproductive assurance when cross-pollination becomes unreliable. This involves estimating the costs of increased levels of selfing as well as those associated with floral senescence. Methods W
Background: Small-scale topographic complexity is a characteristic feature of alpine landscapes, with important effects on alpine plant distribution. Aims: We investigated the links between small-scale topographic complexity and resultant microclimatic heterogeneity, vascular-plant species richness and beta diversity, and realised niche width and trait variation of some target species. Methods: We
The reproductive-assurance hypothesis predicts that mating-system traits will evolve towards increased autonomous self-pollination in plant populations experiencing unreliable pollinator service. We tested this long-standing hypothesis by assessing geographic covariation among pollinator reliability, outcrossing rates, heterozygosity and relevant floral traits across populations of Dalechampia sca
PREMISE OF THE STUDY: Competition among pollen grains from a single donor is expected to increase the quality of the offspring produced because of the recessive deleterious alleles expressed during pollen-tube growth. However, evidence for such an effect is inconclusive; a large number of studies suffer from confounding variation in pollen competition with variation in pollen load. METHODS: In thi
Premise of research. Selfing rates in mixed-mating plant species are often found to fluctuate greatly across time and space. Environmentally induced changes in floral traits may mediate changes in selfing rates through several mechanisms, including direct effects via changes in traits influencing autofertility rates and indirect effects via changes in traits affecting the rate of pollinator visita
This article investigates the impact of climate policies on electoral support for governing parties in Sweden through mixed methods combining a sentiment analysis of news articles and regression discontinuities of voter support over time. The regression discontinuity models indicate that the effects of climate policies on government support are not robust and are spurious across different model sp
Precision medicine should aspire to reduce error and improve accuracy in medical and health recommendations by comparison with contemporary practice, while maintaining safety and cost-effectiveness. The etiology, clinical manifestation and prognosis of diseases such as obesity, diabetes, cardiovascular disease, kidney disease and fatty liver disease are heterogeneous. Without standardized reportin
BackgroundStudies have shown that the risk of new-onset heart failure (HF) is higher post-implant for patients receiving right ventricular pacing.ObjectiveThis study aimed to investigate incidence, risk factors and implications for long-term prognosis of new-onset HF in patients after pacemaker-implant.MethodsPatients without preexisting HF who received a pacemaker in Sweden during the period 2005
i Ferdinand von Schirachs pjäs GUD diskuterar författaren livets avslut. Frågor som behandlas är Vem tillhör våra liv? Vem beslutar om vår död? Vem är vi? Vem vill vi vara? I Mattssons efterord skriver hon om dessa frågor utifrån ett juridiskt perspektiv.
With current environmental changes, evolution can rescue declining populations, but what happens to their interacting species? Mutualistic interactions can help species sustain each other when their environment worsens. However, mutualism is often costly to maintain, and evolution might counter-select it when not profitable enough. We investigate how the evolution of the investment in a mutualisti
At COP27, Parties agreed to establish a fund for loss and damage. During the COP28 opening plenary, the Loss and Damage Fund was operationalised. Despite this progress, significant questions about access to funding remain unanswered. We engage with a key term in the decision texts–particularly vulnerable. How Parties frame and define the term ‘particularly vulnerable’ will influence funding alloca
People in the Majority World disproportionately experience Loss and Damage (L&D) related to climate change. Policymakers and researchers are exploring ways to address L&D. However, significant knowledge gaps remain, including how to address what has been termed Non-Economic Loss and Damage (NELD). We contribute to filling this knowledge gap by analysing the NELD people are experiencing and
Emerging research on civil society elites has highlighted the presence of elitist tendencies in European civil societies with a growing concentration of political and economic resources in the hands of small groups of major organizations and leaders. Building upon this strand of research, this article aims at studying the power stratification of Italian civil society-third sector through a systema
There is a lack of studies aiming to assess cellular a disintegrin and metalloproteinase-17 (ADAM-17) activity in COVID-19 patients and the eventual associations with the shedding of membrane-bound angiotensin-converting enzyme 2 (mACE2). In addition, studies that investigate the relationship between ACE2 and ADAM-17 gene expressions in organs infected by SARS-CoV-2 are lacking. We used data from
