AimClimate change is currently altering the geographical distribution of species, but how this process contributes to biogeographical variation in ecological traits is unknown. Range-shifting species are predicted to encounter and respond to new selective regimes during their expansion phase, but also carry historical adaptations to their ancestral range. We sought to identify how historical and n

Successful innovation strategy relies on experience gained from a complexity of understanding, anticipating and managing the global business environment. But, although much research has examined strategies of private sector organizations in Western economies, there are relatively few studies of innovation in public sector organizations of transitional and protected economic environments, such as I

This paper examines the impact of inflation on the income tax in Spain from 1979 to 1987. By introducing a new approach using dynamic microsimulation and the Elasticity of Taxable Income (ETI), we analyze three dimensions of the tax: revenue, progressivity, and redistribution. The microsimulation reveals that the lack of adjustment of the income tax to inflation: 1) accounts for 44% of the increas

I det svenska samhället syns en nedåtgående trend när det gäller barn och ungas läs- och skrivförmåga. Därmed finns det ett värde i att utforska effekter av läsfrämjande initiativ. Den aktuella studien ämnar således att studera vilken betydelse miljön på kulturhuset Funnys Äventyr kan ha i relation till högläsning. Mer specifikt undersöks vilken betydelse miljön har för barns nivå av distraktion o

Many ectothermic species are currently expanding their distributions polewards due to anthropogenic global warming. Molecular genetic mechanisms facilitating range expansion under these conditions are largely unknown, but understanding these could help mitigate expanding pests and disease vectors, or help explain why some species fail to track changing climates. Here, using RNA-seq data, we examin

Disentangling the relative importance and potential interactions of selection and genetic drift in driving phenotypic divergence of species is a classical research topic in population genetics and evolutionary biology. Here, we evaluate the role of stochastic and selective forces on population divergence of a colour polymorphism in seven damselfly species of the genus Ischnura, with a particular f

A bacterial community may be resistant to environmental disturbances if some of its species show metabolic flexibility and physiological tolerance to the changing conditions. Alternatively, disturbances can change the composition of the community and thereby potentially affect ecosystem processes. The impact of disturbance on the composition of bacterioplankton communities was examined in continuo

The years 2023 and 2024 were characterized by unprecedented warming across the globe, underscoring the urgency of climate action. Robust science advice for decision makers on subjects as complex as climate change requires deep cross- and interdisciplinary understanding. However, navigating the ever-expanding and diverse peer-reviewed literature on climate change is enormously challenging for indiv

Bird embryos develop inside eggs, which contain maternal substances that can shape offspring phenotype and fitness. Yolk fatty acids are a key energy source for the developing embryo, with omega-6 (ω-6) and omega-3 (ω-3) polyunsaturated fatty acids (PUFAs) obtained exclusively from the diet. Therefore, food availability during the breeding season is expected to influence yolk fatty acid compositio

Increasing tree species diversity is known to enhance soil organic carbon (SOC) stocks, but its effect on SOC stability remains a critical uncertainty for climate mitigation. Through examination of a subtropical karst forest diversity gradient in southwest China, we reveal a fundamental shift in SOC stabilization mechanisms using physical fractionation, 13C nuclear magnetic resonance spectroscopy

Straw addition is a widely used agricultural practice to maintain soil fertility. However, its effects on soil organic carbon (SOC) and nutrient cycling are complex, with outcomes ranging from inhibition to stimulation of SOC mineralization via the priming effect. Freeze-thaw cycles are common disturbances in agroecosystems of high-altitude regions that are predicted to increase in frequency and s

Anthropogenic elevated atmospheric carbon dioxide (eCO2) increases carbon (C) availability to plants. Whether ecosystems store or release this additional C depends on the balance between net primary production (NPP) and soil respiration, where eCO2-stimulated NPP can be constrained by the provisioning of nutrients by microbial decomposers. Ecosystems gradually become more phosphorus (P)-limited as

Background: Improving stroke services is critical for reducing the global stroke burden. The World Stroke Organization–World Health Organization–Lancet Neurology Commission on Stroke conducted a survey of the status of stroke services in low and middle-income countries (LMICs) compared to high-income countries. Methods: Using a validated World Stroke Organization comprehensive questionnaire, we co
