Active suspensions of microswimmers such as bacteria or microalgae are found in oceans or lakes, and within living organisms, such as the human body. These suspensions can exhibit complex flow patterns and enhanced diffusion of passive tracer particles due to the advection from the long-ranged dipolar flow fields of the swimmers. The diffusion of tracers at varying radii is poorly understood but o

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

Malaria, caused by the protozoan parasite Plasmodium falciparum is responsible for about 600.000 death cases every year. Mainly affected are populations of subtropical countries in Africa and the largest groups of victims are children below the age of 5 years. The fast evolving drug resistances of Plasmodium against the the most pow- erful antimalarials threatens the successful containment of this

Background: The evidence on the impact of high sugar consumption on micronutrient dilution does not yet allow for the establishment of clear thresholds of consumption. To establish upper and lower limit intake thresholds for added sugar, more studies from different countries and multiple populations are needed. The aim of this study was to examine the association between the intakes of added sugar

In terms of its total population, Sweden is one of the countries with the highest proportion of immigrants in the EU. Several factors are critical in integrating immigrants, especially their economic security in a new country. This thesis examines the relationship between law enforcement and economic security for over- indebted immigrants. The primary purpose of this research is to explore the rel

Insect herbivory is one of the most important ecological processes affecting plant–soil feedbacks and overall forest ecosystem health. In this study, we assess how elevated carbon dioxide (eCO2) impacts (i) leaf level insect herbivory and (ii) the stand-level herbivore-mediated transfer of carbon (C) and nitrogen (N) from the canopy to the ground in a natural mature oak temperate forest community

Insect herbivores play important roles in shaping many ecosystem processes, but how climate change will alter the effects of insect herbivory are poorly understood. To address this knowledge gap, we quantified for the first time how insect frass and cadavers affected leaf litter decomposition rates and nutrient release along a highly constrained 4.3°C mean annual temperature (MAT) gradient in a Ha

Globally, water-saving irrigation plays a vital role in agricultural ecosystems to achieve sustainable food production under climate change. Irrigation under mulch (IUM) system has been widely used in modern agricultural ecosystems due to its high water use efficiency, but it remains unclear how each component of the water and energy processes responds to this agricultural management practice. Cur

The aims of the study were 1). to investigate the association between the potential risk factors including socio-demographic, lifestyle and DNA methylation and mental disorders in middle-aged women from a large population-based follow-up study, and 2). to estimate the risk score by combining the potential risk factors to examine the mental disorder's incidence. A total of 6461 women, aged 50-65 ye

Fatty acid biomarkers have emerged as a useful tool to quantify biomass of various microbial groups. Here we focus on the frequent use of the fatty acid 16:1ω5 as a biomarker for arbuscular mycorrhizal (AM) fungi in soils. We highlight some issues with current applications of this method and use several examples from the literature to show that the phospholipid fatty acid (PLFA) 16:1ω5 can occur i

The CORDEX Flagship Pilot Study ELVIC (climate Extremes in the Lake VICtoria basin) was recently established to investigate how extreme weather events will evolve in this region of the world and to provide improved information for the climate impact community. Here we assess the added value of the convection-permitting scale simulations on the representation of moist convective systems over and ar
