Climate change has the potential to affect the ecology and evolution of every species on Earth. Although the ecological consequences of climate change are increasingly well documented, the effects of climate on the key evolutionary process driving adaptation - natural selection - are largely unknown. We report that aspects of precipitation and potential evapotranspiration, along with the North Atl
The Crabtree positive yeasts, such as Saccharomyces cerevisiae, prefer fermentation to respiration, even under fully aerobic conditions. The selective pressures that drove the evolution of this trait remain controversial because of the low ATP yield of fermentation compared to respiration. Here we propagate experimental populations of the weak-Crabtree yeast Lachancea kluyveri, in competitive co-c
Although reports of pharmaceutical bioconcentration in aquatic organisms are increasing, less is known about trophic transfer in aquatic food webs. The bioaccumulation and trophodynamics of sertraline and fluoxetine, 2 selective serotonin reuptake inhibitors (SSRIs) frequently detected in aquatic environments, were tested by exposing constructed aquatic food chains to SSRIs under controlled labora
Abstract Sedentary behavior is defined as sitting or lying with low energy expenditure. Humans in industrialized societies spend an increasing amount of time in sedentary behaviors every day. This has been associated with detrimental health outcomes. Despite a growing interest in the health effects of sedentary behavior at work, associations remain unclear, plausibly due to poor and diverse methodSedentary behavior is defined as sitting or lying with low energy expenditure.

Manufactured surfaces usually consist of topographical features which include both those put forth by the manufacturing process, and micro-features caused by disturbances during this process. Surface characterization basically involves study of these features which influence the functionality of the surface. This article focuses on characterization of the surface topography of machined lead brass
There is a growing need for selective recognition of microorganisms in complex samples due to the rapidly emerging importance of detecting them in various matrices. Most of the conventional methods used to identify microorganisms are time-consuming, laborious and expensive. In recent years, many efforts have been put forth to develop alternative methods for the detection of microorganisms. These m
Purpose We validate the usefulness of laser-induced autofluorescence for the detection of bladder carcinoma. Materials and Methods We obtained and analyzed fluorescence spectra from 75 patients in whom bladder cancer was suspected. Tissue fluorescence was excited by a nitrogen laser using a quartz optical fiber placed in gentle contact with the area of interest. The laser-induced autofluorescence
This dissertation consists of three empirical essays concerning social norms and their effect on economic outcomes. Each essays discusses a seperate subject.

Abstract: Long-term monogamy is a key characteristic of family living across animals. The evolutionary maintenance of long-term monogamy has been suggested to be facilitated by increased reproductive coordination as a result of mate familiarity, leading to increased reproductive success. However, such effects can be compromised if females mate outside the pair bond (e.g. female polyandry), introdu
Denna studie har syftat till att kartlägga allmänbefolkningens exponering för vissa luftburna cancerframkallande ämnen: bensen, 1,3-butadien, formaldehyd, kvävedioxid, kväveoxid samt ozon. Undersökningen genomfördes i Malmö under hösten 2014 och inkluderade totalt 42 slumpvis utvalda malmöbor i åldrarna 20-50 år. Samtliga mätningar, bortsett från formaldehyd, upprepades på 22 personer. Tjugo av de
This paper combines new archival data on women’s wages from southern Sweden with published series from Stockholm in order to create a series of early modern female construction workers’ wages between the middle of the sixteenth and middle of the eighteenth centuries. This paper finds that women had relatively high relative wages in the later part of the sixteenth century, with an increasing wage g
Small heat shock proteins (sHSPs) are present in all kingdoms of life and play fundamental roles in cell biology. sHSPs are key components of the cellular protein quality control system, acting as the first line of defense against conditions that affect protein homeostasis and proteome stability, from bacteria to plants to humans. sHSPs have the ability to bind to a large subset of substrates and
Cardiovascular diseases are the leading cause of death worldwide. In order to improve the diagnostics and facilitate early interventions of cardiovascular diseases, knowledge about the physiology of the vascular system in both healthy subjects and in subjects with vascular disease is needed. In order to learn more about the physiology of the vascular system and possibly predict cardiovascular dise
