The otter (Lutra lutra) is a cryptic, semi-aquatic mustelid, with several uncertainties regarding its ecology and reproductive success in Sweden. To ensure future conservation, distribution and population estimates are needed and the ecological knowledge gaps must be filled in. This study aimed to examine three ecological factors possibly related to the occurrence and distribution of the Scanian o
Across Europe, breeding bird species are decreasing in several types of habitats. Deciduous forest specialist birds are facing a loss of habitat due to the forest management that removes important key components in the forest, e.g. dead wood. Already in Sweden three woodpecker species that are deciduous forest specialist have decreased in population: one has become locally extinct (middle spotted
This study aims to examine whether sustainable firms are more sensitive to economic hardship such as an economic crisis, high inflation and low GDP-growth than companies with less focus on sustainability. The research is based on publicly available taxonomy scores of twenty-three of largest publicly traded stocks in Sweden between 2003-2023. The results from three regressions, based on the same mo
The northern pike Esox Lucius is a highly sought-after resource targeted by recreational anglers but now declining. In the Baltic Sea the species consist of two sympatric populations residing in the shallow coves. However, with difficulties to assess the relatively stationary species, this project aimed to bring to light important factors of pike habitats using a new method of electrical fishing b
The European pond turtle (Emys orbicularis) is a redlisted freshwater turtle species and a protected species in France. It is relying strongly on immerged habitats for most of its active life cycle, but depends also on land habitats for egg deposition. As most wetland species, it is undergoing severe pressures due to the reduction and degradation of its habitats. In the Mediterranean, rises in sal
Stormwater pollution is known to alter river water quality, but its impacts on aquatic biodiversity remain poorly understood. This study investigates the effects of stormwater runoff on water quality and benthic macroinvertebrate communities in the Rönne å river, southern Sweden. A field-based study was conducted in rural and urban river sections, comparing pipe discharge sites with nearby referen
Denna studie undersöker sambandet mellan variablerna arbetskrav, organisationskultur och socialt stöd, på utfallsmåttet, benägenhet till sjuknärvaro. Med avsikt att upptäcka viktiga insikter inriktade sig studien på följande delar: kvantitativa krav, känslomässiga krav, socialt stöd från överordnade, socialt stöd från kollegor, tillit och trovärdighet mellan ledning och anställda samt tillit och tThis study investigates the relationship between the variables work demands, organizational culture and social support, on the outcome measure, presenteeism. With the intention of discovering important insights, the study focused on the following parts: quantitative demands, emotional demands, social support from superiors, social support from colleagues, trust and credibility between management
Nesting phenology in birds has been studied for decades and two different breeding strategies have been identified, income and capital breeding. The nesting behaviour and the breeding strategies of 131 females were studied from three species, the Common eider (Somateria mollissima) (n = 65), known to be a capital breeder and two species the Velvet scoter (Melanitta fusca) (n = 48) and the Red-brea
Climate change driven increases in temperature are predicted to enhance oxidative stress as well as to accelerate telomere shortening and thus ageing in ectotherms. Understanding if and how populations can adapt to environmental stressors by altering telomere dynamics and decelerating the ageing process is therefore of major concern. I approached this question by taking advantage of two naturally
Protein biosynthesis follows a hierarchical process, as genes are transcribed into mRNA, translated into a chain of amino acids, and ultimately folded into functional proteins. This implies that the protein structure is merely determined by the amino acid sequence. Yet, studies on translation efficiency indicate that codon usage, which is organism dependent, significantly impacts protein folding k
Vi alla har sett dem! Tomma hus som en gång varit trygga hem men som förvandlats till byggnader i förfall. Ofta ligger de på vackra platser, byggda med gedigna material och med lång och händelserik historia. Vi pratar såklart om alla övergivna hus som finns i Sverige. Hus som tappat sitt syfte men inte sin själ. Hus som skulle kunna ses som en resurs i den viktiga klimatomställningen och som en deWe have all seen them! Empty houses that were once safe homes but have now turned into buildings in decay. Often located in beautiful places, built with solid materials and rich in history. We are talking about the many abandoned houses found throughout Sweden. Houses that have lost their original purpose but not their soul. Houses that could be seen as a resource in the important climate transiti
The thesis examines the impact of the Trump and Biden administrations on international trade relations and agreements, specifically comparing their trade policies. It explores how their contrasting approaches—Trump's protectionist stance versus Biden's multilateral cooperation—have influenced global trade dynamics through a mixed-methods approach for analysis. The research incorporates bot
As the number of devices connected via 5G has grown tremendously over the years since its introduction, the number of unused frequency spectra has grown smaller and smaller, leading to more overlap and smaller gaps between neighbouring spectra. To ensure that all current and future devices that occupy these spectra can work together without interference or interruptions in service, care needs to b
Introduction: Asthma, a heterogenous respiratory disease that affects 300 million people, is characterized by coughing, chest tightness, airway inflammation, and shortening of breath. Asthma exacerbations are commonly triggered by viral infection, such as rhinovirus infection. Respiratory viral infections primarily target the epithelium resulting in the release of alarmins and proinflammatory cyto
Soil temperature fluctuations are typical at high latitudes in early spring or late autumn. Freeze-thaw cycles (FTCs) occur when the soil temperature fluctuates around 0°C, causing a change in the state of the soil solution. Due to climate change, FTCs are predicted to become more frequent and intense, especially in the Arctic, Antarctic, and cold temperate regions. In this study, two experiments
This study aims to investigate if inflexible investment agreements limit countries’ environmental ambition, mainly focusing on the potential existence of regulatory chill. A panel dataset of 54 countries covering the years from 2008 to 2023 is used to examine the relationship. The analysis employs a fixed effects regression model, initially applying the Environmental Kuznets Curve theoretical fram
This report describes the implementation and evaluation of COMSOL Multiphysics’ ability to simulate the thermomechanical response of a package material. The project was partitioned into three main parts. First, a quantitative assessment of COMSOL’s accuracy in modeling the large strain elastoplastic response of paperboard was con- ducted. Second, an evaluation was performed of COMSOL’s capability
Work-life balance är ett arbetsmiljöproblem som är av ökande relevans på både organisations- och individnivå. Ämnet är särskilt relevant för gymnasielärare, ett yrke som har sett en ökad grad av utbränning och långtidssjukskrivning under de senaste åren. Studien syftar till att analysera hur gymnasielärares fritid, arbete och work-life balance hänger samman och påverkar varandra och ifall det finnWork-life balance is a workplace issue that is increasing in relevance at both the organizational and individual levels. The topic is particularly relevant for high school teachers, a profession that has seen a rise in burnout and long-term sick leave in recent years. The study aims to analyze how high school teachers free time, work, and work-life balance are interconnected and influence each oth
The aim of this bachelor’s thesis is to examine whether, to what degree and in what pattern physical activity differed between medieval men of differing social status. An overall purpose of this was to test whether, and to what degree the purported warrior culture of the medieval nobility had on its manual physical activity. This was tested by examining the patterns of humeral midshaft bone geomet
