The genetics underlying bird migration have been the subject of several studies. Two willow warbler subspecies (Phylloscopus trochilus trochilus and Phylloscopus trochilus acredula) follow different routes during their winter migration to Africa. Their breeding territories overlap in a contact area or “migratory divide” across central Scandinavia and to the east of the Baltic sea. Previous genome-

It is well established that bumblebees play a vital role in the ecosystem, not only as pollinators but as providers of other ecosystem services. Thus, it is important to have a good understanding of their habitat requirements and ecology. Bumblebees can learn to associate floral cues with rewarding and unrewarding flowers. The availability of resources in flowers is very dynamic as it varies durin

This study is centred around Fridays for Future, a youth movement which has rippled across the world from its first sparks in the fall of 2018 to the spring of 2019, and has given rise to countless pieces about the movement in both traditional and social media. According to critical discourse theory, the discourses that we read in the media both affect us and how we see things, but the context in

Conflict-related sexual violence should not be regarded just a symptom of war or evidence of its violent excess. It is criminalised as a violation of international law, as a war crime, a crime against humanity and, in some cases, as a component of genocide. It brings overwhelming social, psychological and economic consequences to survivors, families, communities and nation states. Conflict-related

Paleoekologiska studier har visat sig vara ett bra verktyg för att studera trädetablering, samt dess relation till klimatpåverkan och mänsklig påverkan. Utbredningen av Picea i Sverige under Holocen är väldokumenterad, men kunskapsluckor kring dess spridningsdynamik kvarstår. Denna studie ämnar tydliggöra Piceas etablering i en lokal i sydvästra Sverige, och därpå även bidra till kunskapsbasen om Paleoecological studies have shown to be a good tool for studying the establishment of trees, as well as their relation to climate and human influence. The spread of Picea in Sweden during the Holocene is well documented, but knowledge gaps concerning the spread dynamics still remains. This study aims to clarify the establishment of Picea in a locality in southwestern Sweden, and thereby also cont

Given a pollen data set from Europe over a time period, the aim is to reconstruct the past land cover by interpolating from the pollen data values to a continuous map. The data is on compositional form with three vegetation categories; coniferous forest, broadleaved forest and open land. Reconstruction will be based on a Gaussian Markov random field with separable spatio-temporal structure for the

This thesis describes attempts at estimating the uncertainty of the 2-metre temperature forecast error from a probabilistic point of view, utilizing Bayesian neural networks. Bayesian neural networks are a type of machine-learning algorithms used to find patterns in data and make probabilistic predictions. Multiple fields of output data from the ECMWF IFS global model, along with temperature measu

Integrering av historia i fysikundervisningen har undersökts länge och i stor omfattning internationellt. Det finns ett brett stöd för att det kan ha många önskvärda effekter på elevers lärande och motivation. Denna positiva bild verkar inte delas helt av fysiklärare och det framkommer att det finns många utmaningar med att integrera fysikhistoria i undervisningen. Syftet med denna uppsats var attIntegration of history of physics (HOP) in the teaching of physics has been studied for a long time and to a great extent. There is a widespread support of the fact that history of physics can have many desirable effects on students learning and motivation. This positive picture is seemingly not shared completely among physic teachers and to implement history to the physics classroom has been show

Vi lever idag i en tid av fundamental osäkerhet och striden får vi inte sällan höra står mellan de som går en osäker framtid till mötes och de som nostalgiskt blickar tillbaka. I Vellinge möter vi de som med vemod ser sin ort förändras till vad den inte tycks ha varit förut, liksom de som betraktar ortens utveckling i starkt positiva ordalag. Men vi möter också personer med olika materiella förutsThe following thesis examines two responses to processes of social change within the small town of Vellinge in the province of Scania, Sweden. The experiences of change within the town appear in the guise of two contradicting narratives – one of the town’s progress and the other of its decline – which I aim to approximate from nine in-depth interviews with eight inhabitants conducted in two cycles

Målet är att undersöka hur en ökad installation av solceller kommer att påverka lågspänningsnätet. Öresundskraft efterfrågade en rapport som undersöker framtida problem i deras nät när solcellssystem installeras i större omfattning. Scenarion där olika procentantal kunder i lågspänningsnätet installerar solceller har analyserats och simulerats. Två olika lågspänningsnät har används, ett område påThe goal of this report is to examine the impacts of integrating Photovoltaic systems in low voltage networks. Öresundskraft requested a report on what problems can arise in the future as more and more people start using PV systems. Scenarios where a certain percentage of an area will install PV systems have been simulated, as well as further analysis of the results from the simulations and calcul

This ethnographic study investigates the functions of BestFighter Muay Thai and Mixed Martial Arts training camp in Koh Samui, Thailand, as a successful actor in a booming self-improvement economy. In this thesis I explore the entanglements with locality and power which enable what satisfied participants refer to as augmented experiences of self-improvement. Combining theoretical concepts such as

Mukund Kabbe Oligodendrocyte differentiation in development and disease Oligodendrocytes (OLs) are cells that reside in the brain and spinal cord (collectively called the central nervous system (CNS)). They wrap the axons of neurons with a lipid-rich substance called myelin. Functionally, the myelin sheath around the axon is similar to the insulation around wires for electrical devices. It prov

My research thesis is a search for a place to be, a place that would make the city an easier place to live and experience, when we are either constantly surrounded by a tumultuous public or isolated at home. My search has led me to define a place that could provide simultaneously Space and Time to bridge what is missing in both the public and the private. What is there left, not linked to commerc

Since carbon-emitting energy sources are the largest contributor to global warming and climate change, this present paper attempts to contribute to the current debate in energy-growth nexus in the literature. Focusing on the case of Turkey, it seeks to find out whether or not switching to a low-carbon path will be beneficial for this fastest-growing OECD economy by investigating the relationship b

YouTube is today one of the most popular video hosting services on the Internet. With over a billion users all over the world it is an immensely active website. It is also a major platform for video content creators also referred to as YouTubers. These YouTubers, through their practice of content creating, can be said to be the heart and soul of this website. However, very little seems to be known

Although there is a well-researched theoretical tradition to explain institutional trust, very little research has been done in authoritarian countries in general, and MENA countries more specifically. This study aims to fill this gap in the literature by identifying the factors that explain institutional trust in Algeria, focused more specifically on Algeria’s armed forces as one of the powerbrok

Lately, there has been a world-wide increase in the awareness of animal cruelty e.g. in the entertainment business, meat industry, in the scientific community, and among people in general. This has called for a scrutiny of how we treat animals and in the scientific community it has stimulated research to reduce animal experiment. Experimental systems usually considered animal cruelty free, like ce
