This study investigates spatiotemporal changes in eelgrass (Zostera marina) extent in Skälderviken between 2006 and 2023, and compares these changes with riverine nutrient loads, modelled water-quality indicators and depth distribution. Eelgrass extent was mapped from orthophotos and high-resolution satellite imagery for 2006, 2010, 2016 and 2023. Annual nitrogen and phosphorus loads from Rönne å
This study examines challenges and solutions for biodiversity conservation in privately owned forests in Skåne in southern Sweden. The study is conducted in response to the increasing number of threatened forest-dependent species due to production-oriented forestry. Since private forest owners are a central part of forest management in Sweden, their priorities and management decisions directly inf
Climate change increasingly affects urban areas through heatwaves, flooding and extreme weather events, while previous research shows that these impacts disproportionately affect vulnerable and marginalized groups. Therefore, integrating justice into climate adaptation planning has become an increasingly important issue in both research and policy. This study analyzes how four justice dimen sions
Locknekratern i Jämtland, centrala Sverige bildades för cirka 455 miljoner år sedan i ett grunt epicontinentalt hav när en meteorit med en diameter på 600 meter slog ner i den Baltiska skölden. Nedslaget skapade en 7.5 km bred inre krater i det proterozoiska kristallina urberget som överlagrades av skiffer och kalksten. Eftersom den ursprungliga morfologin hos nedslagskratrar snabbt eroderas på joThe Lockne impact structure in Jämtland, central Sweden, was formed approximately 455 Ma in a shallow epicontinental sea when a bolide 600 meters in diameter struck the Baltic Shield. This event excavated a 7.5 km wide inner crater in the target rocks at the site, comprised by Proterozoic crystalline basement overlain by shale and limestone. Since the original morphology of impact craters are rapi
Tidigare studier har visat en minskning av artrikedom i tundraekosystem i norra Fennoskandien, vilket innebär en betydande risk för ekosystemens funktion samt för renskötselns betesmarker. I samband med klimatförändringar och ökad mänsklig aktivitet är det därför viktigt att undersöka sambandet mellan artrikedom, aktuella och historiska miljöförhållanden samt antropogen påverkan. För att adresseraPrevious studies have shown a recent decline of vegetation diversity across tundra ecosystems in Northern Fennoscandia, posing a significant risk to ecosystem functioning and reindeer grazing. In the context of climate change and increasing human activities, it is essential to evaluate the nexus between vegetation diversity, current and historical environmental conditions and human impact. Address
The planet is facing one of its biggest challenges yet, climate change. Coastal flooding and erosion are some of the severe climate change effects that society is forced to handle. Climate adaptation needs to be addressed at a regional or a local level where the effects are experienced. Previous research has mostly focused on identifying which factors hinder or facilitate climate adaptation on a l
The Copernicus High Resolution Vegetation Phenology and Productivity product (HR-VPP) has been operational for several years and has been used by various institutions to assess crop growth conditions and estimate crop yield. However, studies focusing on winter-growing crops, especially winter wheat, remain limited. HR-VPP is based on the Plant Phenology Index (PPI). In theory, PPI is expected to p
Foodborne diseases are a growing global concern, and a shift in trends has occurred regarding salmonella infections in Sweden. The purpose of this study is therefore to investigate how nursing homes in Sweden work to prevent foodborne infections. The study was conducted through semi-structured interviews with staff at nursing homes and with representatives from inspection authorities to gather the
Water reservoirs fulfill numerous functions for ecosystems and society. They are crucial for flood control, hydrological cycles, and biodiversity. Knowledge about the storage capacity is useful for adaptive water management, risk assessment, and hydrological modeling. In-situ measurements of reservoir storage capacity are challenging due to the high financial and temporal costs of field survey, wh
Cyanobacterial blooms and bottom-water hypoxia have long been studied and connected to the eutrophication in the Baltic Sea. This thesis investigates the dynamic of the spatiotemporal correlation between cyanobacterial summer bloom and dissolved oxygen at the sea floor in the Western Gotland Basin, as per defined by HELCOM 2022. The thesis is conducted using weekly and monthly data from 1998 to 20
Pork makes up around 30 % of the overall meat consumption. Pig production has an impact on the environment, and its impact depends mainly on the feed used. Agriculture in general has impacts both on the climate and biodiversity. Since animal products’ consumption are increasing it is of interest to assess its environmental impact. This study aims to assess two pig feeds’ environmental impact throu
Administrative environmental sanctions is a regulatory tool that plays a key role within Swedish environmental supervision, and its implementation often falls on municipal environmental and health inspectors. The system operates around the premise that specific offenses are combined with set fees, thus theoretically removing the need for complex judicial assessments. This study examines the experi
Benthic foraminifera are valuable environmental indicators, as species assemblages can vary depending on their surrounding marine conditions. Previous studies have reported the potentially invasive Nonionella sp. T1 along the Swedish west coast, a non-indigenous species (NIS) with abilities to denitrify and adapt to varying environments. In this thesis, with the aim of studying foraminiferal speci
Passive immunotherapy targeting amyloid-β (Aβ) has emerged as a major therapeutic strategy for Alzheimer’s disease (AD), yet its clinical benefits remain modest and are frequently accompanied by vascular adverse events such as amyloid-related imaging abnormalities (ARIA). While the removal of extracellular Aβ plaques is associated with therapeutic efficacy, accumulating evidence suggests that addi
As global population growth drives up food demand, approximately 40% of produced food is still wasted rather than consumed. This waste is largely driven by rigid aesthetic and quality requirements established by marketing standards, resellers, and consumer expectations. This study was conducted to investigate those systemic barriers and how it affects waste reduction within the organization that i
Objective – This study aimed to characterize the occurrence of hypogammaglobulinaemia (HG) in rituximab (RTX)-treated patients with ANCA-associated vasculitis (AAV) in a population-based Swedish cohort. Methods – Patients with incident AAV (1997–2019) in southern Sweden who received RTX for induction or maintenance therapy were included in this study. Medical records were reviewed to assess the in
Nurses are in need of effective sterile packaging for transporting, storing, handling, preparing and disposing of single use medical devices. At the same time, requirements surrounding sustainability are mounting both from a regulatory and user perspective. Producers need to develop more sustainable options for hospitals with a great variation in waste management practices while not impeding on th
River water levels and river discharge are key hydrological variables for flood risk assessment, water resource management, drought monitoring and climate change research. However, in-situ river measurements are lacking, and globally many rivers remain ungauged. Satellite altimetry offers an alternative approach to water surface measurement by providing river observations from space. The Surface W
Systemidentifiering handlar om att skapa modeller som beskriver ett system utifrån mätningar. Fokus i den här texten ligger på dynamiska system som styrs av ordinära differentialekvationer. Avvägningen mellan en noggrann modell och en modell som ̈ar lätt att förstå, tas upp. Metoden SINDy bygger på att konstruera ett bibliotek av funktioner som används för att optimera f i ekvationen x’ = f(x).
