This master thesis investigates the synthesis, structural characterization and electrochemical performance of copper(II) oxide (CuO) and cobalt-doped CuO nanofibers as electrocatalysts for the electrochemical nitrate reduction reaction (NO3-RR). The overarching aim is to assess their potential for sustainable ammonia production under ambient conditions. A series of exploratory synthesis trials rev

There are fungi whose delectability and even whose shift from toxicity to edibility depends on preparation in the kitchen. The milkcaps Lactarius rufus and Lactarius trivialis and the false morel Gyromitra esculenta are three such mushrooms. The former two will burn your tongue if nibbled raw, and may bring on stomach-ache if not boiled prior to further cooking. The latter could kill you if it is

Bioenergy is the largest energy source in the Swedish energy system, where it consists mainly of domestic forest-based biomass in the form of residues and by-products. Today, there is a general discussion about the need for changes in national forest management policies and new European Union (EU) directives and regulations for forestry and bioenergy to better fulfil biodiversity and climate targe

This thesis examines the market access barriers faced by small-scale producers in Bolivia, with a focus on Chiquitania, Los Valles Cruceños, and Zongo. Drawing on 15 semi-structured interviews with producers, vendors, university staff, and institutional actors, it analyses how structural, institutional, and relational barriers shape not only producers’ ability to reach markets, but also their abil

Marine microorganisms have the potential to disperse widely with few obvious barriers to gene flow. However, among microalgae, several studies have demonstrated that species can be highly genetically structured with limited gene flow among populations, despite hydrographic connectivity. Ecological differentiation and local adaptation have been suggested as drivers of such population structure. Her

Ouagadougou is a city with three million inhabitants and an increasing demand for water of sufficient quality. New boreholes are drilled to match demand, but their protection from anthropogenic contamination is insufficient. To assess the quality of urban groundwater in Ouagadougou for the first time, a total of 32 borehole water samples were collected and assessed for bacteriological and physicoc

Habitat loss and nutrient enrichment are major drivers of plant species declines. However, local extinction risks vary widely and are shaped by life-history trait syndromes. Genomic life-history traits, which are simple, stable and widely available, offer a promising yet underexplored approach to improving extinction risk assessments and informing conservation efforts. Using a spatial comparison a

Increasing frequency and intensity of droughts threaten grassland ecosystems. Semi-natural grasslands vary in age from ancient to younger sites established on former arable land. While species richness and composition are known to affect drought resilience, little is known about how grassland age shapes drought responses through eco-evolutionary processes at the plant population level. We explored

Climate policies are challenged around the world, a development coinciding with the backlash of globalisation. The emergence of the modern welfare state, however, indicates that similar tensions may give rise to transformative change, if coinciding interests for change develop. This article explores the case of Sweden, critical due to its longstanding role as an environmental frontrunner, now expe

The salinization of freshwaters is a global threat to aquatic biodiversity. We quantified variation in chloride (Cl−) tolerance of 19 freshwater zooplankton species in four countries to answer three questions: (1) How much variation in Cl− tolerance is present among populations? (2) What factors predict intraspecific variation in Cl− tolerance? (3) Must we account for intraspecific variation to ac

International organizations within and outside the United Nations system provide platforms for multilateral cooperation and give impulses for national policymaking to promote the implementation of the Sustainable Development Goals (SDGs). They set agendas, coordinate efforts across regions and countries, offer technical assistance and expertise, compile data and monitor progress and raise awarenes

Galectins are a family of carbohydrate-recognising proteins involved in regulation of cell adhesion and cell signaling, leading to roles in e.g. cancer progression, fibrosis, and ulcerative colitis. Glycomimetic galectin inhibitors based on different molecular scaffolds are known and have demonstrated effects from cell experiments to the clinic. Presented here is the synthesis and evaluation of 3-

The bryophyte flora of the canyon Rövarekulan in Skåne, southern-most Sweden, has been thoroughly investigated as reported herein. Including historic records, a total of 200 taxa have been reported, whereof 181 were found in 2023–2024. The most spectacular finding was that of a small population of Didymodon luridus, until recently regarded as extinct in Sweden, growing in a crack in a south-facing

BACKGROUND: The strawberry tortrix, Acleris comariana (Lepidoptera: Tortricidae), is a destructive pest of strawberry in Denmark and southern Sweden. The efficacy of pheromone-based communication disruption of the species was examined in crop fields in southern Sweden. Due to the high cost of purchasing or synthesizing the pheromone (E)-11,13-tetradecadienal, lower quantities were applied per ha c

The currant bud moth, Euhyponomeutoides albithoracellus, the currant shoot borer, Lampronia capitella and the currant clearwing, Synanthedon tipuliformis, are destructive pests on currants in the Nordic countries, but detailed information about their relative abundance in commercial crop fields is lacking. We used pheromone-baited monitoring traps to analyse the presence and flight period of the t
