Aquatic ecotoxicity of nanomaterials in fish in vitro models: Cytotoxicity and sublethal effect screening of pristine and transformed nanoparticles.
(2024-10-07)With the increased production and use of engineered nanoparticles (ENPs) came an increased risk of release into the aquatic environment. This has raised concerns about the unknown impact on the aquatic ecosystem. To improve ... -
Extensions of the Multispecies Coalescent in Bayesian Phylogenetics: A Study of the Southern African-centred Stoebe Clade (Gnaphalieae: Asteraceae)
(2024-09-30)The Tree of Life represents the complex relationships between all species, and recent advances in phylogenetic methods have dramatically expanded our ability to study these connections. However, there is still no universal ... -
Breaking the cage – Implementing photocages to address spatiotemporal challenges in chemical biology
(2024-04-16)Visualizing atoms and molecules in motion remains a formidable challenge within structural chemical biology. Significant advances in the generation of ultrashort and bright X-ray pulses have provided the technical framework ... -
Bridging the past to the present: investigating species boundaries with herbarium specimens and next-generation-sequencing. A case study of circumpolar Silene sect. Physolychnis
(2023-10-30)During the recent decades, genetic information enclosed in herbarium collections have been partly revealed, largely due to the fast-moving high-throughput sequencing technologies. However, the genetic outcome from herbarium ... -
Morphological and chemical leaf traits of tropical montane tree species and their responses to warming
(2023-10-26)Leaf morphological and chemical traits of tropical trees vary along climate gradients, but it is currently unclear how they will respond to a rapidly warming climate and how this will vary among species. Considering this, ... -
Novel Marine Ingredients for Aquaculture - Fish Nutrition, Physiology and Intestinal Health
(2023-10-24)Aquaculture is among the fastest growing food production sectors globally and supplies more fish to the growing human population than capture fisheries. One of the major challenges in salmonid aquaculture is to find ... -
Tomorrow is yesterday: early-life conditions shape ectotherm life histories
(2023-09-29)Life history theory seeks to explain the overwhelming diversity of resource allocation strategies in nature by exploring how evolutionary forces optimise survival and reproduction within an organism’s environment. Central ... -
Phylogenetic Relationships, Biogeography and Species Delimitation: A case study on southern African Silene (Caryophyllaceae)
(2023-09-20)The primary aim of this thesis was to explore the phylogenetic relationships and historical biogeography of African members of the plant genus Silene (Caryophyllaceae), with special focus on the eight native southern African ... -
Integrative physiology as a tool towards good animal welfare and sustainability in aquaculture: Focus on intestinal function and health
(2023-08-21)The human population is growing, and the world’s leaders are trying to provide humans with food resources and at the same time setting goals promoting sustainable food production. This means that we need to find new food ... -
Effects of contaminant mixtures on marine zooplankton diversity and function
(2023-05-02)Chemicals have important roles in our society and can be used as ingredients in personal care products, pesticides, pharmaceuticals, as well as be components of fuels used in cars or ships. More than 350 000 chemicals and ... -
Characterization of ion transport proteins involved in chloroplast function from land plants and algae
(2022-10-21)Evolved around 2.4 billion years ago and even earlier, according to the new geochemical evidence, oxygenic photosynthesis is the crucial turning point in the history of our planet. Used by cyanobacteria, algae, and ... -
Thermal plasticity and limitations in tropical trees
(2022-09-12)Tropical forests are the most carbon dense and biodiverse terrestrial biome on earth. In a time of global warming and biodiversity crisis, their preservation must be of high priority. At the same time, they likely operate ... -
Wood-living beetle diversity and Swedish forest management
(2022-08-29)Humans have impacted Fennoscandian forests for thousands of years, through grazing, burning, and since the industrial revolution increasingly through efficient industrial forestry. These impacts have changed the composition ... -
The aquatic ecotoxicity of manufactured silica nanomaterials and their interactions with organic pollutants
(2022-05-20)Manufactured silica nanomaterials are one of the nanomaterials consumed in the highest volumes (more than 4 000 000 tons/year/globally) and are used in a wide range of products and industries such as food, cosmetics, ... -
A landscape of values - a study of non-epistemic values in Swedish upper secondary science education
(2022-04-26)This thesis sets out to investigate the role of non-epistemic values in science education from three actors’ perspectives – the science student, the science teacher, and the science teacher educator. More specifically, the ... -
Mutagenesis in wheat: An approach to make saline green!
(2022-04-01)The raising salinity in the soils around the world have been widely studied during the last decades due to the massive loss in agricultural land. Today, nearly 8% of the world’s arable land can no longer be used for crop ... -
Parasite host interaction between the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) – the impact from glochidia larvae on the host
(2022-02-17)Parasites can modulate the physiology and behavior of the hosts to enhance their chances to complete their life cycle. The numerous freshwater bivalves of the order Unionoida all have a parasitic larval stage, also known ... -
Effects of mixtures of endocrine disrupting chemicals – Thyroid disruption and behavioural effects in fish models
(2022-01-07)Wildlife and humans are continuously exposed to thousands of man-made compounds, including chemicals that are able to act as endocrine disruptors (EDCs). These pollutants are able to affect vital processes including brain ... -
