The aquatic ecotoxicity of manufactured silica nanomaterials and their interactions with organic pollutants
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
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!
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 ... -
Exciton coupling and energy transfer in perylene-based systems
(2022-01-07)Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and ... -
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 ... -
Cardiorespiratory function of euryhaline teleosts - Regulatory mechanisms, effects of warming and costs of osmoregulation
(2021-11-26)Teleost fishes have colonized almost every aquatic habitat on earth and exhibit adaptations that allow them to thrive in environments with very diverse physico-chemical properties. One fundamental environmental variable ... -
Effects of carbon dioxide and ozone on wheat crop yield and grain quality
(2021-10-05)Atmospheric concentrations of carbon dioxide (CO2) and ozone (O3) have steadily increased since the industrial revolution. CO2 and O3 directly affect plant physiology, CO2 being an essential substrate for photosynthesis, ... -
Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees
(2021-05-12)Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, ... -
Evolutionary genetics and consequences of inbreeding in sand lizards (Lacerta agilis)
(2021-05-04)Inbreeding is a well-known phenomenon in evolutionary and conservation biology. In the 19th century, Charles Darwin demonstrated the detrimental effects of inbreeding in plants, followed by over a century of extensive ... -
Interspecific Interactions between Native Brown Trout and Invasive Brook Trout: Insights into Behaviour and Morphology
(2021-04-28)The introduction of non-native species represents a global threat to ecosystems and biodiversity. In Europe, the introduction of the invasive brook trout (Salvelinus fontinalis) has led to species displacement and local ... -
Advancing Evolutionary Biology: Genomics, Bayesian Statistics, and Machine Learning
(2020-11-20)During the recent decades the field of evolutionary biology has entered the era of big data, which has transformed the field into an increasingly computational discipline. In this thesis I present novel computational method ... -
Taxonomy and Systematics of Thelephorales – Glimpses Into its Hidden Hyperdiversity
(2020-10-22)The order Thelephorales is a widespread group of many thousands of species of ecologically important, ectomycorrhizal fungi, of which only a fraction have been described to date. Most species are corticioid (skin-like) and ... -
Strong light-matter interaction and its consequences on molecular photophysics
(2020-09-15)Strong light-matter interaction offers the possibility to modify chemical and physical properties of molecules by modifying their photonic environment, resulting in the creation of hybrid light-matter states, known ... -
Reproductive traits in euryhaline gobies: insights into physiology, adaptations and biological invasions
(2020-03-24)Organisms are adapted to reproduce in their specific environment by a range of different traits. For many animals, reproduction is tied to specific conditions, that trigger or enable the reproductive events. This thesis ... -
A circular economy approach for sustainable feed in Swedish aquaculture: A nutrition and physiology perspective
(2019-10-25)One major challenge in aquaculture is the issue of fishmeal replacement as a protein source in aquafeeds. It is agreed that the rate of demand has now outpaced the rate of supply due to the rapid expansion of aquaculture. ... -
Calcium transport in the Pacific oyster, Crassostrea gigas - in a changing environment
(2019-09-23)Pacific oyster, Crassostrea gigas, is globally one of the most important farmed bivalve species. A prominent features of the C. gigas is the thick CaCO3 shell covering the body of the animal and protecting it from the ... -
Origin, evolution and biodiversity of the Neotropical herpetofauna: patterns and processes of the world’s richest and most threatened biota
(2019-09-16)The biological diversity of tropical America (the Neotropics) is astonishing. However, even among terrestrial vertebrates, most biogeographical patterns are not fully described nor understood, especially for many Neotropical ... -
Acclimation of boreal Norway spruce to climate change: Empirical and modelling approaches
(2019-09-04)The findings of this thesis have important implications for the projections of future carbon and water fluxes for the boreal region. The observed boreal longterm acclimation responses of respiration and stomatal regulation ... -
Heathlands – A Lost World?
(2019-05-03)Heathland is a familiar landscape type in southwest Sweden. It is open with few trees, and the vegetation is dominated by dwarf-shrubs growing on nutrient-poor soils. Dry heaths with Heather Calluna vulgaris and wet heaths ...
