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 ... -
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 ... -
Polyploid Phylogenetics in Plants: Insights on non-model organisms in Fabaceae and Malvaceae
(2019-05-02)Genome duplication is a common phenomenon in angiosperms and advances in sequencing technologies and bioinformatics is now revealing its prevalence and significance. In a polyploidization event all genes in a genome are ... -
Microplastics in the aquatic environment: Insights into biological fate and effects in fish
(2019-03-26)According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. ... -
Assessing biodiversity: Beyond the taxonomic impediment
(2018-08-16)Precise and accurate quantification of biological diversity is crucial for many fields of biological research and for understanding ecosystem services, biological interactions, biogeography and designing management strategies ... -
Impacts of recreational boating in coastal seascapes and implications for management
(2018-04-12)Kosterhavet National Park, a marine protected area on the Swedish west coast, is a popular destination for tourists and attracts over half a million visitors annually. Many of the tourists arrive by boat, and the natural ... -
Big data insights into the distribution and evolution of tropical diversity
(2018-04-06)Tropical America (the Neotropics) and tropical Africa have comparable climate and share a geological history as parts of Gondwana. Nevertheless, the Neotropics today harbour roughly three times more flowering plant species ... -
Bivalves in the face of ocean acidification
(2018-03-22)Anthropogenic CO2 emissions are leading to a gradual decrease in ocean pH and changes in seawater carbonate chemistry, a process known as ocean acidification (OA). Such changes in oceanic environmental conditions will ... -
Investigation of [N-X-N]+ and [N-C-N]+ complexes in solution
(2017-11-02)Halogen bonding is a weak interaction. In this thesis the three center four electron halogen bond, [N−X−N]+, has been studied. The lighter halogens form highly unstable halonium ions that are reactive towards nucleophiles ... -
Plant Oxylipins and Lipid Transfer Proteins in Defense
(2017-10-20)Oxylipins, the oxygenated metabolites of polyunsaturated fatty acids (PUFAs), are found in many eukaryotic organisms. In plants, several enzymes can produce different types of oxylipins, and the chloroplast structural ... -
Sexual signalling and noise pollution - implications for courtship behaviour and reproductive success in two vocal species of marine gobies
(2017-08-24)Many marine animals use acoustic signals to mediate social interactions. Acoustic cues and signals are especially important in water because sound is unique as a sensory modality propagating with little attenuation over ... -
Risk assessment of chemical mixtures in the aquatic environment
(2017-04-26)The total chemical production within the European Union amounts to more than 300 million tonnes per year, of which 140 million tonnes are considered as hazardous to the environment. In order to ensure that these chemicals ... -
Thermal tolerance in teleost fish –importance of cardiac oxygen supply, ATP production and autonomic control
