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. ... -
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 ... -
Adaptation to the Baltic Sea – the case of isopod genus Idotea
(2013-05-16)The three marine isopods of the genus Idotea: I. balthica, I. chelipes and I. granulosa have an important functional role as meso-grazers in the Baltic food web. These meso-grazers are key species in the Fucus belt and in ... -
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 ... -
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, ... -
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 ... -
Assessment of dietary patterns and prey consumption of marine mammals: Grey seals (Halichoerus grypus) in the Baltic Sea
(2012-02-09)The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. In the ... -
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 ... -
Biochemical studies of the essential Clp protease in cyanobacteria and its associated adaptor proteins
(2014-10-03)Proteins are an essential part of all organisms and are involved in many cellular processes. To regulate the function of proteins and facilitate their removal when damaged or otherwise compromised, sophisticated control ... -
Biologisk mångfald i läroböcker i biologi
(2014-10-17)The aim of this thesis is to analyse offered meaning, that is, what and how subject content is communicated to the recipients. In this case the subject content is biological diversity and the communicative artefacts are ... -
Biomarkers for assessing benthic pollution impacts in a subtropical estuary, Mozambique
(2015-05-11)This thesis focuses on the marine environment in a subtropical estuary and particularly on exploring a suite of easy-to-use, cost effective and environmentally valid biological response tools (biomarkers). The main driving ... -
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 ... -
Blue Oceans with Blue Mussels - Management and planning of mussel farming in coastal ecosystems
(2014-11-03)Eutrophication is one of the largest and most serious global threats to the marine environment. The effect of eutrophication has become increasingly clear during recent time, and major economic and political efforts are ... -
Broadening the perspective on seafood production: Life cycle thinking and fisheries management
(2014-03-28)Decisions made by fisheries managers strongly influence the overall resource use and environmental impacts associated with the seafood product from capture fisheries. These findings come from Life Cycle Assessments (LCA), ... -
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 ... -
Carbon and nutrient cycling in Afromontane tropical forests at different successional stages
(2016-11-18)To date, studies of the carbon and nutrient cycling in tropical montane forests have been restricted to a few, mostly neotropical, sites. This thesis investigated the carbon and nutrient cycling of early (ES) and late (LS) ... -
Carbon Dioxide and Water Vapour Exchange within a Norway Spruce Canopy
(2012-05-04)Terrestrial ecosystems can act both as sinks and sources in the global carbon cycle. Forests are an important part of this system and a good understanding of their carbon balance is essential for assessments of the future ... -
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 ... -
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 ... -
Chemical mixtures and interactions with detoxification mechanisms and biomarker responses in fish
(2015-01-09)Several classes of anthropogenic chemicals are present as mixtures in the aquatic environment. However, information of how wildlife species, including fish, are affected by exposures to chemical mixtures is limited. Chemicals ...
