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 ... -
Insights into Marine Fish Physiology in a Changing World
(2016-01-15)Ocean acidification and global warming are largely caused by increased levels of atmospheric CO2, and marine fish are exposed to both these stressors simultaneously. Although the effects of temperature on fish have been ... -
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 ... -
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 ... -
Intestinal Mucosal Immunology of Salmonids Response to Stress and Infection and Crosstalk with the Physical Barrier
(2013-05-15)The effect of environmental factors and pathogens on the intestinal epithelium of fish has received increased attention in recent years. Studies focusing on effects of stress, nutrient uptake as well as vegetable ingredients ... -
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 ... -
Ion Transport in Chloroplasts with Role in Regulation of Photosynthesis
(2015-09-14)Photosynthesis is the primary energy source of almost all ecosystems on Earth. Oxygenic photosynthesis has appeared approximately 2.4 billion years ago and has since then gradually evolved into the complex process that ... -
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 ... -
Leptin endocrinology and energy homeostasis in salmonids
(2015-12-28)In salmonids, the physiological role of leptin is not completely elucidated. Nonetheless, the anorexigenic effect of leptin indicates a role in their energy homeostasis. This thesis focuses on advancing the understanding ... -
Light-regulated Development in Arabidopsis
(2014-09-30)Many external and internal factors affect multiple developmental processes in plants. Light is one of the essential factors that regulates various aspects of plant growth and development throughout their life cycle. Through ... -
Mate choice and its evolutionary consequences in intertidal snails (Littorina spp.)
(2013-05-06)The ability to recognise potential mates and choose the best possible partner for reproduction is of fundamental importance for most animal species. This thesis presents studies of mate choice in marine snails of the genus ... -
Microbial Biofilms in the Bioinformatics Era
(2016-05-30)Adverse effects of anthropogenic impact on the environment have become conspicuous in the past century and among others include the gradual increase in the global CO2 levels, the contamination of air, soil and water by ... -
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. ... -
Migration in anadromous brown trout
(2016-02-16)This thesis investigates the anadromous migration of brown trout (Salmo trutta) with the overall aim to improve stock management within the region. Several field studies were conducted in different streams and coastal areas ... -
Molecular mechanisms optimizing photosynthesis during high light stress in plants
(2014-04-04)ABSTRACT: Oxygenic photosynthesis is the process by which plants, algae and cyanobacteria usesolar energy to convert water and carbon dioxide into molecular oxygen and carbohydrates.Photosynthesis sustains life on Earth ... -
Molecular Systematics of Limnodrilus (Annelida, Clitellata)
(2017-02-27)The freshwater Limnodrilus worms (Clitellata: Naididae: Tubificinae) are segmented hermaphroditic annelids, bearing a unique clitellum (“girdle”) during sexual maturity. Some abundant and common taxa of Limnodrilus are ... -
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, ... -
Mutagenesis and transcriptome mapping in oat and characterization of high β-glucan lines
(2013-04-25)Oat (Avena sativa) is a hexaploid crop that is cultivated in Europe, North America, Russia, Australia and northern China. During recent years, oat has seen increased interest due to its potential as a functional food crop. ... -
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 ... -
Next-generation Molecular Systematics and Evolution: insights into Medicago
(2015-04-29)Evolutionary relationships among species have in recent years been inferred using DNA sequences from specific genes and represented by tree diagrams (phylogenies). However, the signal contained in different genes can produce ...
