Evolutionary and Ecological Effects of Metal Pollution on Coastal Diatoms
(2022-10-21)Oceans are changing rapidly in response to human activities, such as toxic pollution, eutrophication, and climate change. Diatoms are major primary producers in the oceans with short generation times, flexible reproductive ... -
Modelling the Evolution of Species’ Ranges
(2022-09-16)The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental ... -
Microbial degradation of wooden foundation piles in urban context – causes and concerns
(2022-05-18)Modern infrastructural projects can endanger historical piled foundations supporting cultural heritage buildings, as groundwork can affect the subsurface environment by lowering the local groundwater level and increasing ... -
Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export
(2022-05-12)The sea ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, ... -
Ocean mixing and polynyas at Maud Rise, Weddell Sea
(2022-04-22)The Weddell Sea Polynya is an intermittent, ice free area in the marginal ice zone with an extent of up to 350 000 km². It was first observed by satellites in the winter seasons of 1974-1976. In 2016 and 2017, an open-ocean ... -
Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture
(2022-04-21)Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control ... -
Nutrient dynamics in coastal and shelf oceans - sediments as a regulator of eutrophication feedbacks
(2022-01-10)Coastal and shelf systems are under increasing pressure from human activities. Many coastal systems currently suffer from excessive algae growth following increased nutrient input from land, a process called eutrophication. ... -
New Perspectives in Multi-trophic Aquaculture
(2021-05-26)Aquaculture, the farming of marine and aquatic organisms, is currently the fastest growing food production sector globally. As capture fisheries have stagnated and the fishing down of marine food webs has been seen to be ... -
Habitat-Forming Seaweeds in a Changing Climate
(2021-05-19)Climate change is an umbrella term encompassing some of the largest and most potent selective pressures currently acting on ecosystems. It can have diverse effects on marine systems; the most powerful of which are changes ... -
Reproductive isolation at contact zones
(2021-01-18)Speciation is among the most important evolutionary processes that contribute to biodiversity. It involves the formation of new species that have become reproductively isolated through a process that is not linear and ... -
Practical application of machine learning for analyses of biological matrices and environmental phenomena.
(2020-09-11)This thesis presents research aimed at forwarding an understanding of machine learning methods as a method of studying complex matrices and environmental phenomena. A number of machine learning methods in the form of linear ... -
Sources and fate of plastic particles in northern European coastal waters
(2019-12-11)Plastics are integral parts of our lives and have allowed for important technological leaps within society. However, an unwanted consequence of our current consumption of plas-tics is marine plastic pollution and in order ... -
Sustainable Kelp Aquaculture in Sweden
(2019-10-29)Seaweed aquaculture is gaining more interest worldwide, including Europe. However, despite its long coast seaweed farming is still very minor in Sweden. The overarching aim of this thesis is to develop sustainable cultivation ... -
Carbon cycling in Baltic Sea sediments – In situ investigations with benthic landers
(2018-05-25)Coastal seas, estuaries and continental shelves are the connection between land and the open ocean, and due to high productivity and strong influence from land a majority of the marine organic carbon (OC) cycling and ... -
Carbon and nitrogen fluxes associated to marine and estuarine phytoplankton
(2018-05-14)Globally, mainly nitrogen or phosphorus is limiting the primary production. New nitrogen can enter estuarine ecosystems as nitrate from upwelling events, from river runoff, atmospheric deposition, or by nitrogen fixation. ... -
Seagrass Wasting Disease Impact of abiotic factors and chemical defense
(2017-12-04)Eelgrass, Zostera marina, is the dominant seagrass species in the northern hemisphere, and forms large meadows that provide several important ecosystem services. In the 1930s about 90% of the Z. marina populations in the ... -
From Sea to Society - Climate Change, Microbial Community Interactions and Assessing Climate Risk on Society
(2017-11-11)Unicellular organisms, microalgae and bacteria, less than one millimeter in size make the world go round. Phytoplankton and cyanobacteria, for example, plays an inevitable role contributing 50-85% to the world’s oxygen ... -
Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors
(2017-11-06)Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food ... -
Evaluation of suitable nursery areas for penaeid shrimps in shallow water systems in southern Mozambique
(2017-10-09)Tropical shallow water habitats such as estuaries, mangrove forests and seagrass beds are important nursery areas for juveniles of many commercially important species including penaeid shrimp. Penaeids are one of the most ...
