Dispersal of Microalgae- the role of Biological and Physical Barriers
(2015-09-04)Microalgae are only a few micrometres to a millimetre in size, yet they constitute the base for aquatic food webs and are extremely important drivers in elemental cycling. Long it has been assumed that small organisms (<1 ... -
Early Life History of the cold-water coral Lophelia pertusa - with implications for dispersal
(2016-03-18)For sessile marine invertebrates the pelagic larval stage is the only means for dispersal, and thus govern population connectivity and maintenance of genetic diversity. It is also a kind of life insurance, i.e. it reduces ... -
Estimating the Air-Water Gas Transfer Velocity during Low Wind Conditions
(2016-04-06)The abundances of atmospheric carbon dioxide, CO2, and methane, CH4, are increasing. These increases affect e.g., the global carbon cycle and the climate both regionally and globally. To better understand the present and ... -
Genetic structuring in natural populations - the influence of life history strategies and asymmetric migration
(2016-09-09)In this thesis I investigate aspects of genetic differentiation and factors influencing the structure of populations. This is done with a special focus on life histories and dispersal strategies common in the marine ... -
Restoration and management of eelgrass (Zostera marina) on the west coast of Sweden
(2016-11-11)Since the 1980s over 60% of eelgrass (Zostera marina) habitats have been lost from the Swedish NW coast, resulting in significant losses of the valuable ecosystem services provided by these habitats. The eelgrass loss has ... -
Biodiversity and Ecosystem Functioning - What Diversity? Which Functioning?
(2017-05-12)We share our planet with an estimated 8.7 million eukaryotic species and an uncountable number of bacteria and archaea. But that amazing diversity is under threat from overexploitation, habitat destruction and climate ... -
Ocean circulation in the Amundsen Sea, West Antarctica
(2017-05-30)The increase of mass loss from the Antarctic Ice Sheet is a significant contribution to global sea level rise. The most rapid changes are occurring in the Amundsen Sea area, where the thinning of the floating glaciers is ... -
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 ... -
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 ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
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 ... -
Genetic Identification of Corkwing Wrasse Cleaner Fish Escaping from Norwegian Aquaculture
(University of Gothenburg / Göteborgs universitet, 2021)The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. Here, ... -

Havsis längs svenska västkusten
(University of Gothenburg / Göteborgs universitet, 2021)Det är något alldeles speciellt med is, som många som åker skridskor på våra vinterisar vet. Årets möjlighet att få åka på havet längs den svenska västkusten väckte både sprudlande glädje och osäkerhet inför havsisen.
