Effects of reduced diameter of bag cultures on content of essential fatty acids and cell density in a continuous algal production system
Jacobsen, Anita; Grahl-Nielsen, Otto; Magnesen, Thorolf (Peer reviewed; Journal article, 2011-02-16)Cell density and fatty acid (FA) content of Pavlova lutheri and Chaetoceros muelleri were analysed in a continuous algal production system (250-L bags) with reduced diameter. The cell density and FA content and composition ... -
Macromolecular sheets direct the morphology and orientation of plate-like biogenic guanine crystals
Wagner, Avital; Upcher, Alexander; Maria, Raquel; Magnesen, Thorolf; Zelinger, Einat; Raposo, Graca; Palmer, Benjamin (Journal article; Peer reviewed, 2023)Animals precisely control the morphology and assembly of guanine crystals to produce diverse optical phenomena in coloration and vision. However, little is known about how organisms regulate crystallization to produce ... -

Ermgassen, Philine S.E. Zu; Strand, Åsa; Bakker, Nienke; Blanco, Ainhoa; Bonačić, Kruno; Boudry, Pierre; Brundu, Gianni; Cameron, Tom C.; Connellan, Iarfhlaith; Da Costa, Fiz; Debney, Alison; Fabra, Monica; Frankic, Anamarija; Gamble, Celine; Gray, Mathew W.; Helmer, Luke; Holbrook, Zoë; Hugh-Jones, Tristan; Kamermans, Pauline; Magnesen, Thorolf; Nielsen, Pernille; Preston, Joanne; Ranger, Christopher J.; Saurel, Camille; Smyth, David; Stechele, Brecht; Theodorou, John A.; Colsoul, Bérenger (Journal article; Peer reviewed, 2023)The European flat oyster, Ostrea edulis, is a habitat-forming bivalve which was historically widespread throughout Europe. Following its decline due to overfishing, pollution, sedimentation, invasive species, and disease, ... -
Potential predation rates by the sea stars Asterias rubens and Marthasterias glacialis, on juvenile scallops, Pecten maximus, ready for sea ranching
Magnesen, Thorolf; Redmond, Kirsten Jayne (Peer reviewed; Journal article, 2012)The potential for predation by the sea stars Asterias rubens and Marthasterias glacialis on seed-size (41 ± 3 mm shell height) juvenile scallops (Pecten maximus), ready for seeding in sea ranching areas, was investigated ... -
Studentenes erfaring med veiledning. Semesteroppgaver for bedring av sluttkarakterer i MNF 115.
Magnesen, Thorolf (UPED-skrift nr. 1/2005, Working paper, 2005)MNF 115 “Natural science perspective on sustainable development” is an inter-faculty course for about 50 students. The course normally gets high student rating on general content and lectures, but low rating on student ... -
Temperature-associated selection linked to putative chromosomal inversions in king scallop (Pecten maximus)
Hollenbeck, Christopher M.; Portnoy, David S.; de la Serrana, Daniel Garcia; Magnesen, Thorolf; Matejusova, Iveta; Johnston, Ian A. (Journal article; Peer reviewed, 2022)The genomic landscape of divergence—the distribution of differences among populations or species across the genome—is increasingly characterized to understand the role that microevolutionary forces such as natural selection ... -
Ten priority questions for increasing the consistency and success in hatchery production of the European flat oyster for habitat restoration
Zu Ermgassen, Philine S.E.; Albentosa, Marina; Bakker, Nienke; Blanco, Ainhoa; Bonačić, Kruno; Carboni, Stefano; Brundu, Gianni; Colsoul, Bérenger; Araujo Piñeiro, Nicolás; Da Costa, Fiz; Dubbeldam, Marco; Fabra, Monica; Galley, Thomas; Gowland, Dennis; Jones, Nicholas; Hernández, Ángel; Hernandis, Sebastián; Laugen, Ane Timenes; Magnesen, Thorolf; Malham, Shelagh; Pogoda, Bernadette; Preston, Joanne; Sas, Hein; Saurel, Camille; Barja, Juan L.; Kamermans, Pauline (Journal article; Peer reviewed, 2023)The European flat oyster, Ostrea edulis, once formed extensive reef habitats throughout European seas and estuaries. These reefs are now largely functionally extinct, yet interest and support for their restoration is rapidly ...
