Targeted risk assessment of mercury exposure of recreational fishers: Are nephrops fishers in Norway at risk?
(Journal article; Peer reviewed, 2021)Recreational fishers often consume their catch, which may expose them to environmental contaminants. However, targeted risk assessment for exceeding the tolerable weekly intake (TWI) of a specific contaminant is often ... -
Taurine Supplementation to Plant-Based Diets Improves Lipid Metabolism in Senegalese Sole
(Journal article; Peer reviewed, 2023)Taurine is a sulphur-containing amino acid with important physiological roles and a key compound for the synthesis of bile salts, which are essential for the emulsion and absorption of dietary lipids. This study aimed to ... -
Taxonomic overview of calcareous sponges (Porifera, Calcarea) in the Jan Mayen vent field at the Mohn Ridge
(Master thesis, 2013-12-17)The Porifera is a very old group of organisms that has been dated back to more than 500 million years. They are important to marine benthic communities by providing protection, contributing to nutrient recycling and working ... -
A taxonomic review of the Norwegian species of Raphitoma (Gastropoda: Conoidea: Raphitomidae)
(Peer reviewed; Journal article, 2016)The problematic conoidean genus Raphitoma s.l. in inshore Norwegian waters is revised based on fresh material from all along the coast of Norway. This largely shallow water group is represented by at least six species in ... -
Taxonomic review of the orders mysida and stygiomysida (Crustacea, Peracarida)
(Peer reviewed; Journal article, 2015-04-30)The order Mysida (2 families, 178 genera, 1132 species) contains species across a broad range of habitats, such as subterranean, fresh, brackish, coastal, and surface to deep-sea habitats. The Stygiomysida (2 families, 2 ... -
A taxonomic revision of the Caridean shrimp, Pasiphaea tarda (Krøyer, 1845)
(Master thesis, 2016-05-27)The taxonomic status of the Caridean shrimp, Pasiphaea tarda (Krøyer, 1845), has been a matter of debate throughout the years, and various authors have argued whether or not P. princeps and P. principalis should be synonymized ... -
The taxonomy and molecular phylogeny of Potentilla L. (Rosaceae) : An investigation of generic delimitation and reticulate evolution, using low-copy nuclear markers
(Doctoral thesis, 2021-01-15)The process of polyploidization (genome duplication) is a common mechanism in plant speciation. Autopolyploidy arises within one species, and allopolyploidy arises after hybridization. Ploidy levels in the genus Potentilla ... -
Taxonomy and morphology of Calciopappus curvus sp. nov. (Syracosphaeraceae, Prymnesiophyceae), a novel appendage-bearing coccolithophore
(Journal article; Peer reviewed, 2023)Based on scanning electron microscopy observations, a new species of the coccolithophore genus Calciopappus (Syracosphaeraceae, Prymnesiophyceae) is described from the surface waters off Bergen and from the lower photic ... -
Taxonomy of the order Mononegavirales: update 2019
(Journal article; Peer reviewed, 2019)In February 2019, following the annual taxon ratification vote, the order Mononegavirales was amended by the addition of four new subfamilies and 12 new genera and the creation of 28 novel species. This article presents ... -
Teleconnections between the northern North Atlantic and the Tropical Atlantic
(Master thesis, 2009-05-13)Paleoclimatic reconstructions of variations in rainfall and upwelling in the tropical Cariaco Basin, off Venezuela coast, suggest that meridional displacement of the Intertropical Convergence Zone (ITCZ) is linked ... -
The teleost fish PepT1-type peptide transporters and their relationships with neutral and charged substrates
(Journal article; Peer reviewed, 2023)In teleosts, two PepT1-type (Slc15a1) transporters, i.e., PepT1a and PepT1b, are expressed at the intestinal level. They translocate charged di/tripeptides with different efficiency, which depends on the position of the ... -
The teleost polymeric Ig receptor counterpart in ballan wrasse (Labrus bergylta) differs from pIgR in higher vertebrates
(Journal article; Peer reviewed, 2022)As mucosal barriers in fish are the main sites where pathogens are encountered, mucosal immunity is crucial to avoid infection in the aquatic environment. In teleost fish, immunoglobulins are present in gut, gill and skin ... -
A teleost structural analogue to the avian bursa of Fabricius
(Peer reviewed; Journal article, 2019-12-26)The bursa of Fabricius is a primary and secondary lymphoid organ considered exclusively present in birds, and studies of this structure have been vital to our current understanding of the adaptive immune system of vertebrates. ... -
Temperate infection in a virus–host system previously known for virulent dynamics
(Journal article; Peer reviewed, 2020)The blooming cosmopolitan coccolithophore Emiliania huxleyi and its viruses (EhVs) are a model for density-dependent virulent dynamics. EhVs commonly exhibit rapid viral reproduction and drive host death in high-density ... -
Temperature and size-dependency of lumpfish (Cyclopterus lumpus) oxygen requirement and tolerance
(Journal article; Peer reviewed, 2022)Lumpfish are currently produced and utilized as cleaner fish, to control sea lice infestation rates in salmon net pens, but information on environmental requirements is still limited. This study aimed to determine the zone ... -
Temperature dependent egg development and impact of light regimes on incubation of Ballan wrasse ( Labrus bergylta) egg

Temperature, precipitation and biotic interactions as determinants of tree seedling recruitment across the tree line ecotone
(Peer reviewed; Journal article, 2015-10)Seedling recruitment is a critical life history stage for trees, and successful recruitment is tightly linked to both abiotic factors and biotic interactions. In order to better understand how tree species’ distributions ... -
Temperature-associated selection linked to putative chromosomal inversions in king scallop (Pecten maximus)
(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 ... -
Temperature-dependent digestion handling time in juvenile cod and possible consequences for prey choice
(Peer reviewed; Journal article, 1999-05-18)The paper combines experimental work with modelling. The aim was to estimate the temperature-dependent digestion handling time, which is defined as the time taken to digest the whole prey or the whole stomach contents, and ...
