Chironomids, temperature and numerical models: a reply to Seppälä
(Peer reviewed; Journal article, 2001)We reply to comments by Seppälä (2001) concerning the suitability of the surface-water temperature measurements and mean July air temperature estimates used by Olanderet al. (1999) to derive quantitative chironomid-temperature ... -
Chitin synthases are critical for reproduction, molting, and digestion in the salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2021-01-13)Chitin synthase (CHS) is a large transmembrane enzyme that polymerizes Uridine diphosphate N-acetylglucosamine into chitin. The genomes of insects often encode two chitin synthases, CHS1 and CHS2. Their functional roles ... -
Chitin synthesis in the salmon louse Lepeophtheirus salmonis
(Doctoral thesis, 2021-08-13)The salmon louse Lepeophtheirus salmonis is a parasitic copepod that lives and feeds on Atlantic salmon (Salmo salmar). At present, this parasite is the number one threat to the Norwegian aquaculture. The density of salmons ... -
Chitinase digestion for the analysis of microplastics in chitinaceous organisms using the terrestrial isopod Oniscus asellus L. as a model organism
(Journal article; Peer reviewed, 2021)Chitinaceous organisms have been found to ingest microplastic; however, a standardised, validated, and time- and cost-efficient method for dissolving these organisms without affecting microplastic particles is still required. ... -
Cholesterol-containing lipid nanodiscs promote an α-synuclein binding mode that accelerates oligomerization
(Journal article; Peer reviewed, 2021)Dysregulation of the biosynthesis of cholesterol and other lipids has been implicated in many neurological diseases, including Parkinson's disease. Misfolding of α-synuclein (α-Syn), the main actor in Parkinson's disease, ... -
Chromosome aberrations in pressureinduced triploid Atlantic salmon
(Journal article; Peer reviewed, 2020)Background Triploid organisms have three sets of chromosomes. In Atlantic salmon, hydrostatic pressure treatment of newly fertilized eggs has been extensively used to produce triploids which are functionally sterile due ... -
A chromosome-level assembly of the Atlantic herring genome-detection of a supergene and other signals of selection
(Peer reviewed; Journal article, 2019)The Atlantic herring is a model species for exploring the genetic basis for ecological adaptation, due to its huge population size and extremely low genetic differentiation at selectively neutral loci. However, such studies ... -
Circum-Arctic distribution of chemical anti-herbivore compounds suggests biome-wide trade-off in defence strategies in Arctic shrubs
(Journal article; Peer reviewed, 2022)Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top–down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, ... -
The cladorhizid fauna (Porifera, Poecilosclerida) of the Caribbean and adjacent waters
(Peer reviewed; Journal article, 2016-10-19)The carnivorous sponge family Cladorhizidae has been subject to several recent studies, yet the cladorhizid fauna of the Caribbean and adjacent areas remain comparatively poorly known. In this article we provide a description ... -
Cladorhizid sponges from hydrothermal vents and cold seeps in the NE Atlantic Ocean
(Master thesis, 2009-09-30)Sponges are known to frequently contain a great number of symbiotic organisms. Symbiosis is also a characteristic trait of vent and seep animals worldwide. Sponges in the deep sea family Cladorhizidae, otherwise also known ... -
Class I Phosphoinositide 3-Kinase PIK3CA/p110α and PIK3CB/p110β Isoforms in Endometrial Cancer
(Peer reviewed; Journal article, 2018-12-07)The phosphoinositide 3-kinase (PI3K) signalling pathway is highly dysregulated in cancer, leading to elevated PI3K signalling and altered cellular processes that contribute to tumour development. The pathway is normally ... -
Classification and phylogeny for the annotation of novel eukaryotic GNAT acetyltransferases
(Journal article; Peer reviewed, 2020)The enzymes of the GCN5-related N-acetyltransferase (GNAT) superfamily count more than 870 000 members through all kingdoms of life and share the same structural fold. GNAT enzymes transfer an acyl moiety from acyl coenzyme ... -
“A cleaner break”: Genetic divergence between geographic groups and sympatric phenotypes revealed in ballan wrasse (Labrus bergylta)
(Journal article; Peer reviewed, 2020)Capture and long‐distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in ... -
Cleaner Fish Do Not Impact the Pigmentation of Salmon Lice (Lepeophtheirus salmonis) in Commercial Aquaculture Cages
(Journal article; Peer reviewed, 2023-09-10)Salmon lice are one of the biggest challenges to sustainable salmonid aquaculture. The species display high evolutionary potential, which is evident by its development of resistance to numerous chemical compounds used for ... -
Cleaner fish growth, welfare and survival in Atlantic salmon sea cages during an autumn-winter production
(Journal article; Peer reviewed, 2020)Cleaner fish used as a biological control agent against salmon lice is rapidly increasing in Atlantic salmon aquaculture. However, concerns have been raised about the welfare and mortality of cleaner fish in salmon cage ... -
Climate and biotic interactions – drivers of plant community structure and ecosystem functioning in alpine grasslands
(Doctoral thesis, 2019-10-21)The governing of biodiversity by climate is profound. Climate as reflected through the major global temperature and precipitation axes determines the distribution of species according to their climatic tolerance, or niche. ... -
Climate change and the effect of darker coastal water on NCW euphotic zone properties - A theoretical study
(Master thesis, 2016-11-21)The Norwegian Coastal Water (NCW) derives from an extensive outflow of freshwater from the Baltic Sea and river runoff from the Norwegian coast, making the water less saline than the North Atlantic Water (NAW). Freshwater ... -
Climate change in fish: effects of respiratory constraints on optimal life history and behaviour
(Peer reviewed; Journal article, 2015)The difference between maximum metabolic rate and standard metabolic rate is referred to as aerobic scope, and because it constrains performance it is suggested to constitute a key limiting process prescribing how fish may ... -
Climate change winner in the deep sea? Predicting the impacts of climate change on the distribution of the glass sponge Vazella pourtalesii
(Journal article; Peer reviewed, 2021)Shallow-water sponges are often cited as being ‘climate change winners’ due to their resiliency against climate change effects compared to other benthic taxa. However, little is known of the impacts of climate change on ... -
