Evolution of growth in Gulf of St Lawrence cod?
(Journal article; Peer reviewed, 2008-06-22)Fishing is often size selective such that the likelihood of capture increases with body size. It has therefore been postulated that fishing could favour evolution of slower growth because smaller size would reduce exposure ... -
Evolution of reproduction periods in seasonal environments
(Peer reviewed; Journal article, 2020)Many species are subject to seasonal cycles in resource availability, affecting the timing of their reproduction. Using a stage-structured consumer-resource model in which juvenile development and maturation are resource ... -
Evolution of the immune system influences speciation rates in teleost fishes
(Journal article; Peer reviewed, 2016)Teleost fishes constitute the most species-rich vertebrate clade and exhibit extensive genetic and phenotypic variation, including diverse immune defense strategies. The genomic basis of a particularly aberrant strategy ... -
Evolutionary drivers of kype size in atlantic salmon (salmo salar): domestication, age and genetics
(Journal article; Peer reviewed, 2019)The diversity of reproduction and associated mating patterns in Atlantic salmon (Salmo salar) has long captivated evolutionary biologists. Salmo salar exhibit strategies involving migration, bold mating behaviours and ... -
Evolutionary effects of fishing gear on foraging behavior and life-history traits
(Journal article; Peer reviewed, 2018)Fishing gears are designed to exploit the natural behaviors of fish, and the concern that fishing may cause evolution of behavioral traits has been receiving increasing attention. The first intuitive expectation is that ... -
An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L.
(Peer reviewed; Journal article, 2023)Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ... -
Evolutionary history and seascape genomics of Harbour porpoises (Phocoena phocoena) across environmental gradients in the North Atlantic and adjacent waters
(Peer reviewed; Journal article, 2023)The Harbour porpoise (Phocoena phocoena) is a highly mobile cetacean species primarily occurring in coastal and shelf waters across the Northern hemisphere. It inhabits heterogeneous seascapes broadly varying in salinity ... -
Evolutionary predictions for a parasite metapopulation: Modelling salmon louse resistance to pest controls in aquaculture
(Peer reviewed; Journal article, 2023)Pests often evolve resistance to pest controls used in agriculture and aquaculture. The rate of pest adaptation is influenced by the type of control, the selective pressure it imposes, and the gene flow between farms. By ... -
Evolutionary principles and their practical application
(Journal article; Peer reviewed, 2011-02-17)Evolutionary principles are now routinely incorporated into medicine and agriculture. Examples include the design of treatments that slow the evolution of resistance by weeds, pests, and pathogens, and the design of breeding ... -
Exitomelita sigynae gen. et sp. nov.: a new amphipod from the Arctic Loki Castle vent field with potential gill ectosymbionts
(Journal article; Peer reviewed, 2011-11-02)The newly discovered deep-sea hydrothermal vent field ‘‘Loki’s Castle’’ at 2,350 m depth at 70 N on the Knipovich Ridge north of the island Jan Mayen is the only known black smoker field from the Arctic Ridge system. This ... -
The exorhodopsin and melanopsin systems in the pineal complex and brain at early developmental stages of Atlantic halibut (Hippoglossus hippoglossus)
(Peer reviewed; Journal article, 2014)The complexity of the nonvisual photoreception systems in teleosts has just started to be appreciated, with colocalization of multiple photoreceptor types with unresolved functions. Here we describe an intricate expression ... -
An Expanded Gene Catalog of Mouse Gut Metagenomes
(Peer reviewed; Journal article, 2021)High-quality and comprehensive reference gene catalogs are essential for metagenomic research. The rather low diversity of samples used to construct existing catalogs of the mouse gut metagenome limits the numbers of ... -
Expected Climate Change in the High Arctic—Good or Bad for Arctic Charr?
(Peer reviewed; Journal article, 2023)Lakes in the High Arctic are characterized by their low water temperature, long-term ice cover, low levels of nutrients, and low biodiversity. These conditions mean that minor climatic changes may be of great importance ... -
Experimental evidence of threat-sensitive collective avoidance responses in a large wild-caught herring school
(Peer reviewed; Journal article, 2014)Aggregation is commonly thought to improve animals’ security. Within aquatic ecosystems, group-living prey can learn about immediate threats using cues perceived directly from predators, or from collective behaviours, for ... -
Experimental Evidence of Threat-Sensitive Collective Avoidance Responses in a Large Wild-Caught Herring School
(Journal article; Peer reviewed, 2014-01-29)Aggregation is commonly thought to improve animals' security. Within aquatic ecosystems, group-living prey can learn about immediate threats using cues perceived directly from predators, or from collective behaviours, for ... -
Experimental infection of turbot Scophthalmus maximus and halibut Hippoglossus hippoglossus yolk sac larvae with Aeromonas salmonicida subsp. salmonicida
(Journal article; Peer reviewed, 1997-04-24)The susceptibility of early life stages of turbot Scophthalmus maximus and halibut Hippoglossus hippoglossus to Aeromonas salmonicida subsp. salmonicida was studied in challenge experiments. Eggs of both fish species (and ... -
Experimental Parameterisation of Principal Physics in Buoyancy Variations of Marine Teleost Eggs
(Journal article; Peer reviewed, 2014-08-14)It is generally accepted that the high buoyancy of pelagic marine eggs is due to substantial influx of water across the cell membrane just before ovulation. Here we further develop the theoretical basis by applying laboratory ... -
Experimental transmission of piscine orthoreovirus-1 (PRV-1) in different life stages of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
(Peer reviewed; Journal article, 2023)Piscine orthoreovirus -1 (PRV-1) causes the disease heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon, and the virus has been detected in wild anadromous Atlantic salmon and brown trout. However, the ... -
Expert-driven methodology to assess and predict the effects of drivers of change on vulnerabilities in a food supply chain: Aquaculture of Atlantic salmon in Norway as a showcase
(Peer reviewed; Journal article, 2020)In the last decades, food produced by aquaculture has seen an impressive increase worldwide but maintaining high quality and safety is increasingly becoming a concern. It is apparent that changes in- and outside the ...
