Dispersal similarly shapes both population genetics and community patterns in the marine realm
(Journal article; Peer reviewed, 2016-06-27)Dispersal plays a key role to connect populations and, if limited, is one of the main processes to maintain and generate regional biodiversity. According to neutral theories of molecular evolution and biodiversity, dispersal ... -
Distribution and genetic diversity of Anisakis spp. in cetaceans from the Northeast Atlantic Ocean and the Mediterranean Sea
(Peer reviewed; Journal article, 2022)Parasite biodiversity in cetaceans represents a neglected component of the marine ecosystem. This study aimed to investigate the distribution and genetic diversity of anisakid nematodes of the genus Anisakis sampled in ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Peer reviewed; Journal article, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -
Dnd knockout ablates germ cells and demonstrates germ cell independent sex differentiation in Atlantic salmon
(Journal article; Peer reviewed, 2016-02-18)Introgression of farmed salmon escapees into wild stocks is a major threat to the genetic integrity of wild populations. Using germ cell-free fish in aquaculture may mitigate this problem. Our study investigated whether ... -
Domestication leads to increased predation susceptibilit
(Journal article; Peer reviewed, 2020)Domestication involves adapting animals to the human-controlled environment. Genetic changes occurring during the domestication process may manifest themselves in phenotypes that render domesticated animals maladaptive for ... -
Dynamical controls on the longevity of a non-linear vortex : The case of the Lofoten Basin Eddy
(Journal article; Peer reviewed, 2019)The Lofoten Basin is the largest oceanic reservoir of heat in the Nordic Seas, and the site of important heat fluxes to the atmosphere. An intense permanent anticyclone in the basin impacts the regional hydrography, ... -
The effectiveness of hyposaline treatments against host-attached salmon lice
(Peer reviewed; Journal article, 2019)Understanding how salinity affects marine parasites is vital to understanding their ecology and treatment, particularly for host-parasite systems that traverse marine and freshwater realms such as the globally important ... -
Efficient coralline algal psbA mini barcoding and High Resolution Melt HRM) analysis using a simple custom DNA preparation
(Journal article; Peer reviewed, 2019)Coralline algae form extensive maerl and rhodolith habitats that support a rich biodiversity. Calcium carbonate harvesting as well as trawling activities threatens this ecosystem. Eleven species were recorded so far as ... -

Empirical support for sequential imprinting during downstream migration in Atlantic salmon (Salmo salar) smolts
(Peer reviewed; Journal article, 2022)The precise homing of Atlantic salmon to their natal river and spawning grounds is the foundation for locally adapted genetically differentiated populations across rivers or across river sections. A sequential imprinting ... -
First thorough assessment of de novo oocyte recruitment in a teleost serial spawner, the Northeast Atlantic mackerel (Scomber scombrus) case
(Peer reviewed; Journal article, 2021)The understanding of teleost fecundity type (determinate or indeterminate) is essential when deciding which egg production method should be applied to ultimately estimate spawning stock biomass. The fecundity type is, ... -
Genomic disturbance of vitellogenin 2 (vtg2) leads to vitellin membrane deficiencies and significant mortalities at early stages of embryonic development in zebrafish (Danio rerio)
(Peer reviewed; Journal article, 2023)The specific functions and essentiality of type II vitellogenin (Vtg2) in early zebrafish development were investigated in this study. A vtg2-mutant zebrafish line was produced and effects of genomic disturbance were ... -
Grazers extend blue carbon transfer by slowing sinking speeds of kelp detritus
(Peer reviewed; Journal article, 2018)Marine plant communities such as kelp forests produce significant amounts of detritus, most of which is exported to areas where it can constitute an important trophic subsidy or potentially be sequestered in marine sediments. ... -
Green gravel: a novel restoration tool to combat kelp forests decline.
(Peer reviewed; Journal article, 2020)Kelp forests are in decline globally and large-scale intervention could be required to halt the loss of these valuable ecosystems. To date kelp forest restoration has had limited success and been expensive and unable to ... -
Hydropower-induced selection of behavioural traits in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Renewable energy projects such as hydropower facilities contribute towards meeting the world`s growing energy demands and urgent need for mitigating climate change. However, such infrastructure has the potential to ... -
In situ recordings of large gelatinous spheres from NE Atlantic, and the first genetic confirmation of egg mass of Illex coindetii (Vérany, 1839) (Cephalopoda, Mollusca)
(Peer reviewed; Journal article, 2021)In total, 90 gelatinous spheres, averaging one meter in diameter, have been recorded from ~ 1985 to 2019 from the NE Atlantic Ocean, including the Mediterranean Sea, using citizen science. More than 50% had a dark streak ... -
Indel locations are determined by template polarity in highly efficient in vivo CRISPR/Cas9- mediated HDR in Atlantic salmon
(Peer reviewed; Journal article, 2020)Precise gene editing such as CRISPR/Cas9-mediated homology directed repair (HDR) can increase our understanding of gene function and improve traits of importance for aquaculture. This fine-tuned technology has not been ... -
Individual and population-level responses to ocean acidification
(Journal article; Peer reviewed, 2016-01-29)Ocean acidification is predicted to have detrimental effects on many marine organisms and ecological processes. Despite growing evidence for direct impacts on specific species, few studies have simultaneously considered ... -
Joint temporal trends in river thermal and hydrological conditions can threaten the downstream migration of the critically endangered European eel
