Genomic Insights into Methanotrophy: The Complete Genome Sequence of Methylococcus capsulatus (Bath)
(Peer reviewed; Journal article, 2004-09-21)Methanotrophs are ubiquitous bacteria that can use the greenhouse gas methane as a sole carbon and energy source for growth, thus playing major roles in global carbon cycles, and in particular, substantially reducing ... -
Genomic Resources for Sea Lice: Analysis of ESTs and Mitochondrial Genomes
(Peer reviewed; Journal article, 2011-07-12)Sea lice are common parasites of both farmed and wild salmon. Salmon farming constitutes an important economic market in North America, South America, and Northern Europe. Infections with sea lice can result in significant ... -
Genomic Signatures of Local Adaptation under High Gene Flow in Lumpfish—Implications for Broodstock Provenance Sourcing and Larval Production
(Journal article; Peer reviewed, 2023-09-26)Aquaculture of the lumpfish (Cyclopterus lumpus L.) has become a large, lucrative industry owing to the escalating demand for “cleaner fish” to minimise sea lice infestations in Atlantic salmon mariculture farms. We used ... -
Genotyping of Tenacibaculum maritimum isolates from farmed Atlantic salmon in Western Canada
(Peer reviewed; Journal article, 2018-01)Mouthrot infections (bacterial stomatitis) have a significant impact on the Atlantic salmon aquaculture industry in Western Canada due to economic losses and fish welfare. Bacteria isolated from lesions in the field have ... -
Genotyping tool for salmonid gill pox virus (SGPV) obtained from farmed and wild Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2023)Poxviruses are common viruses found in vertebrate species. In 2006, the first poxvirus associated with salmon, salmonid gill poxvirus (SGPV), was identified during an outbreak of gill disease at a smolt production site in ... -
Geochemical transition zone powering microbial growth in subsurface sediments
(Journal article; Peer reviewed, 2020)No other environment hosts as many microbial cells as the marine sedimentary biosphere. While the majority of these cells are expected to be alive, they are speculated to be persisting in a state of maintenance without net ... -
Geographic distribution, abundance, diet, and body size of invasive pink salmon (Oncorhynchus gorbuscha) in the Norwegian and Barents Seas, and in Norwegian rivers
(Journal article; Peer reviewed, 2022)We report for the first time the geographic distribution, abundance, diet, and body size of invasive pink salmon (Oncorhynchus gorbuscha) in the Norwegian and Barents Seas and Norwegian coast and rivers. We found that pink ... -
Geographic variation in gene flow from a genetically distinct migratory ecotype drives population genetic structure of coastal Atlantic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2022)Identifying how physical and biotic factors shape genetic connectivity among populations in time and space is essential to our understanding of the evolutionary trajectory as well as the management of marine species. ... -
Geographical and management related factors affecting lambs of outwintered sheep along the west coast of Norway. A baseline study in the research project feral sheep in coastal heats - developing a sustainable local industry in vulnerable cultural landscapes
(Master thesis, 2008)The Ancient Norse breed of outwintered sheep (ANBOS/Feral sheep) are the traditional sheep of Norwegian coastal heathlands, an open semi-natural landscape now threatened by regrowth due to cessation of management. One of ... -
Geomicrobial characterisation of a 60 m long permafrost core, taken over a future CO2 storage site at Svalbard
(Master thesis, 2014-09-11)In connection with a planned CO2 storage pilot project in the Arctic, a 60 m long permafrost core was drilled in Adventdalen, Svalbard, representing the poorly studied deep permafrost ecosystems. The on-shore drilling was ... -
Geomorphological processes shape plant community traits in the Arctic
(Journal article; Peer reviewed, 2022)Aim Geomorphological processes profoundly affect plant establishment and distributions, but their influence on functional traits is insufficiently understood. Here, we unveil trait–geomorphology relationships in Arctic ... -
Germination and seedling growth of Calluna vulgaris is sensitive to regional climate, heathland succession, and drought
(Journal article; Peer reviewed, 2023)The coastal heathlands of Northwest Europe are highly valued cultural landscapes, that are critically endangered due to land use and climatic changes, such as increased frequency and severity of drought events. Our study ... -
Germination ecology of the clonal grassland herb Knautia arvensis: Regeneration strategy and geographic variation.
(Peer reviewed; Journal article, 2003)We investigated germination responses and seed recruitment in the clonal grassland herb Knautia arvensis (Dipsacaceae) throughout the species’ distributional range in Norway. Four predicted relationships between germination ... -
Giant sponge grounds of Central Arctic seamounts are associated with extinct seep life
(Journal article; Peer reviewed, 2022)The Central Arctic Ocean is one of the most oligotrophic oceans on Earth because of its sea-ice cover and short productive season. Nonetheless, across the peaks of extinct volcanic seamounts of the Langseth Ridge (87°N, ... -
Gill and labial palp areas in blue mussels (Mytilus edulis) at sites with different food quantity
(Master thesis, 2013-06-01)Suspension feeding bivalves captures and process particles with their gills and labial palps. These foraging apparatus are known to be flexible in size related to seston quantity and quality. It is important to understand ... -
The gill parasite Paramoeba perurans compromises aerobic scope, swimming capacity and ion balance in Atlantic salmon
(Peer reviewed; Journal article, 2017-01)The parasitic amoeba Paramoeba perurans is an aetiological agent of amoebic gill disease (AGD), a serious problem in seawater salmonid aquaculture globally. Other finfish species are also infected and infection events may ... -
Giving eyes to pelagic trawls: Acoustic and optical techniques measure behaviour, species, and sizes of fish in situ
(Doctoral thesis, 2013-11-26)Trawling, towing a cone-shaped net behind a moving boat, is a widespread fishing method both in commercial fisheries and to collect fish for scientific investigations. It combines filtering effect with herding behaviour ... -
Glacial microbiota are hydrologically connected and temporally variable
(Journal article; Peer reviewed, 2020)Glaciers are melting rapidly. The concurrent export of microbial assemblages alongside glacial meltwater is expected to impact the ecology of adjoining ecosystems. Currently, the source of exported assemblages is poorly ... -
