Sewage-based surveillance shows presence of Klebsiella pneumoniae resistant against last resort antibiotics in the population in Bergen, Norway
(Peer reviewed; Journal article, 2022)The aim of this study was to understand the prevalence of antibiotic resistance in Klebsiella pneumoniae present in the population in Bergen city, Norway using city-scale sewage-based surveillance, as well as the potential ... -
Sex differentiation in Atlantic cod (Gadus morhua L.): morphological and gene expression studies
(Journal article; Peer reviewed, 2012-06-18)Background In differentiated gonochoristic species, a bipotential gonad develops into an ovary or testis during sex differentiation. Knowledge about this process is necessary to improve methods for masculinizing genetically ... -
Sex steroid production associated with puberty is absent in germ cellfree salmon
(Peer reviewed; Journal article, 2017) -
Sexual and aggressive interactions in a mixed species group of lobsters Homarus gammarus and H. americanus
(Journal article; Peer reviewed, 2008-06-12)The introduction of non-native populations can have dramatic effects on the native fauna as a result of interbreeding and aggressive interference between closely related species. This study investigates if female European ... -
Sexual maturation and smoltification in domesticated Atlantic salmon (Salmo salar L.) - is there a developmental conflict?
(Journal article; Peer reviewed, 2018)We present data from two experiments that examined how the developmental processes of smoltification and sexual maturation proceed in parallel in domesticated Atlantic salmon. Onset of maturation and smoltification was ... -
Shaping sustainable harvest boundaries for marine populations despite estimation bias
(Peer reviewed; Journal article, 2021)Biased estimates of population status are a pervasive conservation problem. This problem has plagued assessments of commercial exploitation of marine species and can threaten the sustainability of both populations and ... -
Sharing the neighbourhood: assessing the impact of kelp harvest on foraging behaviour of the European shag
(Peer reviewed; Journal article, 2020)Coastal kelp forest ecosystems create dynamic and productive habitats, supporting a wide range of epiphytic flora, invertebrates, fish and seabirds. Worldwide, kelp is harvested commercially, affecting kelp-associated ... -
Shedding Light on Fish Otolith Biomineralization Using a Bioenergetic Approach
(Journal article; Peer reviewed, 2011-11-14)Otoliths are biocalcified bodies connected to the sensory system in the inner ears of fish. Their layered, biorhythm-following formation provides individual records of the age, the individual history and the natural ... -
Shelf recruitment of Calanus finmarchicus off the west coast of Norway: role of physical processes and timing of diapause termination
(Journal article; Peer reviewed, 2009-07-02)The copepod Calanus finmarchicus is an important part of the Norwegian Sea ecosystem because of its dominating abundance and importance as prey for fish larvae and adult planktivorous fish. The abundance of C. finmarchicus ... -
Shell density of planktonic foraminifera and pteropod species Limacina helicina in the Barents Sea: Relation to ontogeny and water chemistry
(Peer reviewed; Journal article, 2021)Planktonic calcifiers, the foraminiferal species Neogloboquadrina pachyderma and Turborotalita quinqueloba, and the thecosome pteropod Limacina helicina from plankton tows and surface sediments from the northern Barents ... -
Shelled pteropods in peril: Assessing vulnerability in a high CO2 ocean
(Peer reviewed; Journal article, 2017) -
Shield wall: Kelps are the last stand against corals in tropicalized reefs
(Peer reviewed; Journal article, 2022)Communities inhabiting biogeographic transition zones are shifting in composition as a result of progressive warming and heatwaves. In the marine environment, corals are expanding onto higher latitude reefs historically ... -
Shifting trophic control of fishery–ecosystem dynamics following biological invasions
(Peer reviewed; Journal article, 2020)Increasing human population size and mobility have accelerated the translocation of nonnative species globally, which has become a major threat to conservation of biodiversity and ecosystem services. Introduced species can ... -
Short-term exposure to hydrogen peroxide induces mortality and alters exploratory behaviour of European lobster (Homarus gammarus)
(Peer reviewed; Journal article, 2020)Bath treatment chemotherapeutants, used to control sea lice infestations in the salmonid aquaculture industry, are released directly into the marine environment around fish farms and pose a serious risk to non-target ... -
Short-term hydrographic variability in a stratified Arctic fjord
(Journal article; Peer reviewed, 2010)Fjords in the Arctic often have a more complex circulation pattern than the classical two dimentional estuarine circulation. This is due to the effects of the Earth’s rotation on stratified waters in wide fjords. Observations ... -
Shorter trawls improve size selection of northern shrimp
(Journal article; Peer reviewed, 2019)Discards of small northern shrimp (Pandalus borealis) are a problem in the Skagerrak northern shrimp trawl fishery. To reduce catches of small shrimp, we studied the effect of trawl belly length on size selectivity in ... -
Shotgun proteomics approaches for authentication, biological analyses, and allergen detection in feed and food-grade insect species
(Peer reviewed; Journal article, 2022)Untargeted proteomics can contribute to composition and authenticity analyses of highly processed mixed food and feed products. Here, we present the setup of an analytical flow tandem mass spectrometry method (AF-HPLC ... -
Signature of Arctic first-year ice melt pond fraction in X-band SAR imagery
(Peer reviewed; Journal article, 2017) -
Significance of advection for the carrying capacities of fjord populations
(Journal article; Peer reviewed, 1989-02-02)Advective rates of nutrients, phytoplankton and zooplankton were estimated for the Masfjord, western Norway, in June and October 1985. The advective contribution to the phytoplankton biomass formation was dearly less ...
