Spatio-temporal turnover and drivers of bentho-demersal community and food web structure in a high-latitude marine ecosystem
(Peer reviewed; Journal article, 2022)Assess the spatial and temporal turnover of bentho-demersal marine fauna by integrating ecological metrics at the community and food web levels and evaluate their main environmental and anthropogenic drivers. -
Spatiotemporal variability of barium in arctic sea-ice and seawater
(Journal article; Peer reviewed, 2018)Freshwater export from the Arctic is critical in determining the density of water at sites of North Atlantic deep water formation, which in turn influences the global flux of oceanic heat and nutrients. We need geochemical ... -
Spatiotemporal variation in climatic conditions across ecosystems
(Peer reviewed; Journal article, 2021)Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ... -
Spatiotemporal variation in climatic conditions across ecosystems
(Peer reviewed; Journal article, 2021)Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ... -
Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site
(Peer reviewed; Journal article, 2022)Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ... -
Spawning energetics and otolith microchemistry provide insights into the stock structure of bonga shad Ethmalosa fimbriata
(Journal article; Peer reviewed, 2019)The gross energy content of spawning batches and the microchemistry of sagittal otoliths in individual female bonga shad Ethmalosa fimbriata were compared between contrasting sampling sites at the Senegalese southern coast ... -
Spawning manipulation, broodfish diet feeding and egg production in farmed Atlantic salmon
(Peer reviewed; Journal article, 2024)Atlantic salmon aquaculture relies on continuous supply of high quality eggs. Broodfish nutrition and manipulation of ovulation time (photoperiod and temperature) are key factors. The optimum feeding period with broodfish ... -
Spawning stock and recruitment in North Sea cod shaped by food and climate
(Journal article; Peer reviewed, 2010-09-01)In order to provide better fisheries management and conservation decisions, there is a need to discern the underlying relationship between the spawning stock and recruitment of marine fishes, a relationship which is ... -
Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability
(Peer reviewed; Journal article, 2023)Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key ... -
Speciation analysis of organoarsenic species in marine samples: method optimization using fractional factorial design and method validation
(Peer reviewed; Journal article, 2021)Organoarsenic species in marine matrices have been studied for many years but knowledge gaps still exist. Most literature focuses on monitoring of arsenic (As) species using previously published methods based on anion- and ... -
Speciation of zinc in fish feed by size exclusion chromatography coupled to inductively coupled plasma mass spectrometry – using fractional factorial design for method optimisation and mild extraction conditions
(Journal article; Peer reviewed, 2018)Zinc (Zn) is an element essential to all living organisms and it has an important role as a cofactor of several enzymes. In fish, Zn deficiency has been associated with impaired growth, cataracts, skeletal abnormalities ... -
Species composition of three size fractions of zooplankton used in routine monitoring of the Barents Sea ecosystem
(Peer reviewed; Journal article, 2021)Size fractionation with 2000 and 1000 μm screens is used by the Institute of Marine Research in Norway in routine monitoring of zooplankton biomass. This study examines the separation of taxa by this procedure. For copepods ... -
Species separation efficiency and effect of artificial lights with a horizonal grid in the Basque bottom trawl fishery
(Peer reviewed; Journal article, 2022)Achieving effective size selectivity for different species within a fishing gear is a major challenge in mixed fisheries. Fish behaviour may be exploited to separate species into separate codends where different selective ... -
Species-specific discrimination of insect meals for aquafeeds by direct comparison of tandem mass spectra
(Journal article; Peer reviewed, 2019)Insect protein has the potential to become a sustainable feed ingredient for the rapidly growing aquaculture industry. In the European Union, insect derived protein is placed under the same legislation as processed animal ... -
The specification of the data model part in the SAM model matters
(Peer reviewed; Journal article, 2020)This paper considers a general state-space stock assessment modeling framework that integrates a population model for a fish stock and a data model. This way observed data are linked to unobserved quantities in the population ... -
Speed of sound in Euphausia superba
(Journal article; Peer reviewed, 1990)The speed of longitudinal sound waves in Antarctic krill has been measured by the time-of-flight method. The result of 17 separate measurement series on different assemblages of living krill is that the animal's sound speed ... -
Sperm characteristics and competitive ability in farmed and wild cod
(Journal article; Peer reviewed, 2009-01-27)The development of cod aquaculture has raised concerns about its effect on wild stocks. One risk is hybridisation between escapees and wild cod, causing genetic introgression, and, potentially, fitness depressions in wild ... -
Spermatogonial Stem Cell Niche and Spermatogonial Stem Cell Transplantation in Zebrafish
(Journal article; Peer reviewed, 2010-09-20)Background Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis, and reside within a specific microenvironment in the testes called “niche” which regulates stem cell properties, such as, self-renewal, ... -
