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, ... -

Spring bloom nutrient dynamics in the Oslofjord
(Journal article; Peer reviewed, 2001-09-10)Primary production and uptake rates of ammonium, nitrate and silicic acid were measured during the 1996 spring bloom in the Oslofjord, southern Norway, using isotope methodology (14C, 15N and 32Si). Chlorophyll a (chl a) ... -
Spring bloom onset in the Nordic Seas
(Journal article; Peer reviewed, 2016-06-15)The North Atlantic spring bloom is a massive annual growth event of marine phytoplankton, tiny free-floating algae that form the base of the ocean's food web and generates a large fraction of the global primary production ... -
Stability of an infectious pancreatic necrosis virus (IPNV) isolate stored under different laboratory conditions
(Journal article; Peer reviewed, 1998-05-14)An infectious pancreatic necrosis virus (IPNV) belonging to the Sp serotype, isolated from scallops Pecten maximus, was propagated and suspended in sterile water and cell culture medium with different salinities and incubated ... -
Stabilizing selection on Atlantic cod supergenes through a millennium of extensive exploitation
(Peer reviewed; Journal article, 2022)Life on Earth has been characterized by recurring cycles of ecological stasis and disruption, relating biological eras to geological and climatic transitions through the history of our planet. Due to the increasing degree ... -

Stable coexistence of genetically divergent Atlantic cod ecotypes at multiple spatial scales
(Journal article; Peer reviewed, 2018)Coexistence in the same habitat of closely related yet genetically different populations is a phenomenon that challenges our understanding of local population structure and adaptation. Identifying the underlying mechanisms ... -
Stable isotope marking of otoliths during vaccination: a novel method for mass-marking fish
(Journal article; Peer reviewed, 2014-06-04)Tagging or marking of fishes enables the collection of population-based information for ecological research, yet few techniques enable 100% mark detection success. We tested a new mass-marking technique: otolith marking ... -
A standard protocol for describing the evaluation of ecological models
(Peer reviewed; Journal article, 2022)Numerical models of ecological systems are increasingly used to address complex environmental and resource management questions. One challenge for scientists, managers, and stakeholders is to appraise how well suited these ... -

A Standardized Workflow Based on the STAVIRO Unbaited Underwater Video System for Monitoring Fish and Habitat Essential Biodiversity Variables in Coastal Areas
(Peer reviewed; Journal article, 2021)Essential Biodiversity Variables (EBV) related to benthic habitats and high trophic levels such as fish communities must be measured at fine scale but monitored and assessed at spatial scales that are relevant for policy ... -
Standing stock of Antarctic krill (Euphausia superba Dana, 1850) (Euphausiacea) in the Southwest Atlantic sector of the Southern Ocean, 2018-19
(Peer reviewed; Journal article, 2021)Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean ... -
Statistical and ecological challengesof monitoring parasitic salmon lice infestationsin wild salmonid fish stocks
(Journal article; Peer reviewed, 2015-12-03)Ecological monitoring programmes should provide precise data to inform management, but the data quality is often limited by methodological challenges and the need for cost-effective sampling. Parasite infestations are ... -
Statistical modelling of voluntary feed intake in individual Atlantic salmon (Salmo salar L.)
(Others, 2023)Precision feeding aims to provide the correct amount of feed to farmed animals for optimal growth and performance and to avoid feed waste. However, knowledge underlying the meal-to-meal variability in voluntary feed intake ...
