Stability in Ecosystem Functioning across a Climatic Threshold and Contrasting Forest Regimes
(Peer reviewed; Journal article, 2011-01-18)Classical ecological theory predicts that changes in the availability of essential resources such as nitrogen should lead to changes in plant community composition due to differences in species-specific nutrient requirements. ... -
Standard Binding Free Energy and Membrane Desorption Mechanism for a Phospholipase C
(Journal article; Peer reviewed, 2022)Peripheral membrane proteins (PMPs) bind temporarily to cellular membranes and play important roles in signaling, lipid metabolism, and membrane trafficking. Obtaining accurate membrane-PMP affinities using experimental ... -
State-dependent spatial and intra-school dynamics in pre-spawning herring (Clupea harengus L.) in a semi-enclosed ecosystem
(Peer reviewed; Journal article, 2013)Distribution and aggregation patterns of pelagic fish in marine ecosystems are hard to predict and understand, particularly since focused studies are typically limited to single field efforts. Our study targets coastal ... -
Statistical modelling of voluntary feed intake in individual Atlantic salmon (Salmo salar L.)
(Journal article, 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 ... -
Stem cell biology is population biology: differentiation of hematopoietic multipotent progenitors to common lymphoid and myeloid progenitors
(Peer reviewed; Journal article, 2013-01-17)The hematopoietic stem cell (HSC) system is a demand control system, with the demand coming from the organism, since the products of the common myeloid and lymphoid progenitor (CMP, CLP respectively) cells are essential ... -
Stepwise temperature regulation and its effect on growth, feeding and muscle growth patterns of juvenile Atlantic halibut (Hippoglossus hippoglossus L.)
(Peer reviewed; Journal article, 2010)To investigate the possible direct effect of a stepwise reduction in temperature with increasing size on growth, feeding parameters and muscle growth patterns of juvenile Atlantic halibut (Hippoglossus hippoglossus L.), ... -
“Stewards of the future: accompanying the rising tide of young voices by setting youth-inclusive research agendas in sustainability research”
(Journal article; Peer reviewed, 2021)Background From the worldwide youth-led climate strikes of 2018–2019 to the student-initiated austerity protests in Chile in 2019, it is undeniable that young people have been protagonists in pressuring for social change ... -
Stimulation of MCM helicase activity by a Cdc6 protein in the archaeon Thermoplasma acidophilum
(Peer reviewed; Journal article, 2006-11-15)Replicative DNA helicases are ring-shaped hexamers that play an essential role in chromosomal DNA replication. They unwind the two strands of the duplex DNA and provide the single-stranded (ss) DNA substrate for the ... -
Stochastic dynamics of interacting haematopoietic stem cell niche lineages
(Peer reviewed; Journal article, 2014-09-04)Since we still know very little about stem cells in their natural environment, it is useful to explore their dynamics through modelling and simulation, as well as experimentally. Most models of stem cell systems are based ... -
Stocking density and its influence on the productivity of red cusk eel, Genypterus chilensis (Guichenot, 1848), in shallow raceways
(Journal article; Peer reviewed, 2020)We compared the growth properties of red cusk eel Genypterus chilensis with initial mean weight ± standard error, 106.2 ± 6.1 g reared in shallow raceways at three different stocking densities (28.5, 46.1, and 60.7 kg m-3) ... -
Stocking density limits for post-smolt Atlantic salmon (Salmo salar L.) emphasis on production performance and welfare
(Peer reviewed; Journal article, 2017-02)For the development of commercial scale semi-closed sea systems for farming post-smolt Atlantic salmon (Salmo salar), further knowledge is required on the interaction between fish density, farming conditions and fish ... -
Stoichiometric consequences of size-selective mortality: An experimental test using the Japanese medaka (Oryzias latipes)
(Journal article; Peer reviewed, 2020-07-01)The determinants of intraspecific stoichiometric variation remain difficult to elucidate due to their multiple ori- gins (e.g. genetic vs. environmental) and potential interactive effects. We evaluated whether two size-selected ... -
Strategies for partition between reproductive investment and body growth in stationary and migratory stocks of Atlantic herring
(Master thesis, 2011-06-01)The present study focused on the trade-off between reproductive investment and body growth of migratory and stationary Atlantic herring (Clupea harengus) populations. Published data from Norwegian spring-spawning (NSS) ... -
Strategies Used Throughout the World to Manage Fisheries Discards – Lessons for Implementation of the EU Landing Obligation
(Chapter; Peer reviewed, 2019)In many countries, policies regarding reduction of unwanted catch and discards are crafted in response to concerns regarding accountability, conservation, and waste as well as scientific needs to fully account for all ... -
Strengthening the evidence base for temperature-mediated phenological asynchrony and its impacts
(Journal article; Peer reviewed, 2021)Climate warming has caused the seasonal timing of many components of ecological food chains to advance. In the context of trophic interactions, the match–mismatch hypothesis postulates that differential shifts can lead to ... -
Stress Response and Recovery in Atlantic Salmon (Salmo salar L.) Fed Diets Low in the Marine n-3 Fatty Acids EPA and DHA
(Master thesis, 2014-06-01)With the fast growth of today's aquaculture industry, the demand for aquafeeds is expanding dramatically. Finding sustainable alternative sources to fishmeal and fish oil (FO) is becoming an urgent issue; vegetable oil ... -
The stress response in Atlantic salmon (Salmo salar L.): identification and functional characterization of the corticotropin-releasing factor (crf) paralogs
(Journal article; Peer reviewed, 2021)Corticotropin-Releasing Factor (CRF) is one of the main mediators of the Hypothalamic-Pituitary–Interrenal (HPI) axis to stress response. In Atlantic salmon, a comparative understanding of the crf1 paralogs role in the ... -
