Seasonal and diel variation in greenhouse gas emissions from an urbanpond and its major drivers
(Peer reviewed; Journal article, 2019-09)Small water systems are important hotspots of greenhouse gas (GHG) emission, but estimates are poorly constrained as data are scarce. Small ponds are often constructed in urban areas, where they receive large amounts of ... -
Seasonal Changes in Photoperiod: Effects on Growth and Redox Signaling Patterns in Atlantic Salmon Postsmolts
(Journal article; Peer reviewed, 2023)Farmed Atlantic salmon reared under natural seasonal changes in sea-cages had an elevated consumption of antioxidants during spring. It is, however, unclear if this response was caused by the increase in day length, ... -
The seasonal cycle in the Atlantic transport to the Barents Sea during the years 1997–2001
(Peer reviewed; Journal article, 2004)The seasonal cycle in the Atlantic inflow to the Barents Sea is investigated by using 4-year long records from moored current meters, additional moorings of shorter duration, and hydrographic measurements. A higher transport ... -
Seasonal diversity and dynamics of haptophytes in the Skagerrak, Norway, explored by high-throughput sequencing
(Peer reviewed; Journal article, 2015-06)Microalgae in the division Haptophyta play key roles in the marine ecosystem and in global biogeochemical processes. Despite their ecological importance, knowledge on seasonal dynamics, community composition and abundance ... -
Seasonal dynamics and life histories of three sympatric species of Pseudocalanus in two Svalbard fjords
(Journal article; Peer reviewed, 2021)Small copepods are the most diverse and numerous group in high-latitude zooplankton, yet our knowledge of important species remains poor because of the difficulties involved in correct species identification. In this study, ... -
Seasonal dynamics of algae-infecting viruses and their inferred interactions with protists
(Peer reviewed; Journal article, 2019-11-09)Viruses are a highly abundant, dynamic, and diverse component of planktonic communities that have key roles in marine ecosystems. We aimed to reveal the diversity and dynamics of marine large dsDNA viruses infecting algae ... -
Seasonal dynamics of atlantic herring (Clupea harengus L.) populations spawning in the vicinity of marginal habitats
(Peer reviewed; Journal article, 2014-11-05)Gillnet sampling and analyses of otolith shape, vertebral count and growth indicated the presence of three putative Atlantic herring (Clupea harengus L.) populations mixing together over the spawning season February–June ... -
Seasonal dynamics of bacterial biofilms on the kelp Laminaria hyperborea
(Peer reviewed; Journal article, 2010-05)Seasonal variations of the cell density and bacterial community composition in biofilms growing on the surface of the kelp Laminaria hyperborea from 2 sites on the southwestern coast of Norway were investigated using total ... -
Seasonal dynamics of haptophytes and dsDNA algal viruses suggest complex virus-host relationship
(Peer reviewed; Journal article, 2017-04-20)Viruses influence the ecology and diversity of phytoplankton in the ocean. Most studies of phytoplankton host–virus interactions have focused on bloom-forming species like Emiliania huxleyi or Phaeocystis spp. The role of ... -
Seasonal dynamics of the vertical migration behaviour of mesopelagic fish
(Doctoral thesis, 2010-11-26)This thesis focuses on the behavioural dynamics of mesopelagic fish in a fjordic environment. Acoustic data recorded with a stationary echosounder was used to primarily investigate the diel vertical migration behaviour of ... -
Seasonal pollutant levels in littoral high-Arctic amphipods in relation to food sources and terrestrial run-off
(Journal article; Peer reviewed, 2022)Increasing terrestrial run-off from melting glaciers and thawing permafrost to Arctic coastal areas is expected to facilitate re-mobilization of stored legacy persistent organic pollutants (POPs) and mercury (Hg), potentially ... -
Seasonal Variability in Near-bed Environmental Conditions in the Vazella pourtalesii Glass Sponge Grounds of the Scotian Shelf
(Journal article; Peer reviewed, 2021)The Scotian Shelf harbors unique aggregations of the glass sponge Vazella pourtalesii that provides an important habitat for benthic and pelagic fauna. Recent studies have shown that these sponge grounds have persisted in ... -
Seasonal variations in C:N:Si:Ca:P:Mg:S:K:Fe relationships of seston from Norwegian coastal water: Impact of extreme offshore forcing during winter-spring 2010
(Peer reviewed; Journal article, 2017-11)The aim of this study was to reveal the relative content of C, N, Ca, Si, P, Mg, K, S and Fe in seston particles in Norwegian coastal water (NCW), and how it relates to biological and hydrographic processes during seasonal ... -
Seasonality of the Physical and Biogeochemical Hydrography in the Inflow to the Arctic Ocean Through Fram Strait
(Peer reviewed; Journal article, 2018-06-29)Eastern Fram Strait and the shelf slope region north of Svalbard is dominated by the advection of warm, salty and nutrient-rich Atlantic Water (AW). This oceanic heat contributes to keeping the area relatively free of ice. ... -
The seasonally dry tropical forest species Cavanillesia chicamochae has a middle Quaternary origin
(Journal article; Peer reviewed, 2021)We use DNA sequence data to understand the evolutionary history of the genus Cavanillesia (Malvaceae), with particular emphasis on C. chicamochae, an emblematic succulent-trunked tree endemic to seasonally dry tropical ... -
Secchi disk measurements in turbid water
(Journal article; Peer reviewed, 2020)In the classical theory of the Secchi disk depth, diffuse sunlight falling on the disk is reflected back to the observer's eye along the most direct route, as a beam. The disappearance depth, ZSD, of the disk is then ... -
Secretory vesicle protein homologues in choanoflagellates
(Doctoral thesis, 2023-12-15)Regulert vesikeleksocytose, som i tilfellet med høyt spesialisert synaptisk vesikelsekresjon, styres av et sett evolusjonært konserverte proteiner. Mange av disse proteinene er eldre enn dyrene. Målet med denne avhandlingen ... -
Sedation and slaughter of Atlantic salmon (Salmo salar, L.) with carbon monoxide, and a possible regulatory role of neuroglobin
(Doctoral thesis, 2012-10-05)Until recently CO2 has been utilized as an anesthetic method before gill cutting of Norwegian Atlantic salmon farmed fish. From 1. July 2012 this is no longer permitted in Norway since it causes strong aversive reactions ... -
Seed banks are biodiversity reservoirs: species–area relationships above versus below ground
(Peer reviewed; Journal article, 2015-05-26)Soil seed banks offer plants the possibility to disperse through time. This has implications for population and community dynamics, as recognised by ecological and evolutionary theory. In contrast, the conservation and ... -
