Caught in the act: phenotypic consequences of a recent shift in feeding strategy of the shark barnacle Anelasma squalicola (Lovén, 1844)
(Peer reviewed; Journal article, 2016-03)Anelasma squalicola is a barnacle found attached to deep-water lantern sharks of the family Etmopteridae and is the only known cirriped on fish hosts. While A. squalicola is equipped with mouth and thoracic appendages ... -
Causes of Mortality and Loss of Lumpfish Cyclopterus lumpus
(Journal article; Peer reviewed, 2022)Data from research and commercial use of lumpfish were collected from the research facilities of Gifas (Inndyr, Northern Norway, 67.0° N, 14.0° E). The data were sourced from 12 main lumpfish groups subdivided into 66 ... -
Cell cycle regulation of Oikopleura dioica. A study of the cyclin CDK-complement
(Doctoral thesis, 2014-11-14)Regulation of the eukaryotic cell cycle is a fundamental biological process which controls proliferation of all eukaryote cells. Progression through the cell cycle is highly dependent on its core regulators; Cyclins and ... -
Cell size of Antarctic phytoplankton as a biogeochemical condition
(Peer reviewed; Journal article, 2009)Two contrasting high nutrient/low chlorophyll regions having different conditions that control phytoplankton production, and separated by an area of blooming, are found during summer in the vicinity of the South Shetland ... -
Centennial changes in water clarity of the Baltic Sea and the North Sea
(Peer reviewed; Journal article, 2013-10-10)Secchi depth is a valuable proxy for detecting long term changes in the water clarity of oceanic and coastal ecosystems. We analyse approximately 40 000 observations, which are available from ICES, from the Baltic Sea and ... -
Centennial decline in North Sea water clarity causes strong delay in phytoplankton bloom timing
(Peer reviewed; Journal article, 2019-08-23)With climate warming, a widespread expectation is that events in spring, such as flowering, bird migrations, and insect bursts, will occur earlier because of increasing temperature. At high latitudes, increased ocean ... -
Centennial relationships between ocean temperature and Atlantic puffin production reveal shifting decennial trends
(Journal article; Peer reviewed, 2021)The current warming of the oceans has been shown to have detrimental effects for a number of species. An understanding of the underlying mechanisms may be hampered by the non-linearity and non-stationarity of the relationships ... -
A century of fish growth in relation to climate change, population dynamics and exploitation
(Journal article; Peer reviewed, 2020)Marine ecosystems, particularly in high‐latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes ... -
Century-long cod otolith biochronology reveals individual growth plasticity in response to temperature
(Journal article; Peer reviewed, 2020)Otolith biochronologies combine growth records from individual fish to produce long-term growth sequences, which can help to disentangle individual from population-level responses to environmental variability. This study ... -
Cerebral gene expression and neurobehavioural development after perinatal exposure to an environmentally relevant polybrominated diphenylether (BDE47)
(Peer reviewed; Journal article, 2011-06-02)Nutrients in seafood are known to be beneficial for brain development. Effects of maternal exposure to 2,2′,4,4′ tetrabromo diphenylether (BDE47) was investigated, alongside the potential ameliorating impact of seafood ... -
Cestodes in Atlantic salmon (Salmo salar L.) at a W Norwegian hatchery: Infection dynamics, aspects of development and pathology
(Master thesis, 2003)Many cestodes use copepods as first intermediate hosts, and some may infect juvenile salmonids in hatcheries that use water from sources that are inhabited by native salmonids. Little is known about their infection dynamics ... -
Challenge model for Pasteurella atlantica genomovar salmonicida in Atlantic salmon (Salmo salar L.)
(Master thesis, 2022-06-01)Pasteurellose i Atlantisk laks (Salmo salar L.) har blitt et problem i Norge de siste årene. I fiskehelserapporten fra 2021 karakteriserte Veterinærinstituttet (VI) for første gang pasteurellose i Atlantisk laks som en ... -
Challenges related to delivery of water soluble nutrients to marine fish larvae. Evaluation of changes in nutritional quality due to production process and leaching from larval diets -with emphasis on protein quality
(Doctoral thesis, 2007-06-26)Marine fish larvae fed formulated diets have suppressed growth and survival compared to larvae fed live feed for the first weeks. Live feed is successfully used in the aquaculture industry, although there are difficulties ... -
Change and variation in a hyer-arid cultural landscape: A merhodological approach using remote sensing timeseries (Landsat MSS and TM, 1973-1996) from the Wadi vegetation of the eastern desert of Egypt
(Master thesis, 1999)Nine wadi localities in a hyper-arid environment have been registered in the field and studied using earth observation data. Branch height, crown – and trunk – diameter, and indicators of land-use such as present traces ... -
Changes in circulating insulin-like growth factor-1 and its binding proteins in yearling rainbow trout during spring under natural and manipulated photoperiods and their relationships with gill Na+, K+-ATPase and body size
(Journal article; Peer reviewed, 2022)Smoltification in salmonids occurs during spring in response to increasing photoperiod to prepare for marine life. Smoltification is associated with increased hypo-osmoregulatory ability and enhanced growth potential, ... -
Changes in gill Na+K+ATPase alfa subunit isoform expression during smoltification and in maturing male Atlantic salmon
(Master thesis, 2011-06-22)Distinct freshwater and seawater chloride cells have been identified in salmon gills and recent studies also suggest that there are specific freshwater (α1a) and seawater (α1b) isoforms of the α subunit ... -
Changes in histidine metabolism through smoltification and effect on cataract development in Atlantic Salmon (Salmo salar L.)
(Master thesis, 2021-01-20)Cataract is the collective definition of any light scattering opacities of the eye. Cataractogenesis is caused when there is a noticeable irregular light scattering because there has been a change in the tridimensional ... -
Changes in marine prokaryote composition with season and depth over an Arctic polar year
(Peer reviewed; Journal article, 2017-04-13)As the global climate changes, the higher latitudes are seen to be warming significantly faster. It is likely that the Arctic biome will experience considerable shifts in ice melt season length, leading to changes in ... -
