Birth-date selection in early life stages of plaice Pleuronectes platessa in the eastern Irish Sea (British Isles)
(Journal article; Peer reviewed, 2007-09-13)For species with extended spawning seasons, short periods of beneficial conditions often lead to disproportionate survival of sub-sets of the offspring. This has been demonstrated for freshwater fish and for marine pelagic ... -
Blind dating—mate finding in planktonic copepods. I. Tracking the pheromone trail of Centropages typicus
(Journal article; Peer reviewed, 2005-09-16)Mate-finding behaviour in the marine copepod Centropages typicus was investigated by 3-dimensional video analysis. Females leave a chemical trail in their wake and a male intercepting a fresh trail initiates a characteristic ... -
Blind dating—mate finding in planktonic copepods. II. The pheromone cloud of Pseudocalanus elongatus
(Journal article; Peer reviewed, 2005-09-16)Receptive females of Pseudocalanus elongatus, like many other planktonic copepods, produce pheromones to signal their presence and position to males, and thus enhance the rate of mate encounter. By means of 3D video ... -
Blind dating—mate finding in planktonic copepods. III. Hydromechanical communication in Acartia tonsa
(Journal article; Peer reviewed, 2005-09-16)Mate-finding behaviour in the marine copepod Acartia tonsa was examined by video analysis. A. tonsa appears to depend on hydromechanical signals in the location of mates, detected at distances of up to 5 or 7 mm. Series ... -
Body size adaptions under climate change: Zooplankton community more important than temperature or food abundance in model of a zooplanktivorous fish
(Peer reviewed; Journal article, 2020)One of the most well-studied biogeographic patterns is increasing body size with latitude, and recent body size declines in marine and terrestrial organisms have received growing attention. Spatial and temporal variation ... -
Bridging the gap between aquatic and terrestrial ecology
(Journal article; Peer reviewed, 2005-12-08) -
Can predator avoidance explain varying overwintering depth of Calanus in different oceanic water masses?
(Journal article; Peer reviewed, 1999-04-15)Distributions of overwintering Calanus spp. in the upper 1000 m in the Norwegian and Greenland Seas were studied in relation to hydrography, invertebrate predators and acoustic scattering layers (38 kHz). C, finmarchicus ... -
Can silicate and turbulence regulate the vertical flux of biogenic matter? A mesocosm study
(Journal article; Peer reviewed, 2001-07-31)The effects of silicate and turbulence on the vertical flux of biogenic matter were studied in mesocosms. The experiment consisted of eight 27 m3 enclosures all fertilised with nitrate and phosphate (NP), while 4 of the ... -
Cascading effects of the ctenophore Mnemiopsis leidyi on the planktonic food web in a nutrient-limited estuarine system
(Journal article; Peer reviewed, 2012-07-24)Increasing biomasses of gelatinous zooplankton presumably have major implications for the structure and function of marine food webs at large; however, current data on lower trophic levels are scarce, as most studies ... -
Climatic and environmental factors influencing occurrence and distribution of macroalgae – a fjord gradient revisited
(Journal article; Peer reviewed, 2015-07-21)During the last decades, trends of increasing sea water temperatures and precipitation have been observed in the North Atlantic. Increasing sea water temperatures are expected to have strong effects on coastal benthic ... -
Climatic and environmental factors influencing occurrence and distribution of macroalgae – a fjord gradient revisited
(Peer reviewed; Journal article, 2015) -
Coastal salmon farms attract large and persistent aggregations of wild fish: an ecosystem effect
(Journal article; Peer reviewed, 2009-06-18)Coastal aquaculture is a globally expanding enterprise. Currently, 1200 salmon farms operate in coastal Norway, yet their capacity to aggregate and subsequently modify wild fish distributions is poorly known. Aggregations ... -
Coastal water darkening and implications for mesopelagic regime shifts in Norwegian fjords
(Journal article; Peer reviewed, 2009-07-28)The light regime of the water column has a strong structuring effect on aquatic food webs and it has been previously hypothesized that coastal water darkening has increased the success of tactile predators relative to ... -
Cod and climate: effect of the North Atlantic Oscillation on recruitment in the North Atlantic
(Journal article; Peer reviewed, 2006-11-07)The impact of the environment on interannual variability in fish recruitment has proven difficult to establish empirically, and environment-recruitment correlations have often been found to break down when more data become ... -
Common temperature-growth dependency and acclimation response in three herbivorous protists
(Peer reviewed; Journal article, 2020)Phytoplankton growth dependence on temperature is recognized and has been quantified comprehensively. However, no similar relationship exists for the major phytoplankton predators, the herbivorous protists, especially at ... -
Consumption of silicic acid below the euphotic zone by sedimenting diatom blooms in the Barents Sea
(Journal article; Peer reviewed, 1987-03-23)Massive sedimentation of spring phytoplankton blooms occurs in the Barents Sea as in many other shelf sea environments. Associated with this sedimentation there is a large decrease in concentration of dissolved shcic ... -
Correcting for underestimation of microzooplankton grazing in bottle incubation experiments with mesozooplankton
(Journal article; Peer reviewed, 2001-10-18)Bottle incubation experiments are widely used in mesozooplankton grazing studies. However, we have shown here that traditional particle removal experiments with Calanus finmarchicus and C. helgolandicus as grazers on ... -
The 'critical period' concept - a century of recruitment research
(Others, 1995-11-23) -
Demersal assemblages of the continental shelf and slope edge between the Gulf of Tehuantepec (Mexico) and the Gulf of Papagayo (Costa Rica)
(Journal article; Peer reviewed, 1991-07-11)The structure of demersal assemblages (fish, crustaceans and cephalopods) of the continental shelf and upper slope between the Gulf of Tehuantepec and the Gulf of Papagayo was studied from data obtained in the course of ... -
Demersal assemblages of the continental shelf and upper slope of Angola
(Journal article; Peer reviewed, 1992-04-21)The structure of the demersal assemblages (fish, crustaceans and cephalopods) of the continental shelf and upper slope of Angola (ca 5 to 17-degrees-S) was studied based on the trawl survey of the RV `Dr. Fridtjof Nansen' ...
