Age-structure, harvesting and climate effects on population growth of Arcto-boreal fish stocks
(Journal article; Peer reviewed, 2017)We used a comparative approach investigating commercially fished species with contrasting life histories and trophic positions in an Arcto-boreal system, the Barents Sea. Our objective was to address the ecological ... -
Associations between timing and magnitude of spring blooms and zooplankton dynamics in the southwestern Barents Sea
(Peer reviewed; Journal article, 2021)During the past decades, many high-latitude marine systems have experienced a strong warming trend with poorly understood consequences for trophic coupling and ecosystem functioning. A key knowledge gap is how timing and ... -
Effects of climate and eutrophication on the diversity of hard bottom communities on the Skagerrak coast 1990-2010
(Journal article; Peer reviewed, 2015)Eutrophication is one of the most serious environmental problems in the Skagerrak, and climate change may increase eutrophication in the future. This study focused on the effects of eutrophication and climate, and the ... -
Effects of CO2 on growth rate, C:N:P, and fatty acid composition of seven marine phytoplankton species
(Journal article; Peer reviewed, 2015)Carbon dioxide (CO2) is the primary substrate for photosynthesis by the phytoplankton that form the base of the marine food web and mediate biogeochemical cycling of C and nutrient elements. Specific growth rate and elemental ... -
Effects of increased irradiance on biomass, photobiology, nutritional quality, and pigment composition of Arctic sea ice algae
(Peer reviewed; Journal article, 2020)Ice algae are key contributors to primary production and carbon fixation in the Arctic, and light availability is assumed to limit their growth and productivity. We investigated photo-physiological responses in sea ice ... -
Faunal trophic structure at hydrothermal vents on the southern Mohn's Ridge, Arctic Ocean
(Journal article; Peer reviewed, 2013)We explore the trophic ecology of heterotrophic fauna associated with a high temperature (HT) vent, 2 low temperature vents, a ‘near-HT vent’ habitat and a non-vent site situated at upper bathyal depths on the southern ... -
Impacts of salmon lice on mortality, marine migration distance and premature return in sea trout
(Peer reviewed; Journal article, 2020)Brown trout Salmo trutta (L.) is a facultative anadromous species, where a portion of individuals in populations with access to the sea perform migrations to use the richer feeding resources. We investigated the effect of ... -
Lack of sea urchin settlement may explain kelp forest recovery in overgrazed areas in Norway
(Journal article; Peer reviewed, 2013)In this study, we investigated whether failure of sea urchin recruitment can explain an ongoing phase shift from overgrazed, barren grounds to kelp forests along the coast of mid- Norway. Settlement of sea urchins on ... -
Length, strength and water flow: relative importance of wave and current exposure on morphology in kelp Laminaria hyperborea
(Journal article; Peer reviewed, 2014)Water flow is a strong determinant of kelp growth, but it is also a stress factor causing breakage and dislodgement. As wave exposure and currents differ with respect to flow pattern, the 2 forces are expected to affect ... -
Microbial degradation dynamics of farmed kelp deposits from Saccharina latissima and Alaria esculenta
(Peer reviewed; Journal article, 2023)Seaweed farming is a growing industry worldwide, and its sustainable management requires detailed knowledge about the environmental implications of detrital release. This study investigates benthic degradation of kelp ... -
Predators of the destructive sea urchin grazer Strongylocentrotus droebachiensis on the Norwegian coast
(Journal article; Peer reviewed, 2014)In central Norway, populations of the green sea urchin Strongylocentrotus droe-bachiensis are collapsing, but the factors controlling its population density have not yet been elucidated. Through field sampling, we identified ...
