Laksvel - Standardisert operasjonell velferdsovervåking for laks i matfiskanlegg
(Rapport fra havforskningen;2022 - 14, Research report, 2022-05-30)Selv om oppdrettere og fiskehelsepersonell har undersøkt og dokumentert velferden til laksen har det ikke funnes noen standardisert måte å gjøre dette på. Denne protokollen er laget for å kunne brukes som en felles ... -
Large annual variation in the amount of skipped spawning for female Northeast Arctic haddock Melanogrammus aeglefinus
(Peer reviewed; Journal article, 2020)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ... -

Large scale patches of Calanus finmarchicus and associated hydrographic conditions off the Lofoten archipelago
(Peer reviewed; Journal article, 2022)Large swarms of individuals at different spatiotemporal scales characterise the distributions of many animal species. In the ocean several mesozooplankton taxa aggregate in large patches or swarms driven by active behavioural ... -
Large scale patterns in vertical distribution and behaviour of mesopelagic scattering layers
(Journal article; Peer reviewed, 2016-01-27)Recent studies suggest that previous estimates of mesopelagic biomasses are severely biased, with the new, higher estimates underlining the need to unveil behaviourally mediated coupling between shallow and deep ocean ... -
Large-effect loci mediate rapid adaptation of salmon body size after river regulation
(Peer reviewed; Journal article, 2022)Understanding the potential of natural populations to adapt to altered environments is becoming increasingly relevant in evolutionary research. Currently, our understanding of adaptation to human alteration of the environment ... -

Large-scale culturing of Neogloboquadrina pachyderma, its growth in, and tolerance of, variable environmental conditions
(Peer reviewed; Journal article, 2023)The planktic foraminifera Neogloboquadrina pachyderma is a calcifying marine protist and the dominant planktic foraminifera species in the polar oceans, making it a key species in marine polar ecosystems. The calcium ... -

Large-scale culturing of the subpolar foraminifera Globigerina bulloides reveals tolerance to a large range of environmental parameters associated to different life-strategies and an extended lifespan
(Peer reviewed; Journal article, 2024)The subtropical to subpolar planktic foraminifera Globigerina bulloides is a calcifying marine protist, and one of the dominant foraminiferal species of the Nordic Seas. Previously, the relative abundance and shell ... -
Large-scale patterns in community structure of benthos and fish in the Barents Sea
(Journal article; Peer reviewed, 2016-04-23)Biogeographical patterns have an ecological basis, but few empirical studies possess the necessary scale and resolution relevant for investigation. The Barents Sea shelf provides an ideal study area, as it is a transition ... -
Large-scale salmon farming in Norway impacts the epiphytic community of Laminaria hyperborea
(Peer reviewed; Journal article, 2021)Large-scale finfish farms are increasingly located in dispersive hard-bottom environments where Laminaria hyperborea forests dominate; however, the interactions between farm effluents and kelp forests are poorly understood. ... -
Large-scale seabird community structure along oceanographic gradients in the Scotia Sea and northern Antarctic Peninsula
(Peer reviewed; Journal article, 2023)The Scotia Sea and Antarctic Peninsula are warming rapidly and changes in species distribution are expected. In predicting habitat shifts and considering appropriate management strategies for marine predators, a community-level ... -

Late summer sea ice segmentation with multi-polarisation SAR features in C- and X-band
(Journal article; Peer reviewed, 2016-02-17)In this study, we investigate the potential of sea ice segmentation by C- and X-band multi-polarisation synthetic aperture radar (SAR) features during late summer. Five high-resolution satellite SAR scenes were recorded ... -

Latent Gaussian models to predict historical bycatch in commercial fishery
(Peer reviewed; Journal article, 2017)Knowledge about how many fish that have been killed due to bycatch is an important aspect of ensuring a sustainable ecosystem and fishery. We introduce a Bayesian spatio-temporal prediction method for historical bycatch ...
