Arsenic speciation and arsenic feed-to-fish transfer in Atlantic salmon fed marine low trophic feeds based blue mussel and kelp
(Journal article; Peer reviewed, 2023)Background: Aquaculture aims to reduce the environmental and climate footprints of feed production. Consequently, low trophic marine (LTM) resources such as blue mussels and kelp are potential candidates to be used as ... -
Anthropogenic pollen indicators: Global food plants and Latin American human indicators in the pollen record
(Journal article; Peer reviewed, 2023)Pollen-based evidence of human presence is crucial for reconstructing human history. However, information on the morphology of pollen grains of global food plants and regional pollen-based human indicators is scattered in ... -
Evaluation of the efficacy of two Tenacibaculum vaccine prototypes in Atlantic salmon (Salmo salar) against T. maritimum challenge
(Master thesis, 2024-03-25)Mouthrot is a serious disease affecting recently sea launched Atlantic salmon (Salmo salar) smolt in British Columbia (Canada) and has been a well-known concern for decades. Still, it was just recently that Tenacibaculum ... -
Plant traits and associated data from a warming experiment, a seabird colony, and along elevation in Svalbard
(Journal article; Peer reviewed, 2023)The Arctic is warming at a rate four times the global average, while also being exposed to other global environmental changes, resulting in widespread vegetation and ecosystem change. Integrating functional trait-based ... -
Flower imprints from the history of mires and humans : A palynological study of rich fen development and periods of human land use over the last 8000 years in boreal Norway
(Doctoral thesis, 2024-06-25)Kulturvegetasjon på boreale slåttemyrer har for første gong vorte rekonstruert tilbake til den romerske jernalderen. Slåtten på myrene heldt fram til midten av 1900-talet i norske utmarker, og representerer ein del av den ... -
Prescribed burning can promote recovery of Atlantic coastal heathlands suffering dieback after extreme drought events
(Journal article; Peer reviewed, 2023)Questions During the winter of 2014, an intense drought combined with sub-zero temperatures resulted in a massive Calluna dieback in Norwegian heathlands. We studied the initial vegetation recovery under two management ... -
Methylacidiphilum kamchatkense gen. nov., sp. nov., an extremely acidophilic and moderately thermophilic methanotroph belonging to the phylum Verrucomicrobiota
(Journal article; Peer reviewed, 2023)The thermo-acidophilic aerobic methanotrophic Verrucomicrobia bacterium, designated strain Kam1T was isolated from an acidic geothermal mud spring in Kamchatka, Russia. Kam1T is Gram-stain-negative, with non-motile cells ... -
Evolution of the delta family of ionotropic glutamate receptors
(Doctoral thesis, 2024-06-14)I pattedyrhjernen er ionotrope glutamatreseptorer (iGluR) avgjørende for å formidle eksitatorisk nevrotransmisjon. Disse reseptorene deles inn i fire forskjellige familier: AMPA, KA, NMDA og delta. I motsetning til de andre ... -
Effects of migrating mesopelagic fishes on the biological carbon pump
(Journal article; Peer reviewed, 2023)Mesopelagic fishes and invertebrates contribute to the biological carbon pump (BCP) through direct and indirect effects on the gravitational, diffusive, and migrant (active) fluxes. Here, we analyzed the effect of these ... -
“Sustainability is not a vegan coffee shop.” Eliciting citizen attitudes and perspectives to localize the UN sustainable development goals
(Journal article; Peer reviewed, 2023)Integrating the United Nations Sustainable Development Goals (SDGs) into national legislation includes a need for their localization. The authors posit that this concept of localizing the SDGs is achieved if the goals are ... -
Oceanographic connectivity explains the intra-specific diversity of mangrove forests at global scales
(Journal article; Peer reviewed, 2023)The distribution of mangrove intra-specific biodiversity can be structured by historical demographic processes that enhance or limit effective population sizes. Oceanographic connectivity (OC) may further structure ... -
Repeated exposure affects susceptibility and responses of Atlantic salmon (Salmo salar) towards the ectoparasitic salmon lice (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2023)Atlantic salmon (Salmo salar) is repeatedly exposed to and infected with ectoparasitic salmon lice (Lepeophtheirus salmonis) both in farms and in nature. However, this is not reflected in laboratory experiments where fish ... -
Shallow and deep groundwater moderate methane dynamics in a high Arctic glacial catchment
(Journal article; Peer reviewed, 2024)Glacial groundwater can mobilize deep-seated methane from beneath glaciers and permafrost in the Arctic, leading to atmospheric emissions of this greenhouse gas. We present a temporal, hydro-chemical dataset of methane-rich ... -
Functional specialization of Aurora kinase homologs during oogenic meiosis in the tunicate Oikopleura dioica
(Journal article; Peer reviewed, 2023)A single Aurora kinase found in non-vertebrate deuterostomes is assumed to represent the ancestor of vertebrate Auroras A/B/C. However, the tunicate Oikopleura dioica, a member of the sister group to vertebrates, possesses ... -
Exploring the effects of acute stress exposure on lumpfish plasma and liver biomarkers
(Journal article; Peer reviewed, 2023-11-23)This study aimed to expand knowledge on lumpfish stress physiology by investigating the effects of acute stress on primary (i.e., cortisol) and secondary (e.g., metabolites) stress responses, as well as oxidative stress ... -
Nature's View of Ionotropic Glutamate Receptors
