Caligus elongatus and other sea lice of the genus Caligus as parasites of farmed salmonids: A review
(Journal article; Peer reviewed, 2020)This review was prompted by reports of unusually large numbers of sea lice tentatively identified as Caligus elongatus infesting farmed salmon in northern Norway. Following a brief introduction to the sea lice problem in ... -
Ontogenetic movements of cod in Arctic fjords and the Barents Sea as revealed by otolith microchemistry
(Journal article; Peer reviewed, 2020-04-06)The distribution of Atlantic cod (Gadus morhua) in northern Norwegian waters is expanding eastward and northward in the Barents Sea and along western Svalbard. In the Arctic fjords of Svalbard, cod has become abundant, but ... -
Sequence-based enzyme discovery from marine microbial diversity : Multiple approaches for the heterologous expression of genes in Escherichia coli
(Doctoral thesis, 2021-06-09)The vast biodiversity of marine environments is increasingly being recognized as a source for new enzymes with value in both basic research and applications within biotechnology. In this project, the major aim was to ... -
Marine Plastics from Norwegian West Coast Carry Potentially Virulent Fish Pathogens and Opportunistic Human Pathogens Harboring New Variants of Antibiotic Resistance Genes
(Journal article; Peer reviewed, 2020)To our best knowledge this is the first study characterizing fish pathogens isolated from marine plastics from the West coast of Norway for their potential for pathogenicity using whole genome sequencing. Marine plastic ... -
Nutrient and chemical contaminant levels in five marine fish species from Angola—The EAF-Nansen programme
(Journal article; Peer reviewed, 2020)Fish is a rich source of several important nutrients and an important part of the otherwise plant-dominated diet present in Angola. However, fish may also be a source of contaminants. The aim of this study was to analyse ... -
Testing macroecological abundance patterns: The relationship between local abundance and range size, range position and climatic suitability among European vascular plants
(Journal article; Peer reviewed, 2020)Aim A fundamental question in macroecology centres around understanding the relationship between species’ local abundance and their distribution in geographical and climatic space (i.e. the multi-dimensional climatic space ... -
Biotic rescaling reveals importance of species interactions for variation in biodiversity responses to climate change
(Journal article; Peer reviewed, 2020)Generality in understanding biodiversity responses to climate change has been hampered by substantial variation in the rates and even directions of response to a given change in climate. We propose that such context ... -
Cholesterol-containing lipid nanodiscs promote an α-synuclein binding mode that accelerates oligomerization
(Journal article; Peer reviewed, 2021)Dysregulation of the biosynthesis of cholesterol and other lipids has been implicated in many neurological diseases, including Parkinson's disease. Misfolding of α-synuclein (α-Syn), the main actor in Parkinson's disease, ... -
Strengthening the evidence base for temperature-mediated phenological asynchrony and its impacts
(Journal article; Peer reviewed, 2021)Climate warming has caused the seasonal timing of many components of ecological food chains to advance. In the context of trophic interactions, the match–mismatch hypothesis postulates that differential shifts can lead to ... -
A 24,000-year ancient DNA and pollen record from the Polar Urals reveals temporal dynamics of arctic and boreal plant communities
(Journal article; Peer reviewed, 2020)A 24,000-year record of plant community dynamics, based on pollen and ancient DNA from the sediments (sedaDNA) of Lake Bolshoye Shchuchye in the Polar Ural Mountains, provides detailed information on the flora of the Last ... -
Last Glacial Maximum environmental conditions at Andøya, northern Norway; evidence for a northern ice-edge ecological “hotspot”
(Journal article; Peer reviewed, 2020)Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local ... -
Identification and characterization of the Atlantic salmon peptide transporter 1a
(Journal article; Peer reviewed, 2020)Peptide transporter 1 (PepT1) mediates the uptake of dietary di-/tripeptides in vertebrates. However, in teleost fish gut, more than one PepT1-type transporter might operate, because of teleost-specific whole gen(om)e ... -
A New Species of Osedax (Siboglinidae: Annelida) From Colonization Experiments in the Arctic Deep Sea
(Journal article; Peer reviewed, 2020)Large parcels of organic matter in the deep sea, such as whale carcasses, harbor a very specialized fauna, most famously the bone-eating worms in the genus Osedax (Annelida, Siboglinidae). Although Osedax was first described ... -
Trade-off between mate choice speed and decision accuracy under mating competition in female sand gobies
(Journal article; Peer reviewed, 2020)Variation in female mating performance can affect the direction and rate of evolution through sexual selection. The social environment determines the availability of mates and the competitive situation, and hence can ... -
Respiration rates of herring larvae at different salinities and effects of previous environmental history
(Journal article; Peer reviewed, 2020)Metabolic rates of early life history stages of marine fishes show considerable inter-individual differences and are highly influenced by extrinsic factors like temperature or food availability. Measuring oxygen uptake ... -
On giant shoulders: how a seamount affects the microbialcommunity composition of seawater and sponges
(Journal article; Peer reviewed, 2020)Seamounts represent ideal systems to study the influence and interdependency of environmental gradients at a single geographic location. These topographic features represent a prominent habitat for various forms of life, ... -
Comprehensive characterization of glial cells in the urochordate Ciona intestinalis
(Doctoral thesis, 2021-05-31)There are two main classes of cells that are present in the nervous system: neurons and glia. Neurons are the signalling units of the nervous system and are responsible to transmit electrical and chemical signals to other ... -
Plant traits and vegetation data from climate warming experiments along an 1100 m elevation gradient in Gongga Mountains, China
(Journal article; Peer reviewed, 2020)Functional trait data enhance climate change research by linking climate change, biodiversity response, and ecosystem functioning, and by enabling comparison between systems sharing few taxa. Across four sites along a ... -
Forest fragmentation modifes the composition of bumblebee communities and modulates their trophic and competitive interactions for pollination
(Journal article; Peer reviewed, 2020)Understanding the effects of landscape fragmentation on global bumblebee declines requires going beyond estimates of abundance and richness and evaluating changes in community composition and trophic and competitive ...
