Aquaporin splice variation differentially modulates channel function during marine teleost egg hydration
(Journal article; Peer reviewed, 2023)Aquaporin-mediated oocyte hydration is a developmentally regulated adaptive mechanism that co-occurs with meiosis resumption in marine teleosts. It provides the early embryos with vital water until osmoregulatory systems ... -
Are synchronous chats a silver lining of emergency remote instruction? Text-based chatting is disproportionately favored by women in a non-majors introductory biology course
(Journal article; Peer reviewed, 2022)The coronavirus disease 2019 (COVID-19) pandemic has led to a reimagining of many aspects of higher education, including how instructors interact with their students and how they encourage student participation. Text-based ... -
Assessing the effectiveness of an electricalstunning and chilling protocol for theslaughter of Atlantic mackerel (Scomber scombrus)
(Peer reviewed; Journal article, 2019-09-04)Inducing unconsciousness in fish using electrical stunning prior to slaughter may improve fish welfare and fillet quality if such practises can be disseminated into wild capture fisheries. The objectives of this study were ... -
Assessing the reproductive biology of the Greenland shark (Somniosus microcephalus)
(Journal article; Peer reviewed, 2020)The Greenland shark (Somniosus microcephalus, Squaliformes: Somniosidae) is a long-lived Arctic top predator, which in combination with the high historical and modern fishing pressures, has made it subject to increased ... -
Behavioural economics in fisheries: A systematic review protocol
(Journal article; Peer reviewed, 2021)Background The field of behavioural economics holds several opportunities for integrated fisheries management and conservation and can help researchers and managers alike understand fisher behaviour and decision-making. ... -
Close to open—Factors that hinder and promote open science in ecology research and education
(Journal article; Peer reviewed, 2022-12-21)The Open Science (OS) movement is rapidly gaining traction among policy-makers, research funders, scientific journals and individual scientists. Despite these tendencies, the pace of implementing OS throughout the scientific ... -
Differences in metabolic rate between two Atlantic cod (Gadus morhua) populations estimated with carbon isotopic composition in otoliths
(Journal article; Peer reviewed, 2021)The isotopic composition of inorganic carbon in otoliths (δ13Coto) can be a useful tracer of metabolic rates and a method to study ecophysiology in wild fish. We evaluated environmental and physiological sources of δ13Coto ... -
Effects of chitin synthesis inhibitor treatment on Lepeophtheirus salmonis (Copepoda, Caligidae) larvae
(Peer reviewed; Journal article, 2019-09-23)The salmon louse (Lepeophtheirus salmonis) is an ectoparasite infecting Atlantic salmon (Salmo salar), which causes substantial problems to the salmon aquaculture and threatens wild salmon. Chitin synthesis inhibitors ... -
A framework for the development of a global standardised marine taxon reference image database (SMarTaR-ID) to support image-based analyses
(Peer reviewed; Journal article, 2019-12-31)Video and image data are regularly used in the field of benthic ecology to document biodiversity. However, their use is subject to a number of challenges, principally the identification of taxa within the images without ... -
The FTZ-F1 gene encodes two functionally distinct nuclear receptor isoforms in the ectoparasitic copepod salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2021)The salmon louse, Lepeophtheirus salmonis, is an ectoparasitic crustacean that annually inflicts substantial losses to the aquaculture industry in the northern hemisphere and poses a threat to the wild populations of ... -
Genome-wide SNP analyses reveal population structure of Portunus pelagicus alongVietnam coastline
(Peer reviewed; Journal article, 2019-11-05)The blue swimming crab (Portunus pelagicus Linnaeus, 1758) is one of the commercially exploited crab fishery resources in Vietnam. This is the first study to provide a broad survey of genetic diversity, population structure ... -
Identification and characterization of a hyperthermophilic GH9 cellulase from the Arctic Mid-Ocean Ridge vent field
(Peer reviewed; Journal article, 2019-09-06)A novel GH9 cellulase (AMOR_GH9A) was discovered by sequence-based mining of a unique metagenomic dataset collected at the Jan Mayen hydrothermal vent field. AMOR_GH9A comprises a signal peptide, a catalytic domain and a ... -
Life histories of Antarctic incirrate octopods (Cephalopoda: Octopoda)
(Journal article; Peer reviewed, 2019-07-11)As a general trend in the life history of marine organisms, species inhabiting cold waters have reduced growth rates and increased lifespans. Studies based on egg sizes and brooding times of deep-sea and polar octopods ... -
Molecular evidence of parallel evolution in a cyanophage
(Journal article; Peer reviewed, 2023)Antagonistic interactions between bacteriophage (phage) and its bacterial host drives the continual selection for resistance and counter-defence. To date, much remains unknown about the genomic evolution that occurs as ... -
Multilocus sequence analysis reveals different lineages of Pseudomonas anguilliseptica associated with disease in farmed lumpfish (Cyclopterus lumpus L.)
(Journal article; Peer reviewed, 2021)The bacterium Pseudomonas anguilliseptica has in recent years emerged as a serious threat to production of lumpfish in Norway. Little is known about the population structure of this bacterium despite its association with ... -
Neural activation in photosensitive brain regions of Atlantic salmon (Salmo salar) after light stimulation
(Journal article; Peer reviewed, 2021)Photoreceptive inputs to the teleost brain are perceived as image of the visual world and as photo-modulation of neuroendocrine and neuronal signals. The retina and pineal organ are major receptive organs with projections ... -
