Persist in place or shift in space? Evaluating the adaptive capacity of species to climate change
(Journal article; Peer reviewed, 2020)Assessing the vulnerability of species to climate change serves as the basis for climate-adaptation planning and climate-smart conservation, and typically involves an evaluation of exposure, sensitivity, and adaptive ... -
Rock sponges (lithistid Demospongiae) of the Northeast Atlantic seamounts, with description of ten new species
(Journal article; Peer reviewed, 2020)Background Lithistid demosponges, also known as rock sponges, are a polyphyletic group of sponges which are widely distributed. In the Northeast Atlantic (NEA), 17 species are known and the current knowledge on their ... -
Seasonal Variability in Near-bed Environmental Conditions in the Vazella pourtalesii Glass Sponge Grounds of the Scotian Shelf
(Journal article; Peer reviewed, 2021)The Scotian Shelf harbors unique aggregations of the glass sponge Vazella pourtalesii that provides an important habitat for benthic and pelagic fauna. Recent studies have shown that these sponge grounds have persisted in ... -
How trophic cascades and photic zone nutrient content interact to generate basin-scale differences in the microbial food web
(Journal article; Peer reviewed, 2020)In linear food chains, resource and predator control produce positive and negative correlations, respectively, between biomass at adjacent trophic levels. These simple relationships become more complex in food webs that ... -
Reproductive Biology of Geodia Species (Porifera, Tetractinellida) From Boreo-Arctic North-Atlantic Deep-Sea Sponge Grounds
(Journal article; Peer reviewed, 2020)Boreo-arctic sponge grounds are essential deep-sea structural habitats that provide important services for the ecosystem. These large sponge aggregations are dominated by demosponges of the genus Geodia (order Tetractinellida, ... -
Centennial relationships between ocean temperature and Atlantic puffin production reveal shifting decennial trends
(Journal article; Peer reviewed, 2021)The current warming of the oceans has been shown to have detrimental effects for a number of species. An understanding of the underlying mechanisms may be hampered by the non-linearity and non-stationarity of the relationships ... -
The synergistic interaction of thermal stress coupled with overstocking strongly modulates the transcriptomic activity and immune capacity of rainbow trout (Oncorhynchus mykiss)
(Journal article; Peer reviewed, 2020)The objective of the present study is to identify and evaluate informative indicators for the welfare of rainbow trout exposed to (A) a water temperature of 27 °C and (B) a stocking density of 100 kg/m3 combined with a ... -
Transcriptome responses in polar cod (Boreogadus saida) liver slice culture exposed to benzo[a]pyrene and ethynylestradiol: insights into anti-estrogenic effects
(Journal article; Peer reviewed, 2021)Polar cod (Boreogadus saida) is a key species in the arctic marine ecosystem vulnerable to effects of pollution, particularly from petroleum related activities. To facilitate studying the effects of those pollutants, we ... -
Secchi disk measurements in turbid water
(Journal article; Peer reviewed, 2020)In the classical theory of the Secchi disk depth, diffuse sunlight falling on the disk is reflected back to the observer's eye along the most direct route, as a beam. The disappearance depth, ZSD, of the disk is then ... -
What Is Gill Health and What Is Its Role in Marine Finfish Aquaculture in the Face of a Changing Climate?
(Journal article; Peer reviewed, 2020)It is hard to find a definition of gill health in the literature although there is a lot of information on changes to gill structure as a result of infectious and non-infectious challenge. How these changes relate to overall ... -
Sequence analysis and spatiotemporal developmental distribution of the Cat-1-type transporter slc7a1a in zebrafish (Danio rerio)
(Journal article; Peer reviewed, 2020)Cationic amino acid transporter 1 (Cat-1 alias Slc7a1) is a Na+-independent carrier system involved in transport and absorption of the cationic amino acids lysine, arginine, histidine, and ornithine and has also been shown ... -
Thermal transgenerational effects remain after two generations
(Journal article; Peer reviewed, 2020)Transgenerational plasticity (TGP) is increasingly recognized as a mechanism by which organisms can respond to environments that change across generations. Although recent empirical and theoretical studies have explored ... -
Method for cryopreservation of Paramoeba perurans
(Journal article; Peer reviewed, 2020-11-07)Paramoeba perurans causes amoebic gill disease (AGD), which is a major problem in aquaculture worldwide. The parasite can be cultured in vitro, but to this date, no method for long-term storage of the clones exists. In ... -
Genetically similar temperate phages form coalitions with their shared host that lead to niche-specific fitness effects.
(Journal article; Peer reviewed, 2020-04-02)Temperate phages engage in long-term associations with their hosts that may lead to mutually beneficial interactions, of which the full extent is presently unknown. Here, we describe an environmentally relevant model system ... -
Nutrient Digestibility, Growth, Mucosal Barrier Status, and Activity of Leucocytes From Head Kidney of Atlantic Salmon Fed Marine- or Plant-Derived Protein and Lipid Sources
(Journal article; Peer reviewed, 2021-02-19)Nutrient digestibility, growth, and mucosal barrier status of fish skin, gills, and distal intestine were studied in Atlantic salmon fed feeds based on marine or plant-derived ingredients. The barrier status was assessed ... -
Decision-making from the animal perspective: Bridging ecology and subjective cognition
(Journal article; Peer reviewed, 2019-05-14)Organisms have evolved to trade priorities across various needs, such as growth, survival, and reproduction. In naturally complex environments this incurs high computational costs. Models exist for several types of decisions, ... -
Me, myself and I -Teachers’ self-motivation and sense of responsibility determine the use of active learning methods
(Journal article; Peer reviewed, 2019)Extended use of laboratory and field courses makes biology a discipline considering itself as a habitual practitioner of active learning strategies. We investigated how widely the faculty at the Department of Biological ... -
An interdisciplinary, student-active course on UN Sustainable Development Goal 14: Life below water
(Journal article; Peer reviewed, 2021)Educating student to respond to Sustainable Development Goals (SDGs) calls for teaching and learning where students are at the centre of their own learning. Sustainability questions are ‘wicked problems’, where no single, ... -
Joining forces for sustainability education – Sustainability Education Collective at the University of Bergen
(Journal article; Peer reviewed, 2021)Agenda 2030 and its Sustainable Development Goals (SDGs) have resulted in a heightened focus on sustainability in Norwegian – and global – academia. Sustainability Education requires innovative pedagogy and active, ... -
Holocene fire and vegetation dynamics in the Central Pyrenees (Spain)
(Journal article; Peer reviewed, 2020)Fire-vegetation relationships are critical to understand transient mountain ecosystems and their long-term landscape dynamics, which is essential for alpine forest conservation. In this paper we aim to (1) reconstruct the ...
