A novel role for pigment genes in the stress response in rainbow trout (Oncorhynchus mykiss)
(Journal article; Peer reviewed, 2016)In many vertebrate species visible melanin-based pigmentation patterns correlate with high stress- and disease-resistance, but proximate mechanisms for this trait association remain enigmatic. Here we show that a missense ... -
A snap shot of the short-term response of crustaceans to macrophyte detritus in the deep Oslofjord
(Journal article; Peer reviewed, 2016)A test deployment of a time-lapse camera lander in the deep Oslofjord (431 m) was used to obtain initial information on the response of benthic fauna to macroalgal debris. Three macroalgal species were used on the lander ... -
Atmospheric mercury inputs in montane soils increase with elevation: evidence from mercury isotope signatures
(Journal article; Peer reviewed, 2013)The influence of topography on the biogeochemical cycle of mercury (Hg) has received relatively little attention. Here, we report the measurement of Hg species and their corresponding isotope composition in soil sampled ... -
Bioaccumulation and biological effects of cigarette litter in marine worms
(Journal article; Peer reviewed, 2015)Marine debris is a global environmental issue. Smoked cigarette filters are the predominant coastal litter item; 4.5 trillion are littered annually, presenting a source of bioplastic microfibres (cellulose acetate) and ... -
Chloropicophyceae, a new class of picophytoplanktonic prasinophytes
(Journal article; Peer reviewed, 2017)Prasinophytes are a paraphyletic group of nine lineages of green microalgae that are currently classified either at the class or order level or as clades without formal taxonomic description. Prasinophyte clade VII comprises ... -
Early life stress induces long-term changes in limbic areas of a teleost fish: The role of catecholamine systems in stress coping
(Journal article; Peer reviewed, 2018)Early life stress (ELS) shapes the way individuals cope with future situations. Animals use cognitive flexibility to cope with their ever-changing environment and this is mainly processed in forebrain areas. We investigated ... -
Efficient coralline algal psbA mini barcoding and High Resolution Melt (HRM) analysis using a simple custom DNA preparation
(Journal article; Peer reviewed, 2019)Coralline algae form extensive maerl and rhodolith habitats that support a rich biodiversity. Calcium carbonate harvesting as well as trawling activities threatens this ecosystem. Eleven species were recorded so far as ... -
Empirical support for sequential imprinting during downstream migration in Atlantic salmon (Salmo salar) smolts
(Peer reviewed; Journal article, 2022)The precise homing of Atlantic salmon to their natal river and spawning grounds is the foundation for locally adapted genetically differentiated populations across rivers or across river sections. A sequential imprinting ... -
Fine-scale behavioural differences distinguish resource use by ecomorphs in a closed ecosystem
(Journal article; Peer reviewed, 2016)Temporal differences in habitat use and foraging specialisms between ecomorphs represent aspects of behavioural phenotype that are poorly understood with regard to the origin and maintenance of ecological diversity. We ... -
Grazers extend blue carbon transfer by slowing sinking speeds of kelp detritus
(Journal article; Peer reviewed, 2018)Marine plant communities such as kelp forests produce significant amounts of detritus, most of which is exported to areas where it can constitute an important trophic subsidy or potentially be sequestered in marine sediments. ... -
Hydropower-induced selection of behavioural traits in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Renewable energy projects such as hydropower facilities contribute towards meeting the world`s growing energy demands and urgent need for mitigating climate change. However, such infrastructure has the potential to ... -
Impact of environmental factors on aquatic biodiversity in roadside stormwater ponds
(Journal article; Peer reviewed, 2019)Constructed stormwater ponds mitigate runoff volumes and pollution, and provide other ecosystem services, such as supporting biodiversity, but these services attracted relatively less attention. The impacts of the pollution ... -
Increased levels of the oxidative stress biomarker 8-iso-prostaglandin F2α in wastewater associated with tobacco use
(Journal article; Peer reviewed, 2016)Wastewater analysis has been demonstrated to be a complementary approach for assessing the overall patterns of drug use by a population while the full potential of wastewater-based epidemiology has yet to be explored. ... -
The influence of hydrodynamic exposure on carbon storage and nutrient retention in eelgrass (Zostera marina L.) meadows on the Swedish Skagerrak coast
(Journal article; Peer reviewed, 2020)Cold-temperate seagrass (Zostera marina) meadows provide several important ecosystem services, including trapping and storage of sedimentary organic carbon and nutrients. However, seagrass meadows are rapidly decreasing ... -
Lipid metabolism in Calanus finmarchicus is sensitive to variations in predation risk and food availability
(Peer reviewed; Journal article, 2020)Late developmental stages of the marine copepods in the genus Calanus can spend extended periods in a dormant stage (diapause) that is preceded by the accumulation of large lipid stores. We assessed how lipid metabolism ... -
Nitrate respiration occurs throughout the depth of mucoid and non-mucoid Pseudomonas aeruginosa submerged agar colony biofilms including the oxic zone
(Peer reviewed; Journal article, 2022)Pseudomonas aeruginosa is an opportunistic pathogen and well characterized biofilm former. P. aeruginosa forms strong oxygen gradients inside biofilms due to rapid oxygen respiration in the top layers and the poor solubility ... -
No additional stress of sublethal gas supersaturation in a landlocked population of Atlantic salmon (Salmo salar) exposed to environmental acidification
(Peer reviewed; Journal article, 2024)The landlocked Atlantic salmon population “bleke” faces extinction due to environmental acidification (EA) and hydropower expansion in the Norwegian river Otra. Despite of restoration, unexpected mortality has been reported ... -
Organic nitrogen steadily increasing in Norwegian rivers draining to the Skagerrak coast
(Peer reviewed; Journal article, 2020)Declining atmospheric nitrogen (N) deposition, through reduction in the direct input of inorganic N, may result in less inorganic N being leached from soils to freshwaters (dissolved inorganic N = DIN). Declining sulphur ... -
Passive sampling and benchmarking to rank HOC levels in the aquatic environment
(Peer reviewed; Journal article, 2021)The identification and prioritisation of water bodies presenting elevated levels of anthropogenic chemicals is a key aspect of environmental monitoring programmes. Albeit this is challenging owing to geographical scales, ... -
Polycyclic aromatic hydrocarbons: bioaccumulation in dragonfly nymphs (Anisoptera), and determination of alkylated forms in sediment for an improved environmental assessment
(Peer reviewed; Journal article, 2020)Road runoff carries a mixture of contaminants that threatens the quality of natural water bodies and the health of aquatic organisms. The use of sedimentation ponds is a nature-based solution for the treatment of road ...
