Inequal responses of drylands to radiative forcing geoengineering methods
(Peer reviewed; Journal article, 2019)Climate geoengineering has the potential to reduce global warming. However, the nonlinear responses of Earth's large‐scale circulation to climate geoengineering can exacerbate regional climate change, with potential ... -
Performance of post-processed methods in hydrological predictions evaluated by deterministic and probabilistic criteria
(Peer reviewed; Journal article, 2019)Meteorological Ensemble Streamflow Prediction (ESP), which uses Ensemble Weather forecasts (EWFs) to drive hydrological models, is a useful methodology for extending forecast periods and to provide valuable uncertainty ... -
Consistent fluctuations in intermediate water temperature off the coast of Greenland and Norway during Dansgaard-Oeschger events
(Peer reviewed; Journal article, 2019)Rapid warmings epitomize the Dansgaard-Oeschger events that are recorded in Greenland ice cores and imprinted in ocean sediment cores. While the abrupt climate changes appear connected to perturbations in sea ice and ocean ... -
Application of Clumped Isotope Thermometry to Benthic Foraminifera
(Peer reviewed; Journal article, 2019)Obtaining absolute temperatures of the ocean in deep time is complicated by the lack of constraints on seawater chemistry. Seawater salinity, carbonate ion concentration, δ18O, and elemental abundance changes may obscure ... -
Spatial patterns of arctic sponge ground fauna and demersal fish are detectable in autonomous underwater vehicle (AUV) imagery
(Peer reviewed; Journal article, 2019)Deep-sea sponge grounds are important habitats that provide several ecosystem services, yet relatively little is known about their distribution and ecology. While most surveys have focused on the broad-scale distribution ... -
Deep-Sea Carnivorous Sponges From the Mariana Islands
(Peer reviewed; Journal article, 2019)Carnivorous sponges belonging to family Cladorhizidae (Porifera, Demospongiae, Poecilosclerida) are unique within phylum Porifera due to their ability to capture and envelop small prey. While other sponges use an aquiferous ... -
Molecular and physiological responses to long-term carbon dioxide exposure in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2019)Optimal water quality is vital for the growth of Atlantic salmon aquaculture production. Recent data showed that Atlantic salmon feed intake and growth reduce linearly with increasing water carbon dioxide (CO2) concentrations, ... -
New ecosystems in the deep subsurface follow the flow of water driven by geological activity
(Peer reviewed; Journal article, 2019)Eukarya have been discovered in the deep subsurface at several locations in South Africa, but how organisms reach the subsurface remains unknown. We studied river-subsurface fissure water systems and identified Eukarya ... -
Effects of an aquaculture pesticide (diflubenzuron) on non-target shrimp populations: Extrapolation from laboratory experiments to the risk of population decline
(Peer reviewed; Journal article, 2019)Marine aquaculture production has lately experienced high economic growth, but also concerns related to production and environmental contamination. For the Atlantic salmon aquaculture industry, the ectoparasitic crustacean ... -
Can structural enrichment reduce predation mortality and increase recaptures of hatchery‐reared Atlantic salmon Salmo salar L. fry released into the wild?
(Peer reviewed; Journal article, 2019)Captive‐reared fish often have poor survival in the wild and may fail to boost threatened populations. Enrichment during the nursery period can in some circumstances generate a broader behavioural repertoire than conventional ... -
Phylogenetic Reclassification of Vertebrate Melatonin Receptors To Include Mel1d
(Peer reviewed; Journal article, 2019)The circadian and seasonal actions of melatonin are mediated by high affinity G-protein coupled receptors (melatonin receptors, MTRs), classified into phylogenetically distinct subtypes based on sequence divergence and ... -
Effects of temperature and photoperiod on rainbow trout (Oncorhynchus mykiss) smoltification and haematopoiesis
(Peer reviewed; Journal article, 2019)Highlights • nkaα1a, nkaα1b and nkcc1a provide relevant information that the NKA activity does not reflect. • While nkaα1a and nkcc1a transcription are mainly regulated by temperature, nkaα1b is regulated mainly by ... -
Swimming with the fishes: validating drift diving to identify farmed Atlantic salmon escapees in the wild
(Peer reviewed; Journal article, 2019)Escaped farmed Atlantic salmon Salmo salar interbreeding with wild conspecifics represents a threat to the genetic integrity and viability of wild populations. Therefore, it is necessary to accurately quantify escapees in ... -
A test of migratory coupling in the salmon-trout predator-prey complex of a subarctic fjord
(Peer reviewed; Journal article, 2019)Atlantic salmon (Salmo salar) smolts are vulnerable to predators during their seaward migration. To determine whether sea trout (Salmo trutta) exhibit a coupled migration to exploit the smolt run, we tracked Atlantic salmon ... -
Multi-decadal warming of Atlantic water and associated decline of dissolved oxygen in a deep fjord
(Peer reviewed; Journal article, 2019)Previous studies have shown decline in dissolved oxygen of the ocean basins. A hypothesis for this development is that ocean warming through increased stratification has caused reduced ventilation of the interior ocean. ... -
The crystal structure of haemoglobin from Atlantic cod
(Peer reviewed; Journal article, 2019)The crystal structure of haemoglobin from Atlantic cod has been solved to 2.54 A˚ resolution. The structure consists of two tetramers in the crystallographic asymmetric unit. The structure of haemoglobin obtained from one ... -
The risk of individual fish being captured multiple times in a catch and release fishery
(Peer reviewed; Journal article, 2019)The proportion of angled Atlantic salmon Salmo salar L. being caught and released has increased. If individuals are repeatedly captured, this may have fish welfare consequences. Of 995 Atlantic salmon tagged during catch ... -
Tracking Holocene palaeostratification and productivity changes in the Western Irish Sea: A multi-proxy record
(Peer reviewed; Journal article, 2019)The Western Irish Sea preserves an exceptionally thick (ca. 40 m) Holocene succession that is ideally suited to understanding the pattern of palaeostratification and water mass productivity changes in the region, and their ... -
Insights into the potential of the Atlantic cod gut microbiome as biomarker of oil contamination in the marine environment
(Peer reviewed; Journal article, 2019)Background: Microorganisms are widespread in all environments, including in and on animal bodies. The gut microbiome has an essential influence on fish health, and is affected by several persistent and harmful organic and ... -
Fatigue in primary Sjögren's syndrome: A proteomic pilot study of cerebrospinal fluid
(Peer reviewed; Journal article, 2019)Objectives: Fatigue is a frequent and often disabling phenomenon that occurs in patients with chronic inflammatory and immunological diseases, and the underlying biological mechanisms are largely unknown. Because fatigue ...
