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, ... -
Reproductive investment in Atlantic cod off Newfoundland: Contrasting trends between males and females
(Peer reviewed; Journal article, 2017-08-31)Life history theory predicts selection for higher reproductive investment in response to increased mortality among mature individuals. We tested this prediction over the period from 1978 to 2013 for three populations of ... -
Reproductive traits across the Atlantic herring (Clupea harengus L.) stock complex
(Doctoral thesis, 2017-06-08)Herring (Clupea harengus and C. pallasii) have an important socio-economic role worldwide and consist of diverse populations. These populations are distributed throughout both the North Atlantic and North Pacific Oceans. ... -
Resilience to exogenous shocks in environmental management regimes in the Arctic – lessons learned from survivors
(Peer reviewed; Journal article, 2019-06-13)A changing climate will impact not only the environment but all levels of governance thereof, including the context of the close to 400 multilateral environmental management agreements signed since the year 2000. For the ... -
Resolving the zinc binding capacity of honey bee vitellogenin and locating its putative binding sites
(Journal article; Peer reviewed, 2022)The protein vitellogenin (Vg) plays a central role in lipid transportation in most egg-laying animals. High Vg levels correlate with stress resistance and lifespan potential in honey bees (Apis mellifera). Vg is the primary ... -
Resource allocation in two selected Carex species along climate gradients
(Master thesis, 2010-11-22)Climate will change and is already changing and all organisms are going to react to it, as it is a limiting factor to their lives. To be able to have an idea how plants might respond to climate change, it is important to ... -
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 ... -
Respiratory burst assay for leukocytter fra Atlantisk laks (Salmo salar L.) og Atlantisk torsk (Gadus morhua L.)
(Master thesis, 2009-06-22)Fagocytose er en viktig funksjon i det uspesifikke immunforsvaret hos fisk, og medvirker til at leukocytter kan drepe infiserende patogener. Leukocytters evne til å ta opp, drepe og bryte ned fagocytterte patogener, er ... -
The response of a boreal deep-sea sponge holobiont to acute thermal stress
(Peer reviewed; Journal article, 2017-05-22)Effects of elevated seawater temperatures on deep-water benthos has been poorly studied, despite reports of increased seawater temperature (up to 4 °C over 24 hrs) coinciding with mass mortality events of the sponge Geodia ... -
The Response of Heterotrophic Prokaryote and Viral Communities to Labile Organic Carbon Inputs Is Controlled by the Predator Food Chain Structure
(Peer reviewed; Journal article, 2017-08-23)Factors controlling the community composition of marine heterotrophic prokaryotes include organic-C, mineral nutrients, predation, and viral lysis. Two mesocosm experiments, performed at an Arctic location and bottom-up ... -
Response of Methanogens in Arctic Sediments to Temperature and Methanogenic Substrate Availability
(Peer reviewed; Journal article, 2015-06-17)Although cold environments are major contributors to global biogeochemical cycles, comparatively little is known about their microbial community function, structure, and limits of activity. In this study a microcosm based ... -
Response to comment on “Dispersal limitations matter for microbial morphospecies”
(Peer reviewed; Journal article, 2007)Pither argues that the relationship we found between regional species-richness maxima and modal lake-pH is expected because both values are constrained by the regional pH range and therefore cannot be interpreted as a ... -
Response: Demography affects spawning location in Northeast Arctic cod, but what affects demography?
(Journal article, 2015-06-19) -
Responses of Free-Living Planktonic Bacterial Communities to Experimental Acidification and Warming
(Journal article; Peer reviewed, 2023)Climate change driven by human activities encompasses the increase in atmospheric CO2 concentration and sea-surface temperature. Little is known regarding the synergistic effects of these phenomena on bacterial communities ... -
Responses of tundra plants to experimental warming : meta-analysis of the international tundra experiment
(Peer reviewed; Journal article, 1999)The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using a common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ... -
Resurrection of genus Phocanema Myers, 1959, as a genus independent from Pseudoterranova Mozgovoĭ, 1953, for nematode species (Anisakidae) parasitic in pinnipeds and cetaceans, respectively
(Journal article; Peer reviewed, 2023)Species of the genus Pseudoterranova, infect kogiid cetaceans and pinnipeds. However, there is mounting molecular evidence that those from cetaceans and pinnipeds are not congeneric. Here, we provide further evidence of ... -
Reversals in Temperature-Precipitation Correlations in the Northern Hemisphere Extratropics During the Holocene
(Journal article; Peer reviewed, 2022)Future precipitation levels remain uncertain because climate models have struggled to reproduce observed variations in temperature-precipitation correlations. Our analyses of Holocene proxy-based temperature-precipitation ... -
Reversible mutations in gliding motility and virulence genes: A flexible and efficient phage defence mechanism in Flavobacterium psychrophilum
(Journal article; Peer reviewed, 2022)Flavobacteria are among the most important pathogens in freshwater salmonid aquaculture worldwide. Due to concerns regarding development of antibiotic resistance, phage therapy has been proposed as a solution to decrease ... -
Review and test of reproducibility of subdecadal resolution palaeoenvironmental reconstructions from microfossil assemblages
(Peer reviewed; Journal article, 2019)Very high, even annual, resolution quantitative palaeoenvironmental reconstructions have been generated from microfossil assemblage data using transfer functions. Evidence of the utility of some of these reconstructions ... -
Review of ecosystem models of fjords; new insights of relevance to fisheries management
(Peer reviewed; Journal article, 2001)Fjords on the west coast of Norway contain small ecosystems that have similar physical and biological processes as large oceanic ecosystems. Hence, they are ideal experimental facilities. However, ecosystems are complex ...
