Vital rates in early life history underlie shifts in biotic interactions along bioclimatic gradients: An experimental test of the Stress Gradient Hypothesis
(Journal article; Peer reviewed, 2021)Question The Stress Gradient Hypothesis (SGH) predicts that competition and facilitation shift along stress gradients. We ask if the underlying mechanisms operate at specific points in plant life history, and if patterns ... -
Voices of young biosphere stewards on the strengths, weaknesses, and ways forward for 74 UNESCO Biosphere Reserves across 83 countries
(Journal article; Peer reviewed, 2021)Young stakeholders are key actors in social-ecological systems, who have the capacity to be agents of sustainability transformation but are also at high risk of exclusion in the unfolding of global change challenges. Despite ... -
Vurdering av lakselusindusert villfiskdødelighet per produksjonsområde i 2016 og 2017
(Research report, 2017)Ekspertgruppen ble i mars 2017 oppnevnt for ett år for å foreta en vurdering av lakselusindusert dødelighet på villfisk i 13 produksjonsområder i Norge. En foreløpig rapport basert på data fra 2016 ble levert i april 2017 ... -
Vurderingspreferanser hos studenter i høyere utdanning
(Master thesis, 2023-06-02)I denne studien belyses vurderingspreferansene til kvinnelige, nye og førstegenerasjons-studenter, da forskning viser at de forlater STEM i større grad enn andre studenter. En av pådriverne er «high stakes» vurderinger, ... -
Warming, drought, and disturbances lead to shifts in functional composition: A millennial-scale analysis for Amazonian and Andean sites
(Journal article; Peer reviewed, 2023)Tropical forests are changing in composition and productivity, probably in response to changes in climate and disturbances. The responses to these multiple environmental drivers, and the mechanisms underlying the changes, ... -
Water Flow Requirements of Post-smolt Atlantic Salmon (Salmo salar L.) Reared in Intensive Seawater Flow-through Systems: A Physiological Perspective
(Journal article; Peer reviewed, 2023)Environmental challenges related to open sea cage production of Atlantic salmon have sparked interest in developing commercial-scale semi-closed sea systems for post-smolt Atlantic salmon (100–1000 g). Determining the ... -
Water level fluctuations and the ecosystem functioning of lakes
(Peer reviewed; Journal article, 2018-08-28)Hydrological regimes are key drivers of productivity and structure in freshwater ecosystems but are increasingly impacted by human activity. Using 17 published food web models of 13 African lakes as a case study, we explored ... -
Water masses constrain the distribution of deep-sea sponges in the North Atlantic Ocean and Nordic Seas
(Journal article; Peer reviewed, 2021)Water masses are bodies of water with distinctive physical and biogeochemical properties. They impart vertical structure to the deep ocean, participate in circulation, and can be traced over great distances, potentially ... -
Water temperature and dietary histidine affect cataract formation in Atlantic salmon (Salmo salar L.) diploid and triploid yearling smolt
(Peer reviewed; Journal article, 2017-09)The aim of the present study was to investigate cataract development in diploid (2N) and triploid (3N) Atlantic salmon smolts and post-smolts at two water temperatures (10 and 16 °C) given diets with different histidine ... -
WEBnm@: a web application for normal mode analyses of proteins
(Peer reviewed; Journal article, 2005-12-30)Background: Normal mode analysis (NMA) has become the method of choice to investigate the slowest motions in macromolecular systems. NMA is especially useful for large biomolecular assemblies, such as transmembrane channels ... -
Weichselian vegetation and palaeoenvironment in western Norway and northern Russia. Evidence from pollen analytical investigations
(Doctoral thesis, 2012-06-14)This thesis focuses on the vegetation history and environmental changes in western Norway and northern Russia during the last glacial period (the Weichselian). Pollen grains deposited in lakes and bogs are used as the main ... -
Welfare and efficiency of warm and cold waterfall (low pressure flushing) as delousing treatment of Atlantic salmon (Salmo salar)
(Master thesis, 2021-06-01)Salmonid aquaculture plays an important role in increasing global fish production and the biggest factor constraining its further growth and development in Norway is salmon lice (Lepeophtheirus salmonis). Previous projects ... -
What can selection experiments teach us about fisheries-induced evolution?
(Peer reviewed; Journal article, 2014-03)There is evidence that fisheries are altering the phenotypic composition of fish populations, often in ways that may reduce the value of fish stocks for the exploiters. Despite the increasing number of theoretical and field ... -
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 ... -
What is natural? The importance of a long-term perspective in biodiversity conservation and management
(Peer reviewed; Journal article, 2006)Ecosystems change in response to factors such as climate variability, invasions, and wildfires. Most records used to assess such change are based on short-term ecological data or satellite imagery spanning only a few ... -
What is the observed relationship between species richness and productivity? Comment

What we do in the dark: Prevalence of omnivorous feeding activity in Arctic zooplankton during polar night
(Journal article; Peer reviewed, 2023)During the productive polar day, zooplankton and sea-ice amphipods fulfill a critical role in energy transfer from primary producers to higher trophic-level species in Arctic marine ecosystems. Recent polar night studies ... -
When to reproduce? A new answer to an old question
(Peer reviewed; Journal article, 2016-04)We present a life-history model based on the assumptions that juvenile survival follows a negative exponential function and that fecundity gain increases linearly with time to maturity. This model predicts that the optimal ... -
Whole genome resequencing reveals diagnostic markers for investigating global migration and hybridization between minke whale species
(Peer reviewed; Journal article, 2017-01-13)Background: In the marine environment, where there are few absolute physical barriers, contemporary contact between previously isolated species can occur across great distances, and in some cases, may be inter-oceanic. An ... -
Why do birds lay eggs that fail to hatch?
(Master thesis, 2019-06-22)In birds, an average of 10-15% of eggs reportedly fail to hatch and remain in the nest after completed incubation. This is due to either fertilization failure or embryo death. Hatchability (the proportion of eggs hatching) ...
