Global maps of soil temperature
(Journal article; Peer reviewed, 2021)Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation ... -
Global phylogeography suggests extensive eucosmopolitanism in Mesopelagic Fishes (Maurolicus: Sternoptychidae)
(Journal article; Peer reviewed, 2020)Fishes in the mesopelagic zone (200–1000 m) have recently been highlighted for potential exploitation. Here we assess global phylogeography in Maurolicus, the Pearlsides, an ecologically important group. We obtained new ... -
Global reconstruction of life-history strategies: A case study using tunas
(Peer reviewed; Journal article, 2019)1. Measuring the demographic parameters of exploited populations is central to predicting their vulnerability and extinction risk. However, current rates of population decline and species loss greatly outpace our ability ... -
A global-scale screening of non-native aquatic organisms to identify potentially invasive species under current and future climate conditions
(Journal article; Peer reviewed, 2021)The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced species are likely to pose an elevated risk of impact to native species and ecosystems. To inform policy, ... -
Globally important plant functional traits for coping with climate change
(Journal article; Peer reviewed, 2021)The last decade has seen a proliferation of studies that use plant functional traits to assess how plants respond to climate change. However, it remains unclear whether there is a global set of traits that can predict ... -
Going With the Flow – Population Genetics of the Kelp Saccharina latissima (Phaeophyceae, Laminariales)
(Journal article; Peer reviewed, 2022)Saccharina latissima is the most important habitat-forming kelp in sheltered areas of North-Atlantic, and there is also an increasing interest in cultivation and utilization of S. latissima. The cultivation activity may ... -
Gonadal Degeneration and Hepatopancreas Alteration in Orange Mud Crab Scylla olivacea Infected With Sacculina beauforti (Crustacea; Rhizocephala; Sacculinidae)
(Journal article; Peer reviewed, 2020)Infestation of Sacculina beauforti on an aquaculture species, mud crab Scylla olivacea is alarming due to its high prevalence and the extreme morphological changes in hosts. To further understand its pathological effect ... -
Gorgonophilus canadensis (Copepoda: Lamippidae) a parasite in the octocoral Paragorgia arborea – relation to host, reproduction, and morphology
(Journal article; Peer reviewed, 2022)The family Lamippidae (Cyclopoida) are endosymbionts mainly occurring in shallow water octocorals and records from deep-sea corals are few. Here we investigated the relationship between the lamippid Gorgonophilus canadensis ... -
Gray whale habitat use and reproductive success during seismic surveys near their feeding grounds: comparing state-dependent life history models and field data
(Journal article; Peer reviewed, 2022)We used a stochastic dynamic programming (SDP) model to quantify the consequences of disturbance on pregnant western gray whales during one foraging season. The SDP model has a firm basis in bioenergetics, but detailed ... -
Grazing on Marine Viruses and Its Biogeochemical Implications
(Journal article; Peer reviewed, 2023)Viruses are the most abundant biological entities in the ocean and show great diversity in terms of size, host specificity, and infection cycle. Lytic viruses induce host cell lysis to release their progeny and thereby ... -
Growth and competition in a warmer ocean: a field experiment with a non-native and two native habitat-building seaweeds
(Peer reviewed; Journal article, 2017-06-21)Kelps and fucoids are important members of temperate seaweed communities, but may be negatively impacted by climate change and non-native species. We used a field experiment to investigate the effect of higher temperatures ... -
Growth and diel vertical migration patterns of the toxic dinoflagellate Protoceratium reticulatum in a water column with salinity stratification: the role of bioconvection and light
(Peer reviewed; Journal article, 2015-11-12)Novel data on growth and migratory behaviour of a southern Norwegian strain of Protoceratium reticulatum (Dinophyceae) were obtained from long-lasting (14-22 d) experiments in a water column with salinity gradient (ΔS = 4 ... -
Growth and energy metabolism in Atlantic salmon (Salmo salar), with possible positive effects of starvation at elevated temperature
(Master thesis, 2014-02-25)Due to global warming, the sea water temperature will probably increase, which may affect cold- water species like Atlantic salmon. It is therefore of great importance to see how elevated temperature will affect the growth ... -
Growth characteristics and morphology of Paramoeba perurans from Atlantic salmon Salmo salar L. and ballan wrasse Labrus bergylta in Norway
(Journal article; Peer reviewed, 2023)Background Paramoeba perurans is the causative agent of amoebic gill disease (AGD) in Atlantic salmon Salmo salar L. and many other farmed marine fish species worldwide. The first cases of AGD in Norway were reported in ... -
Growth of Atlantic salmon (Salmo salar) under different regimes of continuous aerobic exercise
(Master thesis, 2023-06-02)To ensure the Atlantic salmon aquaculture industry's sustainable growth, the development and implementation of new production strategies is needed. A strategy that has been adopted by the industry to intensify the salmon’s ... -
Growth Performance, Nutrient Digestibility, and Retention in Atlantic Salmon, Salmo salar L., Fed Diets with Fermented Sugar Kelp, Saccharina latissima
(Journal article; Peer reviewed, 2023)Using low trophic marine resources such as sugar kelp (Saccharina latissimi) is of great interest to increase the circular food production in the ocean. Sugar kelp does, however, contain high levels of carbohydrates and ... -
Growth portfolios buffer climate-linked environmental change in marine systems
(Journal article; Peer reviewed, 2022)Large-scale, climate-induced synchrony in the productivity of fish populations is becoming more pronounced in the world's oceans. As synchrony increases, a population's “portfolio” of responses can be diminished, in turn ... -
Growth reaction norms of domesticated, wild and hybrid Atlantic salmon families in response to differing social and physical environments
(Peer reviewed; Journal article, 2013-10-28)Background: Directional selection for growth has resulted in the 9-10th generation of domesticated Atlantic salmon Salmo salar L. outgrowing wild salmon by a ratio of approximately 3:1 when reared under standard hatchery ... -
