Annelid functional genomics reveal the origins of bilaterian life cycles
(Journal article; Peer reviewed, 2023)Indirect development with an intermediate larva exists in all major animal lineages1, which makes larvae central to most scenarios of animal evolution2,3,4,5,6,7,8,9,10,11. Yet how larvae evolved remains disputed. Here we ... -
Light and temperature controls of aquatic plant photosynthesis downstream of a hydropower plant and the effect of plant removal
(Journal article; Peer reviewed, 2023)Many rivers worldwide are regulated, and the altered hydrology can lead to mass development of aquatic plants. Plant invasions are often seen as a nuisance for human activities leading to costly remedial actions with ... -
Holocene changes in the position of the Southern Hemisphere Westerlies recorded by long-distance transport of pollen to the Kerguelen Islands
(Journal article; Peer reviewed, 2024)The Southern Hemisphere Westerlies (SHW) are a vital part of the Southern Hemisphere's coupled ocean-atmosphere system and play an important role in the global climate system. The SHW affect the upwelling of carbon-rich ... -
Winds of change : A multi-proxy approach to constrain Holocene climate and wind dynamics in the sub-Antarctic
(Doctoral thesis, 2024-09-05)Kunnskap om tidligere tiders naturlige klimavariasjoner er hovednøkkelen for å forstå vår nåværende klimatilstand. Det er også viktig for å kunne vurdere omfanget og retningen til fremtidige klimaendringer som forventes ... -
Metabolic pathways and physiological functions of organic and inorganic trace minerals in Atlantic Salmon
(Doctoral thesis, 2024-09-05)Mineralernæring spiller en nøkkelrolle for helse, velferd og prestasjonen til oppdrettet Atlantisk laks (Salmo salar), da den påvirker ulike fysiologiske prosesser, avgjørende for vekst, metabolisme og immunfunksjon. Blant ... -
Intermittent fasting in ongrowing Atlantic salmon (Salmo salar) reared in sea cages: Effects on feed intake, appetite control and growth
(Master thesis, 2023-11-20)Farmed Atlantic salmon are normally fed at a daily basis and fasted before operational procedures and harvest. While the biological mechanisms and effects of short and long-term fasting are largely known, there is sparse ... -
How formal initiatives to improve teaching can lead to more significant informal conversations and increased sharing practice
(Journal article; Peer reviewed, 2023)University teachers grow professionally from conversations about learning and teaching with colleagues. Significant informal conversations can be facilitated through formal activities initiated from the institutional side. ... -
Seasonality of the bacterial and archaeal community composition of the Northern Barents Sea
(Journal article; Peer reviewed, 2023)The Barents Sea is a transition zone between the Atlantic and the Arctic Ocean. The ecosystem in this region is highly variable, and a seasonal baseline of biological factors is needed to monitor the effects of global ... -
In vitro responses of fin whale (Balaenoptera physalus) fibroblasts to plasticizers and their metabolites
(Master thesis, 2024)Phthalates, plasticizers that maintain plastic’s durability and flexibility, are chemicals that leach from plastics into the environment. As endocrine disruptors, they can bind to nuclear receptors regulating metabolism ... -
Bergmann patterns in planktivorous fishes: A light-size or zooplankton community-size rule is just as valid explanation as the temperature-size rule
(Journal article; Peer reviewed, 2024)Aim Bergman patterns, the tendency of organisms to be larger at higher latitudes and lower temperatures, are a well-studied biogeographic pattern. Yet, there is no consensus on the driver or underlying mechanisms. We ... -
Short- and long-term plant and microbial uptake of 15N-labelled urea in a mesic tundra heath, West Greenland
(Journal article; Peer reviewed, 2024)Terrestrial animals are key elements in the cycling of elements in the Arctic where nutrient availability is low. Waste production by herbivores, in particular urine deposition, has a crucial role for nitrogen (N) recycling, ... -
Long-term trajectories of non-native vegetation on islands globally
(Journal article; Peer reviewed, 2023)Human-mediated changes in island vegetation are, among others, largely caused by the introduction and establishment of non-native species. However, data on past changes in non-native plant species abundance that predate ... -
Hidden in the fog: Morphological and molecular characterisation of Derogenes varicus sensu stricto (Trematoda, Derogenidae) from Sweden and Norway, and redescription of two poorly known Derogenes species
(Journal article; Peer reviewed, 2023)Derogenes varicus (Müller, 1784) is widely reported as a trematode with exceptionally low host specificity and a wide, bipolar distribution. However, several recent studies have suggested that D. varicus represents a species ... -
Greenland and Canadian Arctic ice temperature profiles database
(Journal article; Peer reviewed, 2023)Here, we present a compilation of 95 ice temperature profiles from 85 boreholes from the Greenland ice sheet and peripheral ice caps, as well as local ice caps in the Canadian Arctic. Profiles from only 31 boreholes (36 %) ... -
Emergence of games from ecological trade-offs: longevity changes strategies for extra-pair mating in birds
(Journal article; Peer reviewed, 2023)Each member of a breeding pair benefits if the other does more of the parental investment, so there is scope for behaviours that can be interpreted as both cooperative and competitive games between males and females. ... -
Aquaporin splice variation differentially modulates channel function during marine teleost egg hydration
(Journal article; Peer reviewed, 2023)Aquaporin-mediated oocyte hydration is a developmentally regulated adaptive mechanism that co-occurs with meiosis resumption in marine teleosts. It provides the early embryos with vital water until osmoregulatory systems ... -
Temporal changes in boreal vegetation under 70 years of conservation
(Journal article; Peer reviewed, 2023)Biodiversity conservation through protected areas (PAs) is often based on the idea that biodiversity is relatively static. This assumption is increasingly being challenged as species and communities shift their distributions ... -
Brain asymmetry is globally different in males and females: exploring cortical volume, area, thickness, and mean curvature
(Journal article; Peer reviewed, 2023)Brain asymmetry is a cornerstone in the development of higher-level cognition, but it is unclear whether and how it differs in males and females. Asymmetry has been investigated using the laterality index, which compares ... -
IDEAcology: An interface to streamline and facilitate efficient, rigorous expert elicitation in ecology
(Journal article; Peer reviewed, 2023)Here, we demonstrate how IDEAcology aids in preparing for and implementing a structured expert elicitation using the IDEA protocol, an iterative quantitative expert elicitation framework. Expert judgement is used to inform ... -
Belowground niche partitioning is maintained under extreme drought
(Journal article; Peer reviewed, 2024)Belowground niche partitioning presents a key mechanism for maintaining species coexistence and diversity. Its importance is currently reinforced by climate change that alters soil hydrological conditions. However, ...
