Blood and feather concentrations of toxic elements in a Baltic and an Arctic seabird population
(Journal article; Peer reviewed, 2017)Wereport blood and feather concentrations of elements in the Baltic Sea and Arctic population of common eiders (Somateria mollissima). The endangered Baltic Sea population of eiders was demonstrably affected by element ... -
Body mass growth in nestlings of Svalbard snow buntings (Plectrophenax nivalis) in response to seasonal variation in arthropod biomass
(Master thesis, 2020)Hekkende fugler står overfor et utall avveininger i løpet av deres livssyklus for å maksimere overlevelse og reproduksjon som fører til høy levedyktighet. For trekkfugler inkluderer en av disse avveiningene når de skal ... -
Boolean modeling of macrophage polarization upon immune stimulation and SARS-CoV-2 infection
(Master thesis, 2022)Macrophages are specialized cells of the immune system that can polarize into different phenotypes depending on local conditions, classically an inflammatory macrophage (M1) and alternatively an anti-inflammatory macrophage ... -

Bottom-up and top-down control mechanisms affecting the feeding and growth of the cultivated barnacle Balanus crenatus
(Master thesis, 2022)Sammendrag Kultivering av skipsrur (Balanus crenatus) som blir benyttet til produksjon av levende-fôr til marin fiskeyngel, har vist seg å være utfordrende. Problemet er ikke å få dem til å vokse, men å forstå de biotiske ... -
Breathing in the Cold: Seasonal Changes in the Ventilatory Pattern in a Small Boreal Passerine Bird
(Peer reviewed; Journal article, 2022)Small passerine birds in the north need to take advantage of several behavioral and physiological mechanisms to maintain energy balance during the winter characterized by low food supply, low ambient temperatures, and short ... -
Breeding ecology of Kori Bustard Ardeotis kori strunthiunculus in the Serengeti National Park
(Journal article; Peer reviewed, 2018)The breeding ecology of the Kori Bustard Ardeotis kori strunthiunculus was studied in the plains of the Serengeti National Park, Tanzania in 2014 and 2015. Random transects were used to search for male courtship displays, ... -
Breeding success in Arctic snow buntings (Plectrophenax nivalis) in relation to climatic variations
(Master thesis, 2012)The ongoing global warming is especially pronounced in the arctic, and it is therefore important to investigate the effect of these changes on arctic ecosystems. In this study the Snow bunting (Plectrophenax nivalis) ... -
Breeding success of the Gyrfalcon (Falco rusticolus) in northern Norway in relation to food supply and weather
(Master thesis, 2012)Food supply and weather are among the main factors limiting bird numbers. In raptors prey availability may be closely linked to the reproduction output while weather conditions most often act indirectly by modifying food ... -
Broad-scale distribution of the winter protozooplankton community in the North Sea.
(Journal article; Peer reviewed, 2018)Protozooplankton (PZP) (here size range: 12–200 μm) are rarely sampled over a broad scale, especially in ecosystem monitoring programs, despite their trophodynamic importance as grazers in the microbial loop and as prey ... -
Brood Parasitism in Asian Cuckoos: Different Aspects of Interactions between Cuckoos and their Hosts in Bangladesh
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:198, Doctoral thesis, 2011)The interaction between brood parasitic cuckoos and their hosts represents a traditional example of coevolution, whereby obligate interspecific brood parasitic cuckoos completely rely on their hosts to do their parental ... -
