Fluxes of carbon and nutrients to the Iceland Sea surface layer and inferred primary productivity and stoichiometry
(Peer reviewed; Journal article, 2015-02-12)This study evaluates long-term mean fluxes of carbon and nutrients to the upper 100 m of the Iceland Sea. The study utilises hydro-chemical data from the Iceland Sea time series station (68.00° N, 12.67° W), for the years ... -
Foam Generation and Flow in Fractures with Different Aperture
(Master thesis, 2017-06-20)This experimental thesis investigate foam generation and flow properties in real, rough-walled fractures, through impermeable marble core plugs. A range of fracture apertures was investigated, denoted open, partially open ... -
Food characteristics and territory habitat selection in Lapland longspurs Calcarius lapponicus in the early part of the breeding season at Hardangervidda, southern Norway
(Master thesis, 2017-05-04)Climate change currently affects the whole globe. Especially tundra and alpine areas are expected to change in the coming decades, affecting the species which today inhabits these areas. The Lapland longspur Calcarius ... -
Food intake, growth, and expression of neuropeptides regulating appetite in clown anemonefish (Amphiprion ocellaris) exposed to predicted climate changes
(Journal article; Peer reviewed, 2021)The clown anemonefish (Amphiprion ocellaris) is a common model species in studies assessing the impact of climate changes on tropical coral fish physiology, metabolism, growth, and stress. However, the basic endocrine ... -
Food preferences throughout the menstrual cycle – A computer-assisted neuro-endocrino-psychological investigation
(Journal article; Peer reviewed, 2022)Background As eating behavior changes in relation to the menstrual cycle and weight changes with menopausal transition, ovarian hormones appear to be involved in regulating eating behavior. However, observations are ... -
Food resource uncertainty shapes the fitness consequences of early spring onset in capital and income breeding migratory birds
(Journal article; Peer reviewed, 2022)Due to climate change, the timing of spring arrival and nesting onset in many migratory bird species have advanced. Earlier spring onsets prolong the available breeding period but can also deteriorate local conditions, ... -
Food uptake, lipid transport and vitellogenesis in the sea anemone Nematostella vectensis
(Doctoral thesis, 2021-09-20)Balancing energy input and output is crucial for the survival of all organisms, and involves the coordination of many physiological processes such as food uptake, nutrient storage, reproduction and growth. The uptake of ... -
Food web functions and interactions during spring and summer in the arctic water inflow region: Investigated through inverse modeling
(Peer reviewed; Journal article, 2019-05-28)We used inverse modeling to reconstruct major planktonic food web carbon flows in the Atlantic Water inflow, east and north of Svalbard during spring (18–25 May) and summer (9–13 August), 2014. The model was based on three ... -
Foraging behaviour of larval cod (Gadus morhua) at low light intensities
(Peer reviewed; Journal article, 2011-02-13)The ability to forage at lowlight intensities can be of great importance for the survival of fish larvae in a pelagic environment. Three-dimensional silhouette imaging was used to observe larval cod foraging and swimming ... -
Foraging ecology and learning. Adaptive behavioural strategies and the value of information
(Doctoral thesis, 2006-12-12)All animals face the challenge of acquiring resources for growth, survival, and reproduction. In environments that vary in time and space, foragers need to make apparently complex foraging decisions on which prey to select, ... -
Foraging success in planktivorous fish increases with topographic blockage of prey distributions
(Journal article; Peer reviewed, 2020)Banks and shelves are productive zones of the ocean, and often home to large fish stocks. Can shallower bottom topographies improve foraging opportunities for pelagic fish by blocking zooplankton from hiding in deep, darker ... -
Foraging tactics in dynamic sea-ice habitats affect individual state in a long-ranging seabird
(Journal article; Peer reviewed, 2020)1. Individual heterogeneity in diet and foraging behaviour is common in wild animal populations, and can be a strong determinant of how populations respond to environmental changes. Within populations, variation in foraging ... -
Forced and internal components of observed Arctic sea-ice changes
(Journal article; Peer reviewed, 2023)The Arctic sea-ice cover is strongly influenced by internal variability on decadal timescales, affecting both short-term trends and the timing of the first ice-free summer. Several mechanisms of variability have been ... -
Forced regression in rift shoulder derived deltas
(Master thesis, 2018-06-30)Footwall uplift and migration of fault activity have led to the preservation of spectacular down-stepping Gilbert-type deltas at the southern margin of the Corinth Rift. It is the purpose of this thesis to present the ... -
Forecasting Electricity Production from Photovoltaic Solar Panels using Elastic Net Regularization

Forest fragmentation modifes the composition of bumblebee communities and modulates their trophic and competitive interactions for pollination
(Journal article; Peer reviewed, 2020)Understanding the effects of landscape fragmentation on global bumblebee declines requires going beyond estimates of abundance and richness and evaluating changes in community composition and trophic and competitive ... -
Forkunnskaper i biologiundervisningen: En kvalitativ studie av læreres begrunnelse for hvorfor og hvordan man kan inkludere elevers forkunnskaper i undervisningen
(Master thesis, 2018-06-27)Studien handler om læreres forståelse av temaet forkunnskaper: hvorfor er det viktig å inkludere den kunnskapen elevene besitter, samt metoder for hvordan man kan inkludere denne kunnskapen. Inkludering av forkunnskaper ... -
Formation and Growth of Clusters of Sulfur Dioxide
(Peer reviewed; Journal article, 2015-06-01)Formation and growth of neutral SO2 clusters is investigated in an adiabatic-expansion setup by means of sulfur 2p (S2p) photoelectron spectroscopy and theoretical modeling. The shift in S2p ionization energy between the ... -
Formation and pathways of dense water in the Nordic Seas
(Doctoral thesis, 2023-10-20)Sammendrag De nordiske hav er viktig for dannelsen av kalde, tette og dype vannmasser som strømmer sørover på tvers av Grønland-Skottland-ryggen og forsyner den dype grenen av omveltningssirkulasjonen i Atlanterhavet. På ...
