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 ... -
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 ... -
Forståelse av naturlig seleksjon - En kvantitativ undersøkelse av elevers og studenters misoppfatninger knyttet til naturlig seleksjon ved bruk av Diagnostisk Test av Naturlig Seleksjon
(Master thesis, 2023-06-02)Forståelse av naturlig seleksjon og evolusjon kan gi elever og studenter en dypere innsikt i sammenhenger i naturen og hvor viktig det er å bevare det biologiske mangfoldet. Imidlertid er det mange misoppfatninger knyttet ... -
Fossil pollen and spores as a tool for reconstructing ancient solar-ultraviolet irradiance received by plants: an assessment of prospects and challenges using proxy-system modelling
(Peer reviewed; Journal article, 2019)Ultraviolet-B radiation (UV-B, 280–315 nm) constitutes less than 1% of the total solar radiation that reaches the Earth's surface but has a disproportional impact on biological and ecological processes from the individual ... -
Fractal hypothesis of the pelagic microbial ecosystem-can simple ecological principles lead to self-similar complexity in the pelagic microbial food web?
(Peer reviewed; Journal article, 2015-12-01)Trophic interactions are highly complex and modern sequencing techniques reveal enormous biodiversity across multiple scales in marine microbial communities. Within the chemically and physically relatively homogeneous ... -
A framework for the development of a global standardised marine taxon reference image database (SMarTaR-ID) to support image-based analyses
(Peer reviewed; Journal article, 2019-12-31)Video and image data are regularly used in the field of benthic ecology to document biodiversity. However, their use is subject to a number of challenges, principally the identification of taxa within the images without ... -
Francisella philomiragia subsp. noatunensis i torskeleukocytter
(Master thesis, 2009-06-22)Det er velkjent at en rekke intracellulære bakterier, inkludert flere arter innen slekten Francisella, har evne til å oppholde seg og formere seg i immuncellene. I dette studiet ble det utført smitteforsøk in vitro der det ... -
Fresh- or seawater eels, or mixed life history strategies: what do the parasites tell?

Freshwater small pelagic fish and fisheries in the main African great lakes and reservoirs in relation to food security and nutrition
(Research report, 2019)This paper reviews the status and importance of the freshwater small pelagic fish and fisheries for sustainable healthy livelihoods in Africa. The lack of recognition of the importance of small pelagic fish for the sustenance, ... -
From a crisis to an opportunity: Eight insights for doing science in the COVID‐19 era and beyond
(Journal article; Peer reviewed, 2020)The COVID-19 crisis has forced researchers in Ecology to change the way we work almost overnight. Nonetheless, the pandemic has provided us with several novel components for a new way of conducting science. In this perspective ... -
From complex to simple: Myogenesis in an aplacophoran mollusk reveals key traits in aculiferan evolution
(Peer reviewed; Journal article, 2015-09-18)Background: Recent studies suggest a bifurcation at the base of Mollusca, resulting in the primarily single-shelled Conchifera (Bivalvia, Gastropoda, Scaphopoda, Monoplacophora, Cephalopoda) and the spicule-bearing Aculifera ... -
From notochord to vertebral column: studies on Atlantic salmon (Salmo salar L.)
(Doctoral thesis, 2007-05-11)The notochord initially form a single-cell file stage of chordoblasts covered by a three layered sheath comprising a basal lamina, a main collagenous layer and an external elastic membrane. During early ontogeny, the ... -
From pollen percentage to vegetation cover – evaluation ofthe Landscape Reconstruction Algorithm in western Norway
(Peer reviewed; Journal article, 2015-06-23)The Landscape Reconstruction Algorithm (LRA) with the two models REVEALS and LOVE is developed to transform pollen percentage data to vegetation cover. This paper presents the first study to evaluate LRA in a region with ... -
From self-interest to cooperation: extra-pair mating as a driver of relaxed territorial aggression in social neighbourhoods
(Journal article; Peer reviewed, 2023)In socially monogamous bird species, males and females tailor their reproductive strategies to that of the other. Interactions are complex, and have elements of both conflict and cooperation. Breeding process is further ... -
From sensing to emergent adaptations: Modelling the proximate architecture for decision-making
(Peer reviewed; Journal article, 2016-04)During the past 50 years, evolutionary theory for animal behaviour has branched into different methodological frameworks focussing on age-, state-, density-, and frequency-dependent processes. These approaches have led to ... -
From the fjords to the rivers: Evaluating the spatial distribution of escaped farmed salmon to inform ecologically relevant management strategies
(Doctoral thesis, 2020-05-08)Over the last 40 years, the relatively fast expansion of Atlantic salmon aquaculture has created new obstacles for the persistence of wild Atlantic salmon stocks where the two overlap. Now, the greatest threat to existing ...
