Five reasons to take the precautionary approach to deep sea exploitation
(Journal article, 2023)Extractive activities in the deep sea are poised to advance faster than the science needed to evaluate risks. Here, we call for a strong precautionary approach in developing these industries. -
Fjellflora og -vegetasjon i midtre Hordaland. Analyse av en botanisk øst-vest-gradient
(Master thesis, 1985) -
Flesh quality of Atlantic salmon smolts reared at different temperatures and photoperiods
(Peer reviewed; Journal article, 2019)Possible interactive effects of temperature and photoperiod on flesh quality in Atlantic salmon post‐smolts were studied. Juvenile (initial mean weight 96.0 g ± 3.1 SEM ) Atlantic salmon were reared at six different ... -
Flexible behaviour in a mesopelagic fish (Maurolicus muelleri)
(Journal article; Peer reviewed, 2021)Variability of mesopelagic scattering layers is often attributed to environmental conditions or multi-species layer composition. Yet, little is known about variation in behaviour among the individuals forming scattering ... -
The flickering connectivity system of the north Andean páramos
(Peer reviewed; Journal article, 2019-06-13)Aim: To quantify the effect of Pleistocene climate fluctuations on habitat connectivity across páramos in the Northern Andes. Location: Northern Andes. Methods: The unique páramos habitat underwent dynamic shifts in elevation ... -
Flow Cytometric Analysis of Bacterial Protein Synthesis: Monitoring Vitality After Water Treatment
(Journal article; Peer reviewed, 2021)Bacterial vitality after water disinfection treatment was investigated using bio-orthogonal non-canonical amino acid tagging (BONCAT) and flow cytometry (FCM). Protein synthesis activity and DNA integrity (BONCAT–SYBR ... -
Flow cytometric quantification of viruses in activated sludge
(Peer reviewed; Journal article, 2015-10-18)Viruses may play a critical role in the microbial dynamics of activated sludge systems; however the difficulty of their quantification makes long term and large scale studies costly, timely and challenging. Thus a flow ... -
Flower morphology variation in five species of Penstemon (Plantaginaceae) displaying Hymenoptera pollination syndrome
(Journal article; Peer reviewed, 2023)Background: Geographic distance promotes phenotypic variation by facilitating environmental distance, limiting gene flow, and exposing plants to different pollen vectors. Therefore, understanding how plant morphology changes ... -
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 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 ... -
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 ...
