Flower imprints from the history of mires and humans : A palynological study of rich fen development and periods of human land use over the last 8000 years in boreal Norway
(Doctoral thesis, 2024-06-25)Kulturvegetasjon på boreale slåttemyrer har for første gong vorte rekonstruert tilbake til den romerske jernalderen. Slåtten på myrene heldt fram til midten av 1900-talet i norske utmarker, og representerer ein del av den ... -
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 ... -
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 ... -
