Habitat fragmentation amplifies threats from habitat loss to mammal diversity across the world’s terrestrial ecoregions
(Peer reviewed; Journal article, 2021)Global biodiversity is increasingly threatened by anthropogenic environmental change. While there is mounting evidence that habitat loss is a key threat to biodiversity, global assessments typically ignore additional threats ... -
Habitat quality is more important than matrix quality for bird communities in protected areas
(Journal article; Peer reviewed, 2018)Protected areas are meant to preserve native local communities within their boundaries, but they are not independent from their surroundings. Impoverished habitat quality in the matrix might influence the species composition ... -
Habitat use and depth preferences of sea trout (Salmo trutta) in a Norwegian estuary
(Master thesis, 2020)Brunørreten (Salmo trutta) er en ferskvannsfisk som lever i bekker, elver, innsjøer og marine kystområder. Anadrome individer, ofte kalt sjøørret, har stor variasjon i migrasjonsstrategi og habitatbruk. De fleste større ... -
Habitat use in an estuary - a comparative study of Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) of two life stages
(Master thesis, 2022)Detaljer om hvordan atlantisk laks (Salmo salar) og sjøørret (Salmo trutta) utnytter elvemunningsområder blir stadig mer relevante i tråd med økosystembasert forvaltning. Til tross for åpenbare forskjeller i habitatbruk ... -
Habitat use of sea trout (Salmo trutta) veterans in two Norwegian estuaries
(Master thesis, 2022)Elvemunningar er eit viktig habitat for sjøaure (Salmot trutta) til alle årstider, og kan brukast gjennom vinterhalvåret som ein alternativ strategi til den meir vanlege overvintringa i ferskvatn. I denne studien blei ... -
Habitatkrav og habitattilgjengelighet for småblank: (Salmo salar), relikt laks i øvre Namsen
(Master thesis, 2010)Den relikte laksen i øvre Namsen, småblank (Salmo salar), er vurdert som kritisk truet i den norske rødlista. Småblank gjennomfører hele livssyklusen i elva uten å vandre ut til havet, noe som gjør den unik i europeisk ... -
Habituation and conditioning in gilthead sea bream (Sparus aurata): Effects of aversive stimuli, reward and social hierarchies
(Journal article; Peer reviewed, 2017)To tailor the farming environment to a fish species, we should understand the species-specific responses to stimuli, including the degree of adaption and learning. Groups of gilthead sea bream were given a delay Pavlovian ... -
Habituation to humans in a predator-free wild ungulate
(Journal article; Peer reviewed, 2014)Arctic caribou and reindeer face an increase in human activity, tourism and infrastructure, which impact may depend on the potential for habituation. Habituation to nonlethal human disturbance in wild animals depends on ... -
Hair mineral levels as indicator of wildlife demographics?—a pilot study of muskoxen
(Peer reviewed; Journal article, 2022)The tight linkage between mineral status and health and demographics in animals is well documented. Mineral deficiencies have been coupled to population declines in wildlife. Current practices typically rely on liver, ... -
Halogenated boroxine increases propensity to apoptosis in leukemia (UT‐7) but not non‐tumor cells in vitro
(Peer reviewed; Journal article, 2022)A hallmark of the development of solid and hematological malignancies is the dysregulation of apoptosis, which leads to an imbalance between cell proliferation, cell survival and death. Halogenated boroxine [K2(B3O3F4OH)] ... -
Halogenated Pyrrolopyrimidines with Low MIC on Staphylococcus aureus and Synergistic Effects with an Antimicrobial Peptide
(Peer reviewed; Journal article, 2022)Currently, there is a world-wide rise in antibiotic resistance causing burdens to individuals and public healthcare systems. At the same time drug development is lagging behind. Therefore, finding new ways of treating ... -
HAMLET forms annular oligomers when deposited with phoshpolipid monolayers
(Journal article; Peer reviewed, 2012)Recently, the anticancer activity of human α-lactalbumin made lethal to tumor cells (HAMLET) has been linked to its increased membrane affinity in vitro, at neutral pH, and ability to cause leakage relative to the inactive ... -
Handbook for the measurement of macrofungal functional traits: A start with basidiomycete wood fungi
(Journal article; Peer reviewed, 2018)Functional traits are widely recognized as a useful framework for testing mechanisms underlying species community assemblage patterns and ecosystem processes. Functional trait studies in the plant and animal literature ... -
Handling Discontinuities in Numerical ODE Methods
(Master thesis, 2021)Et vanlig ønske i mange typer arbeid er å finne den fremgangsmåten som gir best resultat uten å kreve for mye innsats. For eksempel så krever modellering av hvordan forurensende stoffer sprer seg i havet at man beregner ... -
"Hanging gardens" - comparing fauna communities in kelp farms and wild kelp forests
(Peer reviewed; Journal article, 2023)A growing need for food is causing increased interest for seaweed farming globally. This requires knowledge of the industry’s effects on the marine environment. We therefore aimed to explore the communities hosted by a ... -
