High-throughput screening of ancient forest plant extracts shows cytotoxicity towards triple-negative breast cancer
(Peer reviewed; Journal article, 2023)According to the World Health Organization, women's breast cancer is among the most common cancers with 7.8 million diagnosed cases during 2016–2020 and encompasses 15 % of all female cancer-related mortalities. These ... -
Higher host plant specialization of root-associated endophytes than mycorrhizal fungi along an arctic elevational gradient
(Peer reviewed; Journal article, 2020)How community-level specialization differs among groups of organisms, and changes along environmental gradients, is fundamental to understanding the mechanisms influencing ecological communities. In this paper, we investigate ... -
Highways associated with expansion of boreal scavengers into the alpine tundra of Fennoscandia
(Peer reviewed; Journal article, 2020)1. Habitat fragmentation may affect species distributions through, for example, altered resource availability and shifts in species interactions. Fragmentation by roads has had negative impacts on Fennoscandian alpine ... -
Highways up the mountains: Trails as facilitators for redistribution of plant species in mountain areas.
(Doctoral theses at NTNU;2022:293, Doctoral thesis, 2022)To protect mountain ecosystems, their biodiversity, ecosystem services, and other contributions to people, it is necessary to understand how climate and disturbances affect them. Trails may change seed dispersal and disrupt ... -
Hiking trails shift plant species' realized climatic niches and locally increase species richness
(Peer reviewed; Journal article, 2022)Aim The presence and use of trails may change plant species' realized climatic niches via modified abiotic and biotic conditions including propagule transport, allowing competition-pressed alpine species to expand their ... -
Historical abundance and spatial distributions of spawners determine juvenile habitat accessibility in salmon: implications for population dynamics and management targets
(Journal article; Peer reviewed, 2013)Spatial distribution of spawning may have important ramifications for population dynamics in species where early life stages suffer from low mobility and high density-dependent mortality. Here, we use time series of spatial ... -
Hjortevilt 1991-2011. Oppsummeringsrapport fra Overvåkingsprogrammet for Hjortevilt
(NINA rapport;885, Research report, 2012)Overvåkingsprogrammet for hjortevilt blir gjennomført på oppdrag fra Direktoratet for naturforvaltning (DN), og NINA har hatt ansvaret for gjennomføringen av programmet siden oppstarten i 1991 og fram til i dag. Datamaterialet ... -
Hjortevilt og trafikk i Norge: En analyse av hjorteviltrelaterte trafikkulykker i perioden 1970-2007
(NINA Rapport;463, Research report, 2009)Hjorteviltet er en viktig naturressurs i Norge, med stor økonomisk og rekreasjonsmessig betyd-ning for jaktrettshavere og jegere. I takt med stadig økende bestandstetthet ser vi også økende samfunnskostnader forbundet med ... -
Home range and excursive post-breeding movements of Eurasian Eagle-owls revealed by GPS satellite transmitters
(Peer reviewed; Journal article, 2021)Investigating space use of wild birds provides important knowledge of bird behavior and ecology, which is crucial in the management and conservation of threatened species. In the present study, we used GPS satellite telemetry ... -
Home ranges and habitat utilisation of the river-resident Atlantic salmon, Salmo salar, småblank
(Master thesis, 2016)Home ranges and habitat utilisation of the river resident Atlantic salmon, småblank, Salmo salar, in Nord Trøndelag, Norway, were studied by the use of radio telemetry during the period August 2014 to January 2016. The aim ... -
Homology modeling to screen for potential binding of contaminants to thyroid hormone receptor and transthyretin in glaucous gull (Larus hyperboreus) and herring gull (Larus argentatus)
(Journal article; Peer reviewed, 2020)Thyroid hormone disrupting chemicals (THDCs) are of major concern in ecotoxicology. With the increased number of emerging chemicals on the market there is a need to screen for potential THDCs in a cost-efficient way, and ... -
Horizon scanning of potential new alien vascular plant species and their climatic niche space in the Arctic
(Master thesis, 2024)Biologiske invasjoner utgjør en eskalerende trussel mot Arktis grunnet økt menneskelig aktivitet og klimaendringer. Denne studien benyttet datadrevet horisontscanning for å identifisere potensielle nye fremmede karplanter ... -
Host selection in parasitic birds: are open-cup nesting insectivorous passerines always suitable cuckoo hosts?
(Journal article; Peer reviewed, 2013)How do potential hosts escape detrimental interactions with brood parasites? Current consensus is that hole-nesting and granivorous birds avoid brood parasites, like common cuckoos Cuculus canorus , by their inaccessible ... -
Household Reliance on Environmental Income in the Western Serengeti Ecosystem, Tanzania

How can mariculture better help feed humanity?
(Peer reviewed; Journal article, 2015)The primary production of the marine and the terrestrial domains are similar, ~49 and 56 Gt C year−1, respectively (Field et al., 1998), and the marine primary production must likely be more readily available for grazing ... -
How do conditions at birth influence early‐life growth rates in wild boar?
(Peer reviewed; Journal article, 2020)Weather conditions and population density individuals experience at birth influence their life-history traits and thereby population dynamics. Early-life individual growth is a key fitness-related trait; however, how it ... -
How do lichens, willow shrubs, meadow, and heath plant communities affect microclimate?
(Master thesis, 2022)Increases in earth's surface temperature because of climate change in the last decades have already shown consequences in different ecosystems and in different taxonomic groups. Alpine environments are among the most ... -
How does a forest herb species change its reproductive allocation patterns in response to microclimate variation
(Master thesis, 2019)Rapid environmental changes induced plant species to modify their migration range to meet ecological tolerance. It mainly brought difficulties to slow colonizing forest understory species, because such changes already ... -
How does human disturbance affect brood parasitism and nest predation in hosts inhabiting a highly fragmented landscape?
(Peer reviewed; Journal article, 2020)Human disturbance represents a considerable challenge for the conservation of living organisms and has profound negative impacts globally. There is substantial variation in how species respond to human disturbance. The ... -
How Does Spring Migration and Day Length Affect the Diving Ecology of a Capital Breeder Wintering at High Latitudes?
(Master thesis, 2016)Foraging strategies in animals are influenced by conflicting constraints such as migration, reproduction and seasonal changes in the environment. Sea ducks are capital breeders and rely on endogenous reserves for reproduction. ...
