Ixodes ricinus and Borrelia prevalence at the Arctic Circle in Norway
(Peer reviewed; Journal article, 2014)The distribution limit of Ixodes ricinus ticks in northwestern Europe (Brønnøy, Norway, 1° south of the Arctic Circle), has been known since the 1930s. To reconfirm this finding and extend studies in the areas adjacent to ... -

Koppermangel hos oppdrettshjort
(Journal article; Peer reviewed, 2001)Raising red deer in enclosures for meat production is a relatively new practice in Norway and is based on national stocks (Cervus elaphus atlanticus). Presently only 400 - 500 hinds are reared in enclosures by 25 ... -
Landscape genetics of northern crested newt Triturus cristatus populations in a contrasting natural and human-impacted boreal forest
(Peer reviewed; Journal article, 2020)Among vertebrates, amphibians currently have the highest proportion of threatened species worldwide, mainly through loss of habitat, leading to increased population isolation. Smaller amphibian populations may lose more ... -
Landscape of fear or landscape of food? Moose hunting triggers an antipredator response in brown bears
(Peer reviewed; Journal article, 2023)Hunters can affect the behavior of wildlife by inducing a landscape of fear, selecting individuals with specific traits, or altering resource availability across the landscape. Most research investigating the influence of ... -
Landscape use and economic value of Eurasian beaver (Castor fiber) on large forest in southeast Norway
(Conference report, 1999)Though numerous studies of damage caused by beaver (Castor canadensis and C. fiber) to commercially managed forests have been conducted, few have incorporated the economic advantages beaver can create for forest owners. ... -
The last glaciation of the Arctic volcanic island Jan Mayen
(Peer reviewed; Journal article, 2020)The volcanic island of Jan Mayen, remotely located in the Norwegian‐Greenland Sea, was covered by a contiguous ice cap during the Late Weichselian. Until now, it has been disputed whether parts of the island south of the ... -
Life histories and ecotype conservation in an adaptive vertebrate: Genetic constitution of piscivorous brown trout covaries with habitat stability
(Journal article; Peer reviewed, 2018)Ecotype variation in species exhibiting different life history strategies may reflect heritable adaptations to optimize reproductive success, and potential for speciation.Traditionally, ecotypes have, however, been defined ... -
Litter loss triggers estrus in a nonsocial seasonal breeder
(Journal article; Peer reviewed, 2014)Sexually selected infanticide (SSI) is often presumed to be rare among seasonal breeders, because it would require a near immediate return to estrus after the loss of an entire litter during the mating season. We evaluated ... -
Lone male loser? Effects of spatial isolation on male pairing success in the ortolan bunting Emberiza hortulana
(Peer reviewed; Journal article, 2023)In small, isolated or fragmented bird populations, past studies have shown that there can be a high proportion of unpaired males. Low male pairing success is suggested to be the result of female-biased natal dispersal and ... -
Long-term responses of Icelandic Arctic foxes to changes in marine and terrestrial ecosystems
(Peer reviewed; Journal article, 2023)The long-term dynamics of predator populations may be driven by fluctuations in resource availability and reflect ecosystem changes such as those induced by climate change. The Icelandic Arctic fox (Vulpes lagopus) population ... -
Longitudinal studies on Listeria monocytogenes and other Listeria species in two salmon processing plants
(Journal article; Peer reviewed, 2005)Two plants processing salmon fillets and cold smoked salmon were investigated for occurrence of Listeria in products and the environment. Analyses were conducted for a period of 31 weeks. At plant A, 252 samples were ... -
Low prevalence of tick-borne encephalitis virus antibodies in Norwegian blood donors
(Peer reviewed; Journal article, 2020)Background: Tick-borne encephalitis (TBE) constitutes a public health concern in Europe. Certain coastal municipalities in southern Norway are considered TBE risk areas and in the last two years, there have been increasing ... -
Low-density debris flows and floods modeling in the Susuya river basin
(Journal article; Peer reviewed, 2020)Significant area of Yuzhno-Sakhalinsk city within the river Susuya flood plain, a terrace above it and its tributaries are located in flood prone zone. The aim of this research was to estimate maximum characteristics of ... -

Malnutrition in farmed red deer hinds (Cervus elaphus atlanticus) in Norway
(Research report, 2005)Malnutrition was studied in farmed red deer. Malnourished animals did not recover from winter energy loss, remained in poor condition throughout the summer, and some died of starvation. Liver analysis of one hind that died ... -
Merging and comparing three mitochondrial markers for phylogenetic studies of Eurasian reindeer (Rangifer tarandus)
(Journal article; Peer reviewed, 2016)Phylogenetic analyses provide information that can be useful in the conservation of genetic variation by identifying intraspecific genetic structure. Reconstruction of phylogenetic relationships requires the use of markers ... -
Meta-Analysis of 1,200 Transcriptomic Profiles Identifies a Prognostic Model for Pancreatic Ductal Adenocarcinoma
(Peer reviewed; Journal article, 2019)PURPOSE: With a dismal 8% median 5-year overall survival, pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy. Only 10% to 20% of patients are eligible for surgery, and more than 50% of these patients ... -
Metabolic reprogramming involving glycolysis in the hibernating brown bear skeletal muscle
(Journal article; Peer reviewed, 2019)Background In mammals, the hibernating state is characterized by biochemical adjustments, which include metabolic rate depression and a shift in the primary fuel oxidized from carbohydrates to lipids. A number of studies ... -
