Infiltrasjonsundersøkelse. Kytelia, Bø i Telemark
(Working paper, 1980) -
Inkoo and Sindbis viruses in blood sucking insects, and a serological study for Inkoo virus in semi-domesticated Eurasian tundra reindeer in Norway
(Peer reviewed; Journal article, 2022)Background: Mosquito-borne viruses pose a serious threat to humans worldwide. There has been an upsurge in the number of mosquito-borne viruses in Europe, mostly belonging to the families Togaviridae, genus Alphavirus ... -
Insights in the regulation of trimetylamine N-oxide production using a comparative biomimetic approach suggest a metabolic switch in hibernating bears
(Peer reviewed; Journal article, 2020)Experimental studies suggest involvement of trimethylamine N-oxide (TMAO) in the aetiology of cardiometabolic diseases and chronic kidney disease (CKD), in part via metabolism of ingested food. Using a comparative biomimetic ... -
The interplay between hunting rate, hunting selectivity, and reproductive strategies shapes population dynamics of a large carnivore
(Peer reviewed; Journal article, 2021)Harvest, through its intensity and regulation, often results in selection on female reproductive traits. Changes in female traits can have demographic consequences, as they are fundamental in shaping population dynamics. ... -
Invasive North American beaver Castor canadensis in Eurasia: a review of potential consequences and a strategy for eradication
(Journal article; Peer reviewed, 2012-12)Seven North American beavers Castor canadensis (Cc) were introduced into Finland in 1937 to supplement an ongoing reintroduction of the nearly extinct Eurasian beaver C. fiber (Cf). At that time, many zoologists recognised ... -
Investigating and analysing the summer season soil temperature conditions on the extensive green roofs in Oslo, Norway
(Peer reviewed; Journal article, 2020)Recently, green roofs have been investigated in-creasingly to improve the quality of municipal environment particularly to reduce the urban heat island effect and storm water runoff. Soil temperature is one of the most ... -
Investigation of small rodents as reservoirs hosts of Borrelia burgdorferi sensu lato in Lithuania and Norway
(Conference object, 2006) -
Investigations of waterborne pathogens in Eurasian beaver (Castor fiber) from Telemark county, Southeast Norway
(Journal article; Peer reviewed, 2001)The presence of pathogenic bacteria and parasites in drinking water is a well-known cause of human disease outbreaks. There is however, a lack of knowledge of the contamination routes to water. In Norway, the supply of ... -
Island biogeography theory explains the genetic diversity of a fragmented rock ptarmigan (Lagopus muta) population
(Peer reviewed; Journal article, 2019)The island biogeography theory is one of the major theories in ecology, and its applicability to natural systems is well documented. The core model of the theory, the equilibrium model of island biogeography, predicts that ... -
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 ... -
Jord som rensemedium for avløpsvann fra spredt bosetting og mindre boligfelt
(Working paper, 1980) -
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 ... -
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 ...
