Development and evaluation of 16 new microsatellite loci for the rock ptarmigan (Lagopus muta) and cross-species amplification for the willow grouse (L. lagopus)
(Journal article; Peer reviewed, 2018)Abstract The genetic markers designed for this study can facilitate future genetic studies on the rock ptarmigan (Lagopus muta). To our knowledge no microsatellite markers have ever been developed specifically for this ... -
Differences in the vertical distribution pattern of Betula pubescens in Norway and its ecological significance
(Chapter; Peer reviewed, 1996)Several factors influence the altitudinal position of the climatic forest-limit. In addition to variations due to different "forest-limit" definitions, topographic factors are very important. In Western Norway, a range of ... -
Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
(Peer reviewed; Journal article, 2022)1. The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy ... -
The distribution limit of the common tick, Ixodes ricinus, and some associated pathogens in north-western Europe
(Peer reviewed; Journal article, 2020)In north-western Europe, the common tick, Ixodes ricinus, is widely established, its distribution appears to be increasing and the spread of tick-borne diseases is of increasing concern. The project ‘Flått i Nord’ (Ticks ... -
Distribution of allele frequencies for genes associated with physical activity and/or physical capacity in a homogenous Norwegian cohort- a cross-sectional study
(Journal article; Peer reviewed, 2020)Background There are large individual differences in physical activity (PA) behavior as well as trainability of physical capacity. Heritability studies have shown that genes may have as much impact on exercise participation ... -
Distribution of Neoehrlichia mikurensis in Ixodes ricinus ticks along the coast of Norway: The western seaboard is a low-prevalence region
(Journal article; Peer reviewed, 2019)Neoehrlichia mikurensis is a tick‐borne pathogen widespread among ticks and rodents in Europe and Asia. A previous study on Ixodes ricinus ticks in Norway suggested that N. mikurensis was scarce or absent on the south‐west ... -
Diversity in prevalence and genospecies of Borrelia burgdorferi sensu lato in Ixodes ricinus ticks and rodents in Lithuania and Norway
(Journal article; Peer reviewed, 2008)A total of 1679 questing Ixodes ricinus ticks collected in Lithuania and 535 I. ricinus ticks collected in Norway from locations with different habitats were investigated for the presence of Borrelia burgdorferi sensu lato. ... -
Diversity of thermophilic Campylobacter isolated from slaughter pigs in Norway
(Journal article; Peer reviewed, 2008)Out of 100 faecal swab samples, 88 thermophilic Campylobacter representing ten herds were isolated. The species were identified by biotyping and multiplex polymerase chain reaction (PCR). Of the isolates, 86 (97.7%) were ... -
Diversity of thermophilic Campylobacter isolated from the Bø River, Southeast Norway
(Journal article; Peer reviewed, 2009)Out of 125 samples we isolated 45 thermophilic Campylobacter spp. from Bø River by filtration followed by growth on selective agar plates. The species were identified by biotyping, multiplex PCR and riboprinting. C. jejuni ... -
Diving behavior in a free-living, semi-aquatic herbivore, the Eurasian beaver Castor fiber
(Journal article; Peer reviewed, 2017)Semi-aquatic mammals have secondarily returned to the aquatic environment, although they spend a major part of their life operating in air. Moving both on land, as well as in, and under water is challenging because such ... -
Do bank voles (Myodes glareolus) trapped in live and lethal traps show differences in tick burden?
(Peer reviewed; Journal article, 2020)In studies assessing tick abundance, the use of live traps to capture and euthanize rodent hosts is a commonly used method to determine their burden. However, captive animals can experience debilitating or fatal capture ... -
Do Eurasian beavers smear their pelage with castoreum and anal gland secretion
(Journal article; Peer reviewed, 2002)The scent-matching hypothesis postulates that scent marks provide an olfactory link between a resident owner and his territory, and that this enables intruding animals to recognize the chance of escalated conflicts. However, ... -
Do Scandinavian brown bears approach settlements to obtain high-quality food?
(Journal article; Peer reviewed, 2014)Large carnivores that approach human settlements are usually considered a threat to human property and safety. The prevailing paradigm, that such ‘problem’ animals approach settlements in search of food, ignores their ... -
Doctorateness across Higher Education Institutions in Norway
(Journal article; Peer reviewed, 2020)This article investigates doctorateness in Norway by evaluating the juridical regulations for doctoral studies at all PhD-awarding universities and university colleges according to the following categories: admission, ... -
Does despotic behavior or food search explain the occurrence of problem brown bears in Europe?
(Journal article; Peer reviewed, 2014)Bears foraging near human developments are often presumed to be responding to food shortage, but this explanation ignores social factors, in particular despotism in bears. We analyzed the age distribution and body condition ... -
Drivers of soil temperature variation in alpine lichen heaths and shrub vegetation during the summer
(Peer reviewed; Journal article, 2023)Lichen heaths are decreasing in abundance in alpine and Arctic areas because of an increased competition with shrubs. This shift in vegetation might have important consequences for the soil temperature. The aim of this ... -
Echinococcus multilocularis Detection in Live Eurasian Beavers (Castor fiber) Using a Combination of Laparoscopy and Abdominal Ultrasound under Field Conditions
(Journal article; Peer reviewed, 2015-07-15)Echinococcus multilocularis is an important pathogenic zoonotic parasite of health concern, though absent in the United Kingdom. Eurasian beavers (Castor fiber) may act as a rare intermediate host, and so unscreened wild ... -
Ecological impact of beavers Castor fiber and Castor canadensis and their ability to modify ecosystems
(Journal article; Peer reviewed, 2005)The genus Castor comprises two species: the Eurasian beaver Castor fiber, and the North American beaver Castor canadensis. Both species suffered from overexploitation, but have seen a revival since the 1920s due to increased ... -
Ecological implications from spatial patterns in human-caused brown bear mortality
(Journal article; Peer reviewed, 2016)Humans are important agents of wildlife mortality, and understanding such mortality is paramount for effective population management and conservation. However, the spatial mechanisms behind wildlife mortality are often ... -
