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 ... -
Effect of Aerobic Exercise Intensity on Energy Expenditure and Weight Loss in Severe Obesity—A Randomized Controlled Trial
(Journal article; Peer reviewed, 2021)Objective: This study aimed to compare the effects of two aerobic exercise programs of different intensities on energy expenditure. Methods: This was a single‐center randomized controlled trial of patients with severe ... -
Effect of aerobic exercise intensity on health-related quality of life in severe obesity: a randomized controlled trial
(Peer reviewed; Journal article, 2022)Background: Aerobic exercise is an important part of obesity treatment and may improve health-related quality of life (HRQOL). The objective of this study was to compare the effect of two different exercise programs on ... -
Effect of latitude and mountain height on the timberline (Betula pubescens ssp. czerpanovii) elevation along the central Scandinavian mountain range
(Journal article; Peer reviewed, 2015)Previously published isoline maps of Fennoscandian timberlines show that their highest elevations lie in the high mountain areas in central south Norway and from there the limits decrease in all directions. These maps are ... -
Effectiveness of predator odors as gray squirrel repellents
(Journal article; Peer reviewed, 2001)The ability of gray squirrels (Sciurus carolinensis) to discriminate between different predator odors and the use of predator odors to deter gray squirrels from foraging on plants have not been previously investigated. To ... -
Efficacy of cartridge type and projectile design in the harvest of beaver
(Journal article; Peer reviewed, 2006)In Norway, Sweden, and Finland most beavers (Castor spp.) harvested are shot with center-fire rifles. Shooting entails problems not encountered in trapping including pelt damage from bullet holes (body shots are common) ... -
