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) ... -

Environmental factors influencing mercury speciation in Subarctic and Boreal lakes
(Journal article; Peer reviewed, 2014)Environmental drivers of total mercury (TotHg) concentrations, methylmercury (MeHg) concentrations, and MeHg fractions (a proxy for methylation potential, expressed as %MeHg) were assessed in a synoptic study of 51 lakes ... -
Errors associated with moose-hunter counts of occupied beaver Castor fiber lodges in Norway
(Journal article; Peer reviewed, 2002)In Norway, Sweden and Finland moose Alces alces hunting teams are often employed to survey occupied beaver (Castor fiber and C. canadensis) lodges while hunting. Results may be used to estimate population density or trend, ... -
Estimation of lichen biomass with emphasis on reindeer winter pastures at Hardangervidda, S Norway
