Will Trespassers Be Prosecuted or Assessed According to Their Merits? A Consilient Interpretation of Territoriality in a Group-Living Carnivore, the European Badger (Meles meles)
(Journal article; Peer reviewed, 2015-07-06)Socio-spatial interactions of Carnivores have traditionally been described using the vocabulary of territoriality and aggression, with scent marks interpreted as ‘scent fences’. Here, we investigate the role of olfactory ... -
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 ... -
A "clearcut" case? Brown bear selection of coarse woody debris and carpenter ants on clearcuts
(Journal article; Peer reviewed, 2015-07-05)Forest management alters habitat characteristics, resulting in various effects among and within species. It is crucial to understand how habitat alteration through forest management (e.g. clearcutting) affects animal ... -
Captive care and welfare considerations for beavers
(Journal article; Peer reviewed, 2015-03-01)Beavers (Castor spp.) tend not to be a commonly held species and little published material exists relating to their captive care. We review published material and discuss husbandry issues taking into account the requirements ... -
The hydrogeological and cultural background for two sacred springs, Bø, Telemark County, Norway
(Journal article; Peer reviewed, 2015-05-14)Of the many sacred springs in Norway, most dedicated to St. Olav, several have disappeared. Two of the sacred springs that still exist are located in Bø in Telemark, Southern Norway, and have been surveyed for their ... -
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 ... -
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 ... -
Quantifying long-term stress in brown bears with the hair cortisol concentration: a biomarker that may be confounded by rapid changes in response to capture and handling
(Journal article; Peer reviewed, 2014)The measurement of cortisol in hair is becoming important in studying the role of stress in the life history, health and ecology of wild mammals. The hair cortisol concentration (HCC) is generally believed to be a reliable ... -
Behavioral correlates of supplementary feeding of wildlife: Can general conclusions be drawn?
(Journal article; Peer reviewed, 2014-10-12)Supplementary feeding is a common, but controversial, tool in wildlife management, because it can benefit both humans and wildlife (e.g., increased wildlife densities), but has certain downsides (e.g., increased disease ... -
Sex discrimination via anal gland secretion in a territorial monogamous mammal
(Journal article; Peer reviewed, 2014-07-12)Monogamy in mammals is relatively unusual, only occurring in 3-5% and to an even lesser degree in rodents. Monogamy exists in two forms, facultative which evolved due to female dispersion and obligate when male care is ... -
The relative importance of direct and indirect effects of hunting mortality on the population dynamics of brown bears
(Journal article; Peer reviewed, 2014)There is increasing evidence of indirect effects of hunting on populations. In species with sexually selected infanticide (SSI), hunting may decrease juvenile survival by increasing male turnover. We aimed to evaluate the ... -
Resipientundersøkelse ved østsiden av Kloumannsjøen, Notodden kommune. Registrering av utslipp og forslag til løsninger
(Working paper, 1980)Notodden kommune har gitt Telemark distriktshøgskole i oppgave å kartlegge eksisterende utslipp langs Kloumannsjøen og finne løsninger for direkte og uheldige utslipp. -
The effects of wildfire on the water chemistry of dilute, acidic lakes in southern Norway
(Journal article; Peer reviewed, 2014-01-22)Changes in lake water chemistry were studied for >4 years following a large wildfire in a boreal forest area in Mykland, southern Norway, an area characterized by thin and patchy, base-poor and slow-weathering soils and ... -
Soil temperature variation in calciphile mountain plant communities in Southern Norway
(Journal article; Peer reviewed, 2012)Soil temperature dynamics are considered to be of great importance for alpine plant life. The aim of this study was to analyse differences in soil temperature parameters between and within exposed ridges, leesides, and ... -
Infanticide as a male reproductive strategy has a nutritive risk effect in brown bears
(Journal article; Peer reviewed, 2013-10-02)Behavioural strategies to reduce predation risk can incur costs, which are often referred to as risk effects. A common strategy to avoid predation is spatio-temporal avoidance of predators, in which prey typically trade ... -
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 ... -
Temperature and Precipitation Development at Svalbard 1900-2100
(Journal article; Peer reviewed, 2011-12-06)Substantial variations in temperature and precipitation have been observed since the first permanent weather station was established in the Svalbard region in 1911. Temperature and precipitation development are analysed ... -
The importance of chemical communication studies to mammalian conservation biology: A review
(Journal article; Peer reviewed, 2011-05-14)The relevance of chemical communication to mammalian conservation is not often the focus of scientific investigation. Our review identifies and discusses ten key areas in which the study of chemical communication aids ... -
Brown bears possess anal sacs and secretions may code for sex
(Journal article; Peer reviewed, 2010-09-14)Olfactory communication occurs in carnivores and many scent-mark with anal gland secretions (AGS), which contain a variety of information including sex-related cues. Currently, there is disagreement about whether bear ... -
The level of claudin-7 is reduced as an early event in colorectal carcinogenesis
(Journal article; Peer reviewed, 2011-02-10)BACKGROUND: Compromised epithelial barriers are found in dysplastic tissue of the gastrointestinal tract. Claudins are transmembrane proteins important for tight junctions. Claudins regulate the paracellular transport and ...
