Effect of immobilizations on female moose (Alces alces) activity and space use
(Journal article; Peer reviewed, 2011)Studies of free-ranging wildlife often involve animal capture and fitting of tracking devices. Capturing wildlife may result in behavioral alterations. Thus, there is a need to evaluate the effects of capture on study ... -
Effects of different doses of medetomidine and tiletamine-zolazepam on the duration of induction and immobilization in free- ranging yearling brown bears (Ursus arctos)
(Journal article; Peer reviewed, 2012)We compared anesthetic protocols with different doses of tiletamine-zolazepam (TZ) combined with medetomidine (M) for 288 yearling brown bear (Ursus arctos) immobilizations with the objective of finding a combination of ... -
Elgbeiting påvirker kvaliteten på musematen
(Journal article, 2011)Elgbeiting forandrer kvaliteten på blåbærlyng som mus eter. Fjellmarkmus foretrekker tidligere beitet blåbærlyng i næringsrike områder og unngår tidligere beitet blåbærlyng fra områder med liten næringstilgang. -
Experimental harvest reveals the importance of territoriality in limiting the breeding population of Svalbard rock ptarmigan
(Journal article; Peer reviewed, 2013)The Svalbard rock ptarmigan (Lagopus muta hyperborea) is an endemic sub-species of rock ptarmigan inhabiting the high-Arctic archipelagos of Svalbard and Franz Josefs Land. This ptarmigan species exists at low population ... -
Factors affecting deer ked (Lipoptena cervi) prevalence and infestation intensity in moose (Alces alces) in Norway
(Journal article; Peer reviewed, 2012)Background: The deer ked (Lipoptena cervi), a hematophagous ectoparasite of Cervids, is currently spreading in Scandinavia. In Norway, keds are now invading the south-eastern part of the country and the abundant and ... -
Field Anesthesia of Least Weasels (Mustela nivalis nivalis) with Isoflurane
(Journal article; Peer reviewed, 2013)The aggressive and agile nature of weasels makes the use of inhalant anesthetics preferable to injectable agents because inhalant anesthetics generally reduce handling time, cause less stress and present no risk of delivering ... -
Food distribution influences social organization and population growth in a small rodent
(Journal article; Peer reviewed, 2013)In polygynous mammals, the spatial clumping and predictability of food should influence spacing behavior of females whose reproductive success depends to a great extent on food availability, which would in turn affect male ... -
From individuals to population cycles: the role of extrinsic and intrinsic factors in rodent populations
(Journal article; Peer reviewed, 2016)Rodent population cycles have fascinated scientists for a long time. Among various hypotheses, an interaction of an extrinsic factor (predation) with intrinsic factors (e.g., sociality and dispersal) was suggested to ... -
Gastrointestinal nematodes of moose (Alces Alces) in relation to supplementary feeding
(Peer reviewed; Journal article, 2013)Winter supplementary feeding of wildlife is controversial because it may promote parasite and disease transmission by host aggregation. We investigated the effect of winter supplemental feeding of Scandinavian moose ... -
General Experience Rather Than of Local Knowledge is Important for Grouse Hunters Bag Size
(Journal article; Peer reviewed, 2012)Wildlife harvest management requires an understanding of hunter behavioral interactions with the game. Hunter harvest is indicated to be more dependent on experience and attitudes than game abundance. We tested how the ... -
Genetic Predictions of Prion Disease Susceptibility in Carnivore Species Based on Variability of the Prion Gene Coding Region
(Journal article; Peer reviewed, 2012)Mammalian species vary widely in their apparent susceptibility to prion diseases. For example, several felid species developed prion disease (feline spongiform encephalopathy or FSE) during the bovine spongiform encephalopathy ... -
Genotypic variation in safflower (Carthamus spp) cadmium accumulation and tolerance affected by temperature and cadmium levels
(Journal article; Peer reviewed, 2013)Soil pollution is a world-wide problem, with heavy metals being a major part of the concern. To investigate the effect of temperature on cadmium (Cd) uptake and translocation, as well as Cd tolerance in wild and cultivated ... -
Giraffe browsing in response to plant traits
(Journal article; Peer reviewed, 2016)Intake rates by large herbivores are governed by among other things plant traits. We used Masai giraffe (Giraffa camelopardalis tippelskirchi Matschie) as study animals, testing whether they as very large browsers would ... -
Grouse hunting regulations and hunter typologies in Norway
(Journal article; Peer reviewed, 2013)Sustainable game management relies on satisfied hunters. Satisfaction determinants are seldom uniform across all hunters and may therefore be difficult to accommodate. Latent class analysis (LCA) is a probabilistic model-based ... -
Haematology and Serum Biochemistry Parameters and Variations in the Eurasian Beaver (Castor fiber)
(Journal article; Peer reviewed, 2015)Haematology parameters (N = 24) and serum biochemistry parameters (N = 35) were determined for wild Eurasian beavers (Castor fiber), between 6 months – 12 years old. Of the population tested in this study, N = 18 Eurasian ... -
Health and Environmental Risks from Lead-based Ammunition: Science Versus Socio-Politics

Hierarchical foraging by giraffe in a heterogeneous savannah, Tanzania
(Journal article; Peer reviewed, 2016)Understanding foraging decisions made by wildlife at different spatio-temporal scales is important for wildlife management and conservation. We tested whether forag- ing decisions by Masai giraffe ( Giraffa ... -
High infection intensities, but negligible fitness costs, suggest tolerance of gastrointestinal nematodes in a tropical snake
(Journal article; Peer reviewed, 2015)We investigated patterns of prevalence and intensity of gastrointestinal nematode infections in a tropical natricine snake, the keelback (Tropidonophis mairii). Ninety-eight per cent of keelbacks were infected with Tanqua ... -
Hunting Bambi : evaluating the basis for selective harvesting of juveniles
(Journal article; Peer reviewed, 2011)Human harvesting is often a major mortality factor and, hence, an important proximate factor driving the population dynamics of large mammals. Several selective harvesting regimes focus on removing animals with low ... -
Improvement of arterial oxygenation in free-ranging moose (Alces alces) immobilized with etorphine-acepromazine-xylazine
(Journal article; Peer reviewed, 2014)Background The effect of intranasal oxygen and/or early reversal of xylazine with atipamezole on arterial oxygenation in free-ranging moose (Alces alces) immobilized with etorphine-acepromazine-xylazine with a cross-sectional ...
