Scavenger community on wolf-killed ungulates in the boreal forest in south-east Norway
(Master thesis, 2022)Åtselspising er en av flere fôringsstrategier for å utnytte matressurser, og en viktig økologisk prosess i nedbrytingen. Bruk av åter er vanlig i perioder med miljøstress, for eksempel ved mangel på byttedyrarter, og som ... -
Assessment of arterial oxygenation and acid-base status before and during oxygen therapy in captive European bison (Bison bonasus) immobilized with etorphine, acepromazine and xylazine
(Master thesis, 2022)Chemical immobilization of captive European bison (Bison bonasus) is often required for veterinary care, transport, or husbandry practices playing an important role in the reintroduction and preservation of the species. ... -
Monitoring reproduction in moose by use of unmanned aircraft system: - detectability, effectivity and behavioral responses
(Master thesis, 2022)Å forbedre metoder for blant annet tetthet- og reproduksjons studier er en del av forvaltningen og forskningens ansvar. Å utvikle og teste ny teknologi som kan forstyrre dyrene i mindre grad, men også være mer effektiv I ... -
Fantastic beavers (Castor fiber) and where to find them: Using availability of suitable habitat to estimate beaver populations sizes
(Master thesis, 2022)The Eurasian beaver was significantly over harvested for its pelt and for what is called castoreum, and the global population was estimated to be 1200 individuals. Today, the Eurasian beaver population is estimated to be ... -
Assessing the potential of camera traps for estimating activity pattern compared to GPS activity sensors: a case study on Eurasian lynx Lynx lynx in southeastern Norway
(Master thesis, 2022)Animals tend to have predictable activity patterns, based on their ecological and physiological needs, alternating between periods of activity and resting. Investigating factors influencing activity patterns for different ... -
Mortality Dynamics Across Time and Site Class Gradient
(Master thesis, 2022)Forest poses an important role by providing multiple ecological services such as regulating climate, recycling nutrients and carbon- storing etc. These services are highly dependent on the existing forest dynamics which ... -
The effect of aqueous aluminium on mortality and respiration in the amphipod Gammarus lacustris
(Master thesis, 2021)The literature covering freshwater acidification and Al-toxicity in aquatic organisms has mainly focused on fish species sensitivity to acidic Al-rich water. A thorough review of the literature shows that knowledge is far ... -
Eradicating the American bullfrog with the sterile triploid method: methods and application
(Master thesis, 2021)The American bullfrog, an invasive species present all around the world, causes many problems in ecosystems. They are very hard to eradicate because of their complex developmental stages, their abundance, high fertility, ... -
Insect Biodiversity and Biomass in a Forested Region in Belgium: A case study in Bosland, Limburg
(Master thesis, 2021)Insects, being the first in the food chain, form a perfect animal group to estimate the vitality of an ecosystem. Their diversity and abundance could have tremendous impact on plants and other animals living in the ecosystem. ... -
Brainworm (Elaphostrongylus rangiferi) abundance in wild reindeer (Rangifer tarandus tarandus) in relation to gastropod densities
(Master thesis, 2021)Elaphostrongylus rangiferi is a nematode parasite in reindeer (Rangifer tarandus) which can cause considerable neurological damage and could affect the survival chances of the last European wild tundra reindeer. The parasite ... -
Wolf space use in a seasonally changing environment
(Master thesis, 2021)In this study, we investigate the space use of a recolonizing predator in Scandinavia in relation to the density of its main prey and other environmental variables. Animal space use is influenced by intrinsic factors, ... -
Grazing among carnivores: Managing cattle depredation across the Western-world
(Master thesis, 2021)Large carnivores such as wolves and bears may prey on cattle. With the recent recovery of large carnivore populations in the Western world, cattle depredation is expected to increase. To mitigate potential conflicts, it ... -
Investigating the effect of herd and landscape factors on brainworm (Elaphostrongylus rangiferi) prevalence and infection intensity in a semi-domesticated reindeer (Rangifer tarandus tarandus) herd
(Master thesis, 2021)The increasing concern about brainworm (Elaphostrongylus rangiferi) in reindeer (Rangifer tarandus) is driven by climate change. The development of the nematode in its intermediate host – gastropods – is strongly affected ... -
Effects of reduced liming on brown trout (Salmo trutta L.) in four small tributaries in eastern Norway.
(Master thesis, 2020)Acidification of surface waters due to acidic precipitation has led to a reduction in biological diversity. Through international conventions, emissions causing the acidic precipitation has decreased. The hallenges associated ... -
Short-term effects of capture on movement of free-ranging Scandinavian brown bears
(Master thesis, 2020)Research of free-ranging wildlife often involves capture and chemical immobilization of animals. Such an invasive and stressful procedure may cause alterations in the animals’ physiology and behavior. Thus, evaluating the ... -
Scots pine (Pinus sylvestris) phytochemistry predicts male capercaillie (Tetrao urogallus) browsing during winter
(Master thesis, 2020)During winter, the capercaillie (Tetrao urogallus) faces harsh conditions with only heavily digestible food available. To cope with this, these birds consume large volumes to compensate for the low levels of digestible ... -
A comparison of body height in Crucian carp (Carassius carassius) in lakes with- and without predators
(Master thesis, 2020)Induced morphometrical defenses have been reported in crucian carp (Carassius carassius), and these defenses are presumed to be induced by predators. Crucian carp was sampled during 2018 and 2019 in 12 lakes in southeast ... -
Effects of GPS-collars on Svalbard reindeer survival and body condition
(Master thesis, 2020)Modern wildlife and conservation research often relies on GPS collars and on the assumption that collared animals are representative of the study population, but this assumption is rarely tested in the wild. These collars ... -
