Navigating the Red Fox’s Cognitive Map : How recursive use of resource locations influence movement patterns and the notion of a home range.
(Master thesis, 2018)The size and location of an animal’s home range is considered fundamental to the understanding of a species’ dispersion and spatio-ecological requirements. Recent studies suggest that memory and recursive movement strategies ... -
Non-native brook charr (Salvelinus fontinalis) in an urban fragmented stream : Migration, growth, survival, and size at maturation
(Master thesis, 2012)English: Urbanization is a serious threat to stream ecosystems. Culverts fragment habitats, and can function as migration barriers. If migratory individuals are prevented to move between important habitats, this could ... -
On the way to independence : Ebbing cohesion in Scandinavian wolf family groups
(Master thesis, 2018)Sosial organisering er av stor betydning for å kunne forstå enkeltindividers områdebruk i tid og rom, men også demografiske, fitnessrelaterte, og overordnede populasjonsdynamiske prosseser. Den grunnleggende sosiale enheten ... -
Out Standing in Their Field: Factors Influencing Cattle Habitat Selection in Norwegian Outfields
(Master thesis, 2023)Releasing cattle (Bos taurus) to graze in outfields during the summer months has been a traditional practice in Norway for centuries. While outfields provide a low-cost and efficient method of feeding the cattle in summer, ... -
Patterns of reproduction and body condition in Red fox (Vulpes vulpes)
(Master thesis, 2014)Scandinavian red fox populations are commonly considered to be driven by the cyclicity of small rodent populations. It was recently suggested that the red fox’ general dependency of voles is becoming less pronounced due ... -
Population viability analysis of Swedish and Norwegian rock ptarmigan Lagopus muta populations
(Master thesis, 2011)Population viability analysis (PVA) is a method of projecting the likely future state of a population or populations of a species using quantitative methods. It is principally used to determine the population(s) risk of ... -
Possible underestimation of salmon lice (Lepeophtheirus salmonis) abundance using sentinel cages
(Master thesis, 2018)One of the biggest challenges related to salmon lice today is to get an accurate estimate of lice in its infectious life stage. A standard method to quantify this is to use sentinel cages with salmon smolts. In this study ... -
Post capture activity level recovery times of Eurasian lynx Lynx lynx in Norway
(Master thesis, 2015)Chemical immobilizations and handlings are commonly performed on numbers of wild animals each year and are the main methods for radio collaring, collecting biological samples and measurements, and obtaining information ... -
Predation on Artificial nests; can it predict actual nest loss in capercaillie Tetrao Urogallus?
(Master thesis, 2016)Reduserte bestander av alpine og subalpine arter antas å være et resultat fra en eller flere mulige årsaker; (1) abiotiske og klimatiske drivere, (2) endring i arealbruk, (3) introduserte predatorer, eller (4) økt ... -
Predicting hunting success on willow ptarmigan using bag statistics and distance sampling estimates
(Master thesis, 2013)Willow ptarmigan is a popular game species for recreational hunting purpose throughout its range and long term harvest statistics are available for many areas. For the State owned land in Sweden hunting report rates are ... -
Quantification of food waste disposal in developed and developing countries: A Meta-Analysis
(Master thesis, 2022)Matsvinn er et aktuelt problem, der avfall genereres gjennom alle ledd i verdikjeden, og dette skjer i så vel utviklede som utviklingsland. Økende bekymring for matsikkerhet og miljøpåvirkninger tilskrevet matsvinn på grunn ... -
Recovery from experimental disturbance in alpine vegetation communities in central Norway
(Master thesis, 2017)Human activity has increased in alpine environments during the last decades and is expected to continue to increase. Alpine habitats are highly sensitive to anthropogenic disturbance, such as trampling or motorized ... -
Resource-use of crucian carp (Carassius carassius) in lakes with different predation risk
(Master thesis, 2020)Predator fish and prey its prey can have considerable effect on fish communities and can affect the behavior of its prey. stable isotope of carbon (d13C) and nitrogen (d15N can provide as a powerful and useful tool for ... -

(Master thesis, 2014-09-29)Sarcoptic mange, a parasitic disease caused by the mite Sarcoptes scabiei, is epidemic in red foxes Vulpes vulpes and reported on wolves Canis lupus in Scandinavia. The small, inbred wolf population of Scandinavia might ... -
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 ... -
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 ... -
Seasonal variation of spirurian nematode Mastophorus muris in water voles (Arvicola amphibius) in southern Sweden
(Master thesis, 2015)I studied the spirurian nematode (Mastophorus muris) in water voles (Arvicola amphibius) in southern Sweden. Limited information is known about this nematode particularly in water voles. Trapping was done using topcats in ... -
Sexual segregation in foraging of greater kudu (Tragelaphus strepsiceros) in a heterogeneous savanna, in Chobe National Park, Botswana
