Redd Site Micro-Habitat Selection and Quantitative Analyis for Large Brown Trout in the Tokkeåi River Telemark, Norway
(Master thesis, 2018)The study of redd site microhabitat selection is very important for successful conservation and management of large brown trout. Number of redds is quantified by several reports before but this research has done microstudy ... -
Rekruttering av brunørret fra naturlig rennende vann med residual-, regulert vannføring. Populasjonsdynamikk i innsjøer i Kova øvre, Telemark.
(Master thesis, 2023)Det presserende globale behovet for mer og bedre bevaring av natur synes ofte å være i konflikt med det like store behovet for økt produksjon av fornybar, bærekraftig energi. Slike interessekonflikter spilles ofte ut på ... -
Relationship between modelled drift of eggs and larvae and the geographical variation in recruitment of cod (Gadus morhua) and pollack (Pollachius pollachius) in Tvedestrandsfjorden
(Master thesis, 2016-01-18)Oceanographic current models are frequently used to predict particle drift in marine ecosystems. In our study, eggs and larvae of cod (Gadus morhua) and pollack (Pollachius pollachius) are used as particles in the model ... -
Retensjon av organiske miljøgifter frå deponi og slamkomposteringsanlegget ved Goasholtmyra, Notodden
(Master thesis, 2021)Organiske miljøgifter har fysisk-kjemiske eigenskapar som gjer dei til ein global trugsel mot menneskeleg helse og miljø. Sigevatn frå deponi inneheld organiske miljøgifter og tungmetall som potensielt kan entre miljøet ... -
Review of microsatellites in ecology and parentage analysis of Norwegian beavers (Castor fiber) based on cross-specific microsatellites
(Master thesis, 2009)The Eurasian Beaver (Castor fiber) in Scandinavia was once close to extinction due to a bottleneck resulting from vigorous overhunting in the middle of the 19th century. After measures of protection, the population number ... -
Sand temperatures at sea turtle nesting beaches at the Pacific coast of Guatemala
(Master thesis, 2020)The climate is changing, bringing extremities such as increased periods of rainfall, but also draughts and warming temperatures. There are several species with presumed little capacity to adapt to climate changes, such as ... -
Seasonal and spatial variation in the macroparasite fauna of Arctic charr (Salvelinus alpinus L.) in Lake Norsjø, South-Eastern Norway
(Master thesis, 2019)Within freshwater systems, several factors contribute to aggregated distributions of parasites in fish. Niche segregation, individual feeding preferences, sex of the host, and water temperature are all examples of such ... -
Seasonal variations in the use of profundal habitat among freshwater fishes in Lake Norsjø, southern Norway, and subsequent effects on fish mercury concentrations.
(Master thesis, 2016-01-18)This study is based on monthly sampling of fish from an industrial water intake, located at the bottom of Lake Norsjø, at a depth of 50 m, during one year (2014). By this sampling strategy, we have obtained unique information ... -
Selection of aquatic vegetation in river habitats by Eurasian beaver (Castor fiber) in South-Eastern Norway
(Master thesis, 2020)Habitat selection in animals is evident when the choosing of habitat is disproportionate to its availability, usually when habitat characteristics differ in quantity and quality. A very important factor of their use is the ... -
Selection of rubbing trees by brown bears in Slovakia
(Master thesis, 2018)Chemical communication in bears is not fully understood, despite the importance of this topic for the behavioral ecology as well as for the conservation and management of Ursids. Brown bears often mark trees by rubbing on ... -
Short-term effects of bio-logging on body mass and growth of a semi-aquatic mammal, the Eurasian beaver (Castor fiber)
(Master thesis, 2020)Bio-logging is a popular method to collect scientific data in the field of animal ecology. The presumption is that bio-logging should allow the study of animals with only minor disturbance to their natural behaviour and ... -
