Denning ecology of Scandinavian brown bears (Ursus Arctos) in a dynamic landscape
(Master thesis, 2016-08-31)Human encroachment, habitat fragmentation, resource exploitation, and hunting can affect the presence, habitat use, behavior, life history, and population dynamics of wildlife species. Wide-ranging large mammals with low ... -
Density and bending properties of Norway spruce (Picea abies (L.) Karst.) structural timber – Inherent variability, site effects in machine strength grading and possibilities for presorting
(PhD Thesis;2016:43, Doctoral thesis, 2020-11-19)Density, modulus of elasticity (MOE) and bending strength (MOR) are the most important properties for structural timber. These properties vary significantly within European species, both between and within countries. The ... -
Deponering och rotupptag av 238U, 232Th, 226Ra och 228Ra i bär och tillhörande bladverk från områden med förhöjda nivåer av naturligt förekommande radioaktivitet
(Master thesis, 2021)Naturliga radionuklider förekommer med varierande koncentrationer i jordmånen och kan överföras till vegetation genom rotupptag eller deponering. Överföringen estimeras vanligen genom transferfaktorn, en väletablerad ... -
Depreciative tourist behaviour in a protected birdwatching site : a qualitative study of birdwatchers on Hornøya, Northern Norway
(Master thesis, 2019)Wildlife watching tourism is a growing industry and can become eco-friendly if sufficient conservation measures are actively included in the operative tourism strategies. Research on visitor behaviour is necessary to ... -
Desalination of groundwater by solar stills : field trials in Afghanistan
(Master thesis, 2014-11-03)Lack of clean drinking water is amongst the leading problems in Afghanistan, especially in form of salinity, being amongst the main concerns. As an attempt to find sustainable solutions, low cost solar stills were designed ... -
Destination image : a case study of Norwegian anglers at an Alaskan salmon fishing lodge
(Master thesis, 2016-08-31)Salmon anglers travel all over the world to get the best fishing experiences. The present study investigates how a specific destination image correlates with visitors’ destination preferences. This research is based on 17 ... -
Detection and quantification of arsenolipids in human breast milk by HPLC-ICP-MS and HPLC-ESI-MS : method optimization to enable quantification of six arsenolipids at low concentration levels
(Master thesis, 2018)Recent research has shown that some arsenic containing lipids, common components of seafood, are highly cytotoxic and have the potential to cross the blood-brain barrier. Infants, in particular, are especially sensitive ... -
Detection of root and butt rot in Norway Spruce (Picea Abies) using airborne hyperspectral images and laser scanning
(Master thesis, 2020)The forest is an important renewable resource in a sustainable bioeconomy. Yearly, fungal decay causes economical losses that exceed 100 million NOK within the Norwegian forest sector. Root and butt rots are the main ... -
Detection of tire and road wear particles in duck mussels (Anodonta anatina) from a road-near lake in Norway using various analytical techniques
(Master thesis, 2022)Microplastic particles (MP) in the environment are an emerging problem, and the environmental impacts are still to be completely understood. It is known that small plastic particles have been in the environment for a long ... -
Deteksjon av pionertrær i tregrenseøkotonen ved bruk av tredimensjonale punktskyer fra bildematching
(Master thesis, 2019)Tregrenseøkotonen (overgangssonen mellom skog og treløst alpint område) har alltid vært i endring. I en periode med økning i gjennomsnittstemperatur og en endring i arealbruken, er tregrenseøkotonen forventet å etablere ... -
Determinants of domestic cat ocurrence in forests in southeastern Norway
(Master thesis, 2022)Domestic cats can pose a significant threat to local wildlife in urban and rural areas because of their high densities and proficiency as predators. However, few attempts have been made to quantify the impact of domestic ... -
Determinants of habitat utilization patterns of European lobsters (Homarus gammarus) in the Inner Oslo Fjord, Norway
(Master thesis, 2022)Habitat type and structure influences diversity body size, recruitment, population size structure and survival of species in marine communities. There is, however, inadequate empirical evidence on what substitutes ... -
Determinants of scent-marking behavior by Asiatic cheetahs (Acinonyx jubatus venaticus) at camera traps in Iran
(Master thesis, 2021)Scent marking is a common behaviour in large carnivores and serves a multiple of ecological purposes. It functions as a method of communication, either to warn off intruders, attract mates or to mark territory. In surveys ... -
Determination of elements in snow and water samples on Jan Mayen
(Master thesis, 2022)Iceland is considered one of the greatest dust emission sources in the Arctic. Once the dust is deposited, it significantly affects snow and ice albedo. This hastens the glacier melting and leads to new accessible dust ... -
