Disentangling the effect of physical and chemical factors on phytoplankton dynamics in a highly eutrophic and turbid lake
(PhD Thesis;2012:11, Doctoral thesis, 2012)The fact that nutrients limit primary production in aquatic ecosystems is widely accepted, and phosphorus is demonstrated as the main limiting nutrient in freshwaters. Strict control of phosphorus supply has therefore ... -
Distribution and mobility of 137Cs in soil from the cathcment area of Vefsna
(Master thesis, 2022)The primary source of 137Cs in Norway is the Chernobyl accident, and several decades after the accident, there is still a substantial amount in the environment. The area of Hattfjelldal, within the catchment area of the ... -
Distribution Modeling of Vegetation Types in Venabygdsfjellet, Oppland.
(Master thesis, 2014-08-06)This study explores the effect of increasing sample units density with presence-only data (PO data) on the ability to predict the distribution of three common (2e dwarf shrub heath, 4b bilberry birch forest and 9c fen) ... -
Distribution of metals and organic material along a Norwegian river - ocean transect
(Master thesis, 2021)The distribution of metals in aquatic systems is crucial for bioavailability and toxicity. Metals are transported from catchment to oceans through rivers. During this transport, the properties of metals (e.g., charge, size, ... -

(Master thesis, 2012-05-21)The present study focus on the distribution of Plecoptera, Ephemeroptera and Trichoptera in an alpine stream system, related to environmental variables. The study was conducted in the valley Øvre Heimdalen situated in the ... -
Distribution, Age and Growth Dynamics of Scots Pine Recruits on Its Northern Distributional Limit in Norway
(Master thesis, 2023)Growth and age structures of Scots pine (Pinus sylvestris L.) at its northern distribution are influenced by both regional climate and microsite conditions. While large-scale trends for stand regeneration and annual growth ... -
Diversity of wild bees in semi-natural grasslands in southeast Norway is related to temperature and amount of edge habitat in the surrounding landscape
(Master thesis, 2021)The declines in diversity and abundance of wild bees are mainly attributed to the intensification of agricultural practices and the resulting loss of semi-natural grassland habitats. Furthermore, the effect of climate ... -
Do individual differences in use of cover habitat affect red deer`s (Cervus elaphus) probability of being shot by hunters?
(Master thesis, 2014-08-19)The purpose of this study was to test if red deer (Cervus elaphus) habitat use affects their risk of being shot by hunters. I compared habitat use of 20 GPS-marked red deer that survived the hunting season with 20 individuals ... -
Do juvenile densities in the river Bognelv experience density dependency after river restoration and do the reopened side channel function as suitable nursing areas for juvenile brown trout (Salmo trutta)
(Master thesis, 2020)Det eksister ennå usikkerheter rundt den biologiske effektivitet rundt elverestaurering, til tross for mengden litteratur og finansiering som eksister oppgjennom historien. Dette setter lys på viktigheten forskning har for ... -
Do nitrogen-fixing legumes affect soil nutrient levels, plant growth or community properties of an alpine ecosystem?
(Master thesis, 2011-04-27)In this master thesis I examine how two N-fixing legume species, Astragalus alpinus L. and Oxytropis lapponica (Wahlenb.) Gay, affect different aspects of an alpine ecosystem in two sites situated along a gradient in ... -
Dobbeltpredasjon i et heterogent landskap : er det forskjeller i risikohabitat for hjort og rådyr?
(Master thesis, 2013-08-06)Uttrykket ”fryktens landskap” ble innført som en visuell modell for å forklare hvordan frykt kunne endre byttedyrs atferd og arealbruk for å redusere risikoen for å bli drept når predatorer er tilstede. Ulike habitater ... -
Does species richness and abundance of saproxylic beetles differ between old near-natural and old managed forest in south-eastern Norway?
(Master thesis, 2016-08-31)Humans have altered almost all forests on earth through the need for forest resources. Several scientific papers show that forestry is a threat to the biodiversity and that many forest species will go extinct unless drastic ... -

(Master thesis, 2016-08-31)Ekstra fôring er eitt av fleire bevaringstiltak som har blitt brukt for å auke dyrs levedyktigheit. Supplerande fôring har hatt ulikt resultat basert på dyrs åtferd, intensitet og tilpassing av tiltak. Fjellrev er i Noreg ... -
Does the solitary bee Andrena lapponica show sex-specific responses to habitat change?
(Master thesis, 2017)Aim: Land use alterations are a serious challenge for solitary bees. This is especially so for specialized bees that rely on a single plant species when collecting pollen for their larvae. Moreover, the sex ratio within ... -
Does tunnel wash water have an impact on vital rates and displacement of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in river Årungselva
(Master thesis, 2021)Earlier studies on runoff water from roads and tunnels have demonstrated that such water hold toxic substances that can be harmful to aquatic biota. River Årungselva, which flows into the inner part of Bunnefjorden close ... -
