A systems biology approach to integrated molecular analysis in pancreatic and periampullary adenocarcinoma
(Doctoral dissertations at the University College of Southeast Norway;2, Doctoral thesis, 2016-04-13)Pancreatic and periampullary adenocarcinoma (PA) is a highly lethal disease, for which the mortality rate closely parallels the incidence rate. Most of the PA patients remain asymptomatic until the disease reaches an ... -
Ecology of Alpine Lichen Heaths: Relationships Between Vegetation, Soil Temperature, and Edaphic Factors in Southern Norway
(Doctoral dissertations at the University of South-Eastern Norway;29, Doctoral thesis, 2019-03-01)Alpine lichen heaths are found on nutrient-poor and deep soils in the mountain plateaus in southern Norway. These are generally characterized by terricolous or so-called “mat-forming” lichens dominated by those in the ... -
Mercury in freshwater biota in southeastern Norway, with special emphasis on potential antagonistic effects of selenium on mercury bioaccumulation
(Doctoral dissertations at the University College of Southeast Norway;23, Doctoral thesis, 2017-10-06)Mercury (Hg), and in particular methylated Hg (methyl-Hg, MeHg), because of its high potential for bioaccumulation and biomagnification in aquatic food webs, generate health risks to both aquatic top predators and humans ... -
Mercury pollution in fish and invertebrates in natural and wildfire impacted lakes in Norway
(Doctoral dissertations at TUC;2014:8, Doctoral thesis; Peer reviewed, 2014-11-14)Mercury (Hg) contamination in fish has become a global issue and remains a major problem of concern in the Nordic countries, with atmospheric long-range transport of Hg being the main source to aquatic ecosystems. Most Hg ... -
Natural and human-induced impacts on the genetic structure of Eurasian reindeer
(Doctoral dissertations at the University College of Southeast Norway;11, Doctoral thesis, 2017-03-17)Geografisk variasjon hos arter og populasjoner er basert på genetisk variasjon, som videre er grunnleggende for naturstyrt evolusjon. Genetisk variasjon og struktur er styrt av faktorer som mutasjoner, seleksjon og genetisk ... -
Observing animal behaviour and movement patterns remotely: A case study using bio-logging technology on free-ranging Eurasian beavers (Castor fiber)
(Doctoral dissertations at the University College of Southeast Norway;10, Doctoral thesis, 2017-02-24)Understanding animal behaviour is a fundamental part of biology and has been revolutionized by the invention of bio-logging units, which can be used to study wild animals in their natural habitats. In this thesis, tri-axial ... -
Territoriality and life history strategies of the Eurasian beaver
(Doctoral dissertations at the University College of Southeast Norway;24, Doctoral thesis, 2017-09-29)We studied life history strategies in the Eurasian beaver (Castor fiber), a territorial, monogamous, long-lived mammal, to increase our understanding of the mechanisms and trade-offs affecting the onset of natal dispersal, ... -
The effect of training intensity, age and diet on aerobic capacity and metabolic risk factors: testing procedures and training interventions
(Doctoral dissertations at the University College of Southeast Norway;13, Doctoral thesis, 2017-04-21)BACKGROUND: Low cardiorespiratory fitness (CRF) with accompanying metabolic risk factors such as overweight/obesity, reduced blood glucose control, elevated blood pressure, and dyslipidemia, is one of the most important ... -
The effects of harvest on the sociospatial and genetic structure of a solitary-living large carnivore, the brown bear Ursus arctos
(Doctoral dissertations at the University College of Southeast Norway;28, Doctoral thesis, 2017-10-20)Understanding the effects of harvest is integral for sustainable wildlife management and conservation. And yet, the focus of managers has predominantly been on the direct mortality of harvest, often ignoring the indirect ... -
The importance of snow for mountain vegetation in the Hardangervidda area (Southern Norway): plant distribution, plant phenology, plant diversity, and effects of global climate change
(Doctoral dissertations at TUC;2013:4, Doctoral thesis; Peer reviewed, 2013-06-21)Snø er en av de viktigste faktorene for fjellvegetasjon. I fjellet forårsaker den varierende topografien og dens interaksjon med klimatiske faktorer en ujevn fordeling av snøen. Fordeling av snø og snøsmeltingsmønsteret ...
