(Master thesis / Masteroppgave, 2007)Ornithomimosaurs are only one out of several dinosaurian groups that at some point evolved beaks. The morphology of this beak and its relation to dietary habits have long been debated.Birds and turtles are the primary ...
-
(Master thesis / Masteroppgave, 2008)Oviraptorids are one of several groups of dinosaurs which have evolved beaks. Of extant beaked animals, birds and turtles are the best known. In this study, an anatomical comparison between oviraptorids, extant birds and ...
-
(Master thesis / Masteroppgave, 2007)Climatic fluctuations characterized the climate in East Africa during the Plio-Pleistocene. These variable conditions established opportunities for ecological fragmentation with subsequent genetic isolation of species ...
-
(Master thesis / Masteroppgave, 2012)Nearly one third of the vascular plant species of the remote high arctic archipelago of Svalbard are listed on the regional Red List for Svalbard, and there is a need for information to evaluate their conservation status, ...
-
(Master thesis / Masteroppgave, 2007)A Moroccan polycotylid plesiosaur from the early Turonian (Upper Cretaceous) of the Goulmima Formation is described. The specimen, bought from an American fossil dealer in 2002 by the Museum of Natural History, Oslo, is a ...
-
(Master thesis / Masteroppgave, 2008)Adaptation to different foraging resources is believed to be an important driving force of divergence between populations. Following colonization of freshwater, threespined sticklebacks (Gasterosteus aculeatus) have occupied ...
-
(Master thesis / Masteroppgave, 2010)Fungal endophytes have been shown to be extremely widespread and abundant in terrestrial plants. It is also known that fungal endophytes may affect the grazing intensity of the host plant. In this study the occurrence of ...
-
(Master thesis / Masteroppgave, 2012)Bale-apen (Chlorocebus djamdjamensis) er en lite kjent, endemisk primat fra det etiopiske høylandet. Apen er klassifisert som "Vulnerable" under IUCNs Rødliste for truede arter, og er truet av et stadig økende antropogent ...
-
Epirrita autumnata (Lepidoptera, Geometridae): one diverse species or a complex of several cryptic species?Restricted Access (Master thesis / Masteroppgave, 2010)Preliminary results from DNA-barcoding of Scandinavian butterflies and moths show high intraspecific sequence differences in the Autumnal moth, E. autumnata. One theory that might explain this finding is that E. autumnata ...
-
(Master thesis / Masteroppgave, 2006)Introduced plant species may lead to negative consequences for the local community by outcompeting other species, and in extreme situations decrease biodiversity. It is well known that once an invasive species becomes ...
-
Evolutionary studies of uncultivated Radiolaria and their symbionts using Single Cell Whole Genome AmplificationRestricted Access (Master thesis / Masteroppgave, 2010)Understanding the evolution of eukaryotes and resolving the Tree of Life is one of the major goals of biology. Protists (unicellular eukaryotes) play a crucial role in this quest being the earliest diverging eukaryotes and ...
-
(Master thesis / Masteroppgave, 2006)Fluctuating asymmetry (FA) as a measure of environmental stress was studied in polar bear (Ursus maritimus) skulls from East Greenland (n = 300, collected during the period 1892-2004) and Svalbard (n = 391, collected during ...

The fungal community associated with roots of alpine and arctic Dryas octopetala along a latitudinal gradientRestricted Access (Master thesis / Masteroppgave, 2009)The ectomycorrhizal (ECM) dwarf shrub Dryas octopetala is one of the hardiest and most abundant of all woody plant groups in alpine and arctic environments. The main aim of this study was to characterise the fungal communities ...
-
(Master thesis / Masteroppgave, 2008)The control region (CR) of the mitochondrial DNA has been previously used to decipher the population structure of Holocene bowhead whales (Balaena mysticetus) from the Spitsbergen stock. The bone samples dated from recent ...
-
(Master thesis / Masteroppgave, 2009)Abstract Previous studies have revealed increased levels of germline mutations in minisatellite DNA in populations of herring gulls and mice sampled in Hamilton Harbour, Ontario Canada, an industrial area with high emissions ...
-
(Master thesis / Masteroppgave, 2007)Numerous scientific investigations have been undertaken to answer the question of Polynesian origins. Most archaeological and linguistic evidence and previous studies in population genetics suggested that Remote Oceania ...
-
(Master thesis / Masteroppgave, 2007)Summary. This work arose from a collaborative project between the University of Western Cape and the University of Oslo, funded by the Research Council of Norway. The original project was set up to identify informative ...
-
(Master thesis / Masteroppgave, 2011)Environmental variables and epiphytic lichen flora of 279 deciduous rich bark trees of a boreonemoral rainforest in the oceanic region of Western Norway were studied. The lichen flora from base to breast height of the tree ...

Migration patterns and taxonomy of Dryas octopetala L. in the North Atlantic regionRestricted Access (Master thesis / Masteroppgave, 2010)The climatic fluctuations of the Quaternary have greatly influenced the distribution, composition and genetic structure of plant populations. Dryas octopetala sensu lato is an arctic-alpine plant belonging to a circumpolar ...
