Allopatric speciation and multi-trait variation in the common chaffinch (Fringilla coelebs) complex (Master thesis / Masteroppgave, 2013)The common chaffinch (Fringilla coelebs) is a widespread passerine species in the West Palearctic, and is a common breeder in most of Europe, western Asia, northern Africa, and the Macaronesian islands in the Atlantic ...

(Master thesis / Masteroppgave, 2014)Heterozygosity is often shown to have a positive relationship with fitness-related characters. Sperm cells are fitness-related characters that show great variation among species, population's males and even within individual ...
-
(Master thesis / Masteroppgave, 2017)The evolutionary scaling of brain size on body size among species is strikingly constant across vertebrates, suggesting that the brain size is constrained by body size. Body size is a strong predictor of brain size, but ...

(Master thesis / Masteroppgave, 2020)As an effect of climate change and alterations in land use, the ranges of roe deer and also that of their ectoparasites, like the sheep tick (Ixodes ricinus) are expanding. This has also increased the occurrence of tick-borne ...
-
(Master thesis / Masteroppgave, 2015)Beak morphology is an ecologically important trait for birds. Beak size and shape are crucial for adapting to new niches and for optimal utilization of existing food sources. The adaptive potential of a species can be ...
-
(Master thesis / Masteroppgave, 2015)Hybridization is a common phenomenon within the genus Canis. The recently discovered African wolf (Canis lupaster), is sympatric with several closely related species; the Ethiopian wolf (Canis simensis), the side-striped ...

(Master thesis / Masteroppgave, 2014)As molecular and bioinformatics techniques are used more frequently and new marine habitats are analysed, a constant increase of marine fungal diversity has been reported, suggesting that marine fungi are a diverse but ...
-
(Master thesis / Masteroppgave, 2018)I present a model of chiasma interference and recombination in homo- and heterokaryotypes and a model of nonrandom mating. These two models form the basis of a general-purpose deterministic multilocus evolution simulator, ...

Climate change effects on substrate affinity and trait-dependent responses in wood-decomposing fungi (Master thesis / Masteroppgave, 2016)Climate change is the effect of rapid and recent change in global climate variables, affecting all species in all ecosystems. Fungi are no exception, fulfilling a variety of important roles as decomposers, parasites and ...
-
(Master thesis / Masteroppgave, 2015)Across the avian lineage, closely related species, or even populations within the same species may display differing migratory phenotypes. The many components of migratory behaviour are inherited as one migratory gene ...

Description of a new Upper Jurassic ophthalmosaurid ichthyosaur from the Slottsmøya Member, Agardhfjellet Formation of central SpitsbergenRestricted Access (Master thesis / Masteroppgave, 2013)Ichthyosaurs were a group of marine reptiles that thrived in the Mesozoic seas. They evolved to be highly specialized marine predators, and were the first reptilian group to be entirely aquatic. This project’s goal was to ...
-
(Master thesis / Masteroppgave, 2013)The ridge-snowbed gradient is of high importance in alpine areas in structuring the vegetation cover. However, to what degree belowground fungal communities are affected by the gradient is much poorer understood. In this ...

(Master thesis / Masteroppgave, 2016)Fragmentation of habitats is one of the major threats to biodiversity. Fragmentations will reduce connectivity and consequently affect the genetic population structure particularly in rivers. In the current study the genetic ...
