(Master thesis / Masteroppgave, 2019)The genus Cochlearia, together with its sister genus Ionopsidium Rchb., forms the tribe Cochlearieae, a rather small tribe which comprises about 30 taxa, which either x=6 or x=7 basic chromosome number. The x=6 series forms ...

A new method to quantify the accuracy of classification and spatial delineation in land cover maps (Master thesis / Masteroppgave, 2018)Land cover maps provide spatial information on the physical cover of the earth. With increasing strain on natural resources, these maps enable knowledge-based nature management. Such maps represent a generalization of ...

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)Climate change is altering many aspects of local selection regimes. Which aspects of changing environments causing the strongest selective force, differ widely across species. Strong climatic and topographical heterogeneity ...

Assessing the flower visitation to soybean (Glycine max) and different sampling methods in an intensive agricultural system of the Argentinian PampasRestricted Access (Master thesis / Masteroppgave, 2017)
-
(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)Elettaria Maton is a small genus in the pantropical Zingiberaceae, comprising 11 species. Molecular data analyses have been widely used to reconstruct evolutionary history and to infer phylogenetic relationships, but to ...
-
(Master thesis / Masteroppgave, 2020)Ecosystems all over the world are affected by climate change, and especially so high latitude and altitude ecosystems. One consequence of global warming in Norway is an upward shift in the mountain birch forest line. A ...

(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 ...

(Master thesis / Masteroppgave, 2019)Black-headed Gulls are in rapid decline in Norway and is categorized as VU (Vulnerable) on the national Red List. The Norwegian population has decreased from 30 000 pairs around 1990 to just 7000 pairs in 2011. In the study ...
