(Master thesis / Masteroppgave, 2014)Reproductive barriers between diverging taxa are necessary for speciation to occur. Premating barriers are thought to be of especially great importance, such as plumage colour which is often used in species recognition and ...
-
(Master thesis / Masteroppgave, 2022)The major histocompatibility complex (MHC) genes are highly diverse in vertebrates and have demonstrated to yield a higher fitness with an optimal diversity that is neither too high nor too low. MHC based mate choice has ...
-
(Master thesis / Masteroppgave, 2023)The Major Histocompatibility Complex (MHC) is a group of closely linked loci that play an important role in the immune system within all jawed vertebrates, and it has been shown to yield a higher fitness with an intermediate ...

(Master thesis / Masteroppgave, 2015)The Black Death pandemic swept through Europe during the Middle Ages leading to high mortality from plague, caused by the bacterium Yersinia pestis. How the disease was transmitted in Europe is not fully elucidated, and ...

Molecular systematics of the lichen genus Eschatogonia (Ramalinaceae, Ascomycota)Restricted Access (Master thesis / Masteroppgave, 2017)I have addressed taxonomic affiliation, genus delimitation, and species delimitations in the lichen genus Eschatogonia. Preliminary parsimony analyses, based on one mitochondrial (SSU) ribosomal DNA-region, on a dataset ...

Multigenerational effects of diet and temperature on size and fitness associated traits in Daphnia (Master thesis / Masteroppgave, 2013)This thesis presents a synthesis of experimental studies with Daphnia, in a multigenerational perspective. The main goal of the thesis was to investigate the role of diet (phosphorous (P) limitation) and temperature (10 ...

Mycorrhiza and root-associated fungi of the ericaceous Arctic plant Cassiope tetragona after artificial warming and in the natural environmentRestricted Access (Master thesis / Masteroppgave, 2015)Mycorrhizal associations are essential to most plant life on earth. Cassiope tetragona is a circumpolar Arctic plant in the Ericaceae family, which has been reported to form ericoid mycorrhiza as well as ectomycorrhiza, ...

(Master thesis / Masteroppgave, 2020)Urban natur er lite forsket på sammenlignet med uberørt natur, men naturen i og rundt byene er viktig å ha kunnskap om for å kunne ta gode og bærekraftige avgjørelser i byplanlegging og vern av natur. Naturen i og rundt ...
-
(Master thesis / Masteroppgave, 2015)Nutrient availability is important for microbes in soil environments. When an animal dies and decomposes, nutrients are released into the soil. This may cause a shift in the diversity of microbes present, as well as lead ...
-
(Master thesis / Masteroppgave, 2014)Plant reproduction in the Arctic is challenging, and tight energy budgets, short growing season and the limited number of pollinators favour self-pollination. Self-pollination over time will, however, have a negative effect ...

(Master thesis / Masteroppgave, 2016)This thesis investigates the relationship between personality traits and natal dispersal for both sexes of the great tit Parus major in a population close to Oslo, Norway. Contrary to previous studies which focused only ...
