(Master thesis / Masteroppgave, 2013)Host specificity among ectomycorrhizal (ECM) fungi seems to vary among different habitats, and it is difficult to draw general conclusions across environments. Little is known about the host specificity among arctic ECM ...
-
(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, 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 ...

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 environmentBegrenset tilgang (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, 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 ...

(Master thesis / Masteroppgave, 2014)Polyploidy and ecotypic differentiation are important aspects of plant evolution. The present study has applied molecular methods to investigate the polyploid origin and ecotypic differentiation of the tetraploid Cochlearia ...

(Master thesis / Masteroppgave, 2016)The regular movement of animals between summer and winter ranges, termed seasonal migration, is a common phenomenon among ungulates at northern latitudes. The most prominent hypothesis to explain seasonal migration is the ...
-
(Master thesis / Masteroppgave, 2015)Animal personality can be defined as individual behavioural differences that are repeatable and consistent across time and/or contexts. In the model species great tit Parus major, studies on personality have shown consistent ...
-
(Master thesis / Masteroppgave, 2015)Repeatable behavioural variation within individuals that is consistent over time and across contexts is often defined as non-human animal personality. Individuals may be classified as having a shy or bold personality. Shy ...

(Master thesis / Masteroppgave, 2014)Phenotypic plasticity allows organisms with identical genotypes to develop different phenotypes in response to different environmental cues. Phenotypic plasticity is a trait in itself, and can be either adaptive or ...
