(Master thesis / Masteroppgave, 2015)Fisheries activities and the development of more efficient fishing gear, have had detrimental effects in commercial stocks. This occurs largely as a result of negative selection acting on certain individuals during the ...

-
(Master thesis / Masteroppgave, 2020)The effect of elevated CO₂ on plant stoichiometry has been given a lot of attention in the last years; however, extended studies on the effects of elevated light added to the increased CO₂ are still insufficient. Plant ...
-
(Master thesis / Masteroppgave, 2019)In aquatic environments predator threats can be present as chemical cues which can induce defensive traits in prey. Such predatory induced cues can be responsible for changes in morphology, life histories and behavior. ...

(Master thesis / Masteroppgave, 2013)The dry rot fungus Serpula lacrymans is known as one of the most aggressive fungal house invaders in temperate regions. Recent genetic and phylogeographic studies have shed light on the distribution, colonisation and ...

(Master thesis / Masteroppgave, 2020)Character displacement has been a process discussed by biologist ever since Darwin visited the Galapagos in the 19th century. Similar species occurring together will sometimes diverge in characters to avoid hybridization ...

(Master thesis / Masteroppgave, 2019)In the Arctic tundra several different species of herbivores co-exist, with potentially large effects on tundra ecosystem functions and dynamics. Understanding the herbivores trophic interactions therefore provides essential ...

(Master thesis / Masteroppgave, 2022)Den økende populariteten til sanking har gjort at tradisjonell kunnskap (TEK) om sanking i Norge nå blir diskutert gjennom mange steder, inkludert litteratur, litteratur på nettet, sosiale medier og in situ kurs. Bruken ...

(Master thesis / Masteroppgave, 2021)Freshwater systems are important for a wide variety of organisms. With the addition of increased mean temperatures, increased frequency of extreme weather events and changes in precipitation patterns brought upon by climate ...
-
(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, 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 ...
