(Master thesis / Masteroppgave, 2023)An understanding of the behavior and habitat preferences of Greater Flamingos is crucial for the conservation of this species. The population of these birds is intricately connected to variations in the limnic habitat and ...
-
(Master thesis / Masteroppgave, 2013)The main objective of the present study is to describe and compare the morphology of the female genitalia within a selected number of species and families of the lower Diptera. The results are presented as two papers with ...
-
(Master thesis / Masteroppgave, 2013)Speciation involves the evolution of reproductive barriers that maintain the genetic integrity of species. Premating barriers, in particular, have been referred to as one of the most important mechanisms in keeping species ...

Fine-scale spatial structure of root-associated fungi within a single plant root systemRestricted Access (Master thesis / Masteroppgave, 2014)Ectomycorrhiza (ECM) is an ancient and prevalent symbiosis between plants and fungi, and is crucial for growth and survival for a number of plants. Host plants can form ECM with multiple fungi, yet little is known about ...

-
(Master thesis / Masteroppgave, 2021)Camera trapping is an increasingly important tool in animal ecology that is generally targeted towards large mammals, and especially large carnivores. Nonetheless, the cameras are triggered by all large and medium-sized ...
-
(Master thesis / Masteroppgave, 2017)Insect pollination is an important contribution to wild ecosystems in Norway and 80 % of plants seem to benefit from this important ecosystem service. During the last century, there has been an overall decline in pollinators, ...
-
(Master thesis / Masteroppgave, 2019)Seabirds bring substantial amounts of nitrogen (N) and phosphorous (P) from sea to their breeding colonies. On Svalbard, previous research has focused on the ornithogenic fluxes from sea to land, but little is known of the ...

-
(Master thesis / Masteroppgave, 2015)Arabidopsis thaliana has proven to be an extremely useful model organism in studies of plant biology and an extensive base of knowledge has been amassed of the diverse molecular processes in this plant. The next step is ...
-
(Master thesis / Masteroppgave, 2019)The INFLORESCENCE DEFICIENT IN ABSCISSION (IDA)/IDA-LIKE gene family encodes peptides hypothesized to be involved in different cell-separation events in plants. A phylogenetic analysis was performed to elucidate the ...
-
(Master thesis / Masteroppgave, 2014)European grayling from a common-gene pool and with a known ancestry were released into headwaters of a river system in Lesja, Oppland, Norway, about a century ago. These grayling dispersed downstream, and as a result there ...
-
(Master thesis / Masteroppgave, 2013)Sorghum is ranked the fifth most produced food crop in the world, and is a dietary staple for over 500 million people in over 30 countries. It is the second most produced food crop in Africa, where cultivation of local ...
-
(Master thesis / Masteroppgave, 2015)Section Cochlearia (Brassicaceae) includes highly polymorphic species complexes with regard to ploidal level, ecological adaptation and distribution. Low levels of chloroplast DNA divergence suggest that taxa most likely ...
-
(Master thesis / Masteroppgave, 2015)Various stressors such as higher temperatures, grazing by sea urchins, and anthropogenic effects may threaten kelp forests around the world. Conservation efforts can benefit from an understanding of current and historic ...

(Master thesis / Masteroppgave, 2018)
-
(Master thesis / Masteroppgave, 2015)Hybridization is an important evolutionary force. It may lead to the formation of new, adaptive genotypes, or even the formation of a new species. However, it also may lead to replacement, or merging of species. Hybridization ...
-
(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 ...
