Effekt av temperatur og fosforkonsentrasjon på celle- og genomstørrelse av Chlamydomonas reinhardtii (Master thesis / Masteroppgave, 2014)Temperatur og fosforkonsentrasjon spiller inn på cellesyklus til C. reinhardtii. Ikke-synkron cellesyklus gjør størrelsesendringer vanskelig å detekterer. Mulig genomstørrelse endring som følge av reallokasjon av P fra DNA ...

(Master thesis / Masteroppgave, 2019)Dracocephalum ruyschiana is a rare species in Europe and its conservation is considered a priority by the Norwegian Environment Agency. Specialist species in fragmented and rare habitats such as dry, calcareous grasslands ...
-
(Master thesis / Masteroppgave, 2022)Precise and accurate information about population numbers is crucial within wildlife ecology, for example, to effectively manage disease threats. After chronic wasting disease was detected in a reindeer (Rangifer tarandus) ...

(Master thesis / Masteroppgave, 2021)Her presenteres en analyse av 37 vertebrae, 1 komplett humerus og 7 brukne humeri fra små ichthyosaurer fra Tidlig Trias i Nedre Saurie-laget i Vendomdalenleddet fra Vikinghøgdaformasjonen, Marmierfjellet, Spitsbergen og ...
-
(Master thesis / Masteroppgave, 2019)Human activities have historically influenced the evolution of other species. Dramatic modifications in land-use and extreme urbanization have increased not only the amount of species associated with human environments, ...
-
(Master thesis / Masteroppgave, 2015)Hybridization is increasingly recognized as a source of novel variation, but how hybridization can contribute to evolution is still not fully understood. Insights into the evolutionary potential of hybrid species, and the ...

(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 ...
