-
(Master thesis / Masteroppgave, 2016)Primates habitats are being increasingly fragmented by human activities worldwide. The behavioural flexibility exhibited by vervet monkeys (Chlorocebus pygerythrus) is assumed to be crucial in the species ability to persist ...

-
(Master thesis / Masteroppgave, 2016)Fragmentation of habitats is one of the major threats to biodiversity. Fragmentations will reduce connectivity and consequently affect the genetic population structure particularly in rivers. In the current study the genetic ...
-
(Master thesis / Masteroppgave, 2014)Interspecific hybridization has intrigued evolutionary biologists since Darwin s time. New genetic combinations can arise from hybridization, leading to offspring sometimes able to adapt to different niches than their ...
-
(Master thesis / Masteroppgave, 2015)Juncus bulbosus Growth Experiment performed over 13 weeks to establish its response to anoxic conditions over root system. 20 of 40 plants were grown hydroponically with oxygen deprived water supplied to the root system. ...

Effects of marine protected areas and selective fishing on abundance, age and size structure of goldsinny wrasse (Ctenolabrus rupestris) populations.Restricted Access (Master thesis / Masteroppgave, 2015)Wrasse species went from having almost no commercial value in Norway, and not being fished, to a landing of 21.2 million individuals in 2014 with 11.68 million of these being goldsinny. This explosive growth in fishing ...

(Master thesis / Masteroppgave, 2015)A permanent landscape scale grazing experiment was established at Hol, Buskerud, in a lower alpine ecosystem with a recent history of rather low grazing pressure. Since 2002, nine sub-enclosures has been permanently subjected ...

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, 2017)In sexually reproducing taxa, normal sperm function is critical for successful reproduction, and pathogenic bacteria can prevent this. Thus, understanding the role of bacteria in ejaculates can have significant implications ...

(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 ...
