The influence of food access on spermatophore production in the pelagic copepod, Temora longicornis (Master thesis / Masteroppgave, 2013)In studies on reproductive ecology of pelagic copepods, the role of males is often neglected and male reproductive investment is not well understood. Lately there has been an increasing interest in the topic and it has ...

Er avvikende celler av Prymnesium polylepis mer motstandsdyktige mot virusangrep enn typiske celler? (Master thesis / Masteroppgave, 2014)Prymnesium polylepis er en svepeflagellat med to ulike morfologiske flagellatstadier som består av avvikende eller typiske celler. Kulturer med typiske celler er haploide, og kulturer med avvikende celler kan enten være ...

Protists in the intestinal content of Atlantic cod (Gadus morhua L.), with a special emphasis on two parasite groups; the X-cell and Mesomycetozoa.Begrenset tilgang (Master thesis / Masteroppgave, 2015)Protists have representatives in all but one of the kingdoms in the tree of life and are highly important in the oceans, where they generate most of the carbon-flow in the first trophic levels. Parasitic lineages work as ...
