  8. Genetic structure and diversity of Sorghum bicolor at three geographical scales in Africa (2013) Masteroppgave
    Khalsa, Siri-Dharma Kaur (Biologisk institutt) 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 cu...
  9. Toxicity of various mycotoxins to immune cells in vitro, with focus on morphological and phenotypic changes (2013) Masteroppgave
    Wisbech, Cathrine (Biologisk institutt) ABSTRACT Mycotoxins is a unwanted contaminant on grain, corn and fruits and are reported to be found in increasing amounts also in processed food. There is an increasing focus on mycotoxins worldwi...
  10. Distinct turnover in fungal communities along an alpine ridge-snowbed gradient (2013) Masteroppgave
    Fang, Yao (Biologisk institutt) The ridge-snowbed gradient is of high importance in alpine areas in structuring the vegetation cover. However, to what degree belowground fungal communities are affected by the gradient is much poorer...
  11. Using 454 sequencing for exploring diversity, host specificity and tissue specificity of the fungal genus Galerina associated with four boreal mosses (2012) Masteroppgave
    Heimdal, Rune (Biologisk institutt) Bryophytes are a dominant vegetation component of the boreal forest, and an important part of the ecosystem, yet little is known about the microbial community associated with them. The aims of this th...

  13. Bio-optical estimates of primary productivity in scandinavian lakes (2012) Masteroppgave
    Thrane, Jan-Erik (Biologisk institutt) Introduction: The absorption of photons in the water column of a lake can generally be attributed to four main components: algae, dissolved organic matter (DOM), non-living particulate organic matter ...
  14. Nematode infestation in flatfish in the outer Oslofjord (2012) Masteroppgave
    Raamat, Karin (Biologisk institutt) Nematodes from 361 fish from 15 species were collected between August 2010 and March 2012 at Langøya and at Torbjørnskjær in the outer Oslofjord. The study focused on the infection levels of the three...
