Master thesis - Biogenic volatile organic compound emissions from Subarctic hos Københavns Universitet

Biogenic volatile organic compound (BVOC) emissions from high-latitude ecosystems and factors driving emissions of BVOCs within mountain birch.

Biogenic volatile organic compounds (BVOCs) are a large and diverse group of molecules released from plants into the atmosphere. BVOCs participate in direct and indirect plant defence against biotic and abiotic stressors. Some of the functions include: attracting pollinators and insect predators, deterring insect herbivores and pathogens, and plant - plant communication. Furthermore, BVOCs are highly reactive and can affect the physical and chemical properties of the atmosphere.

The main aim of this project will be to link the BVOC emissions from high-latitude ecosystems with factors that might affect the emissions within species, for example, genotype, tree age, insect herbivory, or past stresses plants have experienced (e.g. insect herbivory outbreaks).

Ultimately, these parameters will be implemented into global BVOC models to test whether the new parameters improve the current and future BVOC emissions.

Student can choose to focus on genetics, dedroevology, and/or herbivory effects on BVOCs.

The student will participate in the fieldwork in one or several locations:

  • Dovrefjell, Norway
  • Tromsø, Norway
  • Abisko, Sweden

Student will also have a co-supervisor and collaborators from Norwegian Unviersity of Science and Technology (Professor James D.M.Speed and Associate Professor Kristine Bakke Westergaard). Depending on the topic student can have an opportunity to conduct laboratory work at the Norwegian University of Science and Technology.
