PhD project title:

Reinforcement and phylogeny in Fucus species.

PhD project description:

The project will look at the ‘speciation continuum’ in the brown algal genus Fucus and will identify molecular mechanisms of speciation in two sister species. Hybrid zones between the two species Fucus distichus and Fucus serratus provide a unique situation to examine mechanisms of reinforcement, adaptation and speciation at a molecular level. I will use Next-Generation Sequencing of transcriptome libraries to better understand the molecular basis of speciation and its effect on biodiversity and adaptation in these ecologically important marine macroalgae.

Start date: September 2016

Research interests:

  • Ecology and bioenergetics of pelagic, sympagic (ice-associated) and hard-bottom invertebrates and fishes in Arctic marine environments
  • Marine ecosystem structure (stable isotopes), energy flow (lipids), and bioaccumulation of persistent pollutants in Arctic marine food webs
  • Integration of physical and biological data in multidisciplinary research projects carried out in the Marginal Ice Zone (MIZ) and fjords in Svalbard

My experience includes >25 years of Arctic research, both experimental and field based work. I have organized multidisciplinary research programs and cruises, and participated on these as researcher, scientific diver and cruise leader. I have published 113 papers in the peer-reviewed literature, including many multidisciplinary papers. I also have extensive teaching experience as course instructor, lecturer and external examiner at the university level, and am external supervisor for graduate students. I have organized and led workshops and sat on review panels for international research proposals. I have lead international groups for establishing new marine research projects and a new Arctic Marine Laboratory in Ny-Ålesund. I am currently leading marine ecological studies in ICE – Centre for ice, climate and environment.

Running national and international projects:

  • MOSJ-ICE-project to determine inter-annual variation in hydrography and pelagic plankton in Kongsfjorden and Rijpfjorden in Svalbard (NPI)
  • N-ICE2015 participation in the Arctic Ocean with dive team to determine under-ice flora and fauna (NPI)
  • Ice-algal and under-ice phytoplankton bloom dynamics in a changing Arctic icescape (Norwegian Research Council)

Completed national and international projects:

  • Kongsfjorden Ecosystem – new views after more than a decade of research (NRC)
  • Impact of ocean acidification on Arctic zooplankton populations (NRC)
  • Response of marine and terrestrial ecosystems to climate changes in Arctic – links between physical environment biodiversity of zooplankton and seabird populations (ALKEKONGE) (Polish-Norwegian Research Fund)
  • Marine ecosystem consequences of climate induced changes in water masses off West-Spitsbergen (MariClim) (NRC)
