MSc from University of Tromsø in January 2001, biologist 2001-2004, PhD student at Department of Biology, UiT 2004-2009, post.doc. researcher AMB, UiT 2010-2013. Researcher at UiT since May 2013.


Forskningsinteresser

 

  • Tundra økosystemer under endrende betingelser, særlig effekten av klimaendringer og endrede beitedyrpopulasjoner
  • Mangfold av planter og beite, vegetasjonsmønstre, endringer i vegetasjonen, rollen av planter i terrestre, arktiske næringsnett
  • Overvåkning av arktiske, terrestre næringsnett


Forskningsprosjekter

Jobber med planlegging av Climate-ecological Observatory for Arctic Tundra (COAT).

Samarbeid:

 “Island-mainland plant communities: effects of species pool, grazing and productivity on spatial components of diversity” (project of prof. Ingibjörg Svala Jónsdóttir, University of Iceland). The general aim of this project is to analyse how plant species diversity is spatially organised in relation to selected factors, which are the size of regional species pools, grazing by large herbivores (reindeer and sheep), and contrasting productivity levels.

 “The effect of grazing on the biological silicon buffer in subarctic ecosystems” (project of PhD student Adriaan Smis UiT/University of Antwerp, Belgium). The aim of this project is to quantify Si pools and fluxes in subarctic tundra ecosystems and to study the effects of intensive grazing on the functioning of the biological Si buffer in selected vegetation types.

Tidligere prosjekt:

Ecosystem Finnmark (EcoFinn) - Ungulate overabundance, trophic cascades and subsidies

My research in the project Ecosystem Finnmark is focused on estimation of impacts of reindeer browsing on willow thicket spatial extent in conjunction with other environmental constraints. I also work with assessment of the role of willow thickets as foci and sources of biodiversity and trophic interactions.
