Jarle Werner Bjerke

  • Research on climate effects, especially related to climate change and extreme weather events in boreal and Arctic areas;
  • Experimental studies for providing baselines for modeling og on-going and future ecosystem change due to climate change;
  • Grazing ecology, especially related to effects of reindeer and goose;
  • Anthropogenic effects, especially changes in land use (e.g. afforestation, industry, reduced outfield grazing) and air pollution, plus indirect effects via climate change, as listed above;
  • Evaluations of biological diversity
  • Taxonomy and systematics, especially on some lichen genera
  • Impact assessments prior to planned land use changes.

Jane Uhd Jepsen

Ecologist with expertise in northern populations and ecosystems, in particular plant-herbivore interactions in sub-arctic birch forests and the forest-tundra ecotone. Among my main interests are studies of the spatio-temporal dynamics of outbreaking geometrid moth species, effects of insect outbreaks on forest ecosystems and ecological monitoring. I am an experienced used of GIS, R and remote sensing in population and landscape studies.

Erik Framstad

Main scientific experience covers population and habitat ecology of small mammals in boreal forests and mountain ecosystems. Applied research and consultancy work includes studies and assessments of boreal forest ecology, protected areas, ecological effects of agriculture and forestry on species and ecosystems, environmental impact assessments of infrastructure development projects, as well as assessments, indicators and monitoring of terrestrial biodiversity.

Main administrative experience covers management of NINA's research department in Oslo over > 25 yrs, as well as coordination of terrestrial ecosystem monitoring and major research projects and programmes on boreal forests or cultural landscapes.
