Martin Arne Svenning

Hoveddelen av aktiviteten er relatert til økologi og livshistorie hos resident og anandrom laksefisk, og knyttet nært opp mot forvaltning. God felterfaring, spesielt i arktiske strøk (Svalbard, Nord-Norge og Nord-Vest Russland). Forskningsaktiviteten involverer en kombinasjon av feltinnsamling, bearbeiding i laboratorium og teoretiske/statistiske analyser.

Torkild Tveraa

My main research focus is on population dynamics, demography and life history strategies. In this framework, I focus on the links between food limitation, climatic variation and predation.

Bård-Jørgen Bårdsen

• Population dynamics, demography and life history strategies with special focus on the relationship between food access, climate and reproduction for reindeer. • Theoretical biology and ecological methodology with special focus on the use of experiments, official statistics, models and monitoring. • Multidisciplinary research with special focus on biology (behavioural ecology), social science (anthropology) and quantitative methods.

Kari Elsa Ellingsen


The main part of my research activities is focused on biodiversity, including functional diversity. This involves the measurement and modelling of biodiversity, issues of spatial and temporal scales, drivers of change, such as, the impact of different types of human activities and climate change, as well as the impact of top predators on other ecosystem components, i.e. cumulative impacts. I am also interested in the potential for reversibility of changes. Much of the research done involves the use of large-scale and/or long-term datasets already collected in scientific surveys or environmental monitoring surveys. I have studied marine biodiversity in different parts of the world in shallow waters, on the continental shelf and in the deep-sea using data on benthos and fish assemblages, including a focus on the High North. Most of my research has been on marine ecosystems, but I am also involved in research related to other ecosystems. I am also focusing on environmental monitoring and study/sampling design. The work implies many national and international collaborations, e.g. with scientists from Europe, New Zealand, Canada, and Australia.

Børge Moe

Seabird ecology, arctic biology, ecotoxicology and ecophysiology. Moe is working with questions related to tracking of migration and distributions, energetics, stress, pollutants, life history and climate. Study species: kittiwake, common eider, arctic skua, long-tailed skua, glaucous gull, little auk, lesser black-backed gull, common guillemot, atlantic puffin, European shag, northern fulmar, herring gull, common gull, snow petrel, waders and some terrestrial bird species. Moe cooperates with many scientists from other national and international research institutes.
