Research interests
Arctic botany and bioclimatology
My research interest was previously focused on arctic botany and bioclimatology. I have made reviews on the vegetation types of Svalbard (Elvebakk 1994), produced a catalogue of all known botanic species in Svalbard (Elvebakk & Prestrud 1996), and presented a coarse-scale vegetation map of Svalbard (Elvebakk 2005). I was also an active member of the group led by S.A. Walker producing the Circompolar Arctic Vegetation Map, and the map of bioclimatic zones presented there is mainly based on Elvebakk et al. (1999), with names of these zones are from Elvebakk (1999). I also developed, together with students, a new method for producing bioclimatic maps on a local scale, like studies from East Greenland (Karlsen & Elvebakk 1995) and Finnmark (Karlsen et al. 2005). During the last decade fewer publications have been written on arctic topics, however, Elvebakk & Karlsen (2022) presented a new and detailed bioclimatic subdivision of Finnmark and Karlsen et al. (2024) showed how Svalbard is greening as a result of the ongoing Climate Change.
Taxonomy of Pannariaceae lichens on a global scale
During the last 20 years this has gradually turned into a major research interest. Lichens previously cathegorized within the genera Psoroma and Pannaria have now turned out to be much more diverse, and together with cooperation partners, Soon Gyu Hong from the Korean Polar Resarch Institute in particular, we have now split out five new genera from these previously too widely defined genera. This group is most interesting on a global scale as its ancestors probably had diversified into austral and non-austral groups already by the Cretaceous. Then the austral group evolved further into two polar-alpine clades (brown psoromas) following the isolation and cooling of Antarctica at 34 Ma adapting to the new tundra-like habitats. With more recent orogenies, this group migrated northwards along mountains of the Americas during the last ice age, and established a well-known bipolar element, which is now being studied in more detail by us. Other migration waves resulted in additional alpine taxa in Australasia and South Africa.
The large genus Pannaria s.l. apparently had an evolutionary origin centered in New Zealand, where many new species still are being discovered among all subgroups, whereas there are small sister genera in South America with a stagnated evolution. Two large groups have conquered all temperate to tropical areas of the earth, and have probably an origin among austral groups, but have lost their green algal partner, whereas one small one has become polar-alpine. About 30 new species within the family have been described so far by us, in addition to other taxonomic treatments.
Further studies focusing on the genera Psoroma and Pannaria including phylogeny, in particular contributed by the cooperation partner Soon Gyu Hong of the Korean Polar Research Institute, are planned as the major scientific contribution during the period to come. See list of publications and presentations attached below.
Vascular plant taxonomy on poppies
I have dealt with quite a number of lichen groups also outside of Pannariaceae, in addition to vascular plant studies related to my job in Tromsø Arctic-Alpine Botanic Garden, including revisions in the South American genus Calandrinia (Elvebakk et al. 2015). A last project initiated during my work in the Garden was a large review paper on Papaver and related poppy genera primarily in Eurasia (Elvebakk & Bjerke 2024). This has led to ongoing taxonomic studies on a group of alpine poppies distributed in the northern part of the Middle East and Caucasia.
By 2022 I had 63 author citations in the Web of Science Core Collection.

Teaching
Previously, I had a lot of teaching and supervision of students (4 dr. students, 14 master students), however, since 2006, teaching duites have been replaced by leading the Garden, and now I only have marginal teaching activities.
Member of research group / centre
CV
I was born in Lødingen, North Norway in 1951, and after studies at what is now the NTNU University in Trondheim I was employed at UiT in 1979. During almost three decades I was in a teaching and research position at the former Dept. of Biology, now Dept. of Arctic and Marine Biology. As outlined below ‘Research Interests’, my profile then was on arctic botany and bioclimatology, based on extensive field work in Svalbard, partly also in Canada and East Greenland. I participated in various Arctic research networks.
In 2006 I moved to Tromsø University Museum, first with an overlap period, to a new position as leader of Tromsø Arctic-Alpine Botanic Garden. Leaving the peak garden season for Arctic field work became more problematic, and in a museum collection context, taxonomy appeared more relevant than ecology. An already initiated project on taxonomy of a lichen group expanded, due to a series of exciting discoveries. Field work could then take place during our winter in the Southern Hemisphere, where the group has its centre. Their evolutionary processes appear to be linked to most of the important geological events during the earth’s 100 Ma years or so, and the Pleistocene ice ages brought representatives also to our part of the world. My project with cooperation partners now aims to describe new species and redefine existing ones as an aim in its own, but also as pieces of a puzzle in an attempt to reconstruct patterns in its evolutionary history, which is a very exciting one.
For more details, see formulation on research interests.
From 2023 onwards I plan to be a in a prof. emeritus position and continue my research interests.
