Long-distance plant dispersal to North Atlantic islands: colonization routes and founder effect
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-15)
Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic founder effect on five islands is associated with dispersal distance, island size and species traits. Most species colonized postglacially via multiple dispersal events from several ...
The role of sea ice for vascular plant dispersal in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09)
Sea ice has been suggested to be an important factor for dispersal of vascular
plants in the Arctic. To assess its role for postglacial colonization in the
North Atlantic region, we compiled data on the first Late Glacial to Holocene
occurrence of vascular plant species in East Greenland, Iceland, the Faroe
Islands and Svalbard. For each record, we reconstructed likely past dispersal
events ...
Circumpolar Arctic vegetation: a hierarchic review and roadmap toward an internationally consistent approach to survey, archive and classify tundra plot data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-10)
Satellite-derived remote-sensing products are providing a modern circumpolar perspective of Arctic
vegetation and its changes, but this new view is dependent on a long heritage of ground-based
observations in the Arctic. Several products of the Conservation of Arctic Flora and Fauna are key to
our current understanding.Wereview aspects of the PanArctic Flora, the Circumpolar Arctic
Vegetation ...
Postglacial species arrival and diversity buildup of northern ecosystems took millennia
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)
What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across
16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete
DNA and trait databases. We show that postglacial arrival time varies within and between plant growth forms.
Further, arrival times were mainly predicted by adaptation to temperature, ...
