Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ... -
Horizon scanning of potential new alien vascular plant species and their climatic niche space in the Arctic
Ulsted, Tor Henrik (Master thesis, 2024)Biologiske invasjoner utgjør en eskalerende trussel mot Arktis grunnet økt menneskelig aktivitet og klimaendringer. Denne studien benyttet datadrevet horisontscanning for å identifisere potensielle nye fremmede karplanter ... -

Moving out of town? The status of alien plants in high‐Arctic Svalbard, and a method for monitoring of alien flora in high‐risk, polar environments
Bartlett, Jesamine; Westergaard, Kristine Bakke; Paulsen, Ingrid M. G.; Wedegärtner, Ronja Elisabeth Magdalene; Wilken, Florian; Ravolainen, Virve (Peer reviewed; Journal article, 2021)1. Rising human activity in the Arctic, combined with a warming climate, mincreases the probability of introduction and establishment of alien plant species. While settlements are known hotspots for persistent populations, ... -
Population genomic evidence for plant glacial survival in Scandinavia
Westergaard, Kristine Bakke; Zemp, Niklaus; Bruederle, Leo P.; Stenøien, Hans K.; Widmer, Alex; Fior, Simone (Journal article; Peer reviewed, 2019)Quaternary glaciations have played a major role in shaping the genetic diversity and distribution of plant species. Strong palaeoecological and genetic evidence supports a postglacial recolonization of most plant species ... -

John B.; Westergaard, Kristine Bakke; Birks, Hilary H; Lenoir, Jonathan (Journal article; Peer reviewed, 2017)In the face of climate change, populations have two survival options − they can remain in situ and tolerate the new climatic conditions (“stay”), or they can move to track their climatic niches (“go”). For sessile and ... -
