Arctic ice no barrier for plants

clipped from news.bbc.co.uk Arctic ice no barrier for plants Arctic plant species can travel vast distances, researchers suggest Arctic plants are able to migrate the distances needed to survive changes to the climate, scientists have suggested. Habitats are expected to shift further north as the planet warms, and plants' inability to move quickly enough has been a cause for concern. But researchers, writing in the journal Science, suggest seeds can be carried vast distances by the wind and sea ice. The biggest challenge, they added, was likely to be their ability to establish themselves in the new habitat. Researchers from Norway and France analysed more than 4,000 samples of nine flowering plant species found on the remote Svalbard islands inside the Arctic Circle. By analysing the genetic fingerprints of the plants, the team reconstructed past plant colonization and decline in the area.
