Blowing in the Wind: Arctic Plants Move Fast as Climate Changes

From this article:

Between Norway and the North Pole lies Svalbard—an icy Norwegian archipelago known for glaciers, freezing winds and polar bears. Swallowed by glaciers until 10,000 years ago, the island chain remains dominated by ice that covers 60 percent of its surface. But in the rest, hardy Arctic plants like mountain avens and white arctic bell heather have staked out territory. And a new analysis of thousands of samples of nine species of these types of plants reveals that Svalbard has been colonized frequently and repeatedly from all directions as it warmed and froze over thousands of years, indicating that Arctic plants can keep up with climate changes.
