University of Basel During the Ice Ages the European Alps were covered by a thick layer of ice. Climate fluctuations led to great changes in the occurrences of plants: They survived the cold periods in refugia on the periphery of the Alps which they then repopulated after the ice had drawn back. Such processes in the history of the earth can be detected by molecular analysis as "genetic fingerprints": refugia and colonization routes can be identified as genetic groups within the plant...

DNA evidence supports a coastal northeastern Atlantic glacial refugium for a boreal tree species Can a road-trip across eastern North America, ancient ice sheets, and DNA samples unlock the ancestral history of jack pine trees? Julie Godbout and colleagues from the Universit© Laval, Quebec, Canada, certainly hoped that driving across northeastern U.S. and Canada to collect samples from jack pine trees would shed some light on how glaciers may have impacted present-day pine genetics....
