Pre-adaptation of Arctic plants to climate change.
Re-appraisal of high latitude ice cover during the Weichselian and the recent discovery of pre-Holocene plant communities in Novaya Zemlya and Northern Norway suggests that the contemporary Arctic flora may have had a longer time span in its occupation of high latitude sites than has hitherto been r...

Re-appraisal of high latitude ice cover during the Weichselian and the recent discovery of pre-Holocene plant communities in Novaya Zemlya and Northern Norway suggests that the contemporary Arctic flora may have had a longer time span in its occupation of high latitude sites than has hitherto been recognised. The present-day Arctic flora in some regions may therefore have derived at least some of its genetic inheritance from populations that survived in ice-free refugia in the high Arctic polar deserts during the latter stages of the Weichselian glaciation.
