Abstract |
|
The Holocene Hypsithermal Interval(or climatic optimum) was the warmest post-glacial period: temperatures rose to as much as 1-4oC above present temperatures. We hypothesize that southern plants expanded northward and upward during the Hypsithermal Interval. The Hypsithermal relict populations are defined as populations which distribute mainly in Is. Cheju and Southern subregions and have populations of short-distance dispersion separated by more than 100 km from the nearest distribution. The Hypsithermal relict species were identified and their distributions were mapped based on botanical floras and checklist, herbaria specimens, ecological studies, and field surveys of selected species. Evaluation of the hypothesis was based on reviews of published pollen stratigraphic and paleoecological studies. The results showed that the Holocene Hypsithermal relicts such as Corylopsis coreana Uyeki, Carpinus turczaninowii Hance, Stewartia koreana Nakai ex Rehder were expanded northward during the Holocene Hypsithermal Interval. |
