Where did the northern peatland species survive the dry glacials: cloudberry ( Rubus chamaemorus) as an example
Abstract Aim During the last ice age large parts of the north boreal and subarctic zones were covered by ice, while the climate in ice‐free regions of northern Asia was extremely cold and dry. The extensive peatlands of these zones with their characteristic vegetation developed at the beginning of t...
