Distribution patterns of gymnosperms in Sakhalin and a comparison with those in the Kurils: newly proposed S-K index
Distribution patterns of nine species of gymnosperms native to Sakhalin and the Kuril Islands are analyzed quantitatively based on the examination of main Japanese herbaria. Pinus pumila and Larix gmelinii represent the most abundant species of gymnosperms in the regions. The Sakhalin-Kurils index (...

Distribution patterns of nine species of gymnosperms native to Sakhalin and the Kuril Islands are analyzed quantitatively based on the examination of main Japanese herbaria.
