Ledum palustre s. lat., Vaccinium vitis-idaea and Vaccinium uliginosum represent the three most abundant species of the Ericaceae in the regions. Many Sakhalin-Kurils indices (S-K indices) of the species of the Ericaceae show negative numbers, and it reflects more predominant arctic-alpine "heath" tundras found in the Kurils than in Sakhalin. Most species with high positive S-K indices meaning a distribution bias toward Sakhalin, have the circumpolar or Northeast Eurasian distribution patterns. On the other hand, most species with low negative S-K indices meaning a distribution bias toward the Kurils, have the distribtuion patterns confined to Japan and its neighbors, or the North Pacific region.北海道大学総合博物館Hokkaido University Museum2006-03engdepartmental bulletin paperVoRhttp://hdl.handle.net/2115/478381348-169XAA11842183北海道大学総合博物館研究報告Bulletin of the Hokkaido University Museum3139https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/47838/1/v.%202-1.pdfapplication/pdf4.75 MB2006-03
