Abstract

Nakagoshi, N. 2013. A note on hierarchical approaches to vegetation science. Hikobia 16: 315-xxx.

Existence of plant community is confirmed by the biological dynamics from gene to association levels. There are several approaches to find rules of species composition, habitat and history of plant communities. In Japan, diversified level investigation technologies have been applied to select plant communities, and in this note, the communities with Ericaceae species are particularly focused. Rhododendron ripense is a characteristic species of a riparian shrub community. Using genetic and molecular approaches, the establishment, in the Pleistocene can be clarified, and distribution and colonization of R. repense community from east to west Honshu, Shikoku and Kyushu will also be explaned. In addition, R. macrosepalum growing in the dry land is presumed as the origin of R. ripense. Various data helped interpret that within the territory of R. indicum community in riparian rocky habitat, R. ripense competitively invaded into the space and established its own community. All 6 associations/communities in Pinion densiflorae have different dominant species of Rhododendron in the shrub layer under Pinus densiflora canopy. These six Rhododendron species have been reducing their dominance rapidly. Vegetation scientists have found that Ericaeae species are essential components of the associations in subalpine conifer forest and alpine vegetation classes in Japan, however current climate change has been deteriorating the habitat of the communities with Ericaceae. It is feared that the associations will extinct in the near future.
