Abstract
Oribatid mite communities of moss and lichen were investigated at 12 different altitudes on the northern slope of Mt.Fujisan. Samples were taken at every about 100 m height from 900 m to 2,330 m above the sea level. Structures of the communities were compared with one another by the WHTETAKER'S Percentage similarity. In the subalpine coniferous forest (Abies-Tsuga forest), the oribatid mite communities were very similar to each other. A total of 80 species collected was classified into several groups according to their range of appearance. Several species groups of the oribatids were found to be closely connected with altitudes and plant communities. Oribatid community of Larix leptolepis shrub (2,330 m alt.) was quite peculiar in having Ametroproctus reticulatus as the most dominant species, while in 8 among 12 stations the most dominant species was Tectocepheus velatus.
