Hakkoda-san, Mt. Iwate-san and Mt. Akita-Komagatake in Northeast Japan. The oribatid fauna of the subalpine zone showed the following percentage of Gymnonota, (2) An increase in the species number of the family Caratozentidae, (3) A decrease in the species number of the family Oppiidae, (4) A scarcity of Euphthiracaridae, Otocepheidae and Haplozetidae which appear commonly below the mongane zone, (5) A lack of Liacarus nitens and Liacarus yezoensis which are distributed in the subalpinezone of the Chubu, Kanto and Hokkaido -districts. The species composition of oribatid communities is related to the structure and form of vegetation. The tendency has also been found in the oribatid communities in the subalpine zone of Mt. Asahi-dake, Mt. Iide-san and Mt. Azuma-san investigated previously.}, pages = {61--72}, title = {東北地方北部の亜高山帯のササラダニ相 : 八甲田山, 岩手山および秋田駒ヶ岳}, volume = {19}, year = {1993} }
