| Research Abstract |
A method of extracting DNA from oribatid mites that preserved the voucher specimen was established. Moreover, phylogenetic tree including arboreal and soil-living species suggests that arboreal life have evolved many times independently, and parthenogenesis have evolved many times in the soil environment. In addition, this study finds that parthenogenetic species tend to become dominant in early stage of leaf decomposition, and parthenogenetic species is able to live in suspended soils existing at arboreal habitats.
