Fukuyama, K. and M. Ito, 1992. Succession of oribatid mites(Acari: Cryptostigmata)Community in soil and in needle litter after reforestation of Cryptomeria japonica in Japan. J. Acarol. Soc. Jpn., 1(2): 113-126.
A comparison of oribatid mite communities inhabiting soil and needle litter in differently aged(6, 13, 38 and 80 year old)plantations of Cryptomeria japonica D. Don was carried out at Mt. Tsukuba, in central Japan. The density of the microarthropods was highest in the youngest stand and lowest in the 38-year-old. The distribution pattern of dominant species of oribatid mite among study sites was divided into 4 types. Type 1 was related to the mass of the soil organic material. Type 2 was related to soil humidity. Type 3 was related to the mass of needle litter. And type4 was related to the age after reforestation. Exchange between closely related species occurred among differently aged forests. Four oribatid species were recovered from the needle litter of C. japonica. Rhysotritia ardua(Koch)and Hoplophthiracarus foveolatus Aoki are dominant species inhabiting in the needle litter.
