| 内容記述 | 1. For the purpose of anlyzing the structure of invertebrates communities existing in the canopy and in the bark of the coniferous forest, an ecological survey was carried out from June to October of 1971 in the Otanomosunotaira Plateau (IBP area) in the Shiga Heights Area of Central Japan. 2. Compared with the survey results obtained in 1970, there was no change in the faunistic composition in the canopy of the trees of Abies mariesii, Tsuga diversifolia and Betula ennanii. 3. Regarding the seasonal changes in the faunistic composition and in the biomass in the canopy of each tree, the following facts were recongnized : (1) Compared with the individual numbers and biomass of each tree in 1970, there was generally found a decrease in their numbers in 1971. There were three reasons for this: (1) budding of the trees set in late June, (2) there was a hailstorm in August with hailstones as large as ping-pong balls (φ3.5cm) and, (3) it snowed in November. (2) The maximum number of Hemiptera 2 (Deltocephalidae sp.) was counted in August, and Araneida has increased throughout the year. The biomass of both Lepidoptera larvae and Araneida occupied more than 80% of the total in the canopy of Abies mariesii, in 1971. Araneida was dominant in the spring and Lepidoptera larvae were dominant in autumn. See figures 2 & 5. (3) Apart from an outbreak of Hemiptera 2 in September 1971, Lepidoptera larvae and Araneida were dominant in biomass throughout the year. The maximum biomass of Lepidoptera larvae was found in June 1971 in the canopy of Tsuga divcrsifolia. Individual numbers of Lepidoptera larvae decreased from spring to autumn in 1971. See Figures 3 & 6. (4) we have not recongnized the remarkable fluctuation in individual numbers and in biomass in the canopy of BetuLa ermanii, in 1971. See Figures 4 & 7. 4. Total numbers of inverteberates in the bark of the trees, Abies mariesii, Tsuga diversifolia were 1244/10㎡ and 288/10㎡, respectively. In addition to the invertebrates communities in the canopy of Abiesmariesii and, Tsuga diversifolia, some terrestrial and soil invertebrates as Opilionida, Pseudoscorpionida, Oribatei, Diplopoda, Nematoda and Oligochaeta were collected. See Tables 1, 2, 3 and Figure 1. | |||||||
