干潟底生動物の分布要因の解析的研究

抄録

To analyze the mechanism of establishment and succession of the intertidal flat community, eight types of column designed to produce the artificial disturbance against some environmental conditions were buried in a brakish intertidal flat. The interaction between the change of water and/or bottom environment and the settlement of community was pursued. It was revealed that the establishment and distribution of some characteristric benthic and sessile invertebrates closely interacted with some water qualities such as dissolved oxygen, water velocity and rate of passing water through the bottom, as well as the bottom qualities such as the thickness of deposit, Eh potentials, total carbon and nitrogen contents.
