There is such less modifiability for those coordination patterns which constitute species-specific behavior than is usually realized, and we must keep in mind that most behavioral traits have species-specific aspects.

Based on the data of four seasonal investigations in Yangtze River estuary (28°00'-32°00'N, 122°00'-123°30'E) from the year 2002 to 2003, the distribution pattern of pelagic mollusc, the seasonal changes of total abundance and the species composition were analyzed. Furthermore, environmental adaptation of dominant species was deduced through scatter plot of abundance and temperature-salinity.

根据2002-2003年长江口28°00'-2°00'N、122°00'-123°30'E海域4个季节的海洋调查资料，运用定量、定性方法，探讨了长江口邻近海域浮游软体动物总丰度的平面分布、季节变化、种类组成及优势种的环境适应类型。

The reduction of species richness was the most remarkedble in Trichoptera and Mollusca. Species succession of macrozoobenthos was closely related to the changes in environmental conditions such as the isolation of the lake from the river, eutrophication, and disappearance of macrophytes. Perhaps, the latter two changes were more important.

分析表明东湖底栖动物群落的演替与湖泊环境条件的变化关系密切，这些变化主要包括：江河阻隔，湖泊富营养化的加剧以及水生高等植物的消失，其中后两个因素相对前一个显得更为重要。
