底栖动物

Tanakae, which indicated that L. tanakae could be classified as a benthic carnivorous predator. At the species level, Crangon affinis was the most important prey species. At one station in the north part of this area, large amounts of fish eggs of Hexagrammos otakii were found in the stomachs of L.

研究结果表明，生长季内海三棱藨草带大型底栖动物的多度和生物量整体呈上升趋势，但是月间存在一定波动变化，9月份多度最高，平均为1536ind／m^2，10月份生物量最高，平均为21.60g／m^2；不同月份优势类群组成、多度及生物量特征存在明显差异，瓣鳃类仅在部分时段表现出优势特征。

The overall appearance of these fossils reflects a shelf sedimentary environment, which fit in with the neritic sedimentary environ ment reflected by the trace element feature of the mudstone and sandstone.

遗迹化石。这些遗迹化石及浅海底栖动物化石在总体面貌上反映了陆棚沉积环境，与泥岩、砂岩的微量元素特征所指示的近岸沉积环境是一致的。

Alterniflora influenced the macrobenthos by competing with Phragmites australis and changing the hydro-geological conditions.

3发育时间较长的互花米草盐沼比发育时间短的支持了丰度和多样性更高的大型底栖动物群落。

With the passage of time, species numbers of polychaeta increased (from 3 to 6) while species numbers and abundance of macrobenthos increased. A new pattern of macrobenthos was formed.

互花米草盐沼发育初期，大型底栖动物群落以腹足类为主，丰度和多样性较低，物种丰富度(d=2.18)和多样性(H′=2.19)均低于芦苇盐沼(d=2.61，H′=2.29)。

Chongming Dongtan wetland plant is composed by mariqueter grass scirpus community,reed communities and Spartina alterniflora communities.The resource of bird is rich,there are records of up to 136 kinds of water birds.

崇明东滩湿地的植被群落主要由海三棱藨草群落、芦苇群落和互花米草群落等组成；鸟类资源丰富，有记录的水鸟达136种；底栖生物大型底栖动物45种，隶属于5门7纲。

The results gained support from the analysis of unweighted pair-group method with arithmetic.

这一现象同时体现在小型底栖动物主要类群的分布及相似生境聚类分析的结果上。

The results show that the number of zoobenthos species declines in rice-duck farming ecosystems compared with conventional paddy.

结果表明：与常规稻田相比，稻鸭共作使水体底栖动物的种类数减少。

Zoobenthos is an important components of lake ecosystem and play multiple functions in aquatic ecosystem.

中文摘要：底栖动物是湖泊生态系统的重要组成部分，发挥着多种生态功能。

Zoobenthos are one of the major ecological groups in fresh waters. They play an important role in nutrient cycling and energy flow in ecosystems, and are very useful food resources for fish.

底栖动物是淡水生态系统的一个主要组成部分，在渔业和环境科学上均有重要的理论意义和广泛的应用前景。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
