抽象的。利用两张围网对河口鱼类群落的时间变化进行了研究。鱼类区系的主要时间变化是每月的功能，特别是春季/小潮的差异，而不是短期的潮/落变化。这一趋势是相对一致的两种尺寸的网眼网，这表明发生的春季/小潮渔获量组成的变化是一个系统的特点和独立的池可用的物种。营养模式一般更强，更一致的分类趋势，结果突出了详细的喂养相互作用的了解过程中的重要性，影响多物种群落的时间变化。
Abstract. Temporal changes in an estuarine fish assemblage were investigated using two seine mesh nets. Major temporal changes in the fish fauna were a function of both monthly and, in particular, spring/neap differences, rather than short-term ebb/flood changes. This trend was relatively consistent for two sizes of mesh nets, suggesting that the occurrence of spring/neap changes in catch composition were a characteristic of the system and independent of the pool of available species. Trophic patterns were generally stronger and more consistent than taxonomic trends, a result highlighting the importance of detailed knowledge of feeding interactions in understanding the processes influencing temporal changes in multi-species communities.
