Bionomy of macrobenthic amphipods, molluscs and polychaetes in the Evros Delta, September 1981

The composition and distribution of the macrobenthic amphipod, mollusc and polychaete fauna in the Evros Delta have been investigated. The distribution of species showed a zonation mainly related to the degree of \"confinement\".本研究针对埃夫罗斯三角洲（Evros Delta）内的大型底栖端足类（macrobenthic amphipod）、软体动物（mollusc）及多毛类动物区系的组成与分布特征开展了调查。研究结果表明，物种分布呈现明显的分带格局，且该分带现象主要与生境封闭程度（confinement）密切相关。
