Distribution of recent Ostracoda from the coastal zone of Gaode and Weizhou Island, Zhuang Autonomous Region of Guangxi

This paper deals with the recent ostracods and their distribution in littoral zones.The ostracods studied in this paper are all from the coastal zones of Gaode and Weizhou Island, Zhuang Autonomous Region of Guangxi.The present study shows that the richness and diversity of the ostracods from Gaode area are rather lower as compared with those from Weizhou Island, where individual numbers increase constantly from supralittoral to sublittoral zones.The ostracod associations of Weizhou Island are similar to those reported from the east coast of the Weizhou Island, and most of them are littoral and benthic forms of the order Podocopida and only a few of them are members of the order Myodocopoda (e.g.Rutiderma, Cylindroleberis and Polycope).In this paper, the distributive character of the ostracods in the studied areas is analysed and discussed synthetically on the ground of their ecology, which will provide new information for the study of ecologic habitats, biogeographic provinciality and the Cenozoic biostratigraphy of ostracods.
