综合2000、2004年的调查结果,徐闻珊瑚礁自然保护区内有造礁石珊瑚12科42种,而保护区的核心区、缓冲区和试验区内珊瑚礁低潮带至潮下带上部的8个断面10个站的大型底栖生物有8类45科101种,其中大多数种类属于印度—太平洋热带区系。优势... 综合2000、2004年的调查结果,徐闻珊瑚礁自然保护区内有造礁石珊瑚12科42种,而保护区的核心区、缓冲区和试验区内珊瑚礁低潮带至潮下带上部的8个断面10个站的大型底栖生物有8类45科101种,其中大多数种类属于印度—太平洋热带区系。优势类群是软体动物和节肢动物,底栖生物的平均生物量、栖息密度和多样性指数分别是1043.37 g/m2、692.37个/m2和5.5228。位于保护区南部核心区的断面Ⅰ和Ⅱ有着最高的多样性(5.1389和5.0077)和均匀度(0.9470和0.9286),而其他分属核心区、缓冲区和试验区的6个断面的多样性指数和均匀度指数差异不大。总体上看,造礁石珊瑚和珊瑚礁的存在为其他底栖生物提供了良好的生态环境,从而丰富了本区底栖生物的种类组成和数量。 展开更多

Knowledge of the biodiversity of Brazilian reef ecosystems has expanded in recent years with several new species. Brazil is considered an important province because it has the only true reefs in the South Atlantic. This study identified the endemism of benthic invertebrate species of the Brazilian reefs. The reef coast is approximately 600 km long and extends from the state of Rio Grande do Norte to south coast of the Bahia state, with many coral and sandstone reefs near the shoreline and in the offshore zone, where the platform top remains exposed during low tides; and also on the Abrolhos region has isolated columns and offshore banks. Four offshore sites within the EEZ (Exclusive Economic Zone) were also included in this review. This study was based on the invertebrate benthic diversity existing on the northeastern coast, represented by Porifera with 450 spp, Cnidaria Scleractinia 16 spp and Echinodermata 51 spp. Of these, 102 species are endemic to Brazilian reefs, including Porifera with 86 spp (18,44%), Cnidaria Scleractinia 8 spp (50%), and Echinodermata 8 spp (2.93%). The results reflect the recent increase in taxonomic studies, and identify a large number of endemic species among the benthic invertebrate fauna of the Brazilian reefs. 展开更多
