Six studies in this special issue dealt with modern nannoplankton assemblages. In total during these studies 552 samples were analysed and about 180,000 specimens identified, from 152 species. This paper provides a unified list of taxa from these studies, records the presence/absence of each species across the studies and indicates the more common species. Comparison of results indicates a high level of consensus on taxonomy and a high commonality of the floras. (C) 2000 Elsevier Science B.V.
