A long-term phytoplankton survey (REPHY-IFREMER) provided phytoplankton densities at different taxonomic levels of identification from 1995 to 1999. The database was homogenised at the taxonomic level of the genus and the log<sub>10<\/sub>-density was used as an indicator of the biomass. At all stations investigated, a strong seasonality governed the changes in the number of genera and the log<sub>10<\/sub>-density. No significant differences were found between the stations. Factorial Correspondence Analyses were performed to provide a typology of sampling dates and corresponding functional groups of genera. Pennate diatoms were dominant in winter periods, while centric diatoms and dinoflagellates characterised summer and fall periods. Moreover, the log<sub>10<\/sub>-density of pennate diatoms did not follow a seasonal pattern. The relative contribution of this group, which appeared to be the most representative of the benthic microalgal communities, had a maximum variation range of 1 to 84% and was well correlated with the turbidity recorded at the same time. This study was a first step to provide a frame for further studies about the coupling between benthic and pelagic microalgal biomasses in semi-enclosed European-type littoral ecosystems.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Benthic contribution to pelagic microalgal communities in two semi-enclosed, European-type littoral ecosystems (Marennes-Ol\u00e9ron Bay and Aiguillon Bay, France)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-14 01:31:32.826796","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"phytoplankton; microphytobenthos; community composition; factorialanalysis; time series","OtherDescriptors":"Phytoplankton; Microphytobenthos; Community composition; Factorial analysis; Time series","Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2020-10-05","DateCreate":"2004-11-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000225336400001","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":68289,"PubliDate":2004,"Pagination":"241-258","XtraPublOfAnaID":null,"ISBN":null,"Volume":"52","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
