These small-sized (< 1µm) species are rich in the red pigment phycoerythrin (PE) and belong to the <i>Synechococcus</i>-type species that was studied in continuous culture. The cell concentrations were assessed by using the characteristic PE-absorbance peak at 545 nm in the <i>in vivo</i> absorption spectra as tracer and epifluorescence microscopy. Picocyanobacteria were found in relatively high concentrations (10<sup>4</sup>-10<sup>5</sup> cells·cm<sup>-3</sup>) at 75% and 96% of the Banda Sea stations of cruise 1 and 2, respectively. The cell-numbers were higher during the first cruise, but their relative importance (as part of the total phytoplankton-biomass) was higher during the second cruise. The species showed a preference for deeper layers where light intensities were low. Their low surface abundance seemed to show a diurnal pattern (<i>i.e.</i> decreasing during the course of the day), correlated with surface irradiance. The occurrence of such a diurnal pattern is discussed in relation with results of light shift experiments with continuous cultures of <i>Synechococcus</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Picocyanobacteria in the Banda Sea during two diferent monsoons","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2001-09-24","DateCreate":"2001-08-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16441,"PubliDate":1990,"Pagination":"513-521","XtraPublOfAnaID":null,"ISBN":null,"Volume":"25","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
