In the exposed habitat, patches of white sulphur bacteria had a limited lifetime and displayed a characteristic succession in which small sulphur bacteria (<i>Thiospira, Macromonas</i>) dominated at first followed by <i>Thiovulum</i>, which was eventually displaced by <i>Beggiatoa</i>; during summer phototrophic organisms dominated. <i>Thiovulum</i> films were only ~0.2 mm thick and the projected area of the cells covered only 7 to 36% of the sediment surface while mats of filamentous bacteria were thicker and represented a higher biomass. In the protected locality the Beggiatoa mats were ~0.6 mm thick and represented a 10-fold higher biovolume than those from the exposed habitat. The projected area of the filaments covered 2 to 3x the surface area of the sediment and had a combined length of 10 to 70 m cm-2. The mats had a porosity of 90 to 95% and did not contain a mucous matrix. Phototrophs (mainly filamentous cyanobacteria and diatoms) were always present. Protozoan biota included more than 80 species and represented a high cell density (corresponding to 104-105 ciliates ml-1 in addition to flagellates and lobose amoebae). Many species depended on sulphur bacteria for food. The mats sometimes also harboured several representatives of meio- and macrofauna.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Mats of colourless sulphur bacteria. 2. structure, composition of biota and successional patterns","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":1995,"MonPub":null,"DateUpdate":"2009-04-10","DateCreate":"2009-04-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1995TN17100017","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":133635,"PubliDate":1995,"Pagination":"171-179","XtraPublOfAnaID":null,"ISBN":null,"Volume":"128","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
