The spatial structure and the dynamics of microphytobenthic biomass during tidal emersion were investigated by creating high resolution fluorescence distribution maps of biomass (Fo) at the sediment surface (0.5 cm pixels, 20 cm×20 cm). The PSII maximum quantum efficiency was also calculated for correlation with biomass structure. Intertidal areas of the Biezelingsche Ham (Westerschelde) and Zandkreek (Oosterschelde), The Netherlands, were sampled during June 2000. The space–time variability of the discrete fields obtained was analysed by studying their spatial variogram and their time autocorrelation. Sites showed significant differences in absolute variation of microphytobenthic biomass and in the dynamics of the development of spatial structure throughout the emersion period. The variograms indicated little spatial correlations in the biomass fields above the 2 cm scale, while the time autocorrelation showed a strong persistence of biomass structure at time scales between 1 h and 5 h. The Biezelingse Ham biofilm was shown to be migratory in nature while the Zandkreek system was more stable. At the former site, biomass distribution became more homogenous with time, as upward migration of cells attenuated horizontal patchiness. At the Biezelingsche Ham site, maximum PSII quantum efficiencies varied inversely with biomass areas; reasons for this may include nutrient depletion and CO2 limitation within dense biofilms.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Spatial dynamics of microphytobenthos determined by PAM fluorescence","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":"microphytobenthos; PAM fluorescence; patchiness; spatial distribution","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2015-10-12","DateCreate":"2011-10-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000232643700003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.ecss.2005.05.005"},"refs":null,"anarec":{"AnaID":208285,"PubliDate":2005,"Pagination":"30-42","XtraPublOfAnaID":null,"ISBN":null,"Volume":"65","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44109,"SerRR":"Estuarine, Coastal and Shelf Science.
