Populations of the alga were found to remain at their 1985 level in Lake Grevelingen, with a small eastward expansion into the Eastern Scheldt estuary. A new population for the brackish, non-tidal Lake Veere is reported. Within Lake Grevelingen <i>S. muticum</i> forms a persistent, extensive canopy of 100% cover (4,442.5 ± 525.6 g fresh wt m<sup>-2</sup>, 640.3 ± 75.8 g dry wt m<sup>-2</sup>) that has a marked effect upon the penetration of photosynthetically active radiation (PAR) (reduced by 97% at 0.1 m). Surface sea water temperatures can be elevated by 2.7 °C above water not associated with a <i>Sargassum</i> canopy; furthermore, the dense canopy shades and hence reduces water temperatures below 0.1 m depth. Productivity studies indicate that assimilation occurs in the upper levels of the canopy (57.09 µg C mg dry wt<sup>-1</sup> m<sup>-2</sup> at a mean PAR rate of 106.7 J cm<sup>-2</sup> h<sup>-1</sup>). Self-shading and a resultant decrease in the rate of assimilation was evident below the canopy.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Canopy characteristics of the brown alga <i>Sargassum muticum</i> (Fucales, Phaeophyta) in Lake Grevelingen, Southwest Netherlands","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":"2009-05-18","DateCreate":"2009-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1990EF41000030","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/BF00040236"},"refs":null,"anarec":{"AnaID":135680,"PubliDate":1990,"Pagination":"211-217","XtraPublOfAnaID":null,"ISBN":null,"Volume":"204-205","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42943,"SerRR":"Hydrobiologia.
