The data argue in favour of physical rather than biological control of community structure. A strong correlation exists between species distribution and two major physical parameters, namely emergence/submergence (E/S) regime and the degree of exposure to wave impact. A two-dimensional conceptual model was derived, in which the habitat of each species is delimited by specific combinations of the two parameters. Thus, <i>C. dentatus</i> occurs under virtually any E/S regime where wave impact is low. <i>O. angulosa</i> in turn occurs where E/S ratios are low, but where wave impact is intermediate to high, whereas <i>T. serrata</i> occupies an intermediate position in terms of both parameters. Although individual habitats overlap over a limited range of physical conditions, there was no evidence that competition controls the distribution or zonation of these species. The model is consistent with the distribution patterns observed along the entire Southeast African coastline, and amongst other things, also explains the occurrence of zonation patterns. Circumstantial evidence suggests that the segregative process occurs after the larvae arrive on the shore, but prior to metamorphosis. The model may have implications for other intertidal organisms, including algae.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Physical factors in barnacle community structure: a conceptual model","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":1989,"MonPub":null,"DateUpdate":"2001-10-04","DateCreate":"2001-08-30","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16941,"PubliDate":1989,"Pagination":"405-410","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":null,"BRefMon":16905,"BRefMonRR":"<b>Ros, J.D.
