Its present range and population density were determined by surveying 24 sites on the west and south coasts of South Africa. <i>B. glandula</i> occurred over approximately 400 km of coastline, from Elands Bay in the north-west to Misty Cliffs on the west coast of the Cape Peninsula. The abundance of <i>B. glandula</i> was affected by site, zone, prevalence of upwelling, and orientation of the shore. Its distribution was very patchy, both on macro- and microscales, with Bloubergstrand and Moullie Point having the highest abundances of 28 445 and 24 500 individuals m-2 respectively. <i>B. glandula</i> was the dominant barnacle at all West Coast sites where it was recorded, comprising 78.5% of all barnacles found. The successful invasions of <i>B. glandula</i> in South Africa, Argentina and Japan suggest that this species poses a potential threat to intertidal communities in cool, temperate waters.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Present distribution and abundance of the introduced barnacle <i>Balanus glandula</i> Darwin in South Africa","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-19 01:32:27.189055","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2019-08-26","DateCreate":"2008-11-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000258551900010","VABBcode":null,"OpenAcc":0,"DOI":"10.2989/AJMS.2008.30.1.9.459 "},"refs":null,"anarec":{"AnaID":127527,"PubliDate":2008,"Pagination":"93-100","XtraPublOfAnaID":null,"ISBN":null,"Volume":"30","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":78939,"SerRR":"African Journal of Marine Science.
