The objective was to describe these southern coastal systems and measure the extent to which they vary in terms of fundamental measures of community structure. The Magellan Region constitutes an intermediate site between relatively well-studied temperate regions and Antarctica. Previous studies suggest that dominant canopy species may reflect different disturbance histories and associated communities may similarly be expected to vary structurally. We hypothesized that variation in subtidal sessile assemblages in the Magellan Strait, where <i>Macrocystis pyrifera</i> widely dominates, would be less than at Antarctic sites, where <i>Desmarestia</i> spp. or <i>Himantothallus grandifolius</i> may dominate depending on disturbance regimes. Our results showed that benthic assemblages in the Magellan Strait were similar where physical structure of the reef was similar, but differed strongly where reef form differed. At sites in South Shetland Islands, benthic assemblages differed in terms of dominant macroalgae and sessile community structure; however evidence that the <i>Desmarestia</i>-dominated site was more highly disturbed was equivocal. Shading produced by <i>Macrocystis</i> in Magellan Strait and ice effect in Antarctica are likely strong structuring factors in their respective communities, which would need to be considered when comparing community characteristics.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Rocky reef benthic assemblages in the Magellan Strait and the South Shetland Islands (Antarctica)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-01 01:31:48.174248","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Macroalgae, canopy, hard substrates, Magellan Region, Southern Ocean","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-08-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000294420600007","VABBcode":null,"OpenAcc":1,"DOI":"10.4067/S0718-19572011000200007"},"refs":null,"anarec":{"AnaID":288561,"PubliDate":2011,"Pagination":"177-188","XtraPublOfAnaID":null,"ISBN":null,"Volume":"46","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43879,"SerRR":"Revista de Biología Marina y Oceanografía.
