The <i>Posidonia oceanica</i> seagrass distribution was mapped with the help of aerial photographs, side scan sonar and GIS. In addition, the temporal variations of its distribution were studied by aerial photographs and GIS from 1955 to 2000. Finally, coverage and shoot density were measured via scuba-diving. This work reveals (i) the regression of the <i>P. oceanica</i> meadow at sites where harbours have been built, (ii) the occurrence of spaces within the meadow free of live <i>P. oceanica</i> (“intermattes”), which account for 8% of its surface area, (iii) a deep area where <i>P. oceanica</i> coverage and shoot density are low and (iv) evidence of regression, although modest, of the meadow at its lower limit. Nevertheless, the study site also exhibits an extensive and on the whole relatively healthy meadow whose limits have changed little over time.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Spatial, temporal and structural variations of a <i>Posidonia oceanica</i> seagrass meadow facing human activities","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-25 01:31:08.648096","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Posidonia oceanica; aerial photography; side scan sonar; GIS; humanimpact","OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2020-10-19","DateCreate":"2006-04-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000236617300002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2005.10.001"},"refs":null,"anarec":{"AnaID":98305,"PubliDate":2006,"Pagination":"287-293","XtraPublOfAnaID":null,"ISBN":null,"Volume":"84","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
