Here we document for the first time the extensive presence of sticky hairs covering <i>P. oceanica</i> seedling roots. Adhesive root hairs allow the seedlings to firmly anchor to rocky substrates with anchorage strength values up to 5.23 N, regardless of the presence of algal cover and to colonise bare rock without the need for precursor assemblages to facilitate settlement. Adhesive root hairs are a morphological trait common on plants living on rocks in high-energy habitats, such as the riverweed Podostemaceae and the seagrass <i>Phyllospadix scouleri</i>. The presence of adhesive root hairs in <i>P. oceanica</i> juveniles suggests a preference of this species for hard substrates. Such an adaptation leads to hypothesize a new microsite driven bottleneck in <i>P. oceanica</i> seedling survival linked to substrate features. The mechanism described can favour plant establishment on rocky substrates, in contrast with traditional paradigms. This feature may have strongly influenced <i>P. oceanica</i> pattern of colonisation through sexual propagules in both the past and present.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Evidences of adaptive traits to rocky substrates undermine paradigm of habitat preference of the Mediterranean seagrass <i>Posidonia oceanica</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:32:41.768267","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2015-03-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000350454100006","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/srep08804"},"refs":null,"anarec":{"AnaID":245425,"PubliDate":2015,"Pagination":"6 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5","Issue":"8804","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
