The flowering frequency of <i>P. oceanica</i> varied among years, ranging between 7.9 and 19.8%. Despite the large number of flowers and ovules, few of these produced mature fruits owing to abortion. Moreover, about 84% of developing inflorescences were damaged by herbivores. Fruit production varied among years, ranging from 4.7 to 13.5 fruits per m2, but reproductive success remained constant (2.0-2.4%). Exclusion of herbivores showed that abortion alone was reponsible for the loss of about 87% of the reproductive potential. Since reduced fertilization did not completely explain the observed frequency of abortion, it was hypothesized that post-fertilization factors could affect seed formation. The higher reproductive success of protected plants (11.2%) compared to herbivore-exposed plants (3.1%) indicated that predation significantly reduced the number of seeds available for establishment. We concluded that pre-dispersal seed losses to abortion and predation may seriously reduce the reproductive success of the species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Sexual reproductive success in <i>Posidonia oceanica</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"seagrasses; Posidonia oceanica; fruit abortion; fruit predation;reproductive success","OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2003-01-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000180605800003","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/s0304-3770(02)00151-1"},"refs":null,"anarec":{"AnaID":31134,"PubliDate":2003,"Pagination":"21-32","XtraPublOfAnaID":null,"ISBN":null,"Volume":"75","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
