A critical assessment of published distribution records and additional identifications based on <i>cox</i>1, <i>psb</i>A and <i>rbc</i>L genetic markers confirm the presence of <i>D. acutiloba</i> at a number of locations in the Indo-Pacific as well as three locations along the Israeli coastline in the south-eastern Mediterranean Sea. The close genetic affinity between introduced specimens and those from a population in Hurghada (Red Sea) strongly suggests an introduction via the Suez Canal. The occurrence of <i>D. acutiloba</i> in these regions is further supported by predictions made by correlative ecological niche models (ENMs), which show high suitability values in the northern Red Sea and the Levantine Basin. In contrast, environmental conditions in the western Mediterranean and parts of the north-eastern Mediterranean are currently less favourable, as evidenced by the lower predicted probability of occurrence. Under future scenarios, the suitability of these regions increases. The further spread of <i>D. acutiloba</i> in the eastern Mediterranean seems imminent, and the species may even extend its range to the western Mediterranean Sea, depending on the climate change scenario considered. While <i>D. acutiloba</i> can be relatively easily distinguished from the majority of Mediterranean <i>Dictyota</i> species, it remains difficult to differentiate this species from narrow growth forms of <i>D. dichotoma</i>. Therefore, we recommend the use of molecular markers such as <i>cox</i>1, <i>psb</i>A and <i>rbc</i>L, to unequivocally identify this species and monitor its further spread.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Tracing the introduction of <i>Dictyota acutiloba</i> (Dictyotales, Phaeophyceae) in the Mediterranean Sea, with a reassessment of its geographic distribution","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:32:34.967043","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"ecological niche models; introduced seaweed; Lessepsian migration; Mediterranean Sea","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2025-09-18","DateCreate":"2023-11-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001012013900001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/09670262.2023.2214184"},"refs":null,"anarec":{"AnaID":369116,"PubliDate":2024,"Pagination":"38-50","XtraPublOfAnaID":null,"ISBN":null,"Volume":"59","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42675,"SerRR":"European Journal of Phycology.
