Previous genetic and morphological studies of the two species found in the Atlantic today suggested two possible scenarios for the speciation of <i>A. rubens</i> and <i>A. forbesi</i>. Through phylogenetic and population genetic analysis of data from a portion of the cytochrome oxidase I mitochondrial gene and a fragment of the ribosomal internal transcribed spacer region, I show that the formation of the Labrador Current 3.0 Ma was probably responsible for the initial vicariance of North Atlantic <i>Asterias</i> populations. Subsequent adaptive evolution in A. forbesi was then possible in isolation from the European species <i>A. rubens</i>. The contact zone between these two species formed recently, possibly due to a Holocene founding event of <i>A. rubens</i> in New England and the Canadian Maritimes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biogeography of <i>Asterias</i>: North Atlantic climate change and speciation","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:31:25.065030","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2003-04-07","DateCreate":"2003-04-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000170748600012","VABBcode":null,"OpenAcc":0,"DOI":"10.2307/1543530"},"refs":null,"anarec":{"AnaID":33931,"PubliDate":2001,"Pagination":"95-103","XtraPublOfAnaID":null,"ISBN":null,"Volume":"201","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42437,"SerRR":"The Biological Bulletin.
