The two forms were distinguishable by complete allele substitutions at five loci, resulting in high genetic differentiation (Nei's D: 0.533 to 0.662). No genetic evidence of hybridization between the two forms was detected in sympatric populations in three rivers. These results indicate that the two forms are reproductively isolated, clearly showing that the two forms are distinct species. The genetic differentiation among populations was higher in the large-egg form (D: 0.005 to 0.111, GST: 0.435) than that in the small-egg form (D: 0.000 to 0.001, GST: 0.020). This genetic difference between the two forms seems to be attributable to a difference in their life histories. The average expected heterozygosity was low in populations of both the large-egg form (0.005 to 0.068) and the small-egg form (0.014 to 0.038) in comparison with other marine invertebrates.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Genetic differentiation in two sibling species of the brackish-water polychaete <i>Hediste japonica</i> complex (Nereididae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-15 01:32:02.441657","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1997,"MonPub":null,"DateUpdate":"2014-08-12","DateCreate":"2007-02-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000071438600004","VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s002270050235"},"refs":null,"anarec":{"AnaID":107735,"PubliDate":1997,"Pagination":"163-170","XtraPublOfAnaID":null,"ISBN":null,"Volume":"130","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
