Here, we investigated the species limits of morphologically similar small–celled strains of the model diatom <i>Sellaphora</i> from the United Kingdom and Australia, using <i>cox</i>1 mitochondrial and <i>rbc</i>L chloroplast gene sequences. Based on <i>cox</i>1 sequence data, the sequenced strains belonged to six closely related lineages, presumably species, of which one corresponds to the previously described <i>S. auldreekie</i> D.G. Mann & S.M. McDonald. Although <i>rbc</i>L displayed less sequence variation, the same six lineages were also recovered in an <i>rbc</i>L phylogeny of the genus. Molecular species discovery was compared to mating trials involving three of the lineages, showing that they were reproductively isolated. Incomplete evidence from a fourth lineage suggested that it too was reproductively isolated. <i>A posteriori</i> examination of light microscope morphology revealed no simple metrics or presence/absence characters that could consistently separate all species of the <i>auldreekie</i> complex, even though some do differ in pole width or stria density. While it is premature to make conclusions about their biogeography, it is obvious that a number of cryptic <i>Sellaphora</i> species thus far undetected in the UK are easily found at several localities in warm–temperate Australia.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Molecular species discovery in the diatom <i>Sellaphora</i> and its congruence with mating trials","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"coxl; cryptic species; diatoms; rbcL; reproductive isolation;Sellaphora; species delimitation","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2017-11-09","DateCreate":"2014-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000325599900004","VABBcode":null,"OpenAcc":1,"DOI":"10.5507/fot.2013.012"},"refs":null,"anarec":{"AnaID":238155,"PubliDate":2013,"Pagination":"133-148","XtraPublOfAnaID":null,"ISBN":null,"Volume":"13","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":229174,"SerRR":"Fottea.
