We used morphological and molecular (LSU, and two fragments of SSU sequences) approaches to evaluate 236 nematodes. Specimens were assigned to at least genera using morphology and were assessed for the presence of cryptic speciation. The following genera were identified: <em>Halomonhystera</em>, <em>Litoditis</em>, <em>Enoploides</em>, <em>Chromadorita</em>, <em>Theristus</em>, <em>Oncholaimus</em>, <em>Viscosia</em>, <em>Gammanema</em>, <em>Bathylaimus</em>, <em>Choanolaimus</em>, and <em>Paracanthonchus</em>; along with specimens from the families Anticomidae and Linhomoeidae. Cryptic speciation was identified within the genera <em>Halomonhystera</em> and <em>Litoditis</em>. All of the cryptic species identified live sympatrically. The two cryptic species of <em>Halomonhystera</em> exhibited no significant morphological differences. However, <em>Litoditis</em> species 2 was significantly larger than <em>Litoditis</em> species 1. The utility of molecular data in confirming the identifications of some of the morphologically more challenging families of nematodes was demonstrated. In terms of which molecular sequences to use for the identification of free-living nematodes, the SSU sequences were more variable than the LSU sequences, and thus provided more resolution in the identification of cryptic speciation. Finally, despite the considerable amount of time and effort required to put together genetic and morphological data, the resulting advance in our understanding of diversity and ecology of free-living marine nematodes, makes that effort worthwhile.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The identification of sympatric cryptic free-living nematode species in the Antarctic intertidal","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2019-07-18","DateCreate":"2019-07-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000412360300128","VABBcode":null,"OpenAcc":1,"DOI":"10.1371/journal.pone.0186140"},"refs":null,"anarec":{"AnaID":312890,"PubliDate":2017,"Pagination":"e0186140","XtraPublOfAnaID":null,"ISBN":null,"Volume":"12","Issue":"10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":123954,"SerRR":"PLoS One.
