Identification of operational taxonomic units (OTUs) is one of the crucial steps in the process and can be accomplished using several different approaches, namely, alignment-based, probabilistic, tree-based and phylogeny-based. The number of identified sequences in the reference databases affects the precision of identification. This paper compares the identification of marine nematode OTUs using alignment-based, tree-based and phylogeny-based approaches. Because the nematode reference dataset is limited in its taxonomic scope, OTUs can only be assigned to higher taxonomic categories, families. The phylogeny-based approach using the evolutionary placement algorithm provided the largest number of positively assigned OTUs and was least affected by erroneous sequences and limitations of reference data, compared to alignment-based and tree-based approaches.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Taxonomy assignment approach determines the efficiency of identification of OTUs in marine nematodes","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":"biodiversity; identification; barcode; nematodes; metabarcoding;meiobenthos","OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-08-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000408764400026","VABBcode":null,"OpenAcc":1,"DOI":"10.1098/rsos.170315"},"refs":null,"anarec":{"AnaID":288369,"PubliDate":2017,"Pagination":"170315","XtraPublOfAnaID":null,"ISBN":null,"Volume":"4","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":247720,"SerRR":"Royal Society Open Science.
