Hydrocorals of the genus <i>Stylaster</i>, commonly known as lace corals, form small branching colonies that enhance three-dimensional complexity on reefs and are known to support a variety of commensal species. Furthermore, the genus is highly speciose, further increasing biodiversity. Despite their important ecological roles, little is known about the evolutionary history and the intraspecific diversity and structure in these broadly distributed hydrocorals. Here, we assessed the phylogenetic relationships among Atlantic species in the genus <i>Stylaster</i> and examined the genetic structure of <i>S. roseus</i> in the Tropical Western Atlantic (Caribbean and Brazil) and of <i>S. blatteus</i> in the Tropical Eastern Atlantic (Africa), using DNA sequences from the 16S ribosomal gene. Time-calibrated phylogenetic analyses showed that <i>S. roseus</i> and <i>S. blatteus</i> diverged at ~ 24.6 Ma. A well-supported Brazilian clade within <i>S. roseus</i> indicates a possible cryptic species that diverged at ~ 11.6 Ma, consistent with the formation of the Amazon River at 9 Ma (Hoorn et al. in Glob Planet Change 153:51–65, 2017). Strong genetic structure was observed even over moderate distances, with Φ<sub>ST</sub> values over all populations being 0.98 for <i>S. roseus</i> and 0.90 for <i>S. blatteus</i>. Nearly, all haplotypes were private (found in a single location) and diverged by many mutational steps from one another. In contrast, genetic diversity was low at the local scale for both species, with most sites showing no variation (a single haplotype). These results are coherent with the reproductive strategy of Stylasteridae, where larvae are brooded and are highly developed at the time of release, often settling near the parental colony. Limited dispersal coupled with possible clonal reproduction have likely contributed to the high levels of genetic differentiation observed here. Lace corals show unusual reproductive and population dynamics compared to other reef inhabiting cnidarians. Future work may reveal additional cryptic diversity in this poorly studied family.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Remarkable population structure in the tropical Atlantic lace corals <i>Stylaster roseus</i> (Pallas, 1766) and <i>Stylaster blatteus</i> (Boschma, 1961)","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":"Stylaster; Brazilian province; Caribbean province; population structure; population genetics","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-05-23","DateCreate":"2023-04-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000886841100001","VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s00338-022-02329-5"},"refs":null,"anarec":{"AnaID":363327,"PubliDate":2023,"Pagination":"181-194","XtraPublOfAnaID":null,"ISBN":null,"Volume":"42","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45580,"SerRR":"Coral Reefs.
