In order to assess the phylogeography and genetic population structure of <i>A. triostegus</i> across its range, 35 individuals were sampled from five localities in the western Indian Ocean and complemented with 227 sequences from two previous studies. Results from the overall analysis of molecular variance (AMOVA) without a priori grouping showed evidence of significant differentiation in the Indo‐Pacific, with 25 (8.3%) out of 300 pairwise <i>Φ</i><sub>ST</sub> comparisons being significant. However, the hierarchical AMOVA grouping of Indian and Pacific Ocean populations failed to support the vicariance hypothesis, showing a lack of a genetic break between the two ocean basins. Instead, the correlation between pairwise <i>Φ</i><sub>ST</sub> values and geographic distance showed that dispersal of <i>A. triostegus</i> in the Indo‐Pacific Ocean follows an isolation‐by‐distance model. Three haplogroups could be deduced from the haplotype network and phylogenetic tree, with haplogroup 1 and 2 dominating the Indian and the Pacific Ocean, respectively, while haplogroup 3 exclusively occurring in the Hawaiian Archipelago of the central Pacific Ocean.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Genetic population structure of the convict surgeonfish <i>Acanthurus triostegus</i>: a phylogeographic reassessment across its range","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:32:44.034332","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"genetic diversity; Indo-Pacific barrier Kenya; Madagascar; mtDNA;Tanzania","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2019-03-13","DateCreate":"2018-11-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000448079400004","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/jfb.13686"},"refs":null,"anarec":{"AnaID":302984,"PubliDate":2018,"Pagination":"597-608","XtraPublOfAnaID":null,"ISBN":null,"Volume":"93","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43231,"SerRR":"Journal of Fish Biology.
