Clearly distinct allele and genotype frequencies were observed between the north (20–41°N) and mid-south (10°N–33°S) Atlantic samples. Much lower frequency of A allele (37.5–57.1%) was observed in the north samples (n = 160 in total) than in the mid-south samples (83.3–92.6%; n=354), and homozygote BB was common in the north samples (23.4–31.3%) but very rare or absent (0–3.9%) in the mid-south samples. Very strong population subdivision was observed between the two groups (F ST = 0.34, P < 0.001), while the allele and genotype frequencies within each ocean basin persisted over time (1990–2002 in the north, and 1994–2002 in the mid-south). Of two samples from the presumed boundary zone, one (n = 18) (14°N, 48°W) presented intermediate frequencies of the A allele (66.7%) and BB homozygote (11.1%), while the other (n = 23) (10–17°N, 28–37°W) shared similar frequencies of the A allele (89.1%) and BB homozygote (4.3%) with those of the mid-south Atlantic samples. These results indicate that the gene flow and individual migration between the north and mid-south Atlantic populations are considerably restricted and that the current management boundary between the north and south Atlantic swordfish stocks of 5°N should be reconsidered.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Boundary between the north and south Atlantic populations of the swordfish (Xiphias gladius) inferred by a single nucleotide polymorphism at calmodulin gene intron","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:32:54.597542","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2007,"MonPub":null,"DateUpdate":"2016-07-06","DateCreate":"2016-07-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000247471700009","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-007-0662-8"},"refs":null,"anarec":{"AnaID":259685,"PubliDate":2007,"Pagination":"87-93","XtraPublOfAnaID":null,"ISBN":null,"Volume":"152","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
