The deep-sea amphipod <i>Eurythenes gryllus</i> Lichtenstein (Crustacea: Lysianassoidea) is considered a panoceanic, cold-water stenotherm, with a vertical depth distribution from 184 to 6500 m. We surveyed mtDNA sequence diversity in <i>E. gryllus</i> to assess genetic diversity and population structure in different oceans and across traditionally defined bathyal and abyssal zones. DNA sequences (437 nucleotides length) from the mitochondrial large-subunit ribosomal RNA gene (16S rRNA) of 95 individuals, collected between 1982 and 1990 from 14 locations in the central North Pacific (including multiple samples on the slope of a seamount), castern and western North Atlantic, and the Arctic Ocean, were obtained. Our analysis of DNA sequence diversity indicates (1) genetic homogeneity among sites within the same depth zone at the scale of ocean basins; and (2) genetically divergent, cryptic taxa distributed at different depths, with the greatest diversity in the bathyal zone. These observations suggest that ecological and physical conditions are important isolating mechanisms that may lead to speciation in this group.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Geographic and bathymetric patterns of mitochondrial 16S rRNA sequence divergence among deep-sea amphipods, <i>Eurythenes gryllus</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:32:43.197731","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1996,"MonPub":null,"DateUpdate":"2022-05-25","DateCreate":"2022-05-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1996VR10300008","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/bf00351330"},"refs":null,"anarec":{"AnaID":352177,"PubliDate":1996,"Pagination":"633-643","XtraPublOfAnaID":null,"ISBN":null,"Volume":"126","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
