The allele frequencies from ten enzyme loci were analysed using horizontal starch gel electrophoresis. The allele frequency distributions between samples differed significantly at only three out of eleven loci. Nei's genetic distances between populations were very low. The sample from the Conwy estuary showed a consistant deficiency of heterozygosity and large deviation from Hardy-Weinberg equilibrum. The population is considered to be rather isolated and to exhibit considerable inbreeding, mainly through self-fertilization. Investigation of the salinity tolerance for adults, eggs and larvae shows that salinity would not be a barrier to migration from one estuary to another. The chances of the mass migration necessary to maintain the level of uniformity seen in <i>B. improvisus</i> allele frequencies must be very small indeed.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Gene flow between populations of <i>Balanus improvisus</i> Darwin (Cirripedia) in British estuaries","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1989,"MonPub":null,"DateUpdate":"2001-10-04","DateCreate":"2001-08-30","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16949,"PubliDate":1989,"Pagination":"465-472","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":null,"BRefMon":16905,"BRefMonRR":"<b>Ros, J.D.
