Most of these invasions are linked to the expansion of anthropogenic dispersal mechanisms, such as the worldwide transfer of ballast water through shipping. The construction of artificial hard substrates in the marine environment attracts species that were previously not present. This study focuses on non-indigenous barnacles on groynes in the southern bight of the North Sea. The aim was to map the early phase of invasion and range expansion of <i>Balanus glandula</i>. We determined the present-day geographical distribution of <i>B. glandula</i> on groynes along the entire Belgian coastline and part of the coastline of the Netherlands (i.e. Cadzand), characterized its habitat preference (focusing on tidal zonation and substrate preference) and explored possible competitive interactions with other established barnacle species (i.e. the indigenous <i>Semibalanus balanoides</i> and non-indigenous <i>Elminius modestus</i>). We encountered <i>B. glandula</i> on all ten groynes sampled, which were not equally colonized and showed no East-West gradient in terms of its density. This barnacle had low densities relative to <i>S. balanoides</i> and <i>E. modestus</i> and was most abundant in Raversijde. The most significant environmental variable determining the habitat preference of <i>B. glandula</i> appeared to be the submersion duration. The highest densities were at about 30 to 40% submersion duration, which corresponds to the mid-to-high intertidal zone. <i>Balanus glandula</i> was found on each substrate type, of which conglomerate appeared to be the most preferred, hosting the highest densities. A negative interaction between the recently introduced <i>B. glandula</i> and the indigenous <i>S. balanoides</i> and non-indigenous <i>E. modestus</i> is suggested. However, we concluded from our interspecies regression analysis that our data does not allow to demonstrate a significant effect of <i>B. glandula</i> onto the other two barnacle species. <i>Balanus glandula</i> may affect the intertidal biodiversity in the southern bight of the North Sea, although it is not expected to impact –commercially- important species such as <i>Mytilus edulis</i> (the blue mussel), since this native species occurs towards the sublittoral zone. We conclude that <i>B. glandula</i> has not –yet- displayed its full invasive potential in the southern bight of the North Sea. Yet, due to its competitive advantages, it is very likely that the species will stay here for a longer period of time and possibly will become one of the most abundant barnacle species by outcompeting other barnacles, such as <i>S. balanoides</i> and <i>E. modestus</i>.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"In search of non-indigenous barnacle species on man-made hard substrates in the marine environment (Southern Bight of the North Sea)","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":null,"MonPub":2019,"DateUpdate":"2019-11-05","DateCreate":"2019-09-17","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":316806,"ISBN":null,"PubliDate":2019,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"39","Place":"Antwerpen, Ghent, Brussel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":316806,"InsID":null,"Acronym":null,"FullStandardName":null,"ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":39},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Bouwens","Firstname":"Jan","Initials":"J.","Affiliation":"Oceans & Lakes, Universiteit Gent, UA, VUB","Discriminator":null,"CorporateFlag":0,"BEntID":310134,"AutID":392253,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":"Oceans & Lakes : Master of Marine and Lacustrine Science and Management","ORCID":"0000-0002-0921-4158","PersID":32806,"InsID":11152}],"mapdetails":null,"datasets":null,"monographs":null,"monparts":null,"serparts":null,"BEntOpen":null,"BEntPrivate":null,"availability":[{"BInstID":338797,"LibID":36,"BRefID":316806,"EmbargoDate":null,"FullEmbargoDate":null,"PhysMedID":16,"hasOCRd":1,"ShelfLocCode":"338797","RFID":null,"PaidValue":null,"Medium":"Server","Description":"Interne VLIZ documenten","Acronym":"VLIZ","Library":"Vlaams Instituut voor de Zee","DutchTerm":"Non-open access","URL":null,"ClassifID":228,"Classification":"Non-open access","ReqLink":1,"ClassifTypID":3,"URLLocation":"https://www.vliz.be/imisdocs/publications/","SubDir":1,"InternalReq":1,"LoggedInReq":1,"Disclaimer":"Disclaimer_VLIZ_Intern","DutchDisclaimer":"<p>Deze publicatie is enkel beschikbaar voor persoonlijk gebruik binnen de Innovocean site <br />en mag op geen enkele manier verder worden verspreid.</p>","FileFormat":".pdf","FileDescr":"pdf","InsPub":1,"InsID":36,"FileFormID":6,"LendableFlag":1,"PublicFlag":1,"orderLib":"A","Notes":null,"AccConID":null,"AccessConstraint":null,"LicURL":null}],"litstyles":[{"LitStyID":7,"Style":"Dissertation"}],"thespers":[{"PersID":221,"Surname":"Degraer","Firstname":"Steven","Initials":"S.","Role":"Promotor"},{"PersID":320,"Surname":"Kerckhof","Firstname":"Francis","Initials":"F.","Role":"Co-ordinator"}],"arch2discl":null,"SERpubls":null,"MONpubls":null,"pictures":[],"thestermsPath":null,"thestermsASFA":null,"taxtermsASFA":null,"geotermsASFA":null,"collections":null,"conf":null,"proj":null,"Physdatasets":null,"spcols":{"222":{"SpName":"BMB - Belgische Mariene Bibliografie","SpColID":222,"ParSpColID":null,"TopParID":null,"ShortName":"BMB","URLLocation":null,"LibID":36,"OpenRepoFlag":null,"SpTypID":null,"TopParIDNotWebsite":null,"SpColPath":"BMB"}},"doi":null,"publs":[{"PublID":17795,"PublName":"Oceans & Lakes, Interuniversity Master in Marine and Lacustrine Science and Management","InsID":11152,"PersID":null,"INBOID":null,"OrderNr":1}],"serparttypes":null,"monauthors":null,"MParts":null,"SParts":null,"hLibs":null,"langs":[{"BEntID":310134,"AbstractFlag":0,"LangID":15,"LangCode":"en","Lang":"English","DutchTerm":"Engels","LangCodeExtended":"eng"},{"BEntID":310134,"AbstractFlag":1,"LangID":15,"LangCode":"en","Lang":"English","DutchTerm":"Engels","LangCodeExtended":"eng"}],"urls":null,"thesterms":null,"taxterms":null,"geoterms":null,"othterms":null,"asfacodes":null,"asfa2codes":null,"thestermsFRIS":null,"taxtermsFRIS":null,"geotermsFRIS":null,"othtermsFRIS":null,"resmessage":"","complete":1,"sessions":{"newSesName":"Chisala, Chilekwa, C.","newSesDate":{"date":"2019-09-17 11:47:06.987000","timezone_type":3,"timezone":"Europe/Brussels"},"updSesName":"Verheyde, Fons, F.","updSesDate":{"date":"2019-11-05 08:33:08.303000","timezone_type":3,"timezone":"Europe/Brussels"}}}
