These species occur naturally along a contamination gradient of cadmium, copper, lead and zinc, in a Norwegian Fjord (Sørfjord). Sperm motility was quantified with the help of a computer assisted sperm analysis system (CASA). The RNA/DNA ratios were assessed based on a l-dye, (Ethidium bromide)/l-enzyme (RNase) 96-well microplate fluorometric assay. Although both species appeared to readily accumulate metals, neither sperm motility parameters in A. rubens nor RNA/DNA in the body wall of both species were affected. The RNA/DNA ratios in A. rubens pyloric caeca were significantly higher in the most contaminated station. Even thought this fjord is considered a highly contaminated place, these populations seem to tolerate these metal contamination levels.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"Effects of field metal contamination on sperm motility and RNA/DNA ratio in two echinoderm species = Efeito da acumulação de metais pesados na motilidade do esperma e no índice ARN/ADN de populações de duas espécies de equinodermes","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-05-09 01:32:46.834590","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2006,"DateUpdate":"2025-05-02","DateCreate":"2025-05-02","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"Handle":"10174/16151"},"refs":null,"anarec":null,"monrec":{"MonID":407796,"ISBN":null,"PubliDate":2006,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"13","Place":"Lisboa","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MA","ThesisID":407796,"InsID":null,"Acronym":null,"FullStandardName":null,"ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":13},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"dos Ramos Catarino","Firstname":"Ana Isabel","Initials":"A.I.","Affiliation":null,"Discriminator":null,"CorporateFlag":0,"BEntID":405597,"AutID":564348,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":null,"ORCID":"0000-0002-8796-0869","PersID":38251,"InsID":null}],"mapdetails":null,"datasets":null,"monographs":null,"monparts":null,"serparts":null,"BEntOpen":null,"BEntPrivate":null,"availability":[{"BInstID":413492,"LibID":36,"BRefID":407796,"EmbargoDate":null,"FullEmbargoDate":null,"PhysMedID":16,"hasOCRd":1,"ShelfLocCode":"413492","RFID":null,"PaidValue":null,"Medium":"Server","Description":"VLIZ Open Access","Acronym":"VLIZ","Library":"Vlaams Instituut voor de Zee","DutchTerm":"Open access","URL":null,"ClassifID":53,"Classification":"Open access","ReqLink":null,"ClassifTypID":1,"URLLocation":"https://www.vliz.be/imisdocs/publications/","SubDir":null,"InternalReq":0,"LoggedInReq":0,"Disclaimer":null,"DutchDisclaimer":null,"FileFormat":".pdf","FileDescr":"pdf","InsPub":1,"InsID":36,"FileFormID":6,"LendableFlag":null,"PublicFlag":1,"orderLib":"A","Notes":null,"AccConID":null,"AccessConstraint":null,"LicURL":null}],"litstyles":[{"LitStyID":7,"Style":"Dissertation"}],"thespers":[{"PersID":203,"Surname":"Dubois","Firstname":"Philippe","Initials":"P.","Role":"Promotor"}],"arch2discl":null,"SERpubls":null,"MONpubls":null,"pictures":[],"thestermsPath":null,"thestermsASFA":null,"taxtermsASFA":null,"geotermsASFA":null,"collections":null,"conf":null,"proj":null,"Physdatasets":null,"spcols":null,"doi":null,"publs":[{"PublID":30528,"PublName":"Universidade de Évora","InsID":6132,"PersID":null,"INBOID":null,"OrderNr":1}],"serparttypes":null,"monauthors":null,"MParts":null,"SParts":null,"hLibs":null,"langs":[{"BEntID":405597,"AbstractFlag":0,"LangID":15,"LangCode":"en","Lang":"English","DutchTerm":"Engels","LangCodeExtended":"eng"},{"BEntID":405597,"AbstractFlag":1,"LangID":15,"LangCode":"en","Lang":"English","DutchTerm":"Engels","LangCodeExtended":"eng"}],"urls":[{"URL":"https://hdl.handle.net/10174/16151","externalID":"10174/16151","URLTypeCode":"Handle","URLID":145656,"URLTypID":32,"URLType":"Handle","URLPrefix":"https://hdl.handle.net/"}],"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":"2025-05-02 08:14:38.410000","timezone_type":3,"timezone":"Europe/Brussels"},"updSesName":"Chisala, Chilekwa, C.","updSesDate":{"date":"2025-05-02 08:14:38.410000","timezone_type":3,"timezone":"Europe/Brussels"}}}
