Concerning life tables the number of female offspring born in each time interval V<sub>x</sub>, net reproductive rate R<sub>o</sub>, survival-fecundity rates of increase r<sub>s</sub>, finite rate of increase <i>lambda</i>, potential to double the population Y, and mean generation time T, was calculated. Values obtained indicated the better condition of Atlantic stock. Analysis of growth rates in pups from Patagonia and Antarctica belonging to the Atlantic stock showed significant differences in birth weight, the higher value corresponding to Antarctica. As a consequence of that, analysis of adult length frequency showed that these differences were retained in the adult stages. Relationship between mother size, pups' growth and milk composition were analysed and an index for monitoring interannual changes in growth rate was presented. Possible link of the decline with food availability are discussed.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"Searching for causes of Southern Elephant Seal populations decline","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":1996,"DateUpdate":"2011-10-26","DateCreate":"2001-07-05","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":12917,"ISBN":null,"PubliDate":1996,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"57","Place":"Brussel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":12917,"InsID":33,"Acronym":"ECOL","FullStandardName":"Vrije Universiteit Brussel; Faculteit Wetenschappen; Vakgroep Biologie; Laboratorium voor Ecologie en Systematiek","ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":57},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Stanganelli","Firstname":"Zulma Béatriz","Initials":"Z.B.","Affiliation":null,"Discriminator":null,"CorporateFlag":0,"BEntID":12917,"AutID":16806,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":null,"ORCID":null,"PersID":null,"InsID":null}],"mapdetails":null,"datasets":null,"monographs":null,"monparts":null,"serparts":null,"BEntOpen":null,"BEntPrivate":null,"availability":[{"BInstID":227526,"LibID":36,"BRefID":12917,"EmbargoDate":null,"FullEmbargoDate":null,"PhysMedID":16,"hasOCRd":1,"ShelfLocCode":"227526","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":51,"Surname":"Daro","Firstname":"Marie Hermande","Initials":"M.H.","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":{"5":{"SpName":"Belgian theses on marine topics","SpColID":5,"ParSpColID":396,"TopParID":396,"ShortName":"Belgian marine theses","URLLocation":null,"LibID":null,"OpenRepoFlag":0,"SpTypID":null,"TopParIDNotWebsite":396,"SpColPath":"vliz:biblio/Belgian marine theses"},"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"},"396":{"SpName":"VLIZ Bibliographies","SpColID":396,"ParSpColID":null,"TopParID":null,"ShortName":"vliz:biblio","URLLocation":null,"LibID":null,"OpenRepoFlag":null,"SpTypID":null,"TopParIDNotWebsite":null,"SpColPath":"vliz:biblio"}},"doi":null,"publs":[{"PublID":2005,"PublName":"VUB","InsID":2956,"PersID":null,"INBOID":6227,"OrderNr":1}],"serparttypes":null,"monauthors":null,"MParts":null,"SParts":null,"hLibs":null,"langs":[{"BEntID":12917,"AbstractFlag":0,"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":"VLIZ2000\\fei","newSesDate":{"date":"2001-07-05 08:26:27.510000","timezone_type":3,"timezone":"Europe/Brussels"},"updSesName":"Haspeslagh, Jan, J.","updSesDate":{"date":"2011-10-26 13:20:29.740000","timezone_type":3,"timezone":"Europe/Brussels"}}}
