Here we report on the further spread of this invasive ctenophore from the south-western towards the central Baltic Sea up to the south eastern Gotland Basin during autumn/winter 2006 and spring 2007. The abundances were generally low (max. 4 ind. m<sup>-3</sup>). While <i>M. leidyi</i> was located in the entire water column in Kiel Bight, it was found exceptionally below the halocline in the deep stratified central Baltic basins. Data of a weekly sampling program at a near shore sampling location in Mecklenburg Bight between January and May 2007 showed that up to 80 % of the individuals were juveniles, smaller than 1 mm total body length and that <i>M. leidyi</i> survived the winter in the Southern Baltic Sea, even if abundances dropped down to <1 ind. m<sup>-3</sup> in February. A first assessment of the physiological demands of this species versus the environmental conditions of the Baltic Sea showed that the successful establishment of this ctenophore is probable in the south-western and central Baltic Sea.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>Mnemiopsis leidyi</i> in the Baltic Sea: distribution and overwintering between autumn 2006 and spring 2007","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2007,"MonPub":null,"DateUpdate":"2012-05-08","DateCreate":"2008-03-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.3391/ai.2007.2.2.9"},"refs":null,"anarec":{"AnaID":120679,"PubliDate":2007,"Pagination":"137-145","XtraPublOfAnaID":null,"ISBN":null,"Volume":"2","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":97172,"SerRR":"Aquatic Invasions.
