These species are all viviparous. <i>Halisarca dujardini</i> inhabits shallow waters (1.5-5 m); <i>M. incrustans</i> and <i>I. Piceus</i> are common in a more stable environment at depths between 15 and 25 m. Initiation of sexual reproduction stages is dependent upon water temperature. Reproductive effort is low in <i>Myxilla incrustans</i> and <i>I. Piceus</i> (reproductive elements contribute 7.3% and 12% of maternal tissue volume respectively), but much higher in <i>H. dujardini</i> (up to 69% of the parental tissue volume). Reproduction leads to localized destruction of maternal tissue for <i>M. incrustans</i> and <i>I. Piceus</i> and complete disorder of central and basal parts of the choanosoma of <i>H. dujardini</i> after each period of reproduction. <i>Myxilla incrustans</i> and <i>I. Piceus</i> reproduce throughout the hydrological summer, but reproduction in <i>H. dujardini</i> is restricted to 3 weeks. The average life span of <i>M. incrustans</i> and <i>I. Piceus</i> is more than 4 years, and that of <i>H. dujardini</i> is about 7-12 months. The data suggest that <i>M. incrustans</i> and <i>I. Piceus</i> are K-strategists, whereas <i>H. dujardini</i> is an r-strategist.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reproduction cycles and strategies of the cold-water sponges <i>Halisarca dujardini</i> (Demospongiae,Halisarcida), <i>Myxilla incrustans</i> and <i>Iophon piceus</i> (Demospongiae, Poecilosclerida) from the White Sea","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:05.749711","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2003-03-28","DateCreate":"2003-03-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000085606500008","VABBcode":null,"OpenAcc":0,"DOI":"10.2307/1542805"},"refs":null,"anarec":{"AnaID":33537,"PubliDate":2000,"Pagination":"77-87","XtraPublOfAnaID":null,"ISBN":null,"Volume":"198","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42437,"SerRR":"The Biological Bulletin.
