In normoxia increasing water temperature from 12 C to18 C reduced by 15 days the median time required for the capsules to hatch. Hypoxia (oxygen content at 50% of air saturation) generated a low development rate and totally prevented both shell secretion and larval hatching from the egg capsule. Experimental transfer at weekly intervals, from normoxia to hypoxia and vice versa, induced a decrease and increase in the embryonic ash content, respectively, but did not affect the number of hatched larvae. Such an effect was more pronounced at 12 C than at 15 Cor18 C. he embryonic inability to produce a shell under hypoxia is likely to be a result of the low intracapsular oxygen concentration (IPO2) generated as the combined effect of a low extra- capsular oxygen concentration (environmental) added to the intracapsular embryonic oxygen demands, which lowers the IPO2 still further. Under such conditions, a decrease in intracapsular pH is likely to take place, and, if so, embryos might divert carbonates away from shell calcification to balance such changes in pH.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Combined effects of dissolved oxygen concentration and water temperature on embryonic development and larval shell secretion in the marine snail <i>Chorus giganteus</i> (Gastropoda: Muricidae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-26 01:31:00.956998","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2019-08-08","DateCreate":"2003-04-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000181017900014","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-002-0925-3"},"refs":null,"anarec":{"AnaID":34304,"PubliDate":2003,"Pagination":"133-139","XtraPublOfAnaID":null,"ISBN":null,"Volume":"142","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
