Stage durations were determined by two different methods, using synchronous cohorts. Combined nauplius stages last for 80.4h; the successive copepodite stages take 23.0, 23.2, 28.0 (females) to 23.2 (males), 33.4 (females) to 24.2 (males) and 48.8 (females) to 34.7 (males) h, respectively. Females develop more slowly but more synchronously than males. Age-specific survival and fertility rates were used to calculate the stable stage distribution in an exponentially growing population. From life-table data the following demographic parameters were computed: intrinsic rate of natural increase <i>r<sub>m</sub></i> = 0.233 day<sup>-1</sup>; net reproductive rate <i>R<sub>0</sub></i> = 94; minimum generation time <i>T<sub>min</sub></i> = 14.9 days; parameters related to \"generation time\": <i>T</i> = 19.5 days, <i>T(mean)</i> = 16.4 days, <i>T<sub>e</sub></i> = 25.4 days.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A demographic study of the life cycle of <i>Tisbe furcata</i> (Baird, 1837) (Copepoda: Harpacticoida)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-27 01:31:13.259558","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1981,"MonPub":null,"DateUpdate":"2003-01-07","DateCreate":"2000-09-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1981LZ91400011","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S0025315400048141"},"refs":null,"anarec":{"AnaID":3705,"PubliDate":1981,"Pagination":"691-705","XtraPublOfAnaID":null,"ISBN":null,"Volume":"61","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43277,"SerRR":"Journal of the Marine Biological Association of the United Kingdom.
