The following demographic parameters were computed from life-table data: the intrinsic rate of natural increase (r<sub>m</sub>) = 0.914 day; net reproductivity (R<sub>0</sub>) = 400; minimum generation time (T<sub>min</sub>) = 4.5 days; cohort generation time (T<sub>c</sub>) = 7.2 days; mean generation time (T) = 6.6 days; and the age of an adult female when a median egg is deposited (T) = 6.1 days. Several approximate equations used to estimate r<sub>m</sub> were compared with these life-table calculations. Some give erroneous estimations and should be used with extreme caution. For iteroparous organisms (including most free-living nematodes), T<sub>min</sub> only gives an indication of the development time and is therefore unsuitable for describing \"mean generation time\".","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Calculation of the intrinsic rate of natural increase, r<sub>m</sub>, with <i>Rhabditis marina</i> Bastian 1865 (Nematoda)","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":1983,"MonPub":null,"DateUpdate":"2019-09-19","DateCreate":"2000-09-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1983TS11600011","VABBcode":null,"OpenAcc":0,"DOI":"10.1163/187529283X00348"},"refs":null,"anarec":{"AnaID":3260,"PubliDate":1983,"Pagination":"468-477","XtraPublOfAnaID":null,"ISBN":null,"Volume":"29","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45095,"SerRR":"Nematologica.
