A control group and three treated cohorts kept in artificial seawater enriched with nominal concentrations of zinc at 0.25, 0.50 and 1.00 μg Zn/ml, respectively, were considered. Zinc marginally affected survival but had a strong impact on the reproduction of <i>D. gyrociliatus</i>. Zinc enrichment had no effect on age at maturity, whereas it induced a slight increase in fecundity during the early reproductive phases at 0.50 and 1.00 μg Zn/ml, and a sharp decrease in fecundity from the 20th day of life at all levels of metal enrichment tested. Treated groups were characterised by a marked reduction of the net growth rate (R<sub>0</sub>) and a decrease in generation time (T) with respect to the control groups, but no effect on life expectancy (e<sup>0</sup>) or on population growth rates (λ) was observed. R<sub>0</sub> and , which are the most commonly used indices of fitness, were not equally susceptible to zinc.  appears less sensitive to stress induced by metal enrichment with respect to R<sub>0</sub> and other life history traits like age-specific fecundity. <i>D. gyrociliatus</i> appears to be an appropriate bioindicator species in LTRE to assess the consequences of environmental heavy metals on individual life-history and population dynamics.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of zinc exposure on the polychaete <i>Dinophilus gyrociliatus</i>: a life-table response experiment","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:07.468615","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"Life-table response experiments","Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2019-08-29","DateCreate":"2003-09-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000185160000008","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0166-445X(03)00109-7"},"refs":null,"anarec":{"AnaID":39380,"PubliDate":2003,"Pagination":"93-100","XtraPublOfAnaID":null,"ISBN":null,"Volume":"65","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42203,"SerRR":"Aquatic Toxicology.
