The metabolic cost was high (production: respiration 0.66, versus 2.50 for <i>Nereis</i>), but a greater proportion of the available detritus went into production in <i>Capitella</i> ( trophic transfer efficiency is the ratio between worm production and food supplied; 27% for <i>Capitella</i> and 3% for <i>Nereis</i>). Opportunistic species such as <i>Capitella capitata</i> can exploit high organic conditions as in these laboratory growth studies. They effectively exploit not only by fast population increase when food levels increase, but also by achieving high population densities. The more typical, larger, benthic deposit feeders, such as <i>Nereis succinea</i>, not only have a slower population response to increasing food, but behavioural interactions due to crowding (<i>i.e</i>., increased mortality) may limit population density to levels that do not maximally exploit available food.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Comparison of the ecological energetics of the polychaetes <i>Capitella capitata</i> and <i>Nereis succina</i> in experimental systems receiving similar levels of detritus","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":1982,"MonPub":null,"DateUpdate":"2019-07-04","DateCreate":"2001-07-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":14319,"PubliDate":1982,"Pagination":"46-54","XtraPublOfAnaID":null,"ISBN":null,"Volume":"16","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
