Both species are adapted to exploit patches with high densities of bacteria such as decaying particulate matter. When growing cells of <i>Uronema</i> are deprived of food, the cells undergo from one to three cell divisions and form motile swarmer cells. These have a high motility and a long survival, but when refed they need a long lag time before they resume cell divisions. This reflects cell physiological change and reduction in metabolic rate during starvation and so the cost of long term survival. This ciliate is particularly adapted to exploit food resources with a patchy spatial distribution. <i>Pseudocohnilembus</i> cells do not divide when starved; instead they form motile swarmer cells and these can resume cell divisions quickly when food is available, but their survival time is only approximately equals 1/3 of that of <i>Uronema</i> cells. However, about half of the <i>Pseudocohnilembus</i> swarmers are capable of forming resting cysts 10-30 h after the onset of starvation.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Adaptive significance of polymorphic life cycles in protozoa: responses to starvation and refeeding in two species of marine ciliates","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:32:52.928458","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2009-06-16","DateCreate":"2009-06-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":137291,"PubliDate":1990,"Pagination":"159-177","XtraPublOfAnaID":null,"ISBN":null,"Volume":"136","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43229,"SerRR":"Journal of Experimental Marine Biology and Ecology.
