This paper describes the within- and between population variability of three closely related marine meiobenthic species of the genus <i>Macrostomum</i> (Macrostomaida). Wild populations and laboratory populations were investigated. For sclerotic hard structures (eg. copulatory stylet), the present study corroborates the very low within population variability as suggested by one earlier study for the same order of Turbellaria. A rise in character variability was seen in laboratory cultures. Unexpected was the low variability of non-sclerotic characters (eg. body length, body width, position of female gonopore and eyes), which generally were thought to vary significantly within populations, but were shown in this study to have less or equal amounts of variation (expressed as coefficient of variability) as the same parameter of hard-bodied meiobenthic species. A general MANOVA, a t-test as well as a stepwise discriminant analysis show that such parameters allow a clear separation of the three investigated species","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Quantification of characters from live observations in meiobenthic Turbellaria-Macrostomida","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":1990,"MonPub":null,"DateUpdate":"2016-03-07","DateCreate":"2004-08-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1990FH86800003","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":65237,"PubliDate":1990,"Pagination":"463-472","XtraPublOfAnaID":null,"ISBN":null,"Volume":"31","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
