The moss flora was dominated by cosmopolitan and ubiquitous taxa, such as <i>Trinema lineare, T. enchelys, Euglypha laevis</i> and <i>E. rotunda</i>. A cluster analysis and a correspondence analysis identified three communities: (1) a <i>Corythion dubium</i> assemblage found in a drier, slightly acidic terrestrial moss vegetation, (2) the <i>Arcella arenaria</i>, and (3) the <i>Difflugiella crenulata</i> assemblages, both characteristic of wetter, circumneutral habitats. The latter typified submerged mosses growing in running water, while the <i>A. arenaria</i> assemblage seemed to prefer mosses in standing waterbodies. Moisture conditions appeared to play a key role in determining the distribution pattern of testacean communities, while pH was only a secondary factor. A logistic regression emphasised the effect of the habitat type in controlling the variance in testacean assemblages. Moreover, the close relationship between bryophyte species and habitat type had a significant influence on the distribution pattern of the testate amoebae. Weighted averaging and calibration were used to estimate moisture optima and tolerances of the testate amoebae.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The moss dwelling testacean fauna of Île de la Possession","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2004-11-24","DateCreate":"2004-11-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000225050300004","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":68272,"PubliDate":2004,"Pagination":"753-766","XtraPublOfAnaID":null,"ISBN":null,"Volume":"27","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
