The numbers of infested snails were hereafter reduced by an amount equal to the observed mortality rate of snails. At the same time, the <em class=\"a-plus-plus\">C. volutator</em> population became extinct. Since other conceivable mortality factors could be ruled out, parasites are suspected to be the causative agent. Apart from the expected effects on potential predators by the decline in the two invertebrate populations, the benthic community changed and destabilization of the substratum occurred probably because of the die-off in <em class=\"a-plus-plus\">C. volutator</em>. Meteorological data suggest high temperatures as a triggering factor of the massdevelopment of the studied trematodes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Mass mortality in two common soft-bottom invertebrates, <i>Hydrobia ulvae</i> and <i>Corophium volutator</i> - the possible role of trematodes","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:31:25.066142","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1992,"MonPub":null,"DateUpdate":"2014-09-26","DateCreate":"2014-09-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1992KE31900006","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/BF02367103"},"refs":null,"anarec":{"AnaID":241490,"PubliDate":1992,"Pagination":"0174-3597","XtraPublOfAnaID":null,"ISBN":null,"Volume":"46","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43116,"SerRR":"Helgoländer Meeresuntersuchungen.
