Ethanol, formaldehyde, and Bouin were used as preservative. In case of preservation of macro-invertebrates in ethanol substancial changes in DW and AFDW biomass were observed. In the four different taxa the loss in DW varied between 7.2–21.9% after a 3 month preservation period in 70% ethanol. A comparatively small range in AFDW loss (16.2–19.7%) was found. Changes in DW and AFDW biomass during preservation were significantly affected by the duration of the preservation, by temperature, light conditions and the volume of the preservative. The changes in AFDW were also significantly affected by the concentration of the preservatives. Preservation in 10% formaldehyde did not cause significant changes in DW and AFDW biomass.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of preservation on dry- and ash-free dry weight biomass of some common aquatic macro-invertebrates","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":2004,"MonPub":null,"DateUpdate":"2014-11-21","DateCreate":"2008-06-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1985AQZ4600005","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":123406,"PubliDate":2004,"Pagination":"151-159","XtraPublOfAnaID":null,"ISBN":null,"Volume":"127","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42943,"SerRR":"Hydrobiologia.
