Abstract: [eng] [cze]
The effect of gut passage by three earthworm species (.i.Lumbricus rubellus, Dendrobaena octaedra, Dendrodrilus rubidus./i.) on the structure of ingested clay minerals was studied using X ray powder diffractometery. No differences were found in the peak's positions in diffraction spectra of clay spoil and clay in earthworm casts, indicating no changes in clay lamella inter-spacing. Differences were found in the peak's sizes, which seem to be caused by changes in preferential orientation of clay minerals during gut passage. Byl sledován vliv průchodu střevem 3 druhů žížal (.i.Lumbricus rubellus, Dendrobaena octaedra, Dendrodrilus rubidus./i.) na strukturu jílových minerálů pomocí rentgenové práškové spektrofotometrie. Nebyly nalezeny žádné rozdíly v poloze vrcholů difrakčních spekter, rozdíly ve velikosti vrcholů byly nejspíše způsobeny změnou v preferenční orientaci jílových lamel.
