Abstract
Summary In two groundwater canals of a water work in West Germany the drift of stygobiont groundwater organisms was investigated. The collections were made at two-hour intervals. Niphargus aquilex Schiödte, Crangonyx subterraneus Bate and Graeteriella unisetigera (Graeter) were considered more closely, because they were caught in greater numbers than other organisms. These stygobionts show no sign of diel periodicity. Zusammenfassung In zwei unterirdischen Kanälen, die Grundwasser aus Sickergallerien zu einem Wasserwerk in Wiesbaden leiten, wurde die Drift von stygobionten Grundwassertieren untersucht. Die Entnahme von Proben wurde in 2-Stunden-Intervallen ausgeführt. Niphargus aquilex Schiödte, Crangonyx subterraneus Bate und Graeteriella unisetigera (Graeter) fanden besondere Berücksichtigung. Bei diesen 3 stygobionten Grundwassertieren waren keine Anzeichen eines tageperiodischen Verhaltens zu erkennen.
