Abstract
Water beetle species assemblages were sampled from 199 sites in drains generally associated with arable farming in eastern England. The major factors affecting the distribution of species assemblages were pH and conductivity, identified using DECORANA and CANOCO. It was, however, difficult to identify from the measurements taken which factors were specifically responsible for differences between the eight habitat groups interpreted using TWINSPAN. The beetle species present provided a better measurement of habitat type than a series of “spot” measurements of physical and chemical variables.Zusammenfassung: Über Faktoren, die die Verbreitung von Wasserkäfergemeinschaften in Abflußgräben im östlichen England bestimmenAn 119 Orten in Ackerbaugegenden Ostenglands wurden die Wasserkäfergemeinschaften in Abflußkanälen festgestellt. Die die Verbreitung der Käfergemeinschaften hauptsächlich beeinflussenden Faktoren waren der pH‐Wert und die Leitfähigkeit. Gesichert wurden die Ergebnisse mittels der Analyseverfahren DECORANA und CANOCO. Es erwies sich als schwierig, aus den Messungen die für die Differenzen zwischen den 8 Habitat‐Gruppen (unterschieden nach der Artenanalyse TWINSPAN) verantwortlichen Faktoren zu bestimmen. Die Anwesenheit bestimmter Käferarten bildete eine bessere Bestimmungsgrundlage für den Habitat‐Typ als eine Serie von “spot”‐Messungen physikalischer und chemischer Variablen.This publication has 11 references indexed in Scilit:
