Abstract
In this communication data are presented concerning absolute abundance, soil surface activity and flight activity of Carabid beetles in a heavily grazed pasture. During a two year cycle intensive sampling was therefore performed by means of different techniques.Maximal yearly abundance values are rather high and reach values from 1 to 17 individuals per meter square according to the species concerned. Flight activity on the other hand only occurred occasionally and the relative amount of flight activity per unit of soil surface activity was negatively related to estimated abundances.Zusammenfassung: Die Beziehung zwischen Abundanz und Flugaktivität bei Carabiden eines Grünlands unter intensiver BeweidungIn einem 2jährigen intensiven Feldversuch mit verschiedenen Methoden wurden in einen Grünland unter intensiver Beweidung die absolute Abundanz, epigaïsche Aktivität und Flugaktivität bei Carabiden untersucht.Die jährliche maximale Abundanz erreichte Werte von 1–17 Individuen pro m2 entsprechend den einzelnen Arten. Dagegen war die Flugaktivität gering. Es wurde eine negative Relation zwischen der relativen Flugaktivität (pro epigaïsche Aktivität) und der absoluten Abundanz festgestellt.This publication has 17 references indexed in Scilit:
