Apoidea (except Apidae) on the northern slopes of the Hohe Tauern Mts.

• Mirosława DYLEWSKA

Abstract:

Ninety-five apoidean species (except Apidae) have been identified from the northern slopes of the Hohe Tauern Mts. In these mountains a distinct faunistic boundary (1400 m) extends about 200 m above the boundary of summer in the climatic sense of the word and about 70% of the apoidean species do not go beyond it. They include all the submediterranean and south central European and most of the summer species. The highest-lying sites of the fauna under study, except Andrena rogenhofferi, occur close to the upper boundary of late spring i n the climatic sense (potential timber-line) at an altitude of about 2100 m. In the Tatra Mts these two faunistic boundaries run about 500 m lower, however, they remain there in the same relation to the climatic boundaries as in the Hohe Tauern Mts.
