Oribatid mites (Acari: Oribatida) in the glacier foreland
Hardangerjøkulen glacier (Norway) were investigated. The highest density of mites was observed on the moraine exposed in 1934 (67 years after the glaciers retreat), while the highest number of species (14) was noted on the oldest moraine (206 years after the glaciers retreat). Two species, Tectoceph...

| Summary: | Hardangerjøkulen glacier (Norway) were investigated. The highest density of mites was observed on the moraine exposed in 1934 (67 years after the glaciers retreat), while the highest number of species (14) was noted on the oldest moraine (206 years after the glaciers retreat). Two species, Tectocepheus velatus and Liochthonius lapponicus, were present in all sites. Tectocepheus velatus was relatively abundant on all moraines, while the density of L. lapponicus decreased with moraine age. The population of Camisia horrida (Hermann, 1804), exhibited variability in the occurrence of notogastral setae f 1. This confirmed that C. borealis Thorell, 1871, with setae f 1 in the adult, is a junior synonym of C. horrida. Key words: primary succession, Camisia horrida, notogastral seta, variability |
