Notes
The population dynamics of soil-inhabiting Testacea of 3 experimental plots (1 undisturbed young spruce plot, 2 disturbed meadows) situated in the Tyrolian Centralalps at approximately 1,100 m above sea level were studied. Maximum abundance, biomass and species numbers are found in the upper 2 cm of all examined soils, but there is a distinction between undisturbed and disturbed areas: The disturbance of soil by cultivating causes a significant decrease of the number of specimens. While abundance and biomass decreased with profile depth in the undisturbed soils, there is found a number of specimens in depth b (2-4 cm) which is very similar to that of depth a (0-2 cm) in disturbed areas. The relation disturbed: undisturbed for living Testacea = 1:6.91 (depth a), 1:1.45 (depth b), 1:1.14 (depth c) and this one for empty tests = 1:3.97 (depth a), 1:1.30 (depth b), 1:0.96 (depth c).
