Atraktivita listového opadu pro půdní Collembola v experimentu v dekompozičních síťkách

Collembola play an important role in the decomposition of dead organic matter and in soil microstructure formation. Some Collembola have highly specialised feeding habits. A litterbag experiment was established on the Kleť Mt. (Blanský Les Protected Landscape Area, Czech Republic). Litterbags (100 cm.sup.2./sup.) filled with beech and oak litter were exposed in beech and spruce forests in November 2002. Four forest/liter combinations were exposed - beech-beech, beech-oak, spruce-beech, spruce-oak. Soil samples (10x10x6 cm) for Collembola community structure analysis were taken from each locality. This contribution shows data from the first year of the three-year litterbag experiment. Thirty Collembola species, were established in soil samples from the beech forest, 53 % of them occurred in litterbags with beech litter and 57 % in litterbags with oak litter
