Abstract

Enchytraeidae were studied at spruce forest sites (Harz, Germany) differing in their exposure and soil acidity affected by acid deposition. Total density ranged between 38000 and 59000 ind. m-2 and biomass between 0.5 and 1 g m-2 d.m. (annual means). Of the seven species recorded, Cognettia sphagnetorum, Marionina clavata, and Achaeta camerani were dominant. The site affected most by acidification had the highest densities and lowest species number. Population dynamics and vertical distributions were affected by climate. Field and laboratory data provide evidence for sexual reproduction of C. sphagnetorum. Substrate preference experiments showed this species to prefer spruce litter from the OL-Horizon to that from the OH-Horizon, and spruce litter to beech litter.

Abstract (in Czech)

V německém pohoří Harz byly studovány roupice ve smrkových porostech lišících se svou expozicí a kyselostí půdy ovlivňované kyselou depozicí. Celkové hustoty kolísaly mezi 38000 a 59000 ind. m-2 a biomasa mezi 0.5 and 1 g m-2 suché váhy (roční průměry). Ze sedmi zjištěných druhů byly dominantní Cognettia sphagnetorum, Marionina clavata a Achaeta camerani. Lokalita nejvíce postižena okyselením vykazovala nejvyšší hustoty a nejnižší počet druhů. Populační dynamiky a vertikální rozmístění byly ovlivněny klimatem. Data z terénu i laboratorních pokusů dokládají pohlavní rozmnožování druhu C. sphagnetorum. Experimenty k preferenci substratu ukázaly, že tento druh dává přednost smrkovému opadu z OL-horizontu oproti témuž z OH-horizontu a rovněž smrkový opad oproti bukovému.
