Indicator values, strategy types and life forms of terrestrial Enchytraeidae and other microannelids

The ecological behaviour of soil microannelid species, mainly Enchytraeidae, is characterized, using the system of indicator values established for plants by Ellenberg (1992), and modifying it for annelids. The species are classified with respect to pH, soil moisture, salinity, reproductive strategy, stress tolerance, and their occurrence in the continuum of humus horizons and humus forms. The values given apply to the situation in Central Europe.
