bioindication of different stages of eutrophication<br />
3.7. Role of earthworms in the bioindication of the pine forest eutrophication<br />
processes<br />
Changes of earthworm fauna reflect the soil processes. Earthworm<br />
communities are sensitive to the forest transformation processes, forming species<br />
complexes appropriate for the soil and forest growth condition type. Also changes<br />
earthworm density, ecological groups, species structure and dominance structure<br />
((Bauchhenβ, 2006). Earthworms are an appropriate soil animal group in the nonspecific<br />
bioindication of oligotrophic pine forest transformation (eutrophication).<br />
Dynamics of the earthworm species and changes of the species structures, very<br />
well reflect complex biocenotic changes due to both the increase of forest recreation<br />
loads and the calcium pollution. As researches in Jurmala and Saulkalne transect<br />
soils show, changes in earthworm communities are detected before the fitocenotic<br />
