Abundance and diversity of enchytraeids and other microdrile Oligochaeta were studied in
secondary forests, pastures and agroforestry systems in the southern Brazilian Mata Atlântica
(in total: 51 sites) between 2003 and 2008. The investigation is part of the German-Brazilian cooperative
project SOLOBIOMA (www.solobioma.ufpr.br), which monitors rain forest recovery
from degraded areas (mainly pastures) in the Southern Brazilian Mata Atlântica, among other
objectives.
The taxonomic inventory revealed a species richness (up to 20 species per site) and diversity
(up to 6 genera per site) similar to that in temperate regions, even though abundance (1000 -
5000 ind/m2) was consideraby lower than in temperate forest soils where often more than 50000
Ind/m2 are found. Forest sites were species-richest, the bulk belonging to Guaranidrilus spp.;
sites under human influence (pastures, urban parkland) had a different species composition,
with Fridericia and Hemienchytraeus being dominant. Achaeta species differed widely in their
ecological behaviour, some being possibly peregrine, others belonging probably to the old
autochthonous forest fauna. The patterns of response of enchytraeids to forest regeneration
can be characterized as a partial species turnover and an increase in species number with
ongoing succession. It differs form the response observed in megadrile earthworms (see abstract
of Römbke, Schmidt and Höfer), and ants (Bihn et al., 2008, Biol. Conserv., in press) established
in the same project. Ant genera of younger successional stages were a subset of genera present
at older stages and no species turnover was observed, whereas the composition of megadrile
species did not differ among sites. These idiosyncrasies show that it is difficult to derive
generalized statements regarding forest recovery based on one taxonomic group alone.
However, the response patterns of enchytraeids are still far from understood, mainly because
little to nothing is known about the distribution and ecological behaviour of the species, most of
them new to science. MenosAbundance and diversity of enchytraeids and other microdrile Oligochaeta were studied in
