The abundance, biomass and diversity of several species of peregrine earthworms belonging
to different families (Glossoscolecidae, Megascolecidae, Ocnerodrilidae) were sampled in
secondary forests, pastures and agroforestry systems in the southern Brazilian Mata Atlântica
(in total: 51 sites) between 2003 and 2008. Each site was sampled once, using partly a
combination of hand-sorting and formol extraction, partly only hand-sorting (ISO 2006). At each
site five quadrates (50 * 50 cm) were dug out to a depth of 10 - 20 cm before a 0.5% aqueous
formol solution was poured into each hole. All worms were stored in 70% ethanol before counted,
weighed and determined to the species level. The study sites are situated in the coastal area of
the Serra do Mar near the town of Antonina, within and adjacent to the Protection Area (EPA) of
Guaraqueçaba. Among the diverse soil types occurring in the region, Podzols, Cambisols and
Gleysols are abundant. We studied secondary forests of four different age stages in two different
forest formations (Restinga, sub-mountain forest), two different agroforestry systems and
pastures. The investigation is part of the German-Brazilian co-operative project SOLOBIOMA
(www.solobioma.ufpr.br). Objective of this study was to clarify whether different forest formations
and regeneration stages of secondary forest show characteristic earthworm assemblages and
which site properties (e.g. vegetation type, soil type, land use history) determine their structure
(abundance, biomass and diversity).
Species diversity of the earthworms was generally low and did not differ between the sites. Only
five species, all peregrine, are regularly found. At almost all sites Pontoscolex corethrurus strongly
dominated the samples. Very moist sites, e.g. close to small creeks, showed higher proportions
of Amynthas (2 species) or Ocnerodrilus occidentalis. Abundance and biomass of earthworms
varied a lot within and between sites. No worms were found in the sandy soil of a very young
forest close to the beach, while up to 300 ind m-2 occurred in some pastures as well as in
agroforestry sites. These results indicate that the whole region has already been altered by
man. Obviously all endemic earthworm species have been replaced by peregrine invasive
species, originating from Northern South America (i.e. P. corethrurus) or South-Eastern Asia
(Amynthas spp.). The often very high abundance and, in particular, biomass (by far the biggest
part of the whole soil invertebrate community) underlines their important role for the provision of
ecological services. However, in detail the contribution of these worms to processes like, for
example, organic matter decomposition, are far from understood.
