The contribution of soil fauna in decomposition processes of areas in the southern part of the
Brazilian Mata Atlântica was studied in three different regeneration stages of lowland and submountain
rainforests. Therefore abundance, biomass and structure of soil macrofauna
communities was determined and the leaf decomposition rates of three plant species (Andira
anthelminthica, Sloanea guianensis and Tibouchina pulchra) assessed by using three different
mesh-sizes of litterbags (0.02, 0.5 mm and 4 mm).
Decomposition of the three leaf species differed strongly. Tibouchina pulchra leaves disintegrated
almost two times faster than the ones of Sloanea guianensis and about three times faster than
Andira anthelminthica. Furthermore it was the only species were leaf decomposition was affected
by soil fauna. Decomposition rates increased from the youngest to the oldest succession stage.
All six sites were very much alike regarding the structure of their soil macro-arthropod communities.
Ants strongly dominated in terms of abundance and biomass, but most are generalists or
predators. They had a negative effect on decomposition rates, probably by influencing the
decomposer community. Abundant decomposers were diplopods and in the older stages also
termites. While beetles occur with high abundances in all sites, due to their minute size they
were not important in terms of biomass. In this regard cockroaches, diplopods and isopods
were most important. Concerning the abundance or biomass of arthropods, neither the two
different forest formations nor the regeneration stages differed considerably and in a way
interpretable as succession. In contrast, abundance and biomass of earthworms, e.g. of the
peregrine species Pontoscolex corethrurus, were much higher in the sub-mountain forests than
in the lowland forests. The different decomposition rates of Tibouchina pulchra in different sites
are well explained by the respective biomass of soil decomposer macrofauna, especially of the
earthworms. MenosThe contribution of soil fauna in decomposition processes of areas in the southern part of the
