EMBRAPA FLORESTAS | Soil macrofauna communities in native Atlantic Forest fragments and agroforestry systems of different ages the Ribeira River Valley, Brazil

Citation

Description

Soil macrofauna communities were evaluated in a three Atlantic Forest fragments at different stages of regeneration, and in three organic agroforestry systems of different ages in the Ribeira River Valley, Brazil. Sampling was performed in March and August of 2008 in six sites, five of which were located in Barra do Turvo county in São Paulo state, and one in Adrianópolis county in Paraná state. The sites in Barra do Turvo were: a 5, 20 and >30-year-old Atlantic Forest regeneration fragment, and a 4- and 16-year-old organic agroforestry system. In Adrianópolis, only an 8-year-old organic agroforestry system was sampled. Each land use was replicated three times and two samples were taken per plot. Samples were taken using the standard methodology of the Tropical Soil Biology and Fertility Programme (TSBF), where soil (down to 20 cm depth) and litter fauna were hand-sorted from monoliths of 25x25 cm, and the abundance of a total of 42 taxa was assessed.
