EMBRAPA FLORESTAS | Soil macrofauna communities in native Atlantic Forest fragments with different disturbance levels in Londrina, Paraná, Brazil

Citation

Description

Soil macrofauna communities were evaluated in a three semi-deciduous seasonal Atlantic Forest fragments with different levels of disturbance in Londrina, Paraná, Brazil. Sampling was performed in August and December 2005 at the Mata dos Godoy State Park (least disturbed, primary forest), Arthur Thomas Municipal Park (intermediate disturbance; intermediate regeneration stage) and the Horto Florestal of the Universidade Estadual de Londrina (most disturbed; initial regeneration stage). In each forest fragment, 25 samples were taken in a square grid of 5x5 samples, with 10 m between sampling points. Of the total, five samples (along the diagonal) were taken down to 30 cm depth, and the remaining only to 0-10 cm depth. Samples were taken using the standard methodology of the Tropical Soil Biology and Fertility Programme (TSBF), where soil and litter fauna were hand-sorted from monoliths of 25x25 cm, and the abundance of a total of 42 taxa was assessed.
