Resumo: | This report gives the result of macrofauna densities and biomasses, for the dry and rainy seasons, in five systems: 1) primary forest; 2) long-term pasture (15 years) (called old pasture); 3) long-term (11 years) abandoned (in 1992) pasture (called pasture degr); 4) short-term ( 5 years) abandoned (in 1987) pasture (called pasture aband); and 5) short-term (5 years) pasture turned to capoeira (in 1987) and then to agrosylvicultural systems in 1991 (called agsosylv.). Preliminary results: a) dry season - macrofauna biomasses and densitiesshowed high differences between plots; b) rainy season - the degraded pasture was notsampled at this date. A few macrofauna groups are dominante in these systems. Other groups less abundant were also present (Diptera larvae, Coleoptera adults and larvae, Arachnida, Mollusca, Hemiptera, Homoptera larvae, Lepidoptera larvae,cockroaches, Orthoptera larvae. Macrofauna densities and biomasses are very different between the rainy season and the dry season and between the five plots.
