18. Avaliação rápida da diversidade de formigas em sistemas de uso do solo no sul da Bahia
We aimed to compare the soil ant diversity in different land use systems from Atlantic Forest area, in Southern Bahia state, Brazil. The ants were sampled in 16 sites: two primary forest sites (un-logged forest); three young secondary forests (<8 years old); three intermediate secondary forests (8-20 years old); three old secondary forests (>20 years old); t

19. Estoques de biomassa e de nutrientes de pousios enriquecidos com Inga edulis Martius em áreas com histórico de agricultura e de pecuária no Assentamento Tarumã-Mirím, Manaus- AM / Stocks of biomass and nutrients in forest fallow enriched with Inga edulis Martius in sites with a history of agriculture and pasture in the rural settlement Tarumã-Mirím, Manaus - AM
Deforestation rates of primary forests in the humid tropics have been growing intensively in recent years, due mainly to the development of shifting cultivation and extensive pasture. After forest fragmentation and conversion to agricultural use, the cleared areas of rainforest are usually abandoned so there is natural regeneration of vegetation and slow res

22. Bioindicadores de qualidade de solo em diferentes ecossistemas
Changes due to soil management and cultivated plant species may influence carbon, nitrogen and phosphorus cycling. Cycling depends on the integration of physical, chemical and mainly microbiological processes. This work assessed some microbial activity and processes related to carbon, nitrogen and phosphorus cycles in soil from six ecosystems in Guarapuava,
