Stydy at a laboratory to investigate the effects of litter from different species (Theobroma grandiflorum - cupuacu, Bactris gasipaes - pupunha, Bertholletia excelsa - castanha-do-Para, Bixa orellana - urucum, Pueraria phaseoloides - pueraria) and fertilization with N and P on C, N and P in microbial biomass of the topsoil (0cm-5cm) with high organic C contents and of an underlying horizon (10cm-15cm) with low organic C contents of a Xanthic Ferrasols, in Manaus-AM (Brasil).

Soil fauna and litter decomposition in primary and secondary forests and a mixed culture system in Amazonia.

Autores: SHIFT PROJECT ENV 52.
The first months of the year were dedicated to preparatory work in Germany and in Brazil. In July we finished the unexpectedly time-and cost-intensive installation of a generator and no break system to maintain the functioning of extraction and analyzing equipment (Kempson and Berlese-extractor, C/N-analyzer and Infra-Red-Gasanalyzer IRGA) during the very frequent breakdowns of the power supply in the laboratory of the EMBRAPA institute. On 23/24 July the joint "central sampling program of macro-and mesofauna, oligochaeta and microflora which includes field and laboratory work was successfully tested. On 27 october the first litterbag series with 1008 litterbags containing air-dried Vismia-litter to evaluate site-specific decomposition rates was...

Soil fauna and litter decomposition in primary and secondary forests and a mixed culture system in Amazonia.
Provedor de dados: 14
Autores: SHIFT PROJECT ENV 52 (Manaus-AM).
Estudo sobre a fauna do solo e decomposicao da serapinheira feito em tres diferentes ecossistemas na Amazonia central: (1) floresta primaria (FLO), (2) floresta secundaria (SEC), e (3) duas parcelas de cultivo misto (POA, POC). As pesquisas incluiram a avaliacao da producao e estoque de serapilheira, parametros do solo, fatores microclimaticos, abundancia e biomassa da fauna do solo, determinacao da respiracao no solo e biomassa microbiana, medidas das taxas de respiracao dos componenetes da fauna, e analises de micronutrientes. Apesar das diferencas observadas entre as areas de estudo, foi observado que em todas elas o sistema de decomposicao da serapilheira foi controlado pela macrofauna, e que, em todos os sistemas de cultivo estudados, as condicoes...

Soil termites in primary forest, secondary forest and an agroforestry plantation system in central Amazonia.
Provedor de dados: 14
Autores: MARTIUS, C.; GOMES, E.; GARCIA, M. V. B.
Litter and soil termites were collected with soil cores (21cm diameter) in a primary forest site, a secondary forest site and two sites of a polyculture plantation system in central Amazonia (Brazil), in three-monthly intervals from 1997 to 1999. Termite genus diversity, abundance and biomass all were highest in the primary forest. The values in the secondary forest were half those of the primary forest, and they were lowest in the plantation systems, indicating that the latter sites may suffer from functional constraints concerning the process of organic residue decomposition.

Biomass and nutrient cycling in pure and mixed stands of native tree species in southeastern Bahia, Brazil
Provedor de dados: 90
Autores: Gama-Rodrigues,Antonio Carlos da; Barros,Nairam Félix de; Comerford,Nicholas Brian.
The objective of this paper is to study selected components of the nutrient cycle of pure and mixed stands of native forest species of Atlantic Forest in southeastern Brazil. Tree diameter, height, above-ground biomass, and nutrient content were determined in 22-year-old stands. Litterfall, litter decomposition, and nutrient concentration were evaluated from August 1994 to July 1995. The following species were studied: Peltogyne angustiflora, Centrolobium robustum, Arapatiella psilophylla, Sclerolobium chrysophyllum, Cordia trichotoma, Macrolobium latifolium. The litter of a natural forest and a 40-year-old naturally regenerated second-growth forest was sampled as well. The mixed-species outmatched pure stands in height, stem volume and total biomass (29.4...
