SHIFT project ENV 52: soil fauna and litter decomposition. The use of adapted soil biological methods to study macrofauna in Amazonian rain forests. Repositório Alice
GARCIA, M.; HOFER, H.; MARTIUS, C.; ROMBKE, J.; OTT, R.; BECK, L..
A comparative study of litter quantity and quality, decomposition rates, and the abundance, biomass, and respiration of soil-inhabiting microbes, arthropods and oligochaetes has been started in a polyculture forestry plantation and in plots of nearby secondary and primary forest in 1997.

Soil fauna and litter decomposition in primary and secondary forests and a polyculture system in Amazonia - study design and methodology. Repositório Alice
BECK, L.; HOFER, H.; MARTIUS, C.; GARCIA, M. B.; FRANKLIN, E.; ROMBKE, J..
A comparative study of litter quantity and qulity, decompositon rates, and the abundance, biomass, and respiration of soil-inhabiting microbes, arthropods and oligochaetes has been started in 1997. The three study sites are a primary forest, a 13-year old secondary forest and polyculture plantation system consisting of four commercially used tree species planted in rows between adventitious vegetation. The aim is to evaluate the specific contribution of the soil microflora and of the different functional soil fauna groups to the decomposition of organic matter and the resulting nutrient supply to the plants. A general description of the study design of the project is given and some methodological aspects are discussed. Methods that are standard in soil...

The function of the soil macrofauna in decomposition processes in central Amazonian polyculture systems and forests. Repositório Alice
HOFER, H.; BECK, L.; FORSTER, B.; GARCIA, M.; HANAGARTH, W.; LUIZAO, F.; LUIZAO, R.; MARTIUS, C.; MORAIS, J. W.; ROMBKE, J..
A study of macrofauna and decompositon in three central Amazonian ecosystems (a primary and a secondary forest and tow polyculture tree plantations) has shown the high importance of the macrofauna for the litter decompostion. Macrofauna biomass was highest in the primary forest and lowest in the secondary forest. It differed strongly between the two polyculture areas, probably due to different microclimatic conditions near the ground as influenced principally by density of secondary vegetation (cover) and shading by the neighboring forest. Litter decompositon in the central Amazon polycultures follows the same principles than in primary forest, e.g. the macrofauna regulates the decompostion rates. However the structure of the decomposer community differs...

The role of soil fauna in litter decomposition in primary forests, secondary forests and a polyculture plantation in Amazonia - methodological considerations. Repositório Alice
BECK, L.; GASPAROTTO, L.; FORSTER, B.; FRANKLIN, E.; GARCIA, M.; HARADA, A.; HOFER, H.; LUIZAO, F.; LUIZAO, R.; MARTIUS, C.; MORAIS, J. W. de; ROMBKE, J..
A comparative study of litter quantity and quality, decomposition rates, and the abundance, biomass, and respiration of soil-inhabiting microbes, arthropods and oligochaetes in a polyculture forestry plantation and in plots of nearby secondary and primary forests. The aim is to evaluate the specific contribution of the soil microflora and of the different function soil fauna groups to the decompostion of organic matter and the resulting nutrient supply to the plants. Several methods for the study of the soil fauna and microflora have been adapted to neotropical conditions on the base of preliminary tests.
