Relative effects of biotic and abiotic factors on the composition of soil invertebrate communities in an Amazonian savanna

Using ordinations techniques, we investigated the effects of different types of plant cover on the relationship between soil structure and invertebrate communities in an Amazonian savanna. Vegetation islands were chosen where four selected shrubs species were present on sandy and clayey soils. For e...

Magnusson, William Ernest Luizão, Flávio Jesus Acari Collembola Invertebrata Oribatida Using ordinations techniques, we investigated the effects of different types of plant cover on the relationship between soil structure and invertebrate communities in an Amazonian savanna. Vegetation islands were chosen where four selected shrubs species were present on sandy and clayey soils. For each sample under a selected shrub within the clump, another sample was taken in the grass-tuft and extracted in Berlese-Tullgren. Classifying at higher taxonomic levels, we detected 27 zoological categories. The mean number of individuals was generally higher on shrubs. Acari and Collembola were the dominant groups. Non-Oribatid mites dominated in the savanna, in contrary with what occurs in most Amazonian ecosystems, where the dominance of Oribatida is always higher than others Acari. The level of taxonomic resolution utilized was sufficient to show the main differences of the spatial variation in community structure. We detected effects of soil type, vegetation structure and plant specie identity on the composition of the communities. The mesofauna have a mosaic distribution in the savanna dependent on the soil-food web structure of the vegetation. Shrubs and grass-tuft generate different ecosystems. Therefore, studies with better taxonomic resolution will be necessary to assess the magnitude of the effect of biotic and abiotic factors. © 2005 Elsevier B.V.
