Changes in land use alter the structure of bacterial communities in Western Amazon soils

By : Ederson da C Jesus, Terence L Marsh, James M Tiedje and Fatima M de S Moreira

Recent publication from the Brazilian team, published in The International Society for Microbial Ecology (ISME) Journal (2009)

This article shows how agricultural practices by indigenous peoples as well as forest recovery are related to the structure and composition of Amazon soil bacterial communities.

Using T-RFLP and multivariate techniques, the study found that the main differences in bacterial community structure were related to changes in the soil attributes (gradients of base saturation, [Alþ3] and pH) themselves correlated to land use.

The relationship with soil attributes accounted for about 31% of the variation of the studied communities.
