Succession stages and soil attributes influence the structure of arbuscular mycorrhizal fungi communities in the Atlantic Forest

The objective of this study was to determine the structure, diversity, composition and drivers AMF communities in succession areas Atlantic Forest. Soil root samples were collected three natural ecosystems (mature rainforests, early late secondary forests) with on each ecosystem. In total, 38 taxa identified field more trap cultures a greater richness Acaulospora Glomus. Based estimator, 70% species identified. Highest rates colonization number glomerospores recorded forest. diversity differed between forests. main distribution coarse fine sand, silt, Al, P, Na, pH base saturation. greatest exclusive mature rainforests. influenced by different successional stages some soil attributes.
