N2 - The Restinga is one of the ecosystems of the Atlantic Rainforest biome in Brazil. It is characterized by extremely nutrient-poor soils formed in sandy coastal sediments from the Quaternary age. The highly dynamic environment of sandy coasts causes landforms with different microrelief. This, in combination with the poor and harsh conditions strongly influence both vegetation composition and ecological succession. Consequently soil formation and vegetation has remarkable variation at short distances within the Restinga ecosystem. This variation strongly depends on (i) geomorphological evolution (deposition/ erosion and age), (ii) particle size of the sediment (sand or clay), (iii) drainage conditions, and (iv) organic matter inputs. Soils from the Restinga ecosystem include Espodossolos (Podzols), Neossolos Quartzarênicos (Arenosols), Organossolos (Histosols), and Gleissolos (Gleysols). However, poorly drained Espodossolos (Podzols) dominate this forested landscape due to the low and flat relief of the shoreline and large amounts of dissolved organic matter (DOM) produced upon decomposition of litter and roots in H, O, and A horizons. The morphology of Espodossolos in the Restinga ecosystem is complex, with a large short-distance variability in depths and shapes of the E- and B-horizons. In order to interpret soil-forming processes in the context of the landscape, transects of related profiles are studied in detail in the different geomorphic units. We connect soil morphology, micromorphology, organic matter chemistry, and microbiology with geomorphology at the ecosystem level.
