“…The exchangeable cations Ca 2+ , Mg 2+ , and Al 3+ were extracted using a 1 mol L -1 KCl solution. The Ca 2+ and Mg 2+ contents were determined in the extract by titration with EDTA 0.01 mol c L -1 , and the Al 3+ contents by titration with NaOH 0.025 mol c L -1 , according to Silva et al (1999). The elements P, K, Zn, Fe, Mn, and Cu were extracted by the Mehlich 1 solution, the sulphur (S), by a solution of monocalcium phosphate in acetic acid, and the contents of these elements in the extracts were determined by spectrophotometry, according to Silva et al (1999).…”

Habitat loss and fragmentation have been impacting ecosystem services essential for human survival. The Brazilian Atlantic rainforest, a biodiversity hotspot, has suffered from historical deforestation and, more recently, from an environmental disaster caused by the Fundão dam collapse that released ore tailings drastically affecting a large territory in the Doce River watershed. This work aims to assess the relationships between soil properties and vegetation in a reference ecosystem to provide guidelines for restoration projects in areas affected by the dam collapse. We conducted phytosociological (vegetation characteristic) and soil quality studies in three distinct natural sites and studied different vegetation strata to better understand plant species composition in reference sites along the impacted Doce River and their potential role in community structuring and functioning. We recorded 140 species, 78 in the tree stratum, and 90 in the sapling stratum. Furthermore, our results highlight the influence of soil on floristic composition in the Atlantic rainforest. Smallscale edaphic variation influenced species composition in both sapling and tree strata. We also identified species of the same genus with strong association with the extremes of the edaphic gradient. Therefore, we highlight that studies in various regions along the Doce River watershed are of utmost importance to evaluate the association between species and soils. The particularities of the species are crucial to the effectiveness of restoration processes since this plant-soil correlation should not be extrapolated even within the same genus. This knowledge is of strategic relevance to provide scientificbased guidance for restoring these environments, aiming at the recovery of biodiversity and ecosystem services.
