Legacy of Amazonian Dark Earth soils on forest structure and species composition
Global Ecology and Biogeography, Volume 29, Issue 9, Page 1458-1473, September 2020., 2020 Abstract Aim Amazonian forests predominantly grow on highly weathered and nutrient poor soils. Anthropogenically enriched Amazonian Dark Earths (ADE), traditionally known as Terra Preta de Índio, were formed by pre‐Columbian populations. ADE soils are characterized by increased fertility and have continued to be exploited following European ...

Environmental Controls on the Riverine Export of Dissolved Black Carbon
Global Biogeochemical Cycles, Volume 33, Issue 7, Page 849-874, July 2019., 2019 Abstract Each year, tropical rivers export a dissolved organic carbon (DOC) flux to the global oceans that is equivalent to ~4% of the global land sink for atmospheric CO2. Among the most refractory fractions of terrigenous DOC is dissolved black carbon (DBC), which constitutes ~10% of the total DOC flux and derives from the charcoal and soot (aerosol)
