Drought-induced Amazonian wildfires instigate a decadal-scale disruption of for...
Silva, Camila V.J.; Aragao, L. E.O.C.; Barlow, Jos; Espírito-Santo, Fernando; Young, Paul J.; Anderson, Liana Oighenstein; Berenguer, ErikaDrought-induced wildfires have increased in frequency and extent over the tropics. Yet, the long-term (greater than 10 years) responses of Amazonian lowland forests to fire disturbance are poorly known. To understand post-fire forest biomass dynamics, and to assess the time required for fire-affected forests to recover to pre-disturbance levels, we combined 16 single with 182 multiple forest census into a uniqu...
Mercury in soils and sediments from gold mining liabilities in Southern Amazonia
Wasserman, Julio Cesar; Campos, Reinaldo Calixto; Hacon, Sandra de Souza; Farias, Renato A.; Caires, Sandro M.The 1980–1990 Amazonian gold rush left an enormous liability that increasingly has been substituted by developing fish aquaculture. This work aimed at the identification of the mercury levels in the environment, associated with fish farms located in the North of Mato Grosso State, Southern Amazon. Sediment and soil samples were analyzed for total organic carbon and total mercury. Results indicate that the chemi...
