Abstract:
... Sedimentary deposits in both Colorado Basin and Salado Basin, two geological basins originated after the Atlantic rifting in the coastal area of Argentina, contain deep confined aquifers bearing thermal waters. Previous studies on the paleogroundwater of this region have been limited by the radiocarbon dating range. In this study ⁸¹Kr dating is applied to reveal groundwater ages up to 1.1 Ma, so f ...

Abstract:
... This work aimed to understand the drivers of landscape evolution and floodplain formation in a Precambrian Shield area of southeastern Amazonia. This area evolved during the Quaternary into a denudational system with strong structural control, which produced valley side slopes between the Araguaia Belt (AB) and the topmost Parnaíba basin and narrow floodplains in the lower Vermelho River. These fl ...

Abstract:
... An assessment of the intrinsic aquifer vulnerability of South America is presented. The outcomes represent the potential sensitivity of natural aquifers to leaching of dissolved compounds from the land surface. The study, developed at continental scale but retaining regionally a high resolution, is based on a critical application of the DRASTIC method. The biggest challenge in performing such a st ...

Abstract:
... Miconia is among the largest plant genera in the Neotropics and a taxonomically complex lineage. Indeed, molecular phylogenetic data shows that none of its traditionally accepted sections are monophyletic, preventing taxonomic advances within the genus. Miconia is the largest plant genus in the Brazilian Atlantic Forest, including three main lineages, the Leandra s.s. clade (ca. 215 spp.), the Mic ...

Such risks should be mitigated considering the bioavailable concentration of the element, since it implies immediate damage to the ecosystem. The objective of this study was to evaluate the potential of biochars in mitigating the enviro ...
