Organic Control of Dioctahedral and Trioctahedral Clay Formation in an Alkaline Soil System in the Pantanal Wetland of Nhecolândia, Brazil
Recent studies have focused on the formation of authigenic clays in an alkaline soil system surrounding lakes of the Nhecolândia region, Pantanal wetland. The presence of trioctahedral Mg-smectites (stevensite and saponite types), which requires low Al and Fe contents in the soil solution for its formation, contrasts with the neoformation of dioctahedral Fe-mica (glauconite, and Fe-illite), whi...
متن کاملDistribution, composition and seasonality of aquatic birds in the Nhecolândia sub-region of South Pantanal, Brazil.
Despite remarkable significance of Pantanal for the conservation of aquatic birds, the status of their populations, the spatiotemporal patterns of distribution and habitat use and structure of communities are little known. Thus, we studied three aquatic environments (Negro river, bays and salines) from 2007 to 2009 in the Nhecolândia Pantanal to verify the distribution and composition of aquati...

Detection of Saline and Non-saline Lakes on the Pantanal of Nhecolândia (brazil) Using Object-based Image Analysis
The Pantanal (Brazil) is one of the world’s largest tropical wetlands. A natural phenomenon that encourages more detailed scientific studies on this region is the genesis and behavior of innumerable small lakes and ponds with open-water surfaces on the Nhecolândia region at the Taquarí alluvial fan. In this paper, we suggest a new approach to detect and differentiate lakes among saline and nons...
