• Abstract

  The wetlands have a fundamental role in the control of factors that can affect or be affected by the climatic and environment changes. The project will be developed in Nhecolândia (South Mato Grosso State), a region characterized by a system of lakes, with water composition varying from fresh to hyper saline. It is concerned to a multi and interdisciplinary research whose scientific chall…

  Climatic changes and environmental impacts in wetlands of Pantanal region (Brazil): quantification, control factors and long term temporal modeling, AP.PFPMCG.TEM

• Abstract

  The Amazonian podzols may store larger amounts of carbon (C) particularly in their deep Bh horizons. Similar high C storage is likely to exist in similar climate/soil areas, mainly in Africa. Such C stocks raise the problem of their stability in response to changes in land use or climate. Any significant changes in vegetation cover would significantly alter the soil water dynamics, Which …

  Modelling the dynamics of equatorial forest soil deep carbon in changing environments - C-PROFOR, AP.TEM

• Abstract

  The quantification of stocked C in natural environment and the evaluation of its sensibility towards the climatic changes or land use represent a research domain in great expansion. The Amazon Region presents a large area of Spodosols (ES), characterized by the presence of thick sandy horizons, overlaying more clayey horizons. The organic matter (OM) formed on the surface is transferred, …

• Abstract

  The importance of organic matter influencing the behavior of chemical elements in soil and sediments is highlighted in the scientific literature, especially in relation to the elements iron and aluminum. The focus of the present project is to verify the relationships between the main elements (Si, Mg, Ca, Na, K, Al and Fe) observed in the soils around lagoons with saline-alkaline waters a…

  INFLUENCE OF ORGANIC MATTER ON THE DYNAMICS OF CHEMICAL ELEMENTS IN SOIL AND SEDIMENTS IN THE NHECOLAND REGION (MS), BP.IC

• Abstract

  The Nhecolândia region is characterized by the presence of a complex fluvio-lake system whose lagoons have different characteristics. Lagoons with crystalline and black waters do not have a hypersaline character like the green water lagoons. The hypersaline character was explained by Martins (2012) due to the rapid transfer of water stored in the soil to the lagoons. Soil pH can influence…

  Influence of pH on the neoformation of soil secondary minerals surroundings of a crystalline pond in the region of Nhecolândia (MS), BP.IC

• Abstract

  The Pantanal continuous sedimentary plain, specifically in the Nhecolândia subregion, is characterized as an area of approximately 26,000 km2 and about 15,000 lagoons. The waters of this important lake system range from fresh to saline, due to the peculiarities associated with the subregion. Through the project titled "Climate change and environmental impacts in wetlands of the Pantanal (…

  Geochemical and mineralogical control of the soil-lagoon system functioning of Nhecolândia, Pantanal, Mato Grosso do Sul, BP.DR

(Only some records are available in English at this moment)

• Abstract

  This project aims to evaluate speciation in solid phases and the availability of iron and aluminum in clay neoformations, in the southern region of Nhecolândia, Pantanal. Soils surrounding lakes with saline-alkaline waters of different colors, present significant contrasts between physical-chemical parameters and different mineralogical contributions. Thus, soils and lakes with different …
