Histosols in an Upper Montane Environment in the Itatiaia Plateau

Paula Fernanda Chaves Soares, Lúcia Helena Cunha dos Anjos, Marcos Gervasio Pereira, Luiz Carlos Ruiz Pessenda


ABSTRACT: Highland environments favor accumulation and preservation of soil organic matter (SOM) due to low temperatures, leading to the formation of Histosols. The Itatiaia National Park (INP), Rio de Janeiro, Brazil, offers conditions for preservation of SOM deposited over time, which has led to the formation of these soils. The objective of this study was to characterize Histosols in this environment, with the premise that it may provide evidence of changes in vegetation. Organossolos (Histosols) were sampled, characterized, described, and […]

Characterization and classification of soils in the Taquari river basin – Pantanal region, state of Mato Grosso do Sul, Brazil

Jolimar Antonio Schiavo, Antonino Hypólito Dias Neto, Marcos Gervasio Pereira, Jean Sérgio Rosset, Mateus Luiz Secretti, Luiz Carlos Ruiz Pessenda


Among the soils in the Mato Grosso do Sul, stand out in the Pantanal biome, the Spodosols. Despite being recorded in considerable extensions, few studies aiming to characterize and classify these soils were performed. The purpose of this study was to characterize and classify soils in three areas of two physiographic types in the Taquari river basin: bay and flooded fields. Two trenches were opened in the bay area (P1 and P2) and two in the flooded field (P3 and […]

Pedological and isotopic relations of a highland tropical peatland, Mountain Range of the Espinhaço Meridional (Brazil)

Ingrid Horák, Pablo Vidal-Torrado, Alexandre Christófaro Silva, Luiz Carlos Ruiz Pessenda


The evolution of organic matter sources in soil is related to climate and vegetation dynamics in the past recorded in paleoenvironmental Quaternary deposits such as peatlands. For this reason, a Histosol of the mineralotrophic peatland from the Pau-de-Fruta Special Protection Area – SPA, Espinhaço Meridional, State of Minas Gerais, was described and characterized to evidence the soil constituent materials and properties as related to changes in environmental conditions, supported by the isotopic and elementary characterization of soil C and N […]

Quaternary evolution, particle distribution in soils and sedimentary environment in mangroves in São Paulo State, Brazil

Valdomiro Severino de Souza-Júnior, Pablo Vidal-Torrado, Moysés Gonzalez Tessler, Luiz Carlos Ruiz Pessenda, Tiago Osório Ferreira, Xose Luiz Otero, [...]


Particle distribution in soil or sediments of coastal plains contributes to the understanding of the sedimentation processes in estuaries. It is an important attribute for applications in studies of palaeoenvironmental reconstruction, geochemical cycles and environmental pollution such as heavy metal and oil spill contamination, which are relatively common in these sites due to human impact. With the objective of characterizing the sedimentary environments according to the particle size and the process of quaternary evolution, 14 mangroves along the São Paulo […]
