1. Predicting the potential distribution of aquatic herbaceous plants in oligotrophic Central Amazonian wetland ecosystems
ABSTRACT Aquatic herbaceous plants are especially suitable for mapping environmental variability in wetlands, as they respond quickly to environmental gradients and are good indicators of habitat preference. We describe the composition of herbaceous species in two oligotrophic wetland ecosystems, floodplains along black-water rivers (igapó) and wetlands upo

2. Assessment of Trace Element Contents in Soils and Water from Cerrado Wetlands, Triângulo Mineiro Region
ABSTRACT In the Brazilian Cerrado biome, there are wetlands locally known as “Veredas”, which are swampy plains between hills and rivers. Since the 1970’s, the Cerrado biome has been gradually converted to livestock, crop, or forestry production. Until now, very few studies were conducted to evaluate the baseline contents of trace elements in Cerrado w

3. Characteristics of Soils in Highland Wetlands as a Subsidy to Identifying and Setting their Limits
ABSTRACT Palustrine areas and wetlands in particular are fragile ecosystems, with high biodiversity and high ecological productivity, and they provide benefits to society. The aim of this study was to describe and classify the main soils occurring in the wetlands of the Southern Plateau of Santa Catarina, and propose criteria for identification of hydromorph

4. Germination and sporophytic development of Regnellidium diphyllum Lindm. (Marsileaceae) in the presence of copper
Regnellidium diphyllum Lindm. is a heterosporous fern growing in wetlands and humid soils that are being converted to agricultural activities. Many products that are used in agriculture contain copper, resulting in surface and groundwater contamination. Germination and initial development tests were performed using Meyer's solution containing copper sulphate

5. DinÃmica de fÃsforo em manguezais impactados por Ãguas residuÃrias no Estado do CearÃ. / Dynamics of phosphorus in mangroves impacted by the state of CearÃ.
Recent studies demonstrated the efficacy of mangrove retaining nutrients and, in particular, the ability of the mineral component of the buffer in its high soil phosphorus levels. In general, the mangroves have been considered as important sinks of nutrients due to its high capacity purification of effluents. However, depending on the geochemical conditions

6. Relações pedologia-geomorfologia-sedimentologia no Pantanal Norte / Relationships pedology-geomorphology-sedimentology in the Pantanal North
As relações entre os solos, material de origem e feições geomórficas são importantes para a compreensão da distribuição dos solos na paisagem e o entendimento de sua variabilidade espacial, sobretudo em ambientes úmidos (wetlands) de natureza sedimentar complexa. Procurou-se descrever e caracterizar os ambientes deposicionais de uma área de estudo

7. Atributos químicos e textura do solo em veredas conservadas e antropizadas no bioma Cerrado / Chemical attributes and texture of the soil in conserved and altered wetlands (veredas) in Cerrado biome
Este trabalho objetivou estudar os solos de áreas úmidas (veredas) situadas em ambientes conservados e antropizados (em áreas agrícolas e de pecuária), por meio da determinação de atributos químicos e textura do solo. O estudo foi realizado na região nuclear do bioma Cerrado, no estado de Goiás, em veredas situadas no município de Bela Vista de Go

8. Chemical attributes and texture of the soil in conserved and altered wetlands (veredas) in Cerrado biome / Atributos químicos e textura do solo em veredas conservadas e antropizadas no bioma Cerrado
The objective of this work was to study the soil of wetlands situated in conserved and altered environments (in agricultural and cattle areas), by determining the chemical attributes and texture of the soil. The study was carried through in the central region of Cerrado biome, in the state of Goiás, in wetlands situated in the City of Bela Vista de Goiás.

11. Ubiquity and Persistence of Escherichia coli in a Midwestern Coastal Stream†
Dunes Creek, a small Lake Michigan coastal stream that drains sandy aquifers and wetlands of Indiana Dunes, has chronically elevated Escherichia coli levels along the bathing beach near its outfall. This study sought to understand the sources of E. coli in Dunes Creek's central branch. A systematic survey of random and fixed sampling points of water and sedi
