1. From forests to cattail: how does the riparian zone influence stream fish?
O presente estudo verificou se a composição taxonômica e funcional de peixes de riachos varia ao longo de três condições de preservação da zona ripária: preservada (PRE), preservação intermediária (INT) e degradada (DEG). Cinco riachos de cada grupo foram selecionados e amostras foram obtidas em cada riacho em três ocasiões em períodos secos d

2. Capacidade desnitrificante de sistemas alagados construídos operados em bateladas sequenciais / Denitrification ability of sequencing batch constructed wetlands
Investigações relacionadas ao uso de sistemas alagados construídos (SACs), para tratamento secundário e terciário, têm sido conduzidas em centros de pesquisas brasileiros na última década. No que diz respeito ao tratamento terciário, pode-se considerar que a remoção de nitrogênio se dá por uma gama ampla de mecanismos físicos, químicos e biol�

3. Tratamento de esgoto sanitário em sistemas alagados construídos utilizando Typha angustifolia e Phragmites australis / Sanitary sewer treatment in constructed wetlands system using Typha angustifolia and Phragmites australis
This study aimed to assess the efficiency of two vegetal species in the treatment of the sanitary sewer, in constructed wetlands system. Specifically, it aimed to evaluate the efficiency of the species Typha angustifolia (narrow-leaf cattail) and Phragmites australis (common reed), in their possible combinations, in the treatment of the sanitary sewer, in a

4. Fish assemblages in stream stretches occupied by cattail (Typhaceae, Angiospermae) stands in Southeast Brazil
Macrófitas são um importante componente de ecossistemas aquáticos lóticos e lênticos. Como consequências da degradação ambiental, espécies de taboas (gênero Typha) podem se tornar dominantes em riachos. O objetivo do presente estudo foi investigar a estrutura e alimentação de uma comunidade de peixes em trechos de riachos com influência de Typha

5. Evaluation of ametryn fate and transport in constructed wetlands systems / Avaliação da remoção e transporte do herbicida ametrina em sistemas alagados construídos
O uso de agroquímicos pode causar uma grande variedade de impactos negativos em ambientes aquáticos. Em áreas de exploração agrícola, onde são usados tais produtos, há uma demanda por sistemas de bioremediação que conjuguem baixos custos e simplicidade operacional. Na presente tese são apresentados os resultados da pesquisa que consistiu em se inv

6. Mineralization of Surfactants by Microbiota of Aquatic Plants
The biodegradation of linear alkylbenzene sulfonate (LAS) and linear alcohol ethoxylate (LAE) by the microbiota associated with duckweed (Lemna minor) and the roots of cattail (Typha latifolia) was investigated. Plants were obtained from a pristine pond and a pond receiving wastewater from a rural laundromat. Cattail roots and duckweed plants were incubated

7. Microbial Degradation of Lignocellulose: the Lignin Component
A new procedure was developed for the study of lignin biodegradation by pure or mixed cultures of microorganisms. Natural lignocelluloses were prepared containing 14C in primarily their lignin components by feeding plants l-[U-14C]phenylalanine through their cut stems. Lignin degradation was observed in numerous soils by monitoring evolution of 14CO2 from [1

8. Photosynthesis and Photorespiration in Typha latifolia1
Photosynthetic rates of Typha latifolia, the broad-leaved cattail, are the equivalent of rates reported in tropical grasses and other plants which assimilate carbon by the phosphopyruvate carboxylase reaction, but photosynthesis in T. latifolia proceeds by a typical Calvin cycle. Glycolate oxidase, the photorespiratory enzyme, is present in high concentratio

9. Altered Phase Behavior in Membranes of Aging Dry Pollen May Cause Imbibitional Leakage.
Aging of dry pollen has been shown to coincide with increases of free fatty acids and lysophospholipids. These compounds reduce the integrity of hydrated liposomes made from isolated pollen phospholipids but do not lead to their total destruction. However, a massive, instantaneous leakage occurs upon imbibition of dry cattail pollen (Typha latifolia) that ha

10. Aerenchyma Carbon Dioxide Can Be Assimilated in Typha Iatifolia L. Leaves.
Leaf structural characteristics and gas-exchange measurements were used to determine whether photosynthetic tissue of Typha Iatifolia L. (cattail) utilized CO2 from the aerenchyma gas spaces, part of an internal pathway for gas transport in this wetland species. The partial pressure of CO2 (pCO2) in these aerenchyma gas spaces can be more than 10 times atmos

11. Associations of methanotrophs with the roots and rhizomes of aquatic vegetation.
Results of an in vitro assay revealed that root-associated methane consumption was a common attribute of diverse emergent wetland macrophytes from a variety of habitats. Maximum potential uptake rates (Vmaxp) varied between about 1 and 10 micromol g (dry weight)-1 h-1, with no obvious correlation between rate and gross morphological characteristics of the pl

12. Influence of Water Content and Temperature on Molecular Mobility and Intracellular Glasses in Seeds and Pollen1
Although the occurrence of intracellular glasses in seeds and pollen has been established, physical properties such as rotational correlation times and viscosity have not been studied extensively. Using electron paramagnetic resonance spectroscopy, we examined changes in the molecular mobility of the hydrophilic nitroxide spin probe 3-carboxy-proxyl dur
