Floating aquatic macrophytes for the treatment of aquaculture effluents
Environmental Science and Pollution Research, 2020Aquaculture is an activity with economic and social importance since it generates food, employment, and income. However, like other human activities, it negatively impacts the environment, in this respect mainly due to the production of effluents rich in sedimentable solids, organic matter, phosphorus, and nitrogen.

A macrophyte submodel for aquatic ecosystems
Aquatic Botany, 1989Abstract A macrophyte submodel has been incorporated and tested in CE-QUAL-R1, a one-dimensional, vertically averaged model of reservoir water quality. A quasi two-dimensional scheme was necessary to represent the spatial relationship of macrophytes in reservoirs adequately.

Amino Acids in Aquatic Macrophytes
Zeitschrift für Pflanzenphysiologie, 1977Summary Ranunuculus aquatilis, Ranunclus fluitans, Elodea canadensis, Potamogeton pectinatus, Potamogeton natans and Zannichellia palustris were collected from homogenous populations in their natural environment. 1. Fewer amino acid components were detected than usually found in plants with the described automatic method. 2. The absolute

The sorptive capacity of an aquatic macrophyte for the pesticide aminocarb
Journal of Environmental Science and Health, Part B, 1985Ceratophyllum demersum exposed to a constant 1 microgram/ml aminocarb exhibited a large capacity for the sorption of the pesticide, up to 400 micrograms/g fresh weight in the dark and 1000 micrograms/g fresh weight in the light. Smaller, actively growing sprigs sorbed 5 times more pesticide per gm fresh weight than larger, older sprigs, although total ...

Scaling of photosynthetic production of aquatic macrophytes ? a review
Oikos, 2007Most studies on photosynthetic production of aquatic macrophytes have been made on detached leaves and algal thalli. This may have given the false impression that production is often saturated by light and that inorganic carbon and nutrients are more important limiting factors. However, studies on the more relevant ecological scale

Sorption and photodegradation of chlorpyrifos on riparian and aquatic macrophytes
Journal of Environmental Science and Health, Part B, 2008Surface water bodies may become contaminated via spray drift following pesticide application. In this investigation, the photodegradation and sorption of chlorpyrifos was studied in four riparian macrophytes representative of Mediterranean flora (Phragmites australis, Iris pseudacorus, Equisetum pratense and Typha latifolia). The results of experiments

Aquatic macrophytes and Eichhornia crassipes
1982Munro (1966) defined the shoreline habitats of Lake McIlwaine in terms of the presence or absence of aquatic macrophytes, and the major species of macrophyte where the plants were present. Relatively few areas of the lake shore were free of macrophytes (Fig.

Surface-floating aquatic macrophytes
1985Aquatic plants that float on the water surface occupy a distinctive habitat that requires particular adaptation. Furthermore, since they are not affected by water depth, they are not limited to a particular zone in the hydrosere but may occur wherever there is sufficient free water.
