Aquatic Plants and Animals

2003
The topic of this chapter is concerned with the greatest volume of the earth’s ecosystems. The separate sub-ecosystems and their organisms are introduced and exemplified. The fresh water systems are distinguished from the salt water systems and compared with respect to the affiliated organisms.

Phosphorus in primary aquatic plants

Water Research, 1973
Abstract As with other organisms, phosphorus is an essential element for aquatic plants. It is a component of molecules such as the nucleic acids and adenosine triphosphate (ATP) involved in the vital processes of enzyme synthesis and energy transfer and its compounds play a basic role in the mechanisms of photosynthesis by which these plants act as ...

Macrophytes : ecology of aquatic plants.

2009
Aquatic plants contribute to maintaining key functions and related biodiversity in freshwater ecosystems, and to provide the needs of human societies. The way the ecological niches of macrophytes are determined by abiotic filters and biotic ones is considered.

Some effects of polyphenols on aquatic plants: I. Toxicity of phenols in aquatic plants

Bulletin of Environmental Contamination and Toxicology, 1981
Physiological parameters such as cytoplasmic streaming and motility are used to analyze the effects of chemically different phenolic compounds. Test organisms included: Cyclotella cryptica, Dunaliella salina, Chlamydomonas reinhardii strain 137, Lemna minor and Euglena graclis.

Aquatic plant inspired hierarchical artificial leaves for highly efficient photocatalysis

, 2013
The natural leaf provides a superior template for engineering the artificial leaf in order to perform light energy conversion. To adapt to the aquatic environments, the aquatic plant leaves usually are thin and soft with excellent mass transportation and

Aquatic Plants for Phytotechnology [PDF]

, 2007
Surface flow constructed wetlands are being designed for the treatment of municipal waste waters in developed nations. However, use of constructed wetlands is not gaining momentum in tropical nations due to water scarcity and high surface evapotranspitration.

Aquatic Plant Communities

2019
This report evaluates the expected responses of aquatic plants to elevated concentrations of atmospheric CO/sub 2/. We include aquatic plants with emergent foliage, as well as submersed macrophytes and microscopic algae and consider both freshwater and marine plants.

Short-term succession of aquatic plant species richness along ecosystem productivity and dispersal gradients in shallow lakes

, 2013
Questions The highest species richness is usually expected at an intermediate stage of development since the last major disturbance event, but some studies have shown that ecosystem productivity and dispersal may modify this pattern, suggesting the ...

Conservation of aquatic plants

1990
It has been emphasised in the previous chapter that many aquatic plants tend to become aggressive weeds and interfere with the utilisation of water bodies for agriculture, pisciculture, recreation, etc. Different strategies for the management of such noxious growth of the aquatic plants are primarily aimed at eliminating them or at least reducing their
