AQUATIC ECOSYSTEM UPGRADES WATER QUALITY: MULTI-FACTOR ANALYSIS
Ostroumov S. A.    www.scribd.com/doc/64830562/

3 papers on how organisms clean water:
I would like to make three points:
1.In these three papers (mentioned in the blog below), the author demonstrated how aquatic invertebrates may contribute to making water clean and clear:

2.In this paper (see the blog below), the same author discovered some new facts on how aquatic plants may contribute to making water clean and removing heavy metals from water:

ABSTRACT: On the basis of the previous publications, our new data and the existing scientific literature, we have formulated some fundamental principles that characterize the pivotal roles of the biodiversity of filter-feeders in ecosystems. Among those roles are: (1) the role of ecological repair of water quality, (2) the role of contributing to reliability and stability of the functioning of the ecosystem, (3) the role of contributing to creation of habitat heterogeneity, (4) the role of...

Is biodiversity instrumental for increasing stability of aquatic ecosystems? Yes!
The reason for this answer is as following. The role of biodiversity in benefiting stability of ecosystems is a matter of hot dispute. Not much was known on whether biodiversity is instrumental for increasing stability of aquatic ecosystems. A research project was done that is filling the gap in knowledge on this controversial issue. A paper was published that provides a fresh analysis and new vision of how biodiversity helps towards better stability of aquatic habitats, i.e. water quality. The author made experiments with filter-feeders (bivalves) and as result of an analysis of his experimental data, he formulated the following suggestion: to maintain water...
