--Pellet excretion by the gastropods Lymnaea stagnalis feeding on the phytomass of macrophytes (such as Nuphar lutea) was as high as 4–7 mg absolute dry weight per 1 gram wet weight of the mollusks per 72 h. Pellet sedimentation contribute to vertical transfer of chemical elements in the ecosystem. The pellet composition varies depending on the species of the plants eaten by the mollusks. When L. stagnalis feed on N. lutea, the pellets contain, in addition to organic...

Ostroumov S. A. The concept of aquatic biota as a labile and vulnerable component

Abstract. A new fundamental concept of the role of biota in the functioning of aquatic ecosystems is proposed. According to that concept, the complex of aquatic organisms (aquatic biota) is a central, labile and potentially vulnerable component of the water self-purification system in aquatic ecosystems. This fundamental concept leads to substantial changes in the hierarchy of priorities for protection of biodiversity and environment. According to the concept suggested in this work, the maximum allowable...

The author discovered and characterized a new type of ecological hazard of chemical pollution of water, which involves inhibition of important processes of ecological remediation of ecosystems (water filtration by aquatic bivalves). Experiments were performed using mollusks (oysters), Crassostrea gigas Thunberg, and a cell suspension of Saccharomyces cerevisiae. The cell suspension was a model of suspended matter in aquatic ecosystem. Laundry detergent Lanza-Automat inhibited water filtration by oysters...

Ostroumov S. A. Biodiversity Protection and Quality of Water:
The Role of Feedbacks in Ecosystems //Doklady Biological Sciences, Vol. 382, 2002, pp. 18–21.
A new fundamental principle was proved in the paper: to maintain the water quality, it is
necessary to protect the functionally active biodiversity
of water ecosystems. In other words, protection of the
functionally active biodiversity of aquatic organisms in
a water body is a method (and an indispensable one) of
maintenance of water quality in this ecosystem. Also, the author reports new experimental data on how detergents inhibited filtration activity of marine bivalves, mussels Mytilus galloprovincialis, and oysters Crassostrea gigas.
