Sergei Ostroumov–Mar 8, 2010
A challenge in ecology is the multitude of factors that influence all ecological processes. It is difficult to find a balance when we analyze them. A new theory was created that unified and balanced many physical, chemical and biological factors that work together toward improving water quality.(View details)Sergei Ostroumov–Mar 7, 2010
To implement environmental law, it is necessary to have adequate, clear and precise interpretation (definitions) of the basic ecological terms, including the definition of ecosystem. The standard definition is vague. A new definition was published.(View details)New plant species as a potent tool to clean water and to remove heavy metals
Sergei Ostroumov–Mar 4, 2010
This is the first time the phytoremediation potential of a new wide-spread species of plants was discovered. The plant removed the toxic metals cadmium, lead, copper, zinc (Cd, Pb, Cu, Zn) from water with great efficiency. As a result, water quality improved dramatically with prospect of new technology(View details)The Threat of Shampoo to the Biosphere
Sergei Ostroumov–Jan 30, 2010
This paper indicated that components of shampoo pose a dramatic danger and hazard to intimate ecosystem services that are a keystone for the security and stability of the biosphere. Foam from shampoo was found to be of much more environmental hazard than previously thought. (View details)Sergei Ostroumov–Jan 13, 2010
Major functions of ecosystem are traditionally being described in a dogmatic, stagnant, and antiquated way. A paper was published with a new conceptual addition to key functions of aquatic ecosystem: the latter is seen as a kind of a grand autonomous bioreactor governed by a diverse genetic pool(View details)Stopping Pollution: Eutrophication and Algal Blooms
Sergei Ostroumov–Jan 8, 2010
A new approach to prevent pollution, eutrophication, and algal blooms was identified and analyzed in this paper . The approach is based on efficient use of the natural mechanisms of self-regulation of ecosystem.(View details)Underwater Secrets of Global Change
Sergei Ostroumov–Jan 6, 2010
What is the global change? Usually it is seen as something that is relevant to the atmosphere and weather. It is true that air is involved, but not only the air alone; what happens in water is less visible. This paper unveils this hidden side of ecosystems, and discusses both hopes and hazards.(View details)Vulnerability of Major Plankton Groups: Rotifers
Sergei Ostroumov–Jan 5, 2010
Welfare of the biosphere depends on filter-feeders that contribute to making water clean. Important new facts on the new type of hazard of man-made damage to the beneficial function of rotifers, which are plankton filter-feeders, were discovered. (View details)Three New Key Hazards to the Functioning of the Biosphere
Sergei Ostroumov–Jan 2, 2010
A paper in which the author discovered man-made hazards to 3 aspects of functioning of the biosphere and ecosystems: (1) formation of water quality; (2) bio-geochemical flows of C, N, P and other constituents of biomass; (3) formation of deposits of organic matter as bottom sediments.(View details)Inhibitory Analysis: A new method for analyzing interactions between organisms in ecosystems
Sergei Ostroumov–Dec 12, 2009
The author proposed a new approach to analyze a key ecological issue: the interactions between organisms in ecosystems. The new methodology proposed is inhibitory analysis. The author applied this approach to analyze trophic chains: the top–down control of plankton by benthic filter-feeders.(View details)Sergei Ostroumov–Dec 6, 2009
The common vision is that the main eco-hazard is effects on organisms that are the final target. This is an incorrect view. The paper discovers hazards from summation of mild effects on adjacent trophic levels. Example of effects of pollutants on filter-feeders, algae and water quality is given.(View details)Criteria of ecological hazards due to anthropogenic effects on the biota: Searching for a system
Sergei Ostroumov–Dec 1, 2009
The system of criteria for evaluation of eco-hazards of chemicals in W.Europe and N.America is outdated and does not guarantee environmental safety. The author gave a conceptual framework for an ecologically more sound system of criteria, with an example of its application to a real situation. (View details)Sergei Ostroumov–Dec 2, 2009
The author formulated a new basic concept of the complex of organisms of aquatic ecosystem. According to the concept, the biota is a central, labile and vulnerable (to pollutants) part of the ecological mechanism of water self-purification and upgrade of water quality.(View details)Sergei Ostroumov–Nov 29, 2009
An aquatic ecosystem: a large-scale diversified bioreactor with a water self-purification function. The author developed an innovative concept of ecosystem as a multifunctional bioreactor, one of its functions is upgrading water quality. (View details)A new type of effect of potentially hazardous substances
Sergei Ostroumov–Nov 21, 2009
A new type of effect of potentially hazardous substances: un-couplers of pelagial–benthal coupling. Discovery of a new type of negative impact of pollutants on the biosphere, as the outcome of inhibition of water filtration by filter-feeders.(View details)Join our network
