Review: First paper to link biogeochemistry,ecology of freshwater mollusks   (2014-05-23)  Evaluation: Review by Professor_S.K. Unique, top article. Linking ecology and biogeochemistry. First paper to report the new facts: (1) first quantitative data  on fluxes of chemical elements with the pellets of mollusks, per 1 m2 of bottom of freshwater ecosystems; (2) discovery of the fact that chemical pollutants can inhibit these fluxes. Prior to this publication, no quantitative data  - data on fluxes of chemical elements with the pellets of mollusks, per 1 m2 of bottom of freshwater ecosystems - existed in scientific literature. Another unique result in this paper: the first discovery of the fact that chemical pollutants (exemplified by synthetic surfactants, and a detergent) inhibit these fluxes. This an absolutely pioneering, innovative article. The paper reports the first measurements of some key chemical elements (C, N, P, Si, and Al) in the pellets of aquatic mollusks (freshwater mussels). The first measurements of the biogeochemical fluxes of those elements with the pellets, calculated per unit of area of freshwater ecosystem (per 1 m2). A measurement of the previously unquantified geochemical fluxes of chemical elements in the biosphere: the vertical (downward) fluxes of the chemical elements toward the bottom of freshwater ecosystems, via pellets of bivalves (freshwater mussels, Unio sp. and other species).

The paper discovered the role of mollusks as  key biomachines that drive massive flows of chemical elements including C, N, P, Si, Al in the biosphere, and hazards from pollutants as inhibitors. New data on coupling of geochemical and ecological processes. The role of freshwater mollusks (the great pond snail) Lymnaea stagnalis   in the flows of chemical elements in the biosphere was studied by detecting the elemental composition and amount of pellets produced by the mollusks.  For the first time, the following was quantitatively studied: the elemental composition (C, N, P, Si, Al) of the pellets formed by mollusks Lymnaea stagnalis feeding on the leaves of aquatic higher plants Nuphar lutea and Taraxacum officinale; the amount (wet weight, dry weight) of the pellets formed by L. stagnalis feeding on the leaves of N. lutea and T. officinale; the transfer of  the organic matter and chemical elements (C, N, P, Si, Al)  with pellets of freshwater bivalves (unionids Unio sp., etc.) per unit biomass of mollusks and per unit area of the ecosystem of the river; the transfer of matter and chemical elements (C, N, P, Si, Al) with the pellets of L. stagnalis per unit biomass of mollusks and per unit area of the ecosystem of the pond. The chemical pollutants, synthetic surfactants ТDТМА 2 mg/l, SDS 1-2 mg/l, detergent Tide-Lemon 75 mg/l inhibited the trophic activity of L. stagnalis.   Percents of food assimilability of taxons of invertebrates, from Rotatoria (48-80) to Diptera (1-31)].

The paper is recommended to all involved in freshwater ecology, limnology, environmental toxicology, aquatic toxicology, ecotoxicology, biogeochemistry.

Unio is a genus of medium-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. Unio is the type genus of the family Unionidae. About this family: The range of distribution for this family is world-wide. It is at its most diverse in North America, with about 297 recognised taxa, but China and Southeast Asia also support very diverse faunas. Freshwater mussels occupy a wide range of habitats, but most often occupy lotic waters, i.e. flowing water such as rivers, streams and creeks. Source of the data for this comment: Wikipedia. ** Explanation of methodology (some details on the choice of the biological species and chemicals to study). Why the great pond snail and freshwater mussels were studied in this reseach project: they are among the most common benthic species of invertebrates in water habitats of Eurasia. Their biomass is one of the biggest, or just the biggest, among aquatic invertebrates in Eurasia and other parts of the world. Why the plant species, Nuphar lutea (Yellow Water-lily) , was used in this research project: it is one of the most common aquatic plant species in the freshwater habitats of Eurasia. Why the plant species, Taraxacum officinale, was used in this research project: it is a common laboratory practice to feed the great pond snail with leaves of this higher plant. Why the synthetic surfactants ТDТМА  (tetradecyltrimethylammonium bromide) and SDS (sodium dodecyl sulfate) were used: they are representatives of the two major classes of synthetic surfactants, namely, cationic surfactants, and anionic surfactants. These two chemicals were studied in many other publications of Dr. Sergei Ostroumov, so that lots of data to compare toxic effects of these chemicals on organisms are available.  A detailed explanation of methodology was also published in the book Biological Effects of Surfactants (Ostroumov, 2005,  https://www.researchgate.net/publication/200637626) ** Explanation of terminology: pellets are the particles of  the undigested  organic matter (mainly biomass of undigested food) that the aquatic mollusks (snails and freshwater mussels) excrete so that these mollusks function as engines that drive the transfer of a significant amount of the organic matter through aqautic ecosystems. ** This review was published:  http://www.redlightgreen.com/profiles/Professor_S.K./reviews/2405248?reviewaction=fetchfull Was this review helpful to you?
