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 abolutely 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 elements toward the bottom of freshwater ecosystems, via pellets of bivalves (freshwater mussels, Unio sp. and other species).

Pellets of some mollusks in the biogeochemical flows of C, N, P, Si, and Al. - Doklady Biological Sciences, 2001. Vol. 379, P. 378-381. (Translated from: DAN 2001. Vol. 379. No. 3. P. 426-429). ISSN 0012-4966. Until now the role of mollusks as links among ecological and geochemical processes was underestimated. 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 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 pellets formed by mollusks Lymnaea stagnalis feeding on the leaves of higher plants Nuphar lutea and Taraxacum officinale; the amount (wet weight, dry weight) of pellets formed by L. stagnalis feeding on the leaves of N. lutea and T. officinale; the transfer of 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 pellets of L. stagnalis per unit biomass of mollusks and per unit area of the ecosystem of the pond. 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.
