Alan Newman voted up your answer to:
Does the current environmental law give enough attention and appreciation to full range of useful roles of entire aquatic biota in water ecosystems?





This is a part of the answer (by Dr. Sergei A. Ostroumov) that was voted up:

  • I am a bit critical about The Trent Biotic Index. This index ignores -or underestimates - some groups of organisms of huge importance in aquatic ecosystem - e.g.. bivalve molluscs who filter and purify water...
    Again, thanks,  and your answer is voted up. Would you please see below- some info on a useful review paper on filter-feeders.
    Best regards.

    Some aspects of water filtering activity of filter-feeders.

    ABSTRACT. A review with fresh ideas: multi-faceted role of filter-feeders in ecosystems.
    https://www.researchgate.net/publication/226902807_Some_aspects_of_water_filtering_activity_of_filter-feeders ;
    In the article, some new concepts were introduced, namely: ecological taxation in ecosystems; ecological repair.
    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 aquatic ecosystems. Among those roles are:
    (1) the role of ecological repair (improvement) 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 aquatic habitat heterogeneity,
    (4) the role of contributing to acceleration
    of migration of chemical elements.
    It is an important feature of the biomachinery of filter-feeders that it removes from water
    various particles of a very broad range of sizes. Another important principle is that the amount of the organic matter filtered out of water is larger than the amount assimilated so that a significant part of the removed material serves no useful function to the organism of the filter-feeder, but serves a beneficial function to some other species and to the ecosystem as a whole.
    The new experiments by the author additionally demonstrated a vulnerability of the filtration activity of filter feeders (e.g., bivalves and rotifers) to some xenobiotics (synthetic surfactant tetradecyltrymethylammonium bromide, heavy metals and some others). The inhibition
    of the filtration activity of filter-feeders may lead to the situation previously described as that of an ecological hazard of the second type.
