    Фитопланктон и фитоперифитон в разновозрастных карьерных водоемах отработанных меловых месторождений (Беларусь) [Articol]

    The studies ofphytoplankton andphytoperiphyton were conducted on sixquarry reservoirs, whose age ranges fromless than 1 yearto 60 years. Communities in these waterbodies undergo different stages of ecological succession. It has been shown that the phytoplankton in the early stages of succession (<1 year after flooding ofquarry) is characterized by low values of density and biomass with absolute dominance in biomass of the large colonial algae Dinobryon divergens Jmhof (Chrysophyta). By the number of algae species in the plankton and periphyton of then ewly flooded reservoir (age less than 1 year) dominant were diatoms, while in other reservoirs green algae were dominating. The structure parameters of phytoplankton and phytoperiphyton in the quarry reservoir with the age about 20 years were similar to that in the long-lived (nearly 60 years) reservoirs. This fact gives the evidence of a relatively highspeed of the succession process in plankton and periphyton communities in such reservoirs.
