| Popis: | Phytoplankton community responses were used in a heavy metals (HM) marine pollution monitoring biological system. A multifactorial analysis was used in in situ experiments in the White Sea to study HM toxicity to a planktonik algae population in their copresence. It was ascertained that algae with a high rate of increase in population size, producing metabolites, restricting development of phytoplankton community associates, gain advantages in isolation conditions. The algae responded differently to addition of individual metals and their combinations in the environment. Change in the number of dominants resulted in disturbance of the phytoplankton community structure. It has been shown that there are cardinal points in phytoplankton development, determining the growth of individual algae populations and planktonic community on the whole, against a background of competition for biogenic elements and space in conditions of TM environment pollution. |
