- Аннотация: An optimized mesocosm setup was designed for experimental investigation of the internal mechanisms (trophic relations and interactions between species and trophic levels) that drive plankton dynamics under the constant external conditions. This setup was used in two consecutive one year-long mesocosm experiments, each carried out in four replicates. In both experiments, all replicates had similar initial conditions; moreover, the abiotic parameters (temperature, irradiance and water movement) were kept stable throughout the experiment and were similar in all replicates. The experimental setup, including techniques for water mixing and control of temperature and light conditions, sampling procedures and methods of data analyses are described in detail. Some results for the starting period of the first experiment are shown (e.g., dynamics of total nutrients and seston properties). In one replicate, deviation of the measured parameters from those in the other three replicates was revealed which was not attributed to the external drivers. The overall results of the experiments demonstrated high degree of long-term stability of external drivers for plankton dynamics (light, temperature and salinity) as well as acceptable similarity of these parameters in the mesocosm replicates. The applicability of this approach and experimental design for unraveling the internal mechanisms of plankton dynamics is discussed.
