Use of the Simulation Model for the Analysis of the Impact of Parasites on the Dynamics of Abundance, Reproduction, and the Transition to Diapause in the Mass Rotifers Brachionus calyciflorus Pallas of the Volga Delta
Rotifers are one of the most important groups of zooplankton, and they play an important role in aquatic ecosystems as initial energy converters of primary and bacterial products. In the course of monitoring studies of the state of ecosystems, many questions arise, the solution of which is necessary for correct interpretation of the data obtained. When considering the dynamics of the abundance of zooplankton and its constituent groups, the main focus is on the state of temperature and oxygen regimes, feed conditions, competitive relationships, and predator consumption, and too little attention is paid to the effects of parasitic organisms on plankton. The question of rotifer infection and the possible influence of this factor on their population dynamics is still poorly studied. Simulating of these processes with the help of mathematical model is described.
