Conference publicationsAbstractsXVI conferenceInfluence of the invasion of intermediate predator on ecosystem dynamics of Naroch group of lakes of the republic of BelarusInstitute of Theoretical & Experimental Biophysics, Pushchino State University, Pushchino, Moscow Region, 142290 Russia Tel.: +7(4967)739238. Fax: +7(4967)330553 1 pp. (accepted)In current paper conceptual model of Naroch group of lakes of the republic of Belarus water ecosystem is suggested. This model includes trophic interactions between the fish (predator) and rotifer (prey) as well as age structure of fish population. Furthermore, takes into consideration the biomass exchange between the particular water bodies. The influence of the invasion (opossum shrimps) on the character of ecosystems behavior is studied. Detailed phase-parametric analysis in model parameter space has been carried out.
