Evolution of Species and Ecosystems: Theoretical Analysis and Computer-Assisted Modeling

Numerical assimilation or “fitting model to data” is a set of powerful computational methods widely using in meteorology and oceanography. The main goal of this computational procedures is to produce better correspondence between observations and simulations preserving physical assumption on processes under consideration. The basic ideas of these methods are originated to G.I.Marchuk, Kalman and others. During last years the number of attempts were made to apply methods of numerical assimilation in the area of ecological modeling. Several studies have been realized, mainly in the water ecosystems modelling, including some papers of the author. However, applicability of numerical procedures developed for solution of hydrophysical problems, to the description of biological systems is still under the question. Between general problems are, presence of many living components in the model and there is no regular observations for many of them; simple physical measurements of biomass give no information on species composition. We present a review of different attempts to data assimilation in the models of water ecosystems and state a problems arising in calculations, data analysis and results interpretation.
