title: Genetic flows in a structured one-dimensional population: simulation and real data on Baikalian polychaetes M. godlewskii.
abstract: In this work, we apply population dynamic approach enhanced with simulation of the fate of neutrally evolving "DNA sequences" included into each individual in the computer experiment to the case of the Baikalian endemic polychaetes Manavunkia. These animals inhabit a narrow littoral zone around whole the lake perimeter and are of very limited mobility. Accordingly, the general model was modified by addition of a "geographic barrier" of different isolating power and length of existence. Using this model, we simulated the process of genetic differentiation of groups in this organism taking into account isolation by distance and geographical barriers. Wright's F(st) test was used in order to estimate of genetic flow. Relevant sample sizes were estimated, which would produce most important population parameters of the precision required to describe micro-evolutionary processes in Manayunkia.
