Spatial and Temporal Self-Organization of Bacterial Population

Abstract

The peculiarities of self-organization of a bacterial population are analyzed. Comparison of the dynamic characteristics of a bacterial population received experimentally by biological and optical methods is made. It is shown that the observable dynamic properties of population are connected with its spatial self-organization. Such behavior of moving microorganisms is a consequence of the search for optimum conditions of viability retention.

Directed Movement of Predators and the Emergence of Density-Dependence in Predator–Prey Models

“…The appearance of advection-driven heterogeneity in relation to single and multispecies ecological interactions was studied by Levin (1977), Levin and Segel (1976), Okubo (1980), Mimura and Murray (1978), Mimura and Kawasaki (1980), Mimura and Yamaguti (1982) and many other authors. These studies form a theoretical basis for modelling complex spatio-temporal dynamics observed in real systems (e.g., Badaev et al 1998).…”
