Evolution of song communication in a 2D space

Abstract

Song communication of artificial birds is simulated in a 2D space, in which male and female birds communicate and then leave their offspring based on their communication performance. The communication is modeled as interaction between different types of finite-state automata, one for song production by males, the other is for song evaluation by females. In addition, an abstract space is introduced for studying how spatial structure affects the evolution of song communication system. We find a correlation between global spatiotemporal patterns and local communications between artificial birds. In particular, we report a habit segregation phenomenon of our simple ecosystem. © Springer-Verlag Berlin Heidelberg 2005.
