| summary | The term of self-organizing was originally introduced by Ross Ashby[1] in 1947, who was an English psychiatrist and also a pioneer in cybernetics. Nowadays, self-organizing behavior has been observed in many disciplines in not only natural sciences but also social sciences such as social information[3] and economics[4].
Turning to biology, especially to developmental biology, our understanding of regulated but complex patterns in biological systems has been deepened over the past ten years. Especially, collaborative research of experimental and theoretical works has gradually discovered the mechanism how self-organized complex patterns are generated in far from equilibrium systems. It has been reported that genetics does not always reveal the occurrence of such patterns and even simple systems may generate regular as well as chaotic irregular patterns in a self-organized way. Particularly, self-organized patterns” are observed in biological systems. In this talk, I will talk on, localized patterns in dryland vegetation arising in ecosystems.lectif. |
