Workshop on Pattern Formation and Functional Morphology, Fri, 11 Jan, 2008
Speaker: Toshio Sekimura
Abstract
Color pattern formation in animals is one of the most spectacular and important themes for the study of development and evolution of organisms. In particular, I will focus on pigmentation pattern formation in butterfly wings and fish skin surface. In my talk, I will show that a reaction-diffusion system is enough to realize and simulate color pattern formation in both butterflies and fishes.
It is generally known that the formation mechanism of color pattern includes not only one specific factor, but also some key factors to understand its biological reality such as gene activity factor, as well as biochemical, developmental, ecological factors, and so on. However, current research activities of color pattern formation seem to be somewhat far from the goal or integrative methodology of research. As a first step, in addition to mathematical and computational analysis of a reaction-diffusion system, I will extend my idea to an integrative aspect, which systematically includes some key factors to understand its biology.
