Abstract

In this study, we investigate a moving behavior of the network which is observed before an amoeba turns into ‘fruiting bodies’, namely it sporulates. More specifically, we observe how <i>Physarum polycephalum</i> behaves after a severe environmental change; exposure to certain strong light. Through systematic, controlled experiments (in constant dark condition, 26°C) we obtained four evidences, suggesting an efficient mechanism of the network's moving by which <i>Physarum polycephalum</i> makes the sporulation more effective, which is considered to be important for its survival. Our finding adds a new knowledge to the biological aspect of network science.
