N2 - Some organisms, including fungi, ants or slime molds, explore their environment and forage by forming interconnected networks. The plasmodium of the slime mold P.polycephalum is a large unicellular amoeboid organism which grows a tubular spatial network through which nutrients, body mass and chemical signals are transported. Individual plasmodia are capable of sophisticated behaviours such as optimizing their network connectivity and dynamics using only decentralized information processing. In this study, we used a population of plasmodia which interconnect through time, in order to analyse the dynamical interactions between growth of individual plasmodia and global network formation. Our results showed how the initial conditions, such as the distance between plasmodia or their size, as well as the presence and quality of food affect the emerging network connectivity.© 2016, IOP Publishing.
