Symposium 22: Structure, function and dynamics of social networks
The essence and success of social insect colonies lie in the intricate functional links that connect the numerous colony members with each other. These links facilitate the exchange of information and materials, but could also make the colony vulnerable to attack from pathogens that could use these links to spread rapidly. Therefore, it seems likely that the network structure of the colony is probably a product of strong but opposing selection pressures. Of late, the dynamics of social networks have been of enormous interest to areas ranging from computer science to epidemiology, and the challenge to build efficient networks that are also stable to invasion by foreign agents has been a dominant focus of research. Social insect colonies, which are not only more experimentally amenable than many other complex systems but are also products of natural selection, could provide a powerful test of theories of network dynamics. In this symposium, we will discuss social insect colonies as examples of efficient and resilient networks.
