The patterns of social interactions between human beings or social animals can be represented by complex networks exhibiting a wealth of distinctive topological properties. Among those, recent research activity has been focused on understanding their heterogeneous character, their temporal properties, or the multiplex nature of the interactions. In this talk, we will review the main topological features exhibited by social networks defined by human or animal social interactions, focusing on the effects that such features have on dynamical processes developing on top of them. In particular, we will consider three main scenarios: Searching in temporal multiplex networks; the spread of information in polarized political discussion networks; and flocking dynamics in social animal networks.
