Figure 1.

An example of a wildlife network: the Serengeti lion network [4]. In the within-pride network, the nodes (circles) are individuals and edges (lines between circles) are contacts observed on a short time scale (this is a cartoon, not based on data). The between-pride network is derived from behavioral observations of individually known lions as in [4] where nodes represent prides, and edges represent contacts between prides. The histogram represents the degree distribution of the between-pride network.
