Figure 3. Social regulatory networks.

Triad significance profiles compare the characteristic network motifs across a diverse range of network types and sizes by plotting standardized Z-scores which quantify the extent to which each subgraph is observed more or less frequently than expected in networks of a similar size and global structure but with randomized edge connections. The observed P. californicus social insect networks exhibit a distinct pattern of social regulatory structure combining elements found in previously identified major network superfamilies [22].
