Figure 3.

Pie chart representing the publication volume associated with each topic discussed in this review since the publication of the seven ant genomes. The numbers correspond to the number of studies investigating each topic, including the original genome papers and all publications on social insects citing the genome papers (reviews excluded). The category 'other' incorporates studies of topics that were not discussed in this review (such as sex determination, aging, circadian rhythms, invasiveness, metabolism and neurobiology), as well as studies focusing on social insects but not in a sociobiological context.
