2.5 | Within-colony relatedness of fire ants in the
literature
We also compiled all published coefficients of within-colony relatedness
between workers in the red imported fire ant to compare our results with
those in the literature. We searched the Web of Science using the
following search terms: βSolenopsis invicta β OR βred
imported fire antβ AND population AND microsatellite .
Our search generated 87 records, but a large number of these studies
focused on a different ant or social insect species. We excluded any
study that contained only queen-queen relatedness coefficients, as well
as any study of a different species of ant or social insect. We reviewed
each record and extracted within-colony relatedness coefficients between
workers (means and standard error whenever available) and recorded the
sampling location. In total, we extracted information from eight
studies.
