Figure 2. a) Very few untreated nests shared with treated nests, regardless of social form. Plot includes the status of an isotope tracer in untreated nests by social form according to Gp-9results. b) All untreated nests that shared were within 5m of the treated nest. Plot includes status of an isotope tracer in untreated nests by distance in meters to the treated nest. c) All untreated nests that shared showed very low pairwiseF ST values with the treated nest. Plot includes status of an isotope tracer in untreated nests by pairwiseF ST values compared to the treated nest. Results shown are from all six sites. Nests with \(\delta\)15N values greater than 20‰ indicated that untreated nests exchanged workers and/or resources with the treated nest (“Shared”), and the values of all other nests indicated that untreated nests did not exchange workers or resources with the treated nest (“Did not share”).
