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”).
