Fig 3 . Average number of workers competing for resources
between W. auropunctata (red) and native ant species in Mexico.
Baits were placed at the boundaries of territorial patches (10
replicates). Top graphs interactions between W. auropunctata
(red) and ground foraging ants S. geminata (yellow) and P.
protensa (dark green). S. geminata is a superior competitor
(\(x^{2}\)=55.976, p<0.0001) , but W. auropunctata
displaces P. protensa on the ground
(\(x^{2}\)=15.641, p<0.0001). Bottom graphs show interactions
with the arboreal ants S. picea (cyan) and P.
synanthropica (light green) (\(\ x^{2}\)=9.839, p= 0.0017). W.
auropunctata gains a competitive advantage against S. picea, but
losses against P. synanthropica in the trees
(\(x^{2}\)=69.03, p< 0.0002).
