Effect of B. chinensis on other ant species. (a) There was a significant negative relationship between the number of B. chinensis nests and the number of nests of other ants found at the same point (χ 2 = 29.68, P < 0.0001), while marginally non-significant in Japan (χ 2 = 3.84, P = 0.05; likelihood ratio test). (b) There was a significant negative relationship between the number of B. chinensis nests and the number of the other ant species found at the same point (χ 2 = 11.99, P < 0.001), while there was no significant relationship in Japan (χ 2 = 1.51, P = 0.22; likelihood ratio test). The size of each plot is proportional to the number of data points it represents.
