Table A1.

Results of pre-network randomization tests that compared the observed mean strength of macaques within their grooming networks, with a distribution of mean values calculated from 1000 permuted networks generated by randomly swapping the edges of the original networks.

Group ID	Number of nodes (females)	Mean strength (pre-introduction)	Mean strength (post-introduction)
I	40	27.78^**
II	30	34.92^**
III^a	14	27.43^**	21.57^**
IV^a	14	26.43^**	27.43^**
V	14	29.23^**	24.92^**
VI	18	21.88^**
