Results of assortativity analyses on weighted social networks within Marley using the nearest-neighbour (NN) method (duplicated associations removed)

Network type	Male					Female
	No. of links	Mean assortment		Effect size	P	No. of links	Mean assortment		Effect size	P
	No. of links	Observed	Permuted	Effect size	P	No. of links	Observed	Permuted	Effect size	P
3-NN	58.4	0.144	−0.032	0.175	0.014	90.6	0.001	−0.024	0.025	0.654
5-NN	98.7	0.090	−0.028	0.118	0.032	146.3	0.031	−0.022	0.053	0.230
7-NN	135.6	0.106	−0.027	0.134	0.006	200.6	0.034	−0.022	0.056	0.138

The observed and null assortment scores (averaged across all 6 years) are based on weighted networks, with values in bold indicating significance at α = 0.05. The permuted assortment represents the mean of 1000 randomizations according to the null model. Repeated links across years were deleted over 1000 randomizations and the median P value is reported (since this proved most robust to type I and II errors).
