M8 I t + m + r(socialgroup) 94.9 (4.3) 1,314.1 (45.2)
M9 HWI t + m + r(socialgroup) 81.8 (3.9) 1,261.8 (45.3) +0.731 (0.100)
M10 HWI + size t + m + r(socialgroup) 80.0 (3.8) 1,252.7 (45.2) +0.645 (0.103)

Fixed effects considered were: i, constant parameter; t, time effect; m, trap-dependence effect; HWI, association index effect; size, social group size effect. r(socialgroup) represents the social group random effect; k is the estimated number of parameters in the model; + is an additive effect; * is an interaction effect.
