Model	Survival	Recapture	k (SE)	WAIC (SE)	Slope (SE)
M0	I	t * m	59.8 (2.8)	1,449.8 (46.4)
M1	I	t + m	48.9 (2.7)	1,437.4 (47.6)
M2	I	effort + m	20.7 (1.0)	1,852.9 (45.2)
M3	HWI	t + m	45.4 (2.7)	1,370.2 (46.7)	+0.774 (0.100)
M4	Size	t + m	46.4 (2.7)	1,393.3 (46.6)
M5	r(socialgroup)	t + m	57.8 (3.0)	1,377.2 (47.6)
M6	HWI + r(socialgroup)	t + m	53.0 (2.8)	1,340.6 (46.8)	+0.925 (0.133)
M7	size + r(socialgroup)	t + m	55.5 (2.9)	1,362.0 (47.1)
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.
