Table 1. Top model results from a candidate model set using tuatara survey data from 1998 – 2011 analyzed using an open mark-recapture population model.

Model Structure
Survival	Capture Probability	AICc	ΔAICc	K	w	−2Log(L)
T	sex + time	6195.3	0	19	0.490	6157.0
T + sex	sex + time	6196.1	0.79	20	0.331	6155.8
T * sex	sex + time	6197.4	2.10	21	0.172	6155.1
time	sex + time	6205.5	10.13	32	0.003	6140.6
sex + time	sex + time	6206.4	11.04	33	0.002	6139.5

Survival was modeled testing all combinations of sex- and time-dependent effects, including either an interaction (sex*time) or additive effects (sex+time). Temporal variation in survival was also modeled as a linear trend (T). Capture probability was modeled to include the effects of sex, time, sex+time, or constant. The top models gaining the majority of support are shown in bold. The rankings of the full model set can be found in File S1.
