Table 1. Population demographic parameters for Crotalus willardi obscurus (= CWO) in the Animas Mountain sky island compiled by life history stage and population.

Comparison	df	Survival	Capture	Pop. Size
Male vs Female	141	6.65**	5.81**	7.40**
Male vs Juvenile	121	11.46**	4.66**	1.91**
Female vs Juvenile	63	0.041	0.044	1.31
Adult vs Juvenile	190	13.77**	4.91**	0.78

Comparison = Life history stages evaluated; df = degrees of freedom; Survival = F-value for comparison of survival by life history stage; Capture = F-value for comparison of capture probability by life history stage; Pop. Size = F-value for comparison of population size by life history stage.

** = Statistical significance at P < 0.05.
