Fig. 4. Relative apparent survival rate (ratio of apparent annual survival in freeway populations to apparent annual survival in control populations) of male and female squirrel gliders (Petaurus norfolcensis) in southeast Australia, 2005–2008. The open circle is the mean estimate with vague priors; the shaded circle is the mean estimate with informative priors for apparent survival in control populations. Bars are 95% credible intervals.
