Fig. 2. Apparent annual survival rate of male squirrel gliders (Petaurus norfolcensis) in control and freeway populations. Open circles are mean estimates with vague priors; shaded circles are estimates with informative priors. Bars are 95% credible intervals. Survival period refers to either of two time intervals over which apparent survival rates were estimated. The first survival period includes trap sessions between August 2005 and December 2006; the second includes sessions between January 2007 and February 2008.
