<p>A: Capture probability density function (pdf) for Model I, , given a population size <i>N</i> = 500: line for <i>θ</i> = 1.5, dashed line for <i>θ</i> = 2.5, and dot dashed line for <i>θ</i> = 3.5. The skew of the capture probability distribution increases as the parameter <i>θ</i> increases. B: Capture probability density function (pdf) for Model II, , given a population <i>N</i> = 500: line for <i>α</i> = 1, <i>β</i> = 3.0; dotted line for <i>α</i> = 2, <i>β</i> = 5 (skewed bell-shape); thick dashed line (bell-shape) for <i>α</i> = 2, <i>β</i> = 2; dashed line (U-shape) for <i>α</i> = 0.5, <i>β</i> = 0.5; and dot dashed line for <i>α</i> = 5, <i>β</i> = 1.0. An array of capture probability distributions can be generated by changing parameters <i>α</i> and <i>β</i>.</p
