Mark–recapture studies utilize statistical techniques to estimate population parameters. Over k sample times, individuals are captured, tagged with unique tags, released and potentially recaptured at subsequent sampling times. The Jolly–Seber model (Jolly, 1965; Seber, 1965) is used to model open populations since it …
