Natural Resource BiometricsMark and Recapture MethodsJollySeber Method: (Multiple marking)JollySeber method extend the mark and recapture method to open populations. The biggest change in the sampling procedures over the Schnabel method is the inclusion of the information of when a marked individual was last captured. Advantages:
Alpha hat at time t is a estimate of the proportion of the population that is marked. M_{t }s an estimate of the marked population just before sample time t. N_{t} is an estimate of the populations size at time t. The dotted section represents the Z_{6} area and the gray section represents the R_{6 }area.
