The capture process

Conditional on an individual being exposed to trapping, we assume constant probability of capture,

Pr(capture|exposure) = p0, where p0 is a parameter to be estimated. Thus, the apparent probability of capture for an individual having activity center sj is

We see that heterogeneity in apparent capture probability is induced by heterogeneity in exposure through . The heterogeneity in capture probability induced by spatial location relative to the trapping array can thus be described as a scaling (by p0) of Figure 7.6.
