9.108) is an attempt to cope with the problem that some animals are more vulnerable to capture than are others. Heterogeneity in the individual vulnerability of animals can effectively change the vulnerability coefficient over time. For instance, changes in moon phase can result in dramatic changes in the behavior of pocket mice ( Perognathus spp.) and kangaroo rats ( Dipodomys spp.), where predation by owls is enhanced in moonlit nights. Even then, subtle environmental changes can induce changes in animal behavior. The timing of the removal study should therefore be planned with weather forecasts in mind. This assumption can be violated if weather factors, which influence animal behavior, are not constant during the k -removal periods. 9.91) also assumes the vulnerability or catch coefficient ( c) is constant across sampling periods. Instead the catch data will need to be purposefully collected under experimental conditions. This precludes use of the constant-effort model in the analysis of traditional harvest data. Only under controlled conditions will effort likely be held constant. 9.97) is a special case of the variable-effort model ( Eq. Millspaugh, in Wildlife Demography, 2005 Discussion of Utility For small mammals, only species with enough detections to determine directional response are reported.
