Is heterogeneity of catchability in capture–recapture studies a mere sampling artifact or a biologically relevant feature of the population?

摘要: The heterogeneity of catchability (HC) among the individuals encountered during a capture–recapture study has long been regarded as liability. However, heterogeneous capture probabilities may reflect interesting but hidden features population, such social status. difficulty is to distinguish between this intrinsic and extrinsic induced by itself. So far, population ecologists have not able these two sources variation in because, presence data, they frequently used too simple approach. This traditional approach, which consists incorporating common lack fit (transience trap-dependence), does directly model HC thus cannot investigate its biological meaning. In context, we propose, for open populations, employing multievent models. Multievent models make it possible break into classes viewed uncertain states. With introduction coefficient proportional over time classes, our approach allows investigation parsimonious way. paper, apply both new long-term data set male deer mice Peromyscus maniculatus. We then compare 13 candidate separately each Our results indicate that superior
