【 摘 要 】

Ecologists applying capture-recapture models to animal populations sometimeshave access to addition information about individuals' populations of origin. For example,tests that assign an individual's genotype to its most likely source population are increas-ingly used. Here we show how to augment a super population capture-recapture model withsuch information. We consider a single super population model without age structure, andsplit the entry probability into separate components due to births in situ and immigration.We show that it is possible to estimate these two probabilities separately. We first considerthe case of perfect information about population of origin, where we can distinguish individ-uals born in situ from immigrants with certainty. Then we consider the more realistic caseof imperfect information, where we use genetic or other information to assign probabilitiesto each individual's origin in situ or outside the population. We use a resampling approachto impute the perfect origination assignment data based on the imperfect assignment tests.The integration of data on population of origin with capture-recapture data allows us todetermine the contributions of immigration and in situ reproeuction to the growth of thepopulation, an issue of importance to ecologists. Further, the augmentation of capture-recapture data with origination data should improve the preciesion of parameter estimates.We illustrate our new models with capture-recapture and genetic assignment test data froma population of banner-tailed kangaroo rats Dipodomys spectabilis in Arizona.In chapter 4, we evaluate the value of marine reserves for fisheries using tag-return,tag-recapture and telemetry models. We estimate the patch-specific fishing mortality, natu-ral mortality, and movement rates. We first focus on tag-return models for a two-site modelwith one area a marine reserve and one area a fishing area. We consider tag-return, tag-recapture and telemetry models in various combinations for two site models where one areais a marine reserve and one is subject to regular fishing. Then we illustrate our methodswith a comprehensive simulation study.
