Capture-recapture modelling of population dynamics.

这项研究涉及使用统计学和数学来研究动物种群的动态和其他生态问题。这项研究是由生态学家遇到的实际问题推动的。大部分研究都涉及捕获-再捕获实验。在这些实验中，动物被捕获、标记、释放，然后再被重新捕获。捕获和重新捕获的模式使研究人员能够估计存活率和种群中存在的动物数量。 我的两个研究问题是： -研究不列颠哥伦比亚省东南部灰熊的种群动态。熊将毛发样本留在诱饵站。对这些样本的DNA分型相当于捕获和重新捕获动物。将开发空间-显式捕获-再捕获模型，以说明采样事件之间在整个景观中缺乏完全混合。 -研究不列颠哥伦比亚省太平洋沿岸鲱鱼迁徙的变化。自20世纪30年代初，S在鲱鱼产卵地对鲱鱼进行标记和回收。标签回报可以用来估计产卵区之间的交换率。贝叶斯P-样条法和分层模型将被用来模拟交换率随时间的变化。

This research involves the use of statistics and mathematics in studying the dynamics of animal populations and other ecological problems. The research is motivated by real problems encountered by ecologists. Much of the research involves capture-recapture experiments. In these experiments, animals are captured, tagged, released and then subsequently recaptured. The pattern of captures and recaptures enables the researcher to estimate survival rates and the number of animals present in the population. Two of my research questions are: - Studying the population dynamics of grizzly bears in southeast British Columbia. Bears leave hair samples at bait stations. The DNA typing of these samples is equivalent to capturing and recapturing the animals. Spatially-explicit capture-recapture models will be developed to account for lack of complete mixing across the landscape between sampling events. - Studying the changes in herring migration in the Pacific coast of British Columbia. Herring have been tagged and recovered since the early 1930's on their spawning grounds. The tag returns can be used to estimate interchange rates among spawning areas. Bayesian P-spline and hierarchical models will be used to model changes in interchange rates over time.
