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: - How many walleyes are there and where do they move in Mille Lacs,Minnesota? Does fish length affect the survival or movement patterns? - Where do fish move along the coast of British Columbia? How can you estimate the various movement rates? How are these estimates adjusted for tag loss through radio tag failure?

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。这项研究的动机是生态学家遇到的实际问题。很多研究都涉及捕捉-再捕捉实验。在这些实验中，动物被捕获、贴上标签、释放，然后再被捕获。捕获和再捕获的模式使研究人员能够估计种群中存在的动物存活率和数量。我的两个研究问题是：-在明尼苏达州的Mille Lacs，有多少眼鲨？它们会搬到哪里去？鱼的长度是否影响生存或运动模式？-鱼沿着不列颠哥伦比亚省的海岸往哪里游？你如何估计不同的移动速率？如何根据无线电标签故障造成的标签丢失调整这些估计？
