John Swenson is a PhD candidate in the Komoroske Lab at the University of Massachusetts, Amherst using molecular tools to understand the population dynamics of living marine resources, with an emphasis on data‐poor taxa. DNA‐based methods have great potential to fill critical data gaps for data‐limited species. A particularly exciting development in recent years is close‐kin mark–recapture (CKMR), which uses genetic information to identify related individuals within a sample of the population, and then analyzes these relationships in a mark–recapture framework to give estimates of absolute abundance and other key demographic parameters for the population that can inform their management. This method is likely to be especially useful for long‐lived elasmobranchs (sharks and rays), many of which are data‐poor, but have life histories that allow for several simplifying assumptions in CKMR models.

史蒂文·伯克利（Steven Berkeley）海洋保护奖学金：2020年获奖者

约翰·斯文森（John Swenson）是麻省大学阿默斯特分校Komoroske实验室的博士研究生，他使用分子工具了解海洋生物资源的种群动态，重点是数据贫乏的类群。基于DNA的方法在填补数据受限物种的关键数据空白方面具有巨大潜力。近年来，特别令人激动的发展是近亲标记捕获（CKMR），它使用遗传信息来识别人群样本中的相关个体，然后在标记捕获框架中分析这些关系以提供绝对丰度的估计。以及其他可以帮助他们进行管理的人口统计指标。这种方法对于寿命长的弹bra（鲨鱼和and鱼）特别有用，其中许多都是数据贫乏的人，
