This project will investigate genetic variation and diversity in insular and relatively young Arctic lakes and ponds. The endemic polyploid crustacean (Bosmina) will be examined. Individuals from among the Arctic polyploid lineages and 10 temperate parent taxa will be used for studies of co-dominant nuclear markers, inter-simple sequence repeats, 28D rDNS sequences, mitochondrial DNA sequences, and morphology. Lake cores will be used to examine morphologies of individuals over geological time. These results would allow an identification of ancestors of the Arctic lineages and would constrain the mechanisms leading to observed diversity. An educational component would involve the establishment of an undergraduate college field course at Resolute Canada.

该项目将调查岛屿和相对年轻的北极湖泊和池塘的遗传变异和多样性。 将对特有的多倍体甲壳类动物（Bosmina）进行检查。 来自北极多倍体谱系和10个温带亲本类群的个体将用于共显性核标记、简单重复序列间、28D rDNS序列、线粒体DNA序列和形态学的研究。 湖芯将被用来检查个人在地质时期的形态。 这些结果将允许确定北极血统的祖先，并将限制导致观察到的多样性的机制。 教育部分将涉及在加拿大Resolute设立一个本科学院实地课程。
