CAREER: Origins and Evolution of an Endemic Arctic Freshwater Crustacean

该项目将调查岛国和相对年轻的北极湖泊和池塘的遗传变异和多样性。将检查地方性多倍体甲壳动物(博斯米纳)。来自北极多倍体谱系和10个温带亲本分类群的个体将被用于研究共显性核标记、简单序列间重复序列、28D RDNS序列、线粒体DNA序列和形态。湖心将被用来研究地质时期个体的形态。这些结果将有助于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“决心”加拿大分校开设本科大学实地课程。

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.
