0130543LeeThis project focuses on geographic pathways and genetic mechanisms of invasions by the zebra mussel, Dreissena polymorpha. Objectives of this study are to (1) reconstruct pathways of invasions, from potential sources in the Caspian and Black Sea region to North America, (2) clarify genetic (evolutionary) relationships among sibling species and identify which subspecies are invasive, and (3) describe genetic traits of the invasive subspecies. Using genetic markers, a genealogy (phylogeny) will be constructed to determine pathways of invasions and genetic relationships among physiological races of zebra mussels. For this purpose, sensitive genetic markers (AFLPs) and powerful data analysis software (Dominant Marker Analysis Package) are currently under development. This project will also involve collaborative efforts with scientists at the Russian Academy of Sciences, including a joint research cruise on the Caspian Sea to collect from sites where the zebra mussel species complex has probably evolved.The zebra mussel ranks among the most hazardous exotic species that has entered North American waters, with an economic impact in the billions of dollars. Despite intense ecological interest and efforts toward mitigation, little effort has been devoted toward understanding genetic and physiological mechanisms of zebra mussel invasions. We do not know origins of North American populations, their genetic traits, and why they are so successful as invaders. Information from this project will enhance our predictive power on range expansion and adaptive potential during invasions. In addition, as pathways of invasions tend to be shared by multiple species, information from this project will yield insight into general principles on mechanisms of invasions.

0130543李本项目的重点是斑马贻贝（Dreissena polymorpha）入侵的地理途径和遗传机制。 本研究的目的是（1）重建入侵途径，从里海和黑海地区的潜在来源到北美，（2）澄清兄弟物种之间的遗传（进化）关系，并确定哪些亚种是入侵种，（3）描述入侵亚种的遗传特征。 利用遗传标记，将构建一个系谱（遗传学），以确定斑马贻贝的入侵途径和生理小种之间的遗传关系。 为此目的，目前正在开发敏感的遗传标记（AFLP）和强大的数据分析软件（显性标记分析包）。 该项目还将涉及与俄罗斯科学院的科学家的合作努力，包括在里海进行联合研究巡航，从斑马贻贝物种复合体可能进化的地点收集斑马贻贝，斑马贻贝是进入北美沃茨的最危险外来物种之一，经济影响达数十亿美元。 尽管强烈的生态利益和努力缓解，很少有人致力于了解斑马贻贝入侵的遗传和生理机制。 我们不知道北美种群的起源，他们的遗传特征，以及为什么他们作为入侵者如此成功。 来自这个项目的信息将提高我们在入侵期间对范围扩展和适应潜力的预测能力。 此外，由于入侵途径往往由多个物种共享，因此该项目的信息将有助于深入了解入侵机制的一般原则。
