西北太平洋边缘海重要海洋动物分子系统地理学的研究进展

伴随溯祖理论(coalescent theory)的日益完善和分子生物学技术的不断创新,具有学科交叉性的分子系统地理学已成为国际上十分活跃的研究领域,其成果对现今的种内遗传格局、物种形成、生物多样性水平等研究有重要的启示。西北太平洋的边缘海约占世界边缘海的75%,其显著的历史地理过程和复杂的海洋水文环境为海洋生物遗传分化和物种系统地理格局的研究提供了良好的模型。本文对近年来西北太平洋边缘海重要海洋动物门类的分子系统地理学进行简要综述,以期加深对相关物种的遗传多样性水平及种群进化历史的认识,为海洋生物资源的合理开发利用和保护提供必要的理论指导;同时,本文还对分子系统地理学今后的研究重点及其所使用的技术手段进行更深层次地展望。

Molecular Phylogeography of Marine Animals in Marginal Seas of the Northwestern Pacific: A Summary and Prospectiveness

Accompanied by the increasing improvement of coalescent theory and continuous in-novation in molecular biological techniques,the molecular phylogeography,has become active international research fields with interdisciplinary nature.And the research achievements have brought important revelation to present studies of intraspecific genetic pattern,speciation and biodiversity.Over 75% of the marginal basins in the modern global ocean are concentrated in the Northwestern Pacific continental margin.These marginal seas have extensive latitudinal range,well-characterized oceanography and dramatic geological history,which provides one of the best model systems for marine biogeographical research.Here we review researches of the intraspecific phylogeography of major marine animals in marginal seas of the Northwestern Pa-cific,with the aim to deepen the understanding of genetic diversity and population evolution history and to provide the necessary theoretical guidance for protection and reasonable utilization of the living marine animals.Meanwhile,further prospects are highlighted on the future research emphasis and the technical means of molecular phylogeography.
