摘要
头足类是重要的经济海生动物,不仅为人类提供了优质的动物蛋白,而且在海洋生态系统中扮演着重要的角色。头足类广泛分布在三大洋和极地海域,分布范围广,种类繁多,从分子水平上探讨其空间分布格局及进化历史具有重要的意义。介绍了分子系统地理学的发展史,并阐述了分子系统地理学研究的理论基础和实践基础。回顾了头足类分子系统地理学的研究进展,主要对头足类种群遗传结构、系统地理格局及其影响因素进行概括,并从系统进化的角度探讨头足类的分布格局,最后提出存在的问题并进行展望与分析。
Cephalopods are important economic marine animals not only because of high quality animal protein they supply for people, but also an vital role they play in the marine ecosystem. It is of important significance to explore their spatial distribution patterns and evolutionary history from the molecular level as cephalopods are distributed widely in three oceans and Polar seas with a great variety of species. This paper introduced the history of molecular phylogeography briefly, and illustrated its theoretical principle and practical basis. It reviewed the research progress in molecular phylogeography, and summarized population genetic structure of cephalopods and phylogeographic patterns as well as factors that influenced them. Distribution patterns of cephalopods were also disscussed from the point of view of molecular phylogeny, and the existing shortage was put forward followed by with several prospects and analysis.
