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 that not only provide humans with good animal protein, but also play an important role in the marine ecosystem. Cephalopods are widely distributed in the three oceans and the polar waters. They have a wide range of distributions and a wide range of species. It is of great significance to explore their spatial distribution patterns and evolutionary history at the molecular level. The history of molecular phylogeography was introduced, and the theoretical basis and practical basis of molecular phylogeography were described. This paper reviews the progress of the research on molecular phylogeography of cephalopod. It mainly summarizes the genetic structure, phylogeographical pattern and influencing factors of cephalopods, discusses the distribution pattern of cephalopod from the perspective of phylogeny, and finally puts forward the existing problems And make a forecast and analysis.
