Research Highlights 研究亮點 51 Several HongKongBranch research teamshave collaborated and decoded the demographic history, genetic structure, and populationconnectivityofadeep-sealimpetwidelydistributed in vent and seep ecosystems in the Northwest Pacific for the first time. This study not only enhances our knowledge of the historical population divergence and contemporary gene flow of deep-sea organisms under the intricate interactions amongst local habitats, seafloor topography, and ocean currents, but also serves as a scientific basis for better conservation of marine biodiversity and more effective environmental management. The research findings were published in the international academic journal Molecular Biology and Evolution. “Population connectivity is a critical criterion in assessing the biodiversity conservation value of any particular habitat as stipulated by Convention on Biological Diversity (CBD), International Maritime Organization (IMO) and other United Nations (UN) agencies, along with various international organizations. Therefore, we anticipate the results of this study will deepen our understanding of the demographical mechanisms and population connectivity of deep-sea organisms, lay a foundation for the conservation of marine biodiversity and sustainable utilization of marine resources, and pave the way for the establishment of regional environmental management plans as well as the designation of marine protected areas in global ocean,” said Prof. Qian, also David von Hansemann Professor of Science.
