报告简介:

在地球演化历史上,经历了大陆板块漂移、高原隆起、河流袭夺改道、洋/海盆打开、地峡形成、火山岛隆起等地质事件,以及洋流重组、第四纪冰期和间冰期气候循环等海洋物理环境及全球气候事件。这些地质、气候事件,通过影响生物的栖息地,改变生物的空间分布和种群数量大小,并在生物的进化中留下烙印。本报告将从生物进化的角度,探讨生物和地球的协同演化历史。

In the earth history, some ancient geologic, climatic and oceanographic events, e.g., continental drift, rise of the Tibetan Plateau, rivers’ capture, sea basin’s opening, isthmus’ formation, volcanic island’s uplift, glacial cycles and sea currents change were thought to have influenced marine or freshwater species’ evolutionary history through changing these species’ habitat and population size. These palaeo-geologic or climatic events will be recorded in DNA information of organisms. This presentation will show us coevolutionary relationship between organisms and earth based on biogrographical history of several species.

何利军,华东师范大学河口海岸学国家重点实验室副研究员。研究专长为淡水和海洋动物谱系生物地理学、种群遗传学、种群资源动力学和古生态学。研究区域主要包括了中国海、印度洋-西太平洋、发源于青藏高原的河流(长江、澜沧江、红河、恒河、雅鲁藏布江等)。先后主持上海市自然科学基金,上海市科委科技创新行动计划“一带一路”国际合作项目和国家自然科学基金各一项,作为骨干参与两项国家重点研发计划项目和一项中国科学院战略性先导科技专项。

主要科学发现包括:东海区黑潮和台湾海峡对于弹涂鱼跨区域基因流的隔离作用;东海日本带鱼有效种群数量的变化受到夏季风影响,南海带鱼有效种群数量受到冬季风影响;印度西太平洋广泛分布的锯缘青蟹的起源及其随洋流的扩散过程。

Lijun He, associate professor in State Key Laboratory of Estuarine and Coastal Research, East China Normal University. Research interests include phylogeography, population genetics, population dynamics of freshwater or marine species, and ancient ecology in ocean. His research area covers the China seas, Indo-West Pacific and some rivers originating from the Tibetan Plateau (e.g., Yangtze River, Mekong River, Red River, Ganges River and Brahmaputra River). His research was financially supported by Shanghai Natural Science Foundation, One Belt, One Road International Cooperation Project of Shanghai's Science and Technology Innovation Action Plan, Natural Science Foundation of China, National Key Research and Development Program.

His studies in evolutionary biology have revealed some interesting biogeographical histories of different marine species including (i) The Kuroshio Current and the glacial exposed Taiwan Strait played significant roles of physical barrier to restrict migration of mudskipper among the coastal Japan, East China Sea and South China Sea; (ii) Effective population sizes of cutlassfish (Trichiurus japonicus and T. nanhaiensis) in the East China Sea and South China Sea were controlled by the Summer Monsoon and Winter Monsoon, respectively; (iii) Mud crab (Scylla serrata)’s westward dispersal across the Indian Ocean from Northwest Australia and sequential colonization along coasts of the northern Indian Ocean and West Pacific are closely related to the circulations in the Indo-West Pacific.
