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.


Self Introduction:

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.
