A research group led by lecturer Taiga Kunishima of the Department of Applied Biological Sciences of Faculty of Agriculture , Setsunan University (President: Yasuyuki Kubo) and curator Kento Takada of the Wakayama Museum of Natural History (Director: Keiji Wada), including Professor Kando Nishikawa of the Graduate School of Global Environmental Studies, Kyoto Graduate Schools, and research team leader Ryo Iguchi of the Nature Positive Technology Implementation Research Center, National Institute of Advanced Industrial Science and Technology, has clarified the detailed genetic population structure of the Japanese crayfish, a well-known and familiar aquatic creature, by genetic analysis using a next-generation sequencer. Furthermore, based on the genetic population structure, the regionality of the body color type of the crayfish was examined. The results of this study will serve as the basis for future research on the classification, phylogeny, and population structure of crayfish, and will be important knowledge for understanding how the distribution of inland water creatures in the Japanese archipelago has been shaped.
