| Research Abstract |
Intraspecific genetic and ecological divergence has been elucidated along the Japanese coast for 5 brackish-water crabs of Uca arcuata, Macrophthalmus banzai, Deiratonotus cristatus, Deiratonotus kaoriae, and Ptychognathus ishii. Most of them had distinct genetic divergence between the Japanese mainland and the Ryukyu Islands, concurrent with ecological divergence of breeding season. Within the Japanese mainland, distinct differentiation was also found between the Japan Sea coast and the Pacific coast in D. cristatus and between Kyushu and the Kii Peninsula in D. kaoriae.
