| Research Abstract |
Distribution and intra- and inter-populational geneticdiversities of the Anderson's crocodile newt, Echinotriton andersoni, were investigated by field observations and by variation of mitochondrial DNA genes, respectively. Results indicated a relatively large genetic differentiation between populations of Amami and Okinawa Groups, non-monophylies of northern, central and peninsular populations of Okinawajima, and a closer relationship of southern Okinawajima population with Tokashikijima population than with other Okinawajima populations. Our results also suggested a genetic uniformity of sotlthern Okinawajima population.
