Abstract
Current status of freshwater turtles inhabitation was surveyed in the Miura peninsula, Kanagawa Prefecture. 317 individuals of turtles were captured by a trap in summer from 2007 to 2008. The faunistic composition was summarized as follows: Trachemys scripta elegans recorded 173 individuals (54.6%), Chinemys reevesii recorded 97 individuals (30.6%), Chelydra serpentina serpentina recorded 14 individuals (4.4%), Mauremys japonica Chi. reevesii recorded 13 individuals (4.1%), Mau. japonica recorded 8 individuals (2.5%), Pelodiscus sinensis recorded 4 individuals (1.3%), Che. serpentina osceola recorded 3 individuals (0.9%), Macroclemys temminckii recorded 2 individuals (0.6%), Mau. mutica kami recorded 1 individuals (0.3%), Ocadia sinensis recorded 1 individuals (0.3%), T. scripta scripta recorded 1 individuals (0.3%). It was thought that almost all the T. scriptas were released individually, because juveniles were observed a few. It was concerned that C. reevesii in this area was an alien invasive species, because C. reevesii is available to intercross with Mau. Japonica and it cause vanishing genetic variation. Mau. Japonica, which is native species, was observed at few sites and that is why it was clarified that Mau. japonica was under a critical situation. We conclude that the inhabitation of freshwater turtles is influenced by the existence of an emerged plant, pool, and without bank protection at the habitat of rivers and ponds.
