| Research Abstract |
To investigate competition between alien and domestic pond turtles, experiments and field observation were carried out. I found that (1) adult domestic turtles may be able to survive under competition with alien turtles but juveniles may not, and (2) there was ecological segregation in areas used by each turtle species according to season : domestic turtles used shallow areas earlier than alien turtles. These findings suggest that adult domestic turtles can coexist with alien turtles but juvenile domestic turtles may be excluded under competitive condition.
