Abstract: Western painted turtles from populations in the northern portion of their range attained greater sizes, had more rapid growth despite a shorter growing season, and appeared to mature at a larger size than turtles from farther south. Mean clutch size was 19.8, with no evidence of production of two clutches. Examination of stomach contents showed that the turtles were mainly carnivorous, even in areas of abundant vegetation. The carnivorous diet may account for the large sizes, large clutches, and rapid growth of the turtles and may permit C. picta to maintain populations farther north than other North American turtle species.
