| Abstract |
|
A total of 437 Chrysemys picta marginata were caught in the Wye Marsh area between May 1978 and October 1983. The sex ratio of males to females to juveniles was 1:1.39:0.54. Males reached sexual maturity at about 89 millimeters plastron length, females at about 126 millimeters. The relationship between age and length of turtles was non-linear. Growth showed a marked decrease following attainment of sexual maturity. Females were larger than males in all age classes above 5 years. Some notes on nesting are provided and the first Ontario record of second clutch laying in the Painted Turtle is reported.
