Abstract
1.
1.Snapping turtle hatchings raised at 25°C ate freely and grew from 7.4 to 50.7 g in 1 year, while those at 15°C ate little and did not grow.
2.
2.Selected body temperature in a terrestrial gradient were similar for 15 and 25°C in fall/winter and spring (if
X
̄
=24.6°
C
). In spring, turtles from 15 and 25°C had similar selected temperatures in an aquatic temperature gradient (if
X
̄
=28.0°
C
).
3.
3.The CTM of 25°C turtle was significantly higher ((if
X
̄
=41.1°
C
) than that of 15°C turtles (if
X
̄
=39.1°
C
). We transferred the 15°C turtles to 25°C and the 25°C to 15°C. After 1 week the CTMs were the same. When transferred for 3 weeks, 15–25°C turtles had a significant higher CTM (if
X
̄
=41.4°
C
) than 25-15°C turtles (if
X
̄
=39.6°
C
).
4.
4.Thus, the CTM is directly related to acclimation temperature but selected temperature is independent of acclimation temperature, growth rate and age.
