Table 1. Q₁₀ values of heart rate in different life-history stages in two species of turtles, Chrysemys picta and Graptemys pseudogeographica kohnii.

	20–25°C	25–30°C	30–33.5°C
Chrysemys picta
Embryo, Day 15	2.20	1.83	1.79
Embryo, Day 40	2.19	1.74	1.85
Hatchling, Day 1	1.87	1.40	1.42
Hatchling, Day 10	1.55	1.49	1.72
Graptemys pseudogeographica kohnii
Embryo, Day 15	2.38	1.63	1.51
Embryo, Day 40	2.64	1.78	1.62
Hatchling, Day 1	1.78	1.58	1.35
Hatchling, Day 10	1.39	1.84	1.35

In most cases, Q₁₀ values of heart rate in embryos were higher than those of hatchlings.
