Interspecific Variation in Temperature Effects on Embryonic Metabolism and Development in Turtles

Table 2

VO₂ Q₁₀ values calculated at different stages of embryonic development in three turtle species. Stages are expressed as % of total incubation duration, followed by the number of days since oviposition. Q₁₀ values were calculated from VO₂s of turtles incubated at 26.5 and 30.5°C.
