|
This study investigated the effects of temperature on the aquatic and terrestrial locomotor performance and growth effects on the scaling relationship between measures of performance and body mass in western painted turtles, Chrysemys picta bellii. Measures of locomotor performance and righting performance increased as temperature increased. Locomotor performance measures were highly correlated with one another and repeatable over time. The righting response was not correlated with any other measure of performance. Initially, measures of locomotor performance of hatchling turtles displayed positive scaling with body mass. However, the scaling of aquatic and terrestrial burst speed with body mass declined at each measurement interval over the 30-week period as a result of ontogenetic changes associated with growth. This suggests that if locomotor performance is under strong selection, larger hatchlings may have distinct advantages over smaller conspecifics; however, if smaller hatchlings do survive, such advantages may be reduced or lost over time.
