Locomotor Performance in Juvenile and Adult Box Turtles (Terrapene carolina): A Reanalysis for Effects of Body Size and Extrinsic Load Using a Terrestrial Species

Abstract

vestigated the relationship between body size and locomotor performance. Sprint or burst speed in some iguanid and helodermatid species is mass independent (e.g., Garland, 1984; Beck et al., 1995), whereas sprint speed in some agamid and lacertid species increases with body mass (e.g., Garland, 1985; Avery et al., 1987). Within families of lizards, sprint speed is generally independent of body mass (Garland, 1982). Lizards and snakes with an increased natural load re-
