According to a physiological hypothesis, we expect lizards with autotomized tails to show higher body temperatures that allow them to regenerate lost tissues faster, at least when the thermal environment is not limiting (at mid and low elevations). By contrast, according to an ethological hypothesis, we expect lizards with autotomized tails to avoid exposure to predators by reducing thermoregulation time, thus showing lower temperatures than lizards with non-autotomized tails.
