The Thermal Dependence of Lizard Behaviour
New techniques were utilized to measure burst speed and distance running capacity in six species of lizards and to examine the thermal dependence of these behavioural capacities. These behaviours were repeatable among groups of animals within a species, within a group during the experiments, and among individuals of a group. Burst speeds averaged 130 to 150 m/min for active species, with some i...
متن کاملThermal Dependence of Sprint Performance of the Lizard Sceloporus Occidentals
Sprint velocity of the lizard Sceloporus occidentalis was maximal at preferred body temperature (Tb, 35°C). Mean running velocity (VR) and stride frequency (f) at this temperature were 3-23 ± 0-7 (mean ± S.E.M.)ms~' and 15-6 ± 0-3 s", respectively. VR and f did not change significantly when Tb was raised to 40°C. At T b values between 25 and 35°C the thermal dependencies of VR (Qio= 1'23) and f...
متن کاملThermal dependence of sprint performance of the lizard Sceloporus occidentalis.
Sprint velocity of the lizard Sceloporus occidentalis was maximal at preferred body temperature (Tb, 35 degrees C). Mean running velocity (VR) and stride frequency (f) at this temperature were 3.23 +/- 0.7 (mean +/- S.E.M.) ms-1 and 15.6 +/- 0.3 s-1, respectively. VR and f did not change significantly when Tb was raised to 40 degrees C. At Tb values between 25 and 35 degrees C the thermal depen...
متن کاملThermal dependence of passive electrical properties of lizard muscle fibres.
1. The thermal dependence of passive electrical properties was determined for twitch fibres from the white region of the iliofibularis (IF) muscle of Anolis cristatellus (15-35 degrees C) and Sceloporus occidentalis (15-40 degrees C), and for twitch fibres from the white (15-45 degrees C) and red (15-40 degrees C) regions of the IF of Dipsosaurus dorsalis. These species differ in thermal ecolog...
متن کاملThermal dependence of endurance and locomotory energetics in a lizard.
The thermal dependencies of endurance and the rates of oxygen cnsumption (VO2) and carbon dioxide production (VCO2) were determined for the lizard Dipsosaurus dorsalis walking on a treadmill. The thermal dependencies of endurance and maximal VO2 (VO2 max) are nerly identical. The maximal sustainable speed and the speed at which VO2 max is attained at each experimental body temperature are the s...
