Abstract
The mean TB of G. coeruleus in each condition was positively correlated to the length of reinforcement, whereas the shuttle rate was inversely correlated to the length of reinforcement. The precision of TB regulation and the total metabolic expenditures of lizards did not vary significantly for different reinforcement regimes at the same ambient temperature. Eurythermality in G. coeruleus is caused by variations in preferred body temperature and not by fluctuations in TB around the particular regime body temperature.
摘要
在每种条件下，蓝斑鬣蜥的平均体温与强化时长呈正相关，而穿梭速率与强化时长呈负相关。在相同环境温度下，不同强化方案的蓝斑鬣蜥体温调节精度和总代谢消耗并无显著差异。蓝斑鬣蜥的广温性是由偏好体温的变化引起的，而非围绕特定调节体温的体温波动所致。
