研究了两个实验组（1）在150、200、250、30 ℃ 5种不同温度下驯化的褐孔菌（Sceloporus olivaceus）的摄食（C）、排泄（FU）、同化（A）、呼吸（R）和生产（P）的能值和能值。（2）在不同季节分别采集环境温度分别为150 ℃，20 ℃，250和30 ℃。C、FU、A、R和P的体重比率和能量当量受温度的影响显著，总体上与体重呈负指数关系。虽然没有显着差异，在R之间的d d和非妊娠9 - 9，妊娠9 - 9的利率是17.4%。对C、FU、A、R和P的特定体重率进行了调整，以适应季节性环境温度、体温、天气条件和蜥蜴在一年中活动的小时数的代谢补偿模式，并用于计算一只典型的16.49克、1岁蜥蜴的年能量预算：C = 262.3 kcal（1，098 kJ），FU = 43.3 kcal（181.2 kJ），A = 218.0 kcal（912.5 kJ），R = 98.5 kcal（412.3 kJ），P = 119.5 kcal（500.2 kJ）。还通过假设活动蜥蜴的速率是其实验室代谢速率的2、2.5和3倍来计算R和P之间的A的年估计值。
Rates and energy equivalents of consumption (C), egestion + excretion (FU), assimilation (A), respiration (R) and production (P) were measured in two groups of Sceloporus olivaceus: (1) a laboratory group acclimated at five seasonally encountered temperatures (150, 200, 250, 30? and 350C); and (2) four acclimatization groups collected at different seasons when ambient temperatures corresponded to 150, 20?, 250 and 30'C. Weight-specific rates and energy equivalents of C, FU, A, R and P were significantly influenced by temperature, and in general, showed inverse exponential relationships with body weight. Although there were no significant differences in R between d d and nongravid 9 9, gravid 9 9 had rates that were 17.4% higher. Weight-specific rates of C, FU, A, R, and P were adjusted for patterns of metabolic compensation to seasonally encountered ambient temperatures, body temperatures, weather conditions, and number of hours lizards were active during the year, and were used to calculate the annual energy budget of a typical 16.49-g, 1-yr-old lizard: C = 262.3 kcal (1,098 kJ), FU = 43.3 kcal (181.2 kJ), A = 218.0 kcal (912.5 kJ), R = 98.5 kcal (412.3 kJ), and P = 119.5 kcal (500.2 kJ). The annual appor- tionment of A between R and P was also calculated by assuming that rates of active lizards are 2, 2.5 and 3X their laboratory metabolic rates.
