Abstract

Two kinkajous (Potos flavus, Procyonidae) showed marked nycthemeral variations in their rectal temperature. The mean Tr at night was 38.1 +/- 0.4 degrees C SD and 36.0 +/- 0.6 degrees C SD while resting during the day. Body temperature and O2-consumption were measured at ambient temperatures from 5-35 degrees C. With one exception at 35 degrees C, hypo- or hyperthermia was never observed. At air temperatures above 30 degrees C the bears reacted with behavioural responses. O2-consumption was minimal at Ta's from 23-30 degrees C. The mean basal metabolic rate was 0.316 ml O2 g-1 h-1 which is only 65% of the expected value according to the Kleiber formula. Below 23 degrees C heat production followed the equation : y (ml O2 g-1 h-1) = 0.727--0.018 Ta. The minimal thermal conductance was 90% of the predicted value according to the formula : C (ml O2 g-1 h-1 degrees C-1) = 1.02 W-0.505 (HERREID & KESSEL, 1967). Kinkajous are another distinct exception to the mouse to elephant curve.

摘要

两只蜜熊（黄喉蜜熊，浣熊科）的直肠温度呈现出明显的昼夜变化。夜间平均直肠温度为38.1±0.4℃（标准差），白天休息时为36.0±0.6℃（标准差）。在5至35℃的环境温度下测量了体温和耗氧量。除了在35℃时有一个例外情况外，从未观察到体温过低或过高的情况。在气温高于30℃时，蜜熊会有行为反应。在23至30℃的环境温度下，耗氧量最低。平均基础代谢率为0.316毫升氧气·克⁻¹·小时⁻¹，这仅为根据克莱伯公式预期值的65%。在23℃以下，产热遵循以下方程：y（毫升氧气·克⁻¹·小时⁻¹）= 0.727 - 0.018Ta。根据公式：C（毫升氧气·克⁻¹·小时⁻¹·℃⁻¹）= 1.02W⁻⁰.⁵⁰⁵（赫雷德和凯塞尔，1967年），最小热导率为预测值的90%。蜜熊是从小鼠到大象曲线的另一个明显例外。
