摘要。临时巢（露营），埃西顿burchelli（韦斯特伍德）的温度调节相当精确。尽管热带雨林中的环境温度在白天的变化范围为7摄氏度，但露营地中心的温度保持在28.5± 1摄氏度。露营地地幔之下的温度变化要比核心大得多。计算表明，当环境温度下降时，行军蚁在露营地的基础代谢率将产生它们保持温暖所需的所有热量。行军蚁可能通过打开巢穴内的通风通道来调节热量的损失。
ABSTRACT. The temporary nests (bivouacs), of Eciton burchelli (Westwood) thermoregulate with considerable precision. Temperatures at the core of the bivouac are maintained at 28.5±1d̀C even though ambient temperatures in their tropical rainforest home change during the day over a range of 7d̀C. Temperatures just under the mantle of the bivouac vary much more than at the core. Calculations suggest that the basal metabolic rate of the army ants in bivouac will generate all the heat that they need to keep warm when ambient temperatures drop. The army ants probably regulate heat loss by opening up ventilation channels within the nest.
