Abstract
The spadix of Symplocarpus foetidus L. maintains an internal temperature 15 degrees to 35 degrees C above ambient air temperatures of -15 degrees to +15 degrees C. For at least 14 days it consumes oxygen at a rate comparable to that of homeothermic animals of equivalent size. Temperature regulation is accomplished by variations in respiratory rate.
摘要
臭菘的肉穗花序在环境空气温度为-15℃至+15℃时，能保持比其高15℃至35℃的内部温度。在至少14天的时间里，它消耗氧气的速率与同等大小的恒温动物相当。温度调节是通过呼吸速率的变化来实现的。
