Abstract

In order to determine where the characteristic temperature-dependent changes in calling rate, call duration and fundamental frequency of the call of the fire-bellied toad originate, I heated the head and other parts of the body to various temperatures. The greatest increase in calling rate occured when the head was heated; it varied with the amount of heating. The changes in calling rate and call duration brought about by heating were equally rapid, whereas the frequency of the call increased more slowly. This suggests that both calling rate and call duration change as a direct result of the effect of heat upon the nervous system.

摘要

为了确定铃蟾鸣叫速率、鸣叫时长和鸣叫基频随温度变化的特征源自何处,我将铃蟾的头部和身体其他部位加热到不同温度。当加热头部时,鸣叫速率增加最为显著;其随加热量而变化。加热引起的鸣叫速率和鸣叫时长的变化同样迅速,而鸣叫频率增加得较慢。这表明鸣叫速率和鸣叫时长的变化都是热量作用于神经系统的直接结果。
