ABSTRACT Evoked vocal responses of male frogs Batrachyla taeniata to synthetic advertisement calls and variants having different temporal features altered parametrically were studied to identify patterns of evoked vocal responses (EVRs) that conform with static and dynamic modes of variation and with corresponding selective processes affected by different temporal components of the acoustic signals. Frogs responded with higher call rates and longer call durations to stimuli of 25–100 pulses/s, resembling conspecific calls. This response mode was not related to spectral differences among stimuli, as frogs responded similarly to a series of stimuli built with noise instead of tones. Frogs responded with lower call rates and shorter call durations to a non-pulsed 500-ms tone having the duration of the complete call, a decrement related to the dissimilar spectral composition of the tone, restricted to a single frequency, as frogs responded strongly to a non-pulsed 500-ms stimulus built with noise instead of a 2.1-kHz sinusoidal. Frogs responded with lower call rates and shorter call durations to synthetic calls composed by 3 or less pulses. The EVRs for pulse rate stimuli series are consistent with a stabilizing selectivity pattern, whereas EVRs for pulse duration and call duration stimuli series conform with directional selectivity patterns.

来自南方温带森林 Batrachyla taeniata (Batrachylidae) 的青蛙诱发的声音反应的不同时间选择性模式

摘要研究了雄性青蛙 Batrachyla taeniata 对合成广告呼叫和具有参数改变的不同时间特征的变体的诱发声音反应，以识别符合静态和动态变化模式的诱发声音反应 (EVR) 模式以及受不同影响的相应选择过程。声信号的时间分量。青蛙以更高的呼叫率和更长的呼叫持续时间响应 25-100 脉冲/秒的刺激，类似于同种呼叫。这种响应模式与刺激之间的光谱差异无关，因为青蛙对一系列用噪音而不是音调构建的刺激做出类似的反应。青蛙以较低的呼叫率和较短的呼叫持续时间响应具有完整呼叫持续时间的非脉冲 500 毫秒音调，与音调的不同频谱成分相关的衰减，仅限于单一频率，因为青蛙对由噪声而非 2.1 kHz 正弦信号构建的非脉冲 500 毫秒刺激做出强烈反应。青蛙对由 3 个或更少脉冲组成的合成呼叫以较低的呼叫率和较短的呼叫持续时间作出响应。脉率刺激系列的 EVR 与稳定选择性模式一致，而脉冲持续时间和呼叫持续时间刺激系列的 EVR 符合定向选择性模式。
