噪音环境下蛙类的通讯策略

Communication strategy of frogs in noisy environment

声音通讯对蛙类的生存和繁殖起着重要的作用。自然条件下,蛙类所生活的环境会存在环境噪音(生物噪音和非生物噪音),这些噪音可能会对蛙类的声音信号产生遮蔽,使得蛙类声音信号的发现和识别都变的更加困难。为了有效通讯,发声者必须发出显著有别于背景噪音的声音。通常,蛙类可以采用不同的策略来抵御噪音对声音传递的不利影响,并对噪音的干扰形成一定的适应机制,这种适应可以分为长期和短期适应两种,从适应的角度对噪音环境下蛙类的声音通讯策略进行总结,使得人们对蛙类如何适应噪音环境进行有效通讯有着更深入的理解。

Acoustic communication plays a vital roles regulating the survival and reproduction of frogs. There were many environment noises including abiotic and biotic noise in their habitat, which would mask their acoustical signal and make the signal detection and recognition more difficulty. For the communication to be effective, senders must emit signals that are conspicuous and distinct from oth- er background noise. Usually, frogs in noise habitat would use different strategies to avoid masking and evolved a certain adaptive mechanism to avoid masking by sounds in the ambience, which include long-term adaptation and short-term adaptation. The current ar- ticle will focus on the strategies of acoustical communication of frogs in noise ambient and the results will benefit to the understanding for readers how frogs adapt the noisy environment and communicate effectively.
