Humans, particularly in cities, are noisy. Researchers are only just beginning to identify the implications of an increase in noise for species that communicate acoustically. In a recent paper, Slabbekoorn and Peet show, for the first time, that some birds can respond to anthropogenically elevated noise levels by altering the frequency structure of their songs. Cities are fruitful grounds for research on the evolution of animal communication systems, with broader implications for conservation in human-altered environments.
人类，尤其是城市中的人类，非常吵闹。研究人员刚刚开始认识到，噪音增加对那些通过声音进行交流的物种意味着什么。在最近的一篇论文中，斯拉贝克恩和皮特首次表明，一些鸟类可以通过改变它们歌声的频率结构来应对人为增加的噪音水平。城市是研究动物通讯系统进化的肥沃土壤，对人类改造环境中的保护具有更广泛的意义。
