【 摘 要 】

ABSTRACT Human activities change the acoustic environment in many settings around the world. These changes are complex, as different anthropogenic sound sources create different acoustic profiles; therefore, some sound sources may have greater impacts on wildlife than others. Animals may adapt to these altered acoustic environments by adjusting their vocalizations. In the case of bird song, this may be achieved by adjusting the whole song, which may preserve the spectral and temporal relationships between successive syllables, or by adjusting components (syllables) within the song. Determining which syllables are adjusted may help to elucidate the mechanisms, benefits, and limitations of song plasticity. We examined the effects of conventional industrial infrastructure used to extract shallow natural gas and petroleum (natural gas compressor stations, generator-powered oil well pumpjacks, power grid–powered oil well screw pumps, and generator-powered oil well screw pumps), compared with quiet control site...
