Data for: Little parental response to anthropogenic noise in an urban songbird, but evidence for individual differences in sensitivity

Anthropogenic noise exposure has well-documented behavioral, physiological and fitness effects on organisms.  However, whether different noise regimes evoke distinct responses has rarely been investigated, despite implications for tailoring noise mitigation policies.  Urban animals might display low responsiveness to certain anthropogenic noise regimes, especially consistent noise (e.g. freeway noise), but might remain more sensitive to more diverse noise regimes.  Additionally, whether individuals differ in noise sensitivity is a rarely explored issue, which is important to fully understand organismal responses to noise.  To address these knowledge gaps, we used a field experiment to measure how urban great tits (Parus major) altered parental behaviors in response to two noise regimes: consistent freeway noise, and a diverse anthropogenic noise regime that incorporated variability in noise type and temporal occurrence.  We also evaluated whether sex, age, or a well-described personalit...

人为噪声暴露对生物体的行为、生理及适合度（fitness）影响已有充分的文献记录。然而，尽管不同噪声模式（noise regime）的研究对制定噪声缓解政策具有重要指导意义，但针对不同噪声模式是否会引发生物体产生差异化响应的相关研究却鲜有开展。城市动物对某些人为噪声模式，尤其是持续噪声（如高速公路噪声（freeway noise）），可能表现出较低的响应性，但对更多样化的噪声模式则可能保持更高的敏感性。此外，个体间的噪声敏感性是否存在差异也是一个鲜有探讨的问题，而该问题对于全面理解生物体对噪声的响应至关重要。为填补上述研究空白，我们通过野外实验探究了城市大山雀（Parus major）如何响应两种噪声模式并改变其育幼行为：一种为持续的高速公路噪声，另一种为涵盖噪声类型与时间分布变化的多样化人为噪声模式。我们还评估了性别、年龄以及一种已被充分描述的性格特征是否会影响个体的噪声敏感性……
