Human activities can create noise pollution and there is increasing international concern about how this may impact wildlife. There is evidence that anthropogenic noise may have detrimental effects on behaviour and physiology in many species but there are few examples of experiments showing how fitness may be directly affected. Here we use a split-brood, counterbalanced, field experiment to investigate the effect of repeated boat-noise playback during early life on the development and survival of a marine invertebrate, the sea hare Stylocheilus striatus at Moorea Island (French Polynesia). We found that exposure to boat-noise playback, compared to ambient-noise playback, reduced successful development of embryos by 21% and additionally increased mortality of recently hatched larvae by 22%. Our work, on an understudied but ecologically and socio-economically important taxon, demonstrates that anthropogenic noise can affect individual fitness. Fitness costs early in life have a fundamental influence on population dynamics and resilience, with potential implications for community structure and function.
人类活动会产生噪音污染，国际社会越来越关注这可能如何影响野生动物。有证据表明，人为噪音可能对许多物种的行为和生理产生有害影响，但很少有实验实例表明其如何直接影响生物适应性。在此，我们进行了一项裂巢、平衡的野外实验，以研究在生命早期反复播放船只噪音对一种海洋无脊椎动物——法属波利尼西亚莫雷阿岛的条纹海兔Stylocheilus striatus的发育和生存的影响。我们发现，与播放环境噪音相比，播放船只噪音使胚胎的成功发育率降低了21%，并使刚孵化幼虫的死亡率额外增加了22%。我们对一个研究较少但在生态和社会经济方面很重要的分类群所做的研究表明，人为噪音会影响个体适应性。生命早期的适应性成本对种群动态和恢复力有根本性影响，可能会对群落结构和功能产生影响。
