人类活动会造成噪音污染，国际社会越来越关注这可能对野生动物造成的影响。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，但很少有实验表明健康可能受到直接影响。在这里，我们使用分巢、平衡、现场实验来研究生命早期重复播放船只噪音对海洋无脊椎动物--莫雷阿岛（法属波利尼西亚）的海兔Stylocheilus striatus的发育和生存的影响。我们发现，与环境噪音播放相比，暴露于船噪音播放会使胚胎的成功发育减少21%，并使最近孵化的幼虫的死亡率增加22%。我们的工作，一个研究不足，但生态和社会经济重要的类群，表明，人为噪声可以影响个人健身。生命早期的健身成本对人口动态和复原力具有根本性影响，并对社区结构和功能产生潜在影响。
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.
