摘要

人为噪音是世界生态系统中普遍存在的污染物,许多研究表明,噪音对不同分类群的生理、发育和行为都有负面影响。然而,研究倾向于孤立地关注人为噪声;许多物种经常经历这种污染物与其他人为和自然压力因素的结合。本研究通过野外实验研究了连续升高的感知捕食风险和暴露于道路噪音对矮猫鼬(Helogale parvula)警惕行为的综合影响。正如预期的那样,与近距离呼叫和环境声音(控制)回放相比,警报呼叫回放(模拟更大的捕食风险)和道路噪音回放分别导致了更高的警惕性。这两种压力源对总警觉性有相同的影响,为风险-干扰假说提供了支持。然而,与单独播放道路噪音相比,两种压力源的组合并没有产生显著不同的警觉性。因此,我们的实验提供了进一步的证据,证明人为噪音可以影响警惕-觅食之间的权衡,但当与捕食风险升高的自然压力源结合时,没有迹象表明存在加性或协同效应。如果我们要了解人为干扰对物种和群落的真正影响,进一步研究联合应激源效应是至关重要的。

The combined effects of elevated predation risk and anthropogenic noise on dwarf mongoose vigilance behaviour.

Anthropogenic noise is a pervasive pollutant in the world's ecosystems, with numerous studies demonstrating negative physiological, developmental and behavioural impacts across taxa. However, research has tended to focus on anthropogenic noise in isolation; many species often experience this pollutant in conjunction with other anthropogenic and natural stressors. Here, we used a field experiment to investigate the combined effects of a sequential elevation in perceived predation risk followed by exposure to road noise on the vigilance behaviour of dwarf mongooses (Helogale parvula). As expected, both alarm-call playback (simulating a greater predation risk) and road-noise playback independently led to more vigilance compared to close-call and ambient-sound (control) playbacks, respectively. The two stressors had an equivalent effect on total vigilance, lending support to the risk-disturbance hypothesis. The combination of the two stressors did not, however, generate a significantly different amount of vigilance compared to road-noise playback alone. Thus, our experiment provides further evidence that anthropogenic noise can influence the vigilance-foraging trade-off but no indication of an additive or synergistic effect when combined with the natural stressor of elevated predation risk. Further investigation of combined-stressor effects is critical if we are to understand the true impacts of anthropogenic disturbances on species and communities.

期刊介绍: Previously a supplement to Proceedings B, and launched as an independent journal in 2005, Biology Letters is a primarily online, peer-reviewed journal that publishes short, high-quality articles, reviews and opinion pieces from across the biological sciences. The scope of Biology Letters is vast - publishing high-quality research in any area of the biological sciences. However, we have particular strengths in the biology, evolution and ecology of whole organisms. We also publish in other areas of biology, such as molecular ecology and evolution, environmental science, and phylogenetics.
