Data for: Noise can affect acoustic communication and subsequent spawning success in fish

In this study we tested the effect of continuous noise on courtship behaviour in two closely-related marine fishes: the two-spotted goby (Gobiusculus flavescens) and the painted goby (Pomatoschistus pictus) in aquarium experiments. Both species use visual and acoustic signals during courtship. In the two-spotted goby we used a repeated-measures design testing the same individuals in the noise and the control treatment, in alternating order. For the painted goby we allowed females to spawn, precluding a repeated-measures design, but permitting a test of the effect of noise on female spawning decisions. Males of both species reduced acoustic courtship, but only painted gobies also showed less visual courtship in the noise treatment compared to the control. Female painted gobies were less likely to spawn in the noise treatment.

本研究旨在探讨持续噪声对两种亲缘关系密切的海洋鱼类——双色鰓鰕鱼（Gobiusculus flavescens）和绘斑鰓鰕鱼（Pomatoschistus pictus）求偶行为的影响。两种物种在求偶过程中均利用视觉和听觉信号。在双色鰓鰕鱼的研究中，我们采用了重复测量设计，通过交替顺序对同一个体在噪声和对照组中进行测试。对于绘斑鰓鱼，我们允许雌性产卵，从而排除了重复测量设计，但允许对噪声对雌性产卵决策的影响进行测试。两种物种的雄性均减少了听觉求偶行为，而只有绘斑鰓鱼在噪声处理组中的视觉求偶行为相较于对照组有所减少。在噪声处理组中，绘斑鰓鱼的雌性产卵的可能性较低。 (N = 增加噪声处理组，S = 静音对照组)
