雄性求偶声信号从五个马拉维湖慈鲷鱼种的Pseudotropheus斑马复杂的记录和比较。来自Nkhata湾的P.zebra、Pseudotropheus callainos和未描述的物种Pseudotropheus 'zebra gold'以及来自Mphanga Rocks的Pseudotropheus emmiltos和Pseudotropheus faizilberi的雄性发出的声音在脉冲数量和脉冲周期方面存在显著差异。声学变量中的最大差异被发现的同域Mphanga岩石物种，在其他三个物种相比，男性的颜色和图案的差异相对较小。这些研究结果表明，种间配偶识别是由多模式信号介导的，不同的感觉通道的质量在同域物种群体之间存在差异。本研究还表明，声音峰值频率与男性的大小显着负相关，声音产生率显着增加求偶率。(c)2008年《作者杂志》汇编（c）2008年不列颠群岛渔业协会。
Male courtship acoustic signals from five Lake Malawi cichlid fish species of the Pseudotropheus zebra complex were recorded and compared. Sounds made by males of P. zebra, Pseudotropheus callainos and the undescribed species known as Pseudotropheus 'zebra gold' from Nkhata Bay, and Pseudotropheus emmiltos and Pseudotropheus faizilberi from Mphanga Rocks, differed significantly in the number of pulses and in pulse period. The largest differences in acoustic variables were found among the sympatric Mphanga Rocks species that, in contrast to the other three species, show relatively minor differences in male colour and pattern. These findings suggest that interspecific mate recognition is mediated by multimodal signals and that the mass of different sensory channels varies among sympatric species groups. This study also showed that sound peak frequency was significantly negatively correlated with male size and that sound production rate increased significantly with courtship rate.
