The genus has been extensively used as a model for ecological, behavioral, and evolutionary investigations. We used auditory brainstem responses (ABRs), craniofacial morphology, and pinna measurements to compare characteristics that impact hearing in two wild-caught species, . We observed significant statistical differences in craniofacial and pinna attributes between species with overall exhibiting larger features than . ABR recordings indicated that both species showed similar best frequency thresholds between 8-24 kHz. We found significant effects of intensity on amplitude ratio of wave I and IV for , but not and effects of wave number on slope of the latency-intensity function with higher wave IV and shorter wave I slope of latency intensity function in . Finally, the data showed significant differences in latency shift of the DN1 component of the BIC in relation to ITD between species, while no significant differences were observed across relative DN1 amplitude. This study supports the used of and as future model species for auditory research.
该属已被广泛用作生态、行为和进化研究的模型。我们使用听觉脑干反应(ABR)、颅面形态和耳廓测量来比较影响两种野生捕获物种听力的特征。我们观察到物种之间颅面和耳廓属性存在显著的统计差异,总体上表现出比更大的特征。ABR记录表明,两个物种在8-24kHz之间显示出相似的最佳频率阈值。我们发现强度对的波I和波IV的振幅比有显著影响,但对没有影响,并且波数对潜伏期-强度函数的斜率有影响,在中波IV更高且波I潜伏期强度函数的斜率更短。最后,数据显示物种之间BIC的DN1成分相对于ITD的潜伏期偏移存在显著差异,而在相对DN1振幅方面未观察到显著差异。这项研究支持将和用作未来听觉研究的模型物种。
