虽然喉形态往往反映出发声的适应性，但对发声行为特定方面的选择的结构后果仍然知之甚少。在这项研究中，我们研究了增加超声波呼叫在幼鼠对成年喉形态学的选择性繁殖的大鼠品系的影响。使用多种技术评估喉形态：在来自microCT扫描的3D模型中比较矿化软骨体积，使用透明和染色程序结合显微镜检查比较内部结构，使用组织学和显微镜检查比较细胞结构，并使用扫描能量色散X射线光谱评估元素组成。我们的研究结果表明，成年大鼠从线繁殖产生超声波通话率较高的幼崽有较短的声带和更矿化的甲状软骨相比，大鼠繁殖产生超声波通话率较低。声带长度的变化似乎可以解释这两种大鼠系中低频叫声的差异。我们认为，在高超声谱系中观察到的甲状软骨矿化的增加在超声呼叫产生期间提供了喉结构的增强。因此，我们的研究结果表明，喉形态的发声行为的选择效果，声学后果。为USV生产选择性饲养的大鼠在幼崽时显示出成年后喉形态的变化。
Although laryngeal morphology often reflects adaptations for vocalization, the structural consequences of selection for particular aspects of vocal behavior remain poorly understood. In this study, we investigated the effects of increased ultrasonic calling in pups on the adult larynx morphology in selectively bred rat lines. Laryngeal morphology was assessed using multiple techniques: mineralized cartilage volumes were compared in 3D‐models derived from microCT scans, internal structure was compared using clearing and staining procedures combined with microscopy, cellular structure was compared using histology and microscopy, and element composition was assessed with scanning energy dispersive X‐ray spectroscopy. Our results show that adult rats from lines bred to produce ultrasonic calls at higher rates as pups have shorter vocal folds and a more mineralized thyroid cartilage compared to rats bred to produce ultrasonic calls at lower rates. The change in vocal fold length appears to account for differences in low‐frequency calls in these two rat lines. We suggest that the observed increases in mineralization of the thyroid cartilage in the high‐ultrasound lineage provide increased reinforcement of the laryngeal structure during ultrasonic call production. Our findings therefore demonstrate an effect of selection for vocal behavior on laryngeal morphology, with acoustic consequences. Rats selectively bred for USV production as pups show changes in larynx morphology in adulthood.
