亮点雄性豚鼠进行精心设计的求爱，包括发声(咕噜声)。我们研究了咕噜声的声学结构是否编码身份或社会地位。咕噜声编码个性，但不编码雄性支配地位。雄性质量可能编码在视觉和化学信号中。繁殖涉及交流。雄性通常会进化出精心制作的展示，使用来自不同模式的信号，宣布自己的品质，并吸引雌性交配。雌性可能会使用在求爱信号中编码的暗示来评估雄性，并就它们的素质做出选择。我们研究了小型鱼子酱啮齿类动物豚鼠的精致展示的声学元素。我们通过声学结构和男性声音表现的变化，验证了求爱呼唤(PURR)反映男性身份和社会地位的潜力。我们的结果表明，咕噜声编码的是个性，而不是男性的优势地位。不同个体的发声性能和咕噜声的结构参数不同，但声学参数与雄性优势地位之间没有相关性。在洞穴中求爱是一种多模式的展示，雄性的品质可能编码在视觉和化学信号中。这项研究是咕噜声中个性的第一个证据。进一步的研究可能会揭示每个交流渠道在鱼儿求偶过程中的作用。
HighlightsMale guinea pigs perform an elaborate courtship, including a vocalization (purr).We examined whether purr acoustic structure encodes identity or social status.Purr encodes individuality, but not male dominance status.Male quality may be encoded in visual and chemical signals.Reproduction involves communication. Males usually evolve elaborate displays that may declare their qualities and attract females to mate, using signals from different modalities. Females may use cues encoded in courtship signals to evaluate males and make choices concerning their qualities. We investigated the acoustic element of the elaborate display of the small Cavia rodents, the guinea pigs, Cavia porcellus. We verified the potentiality of the courtship call (purr) to reflect male identity and social status, through variations in acoustic structure and male vocal performance. Our results suggest that the purr encodes individuality but not male dominance status. Vocal performance and purr's structural parameters differed between individuals, but there was no correlation between acoustic parameters and male dominance status. Courtship in cavies is a multimodal display, and male quality may be encoded in visual and chemical signals. This study is the first evidence of individuality in the purr. Further studies may reveal the role of each communication channel in the courting process of Cavia.
