鸟类化学通信是一个迅速崛起的领域，但由于严重缺乏关于可交流生态相关信息的挥发性化学物质(信号化学物质)的信息，这一领域一直受到阻碍。鸟类嗅觉和化学交流的一种可能的功能是父母-胚胎和胚胎-胚胎的交流，但尚未被发现。父母和发育中的胚胎之间的交流可能起到调节父母行为的作用，而胚胎之间的交流可以控制孵化的同步性。胚胎发声和振动在发育后期被认为是一种交流手段，但在胚胎能够独立运动和发声之前的早期阶段，这是不可能的。在这里，我们展示了日本鹌鹑(Coturnix Japan Onica)卵子发育过程中释放出的挥发物传达了有关卵子受精性的信息，以及胚胎的性别和发育状况。具体地说，卵的挥发物在孵化过程中发生了变化，在受精卵和受精卵之间存在差异，并且早在孵化第一天就可以预测胚胎的性别。因此，鸡蛋气味有可能促进父母-胚胎和胚胎-胚胎的相互作用，因为它允许在通过其他方式进行评估之前很久就评估胚胎发育的关键指标。这也开启了一种有趣的可能性，即父母或许能够从鸡蛋挥发物中收集进一步的相关信息，如胚胎的健康、生存能力和遗传。通过测定鸡蛋中挥发性物质所传递的信息，我们希望能够促进对鸡蛋气味生态作用的进一步研究。
Avian chemical communication is a rapidly emerging field, but has been hampered by a critical lack of information on volatile chemicals that communicate ecologically relevant information (semiochemicals). A possible, but as yet unexplored, function of olfaction and chemical communication in birds is in parent-embryo and embryo-embryo communication. Communication between parents and developing embryos may act to mediate parental behaviour, while communication between embryos can control the synchronicity of hatching. Embryonic vocalisations and vibrations have been implicated as a means of communication during the later stages of development but in the early stages, before embryos are capable of independent movement and vocalisation, this is not possible. Here we show that volatiles emitted from developing eggs of Japanese quail (Coturnix japonica) convey information on egg fertility, along with the sex and developmental status of the embryo. Specifically, egg volatiles changed over the course of incubation, differed between fertile and infertile eggs, and were predictive of embryo sex as early as day 1 of incubation. Egg odours therefore have the potential to facilitate parent-embryo and embryo-embryo interactions by allowing the assessment of key measures of embryonic development long before this is possible through other modalities. It also opens up the intriguing possibility that parents may be able to glean further relevant information from egg volatiles, such as the health, viability and heritage of embryos. By determining information conveyed by egg-derived volatiles, we hope to stimulate further investigation into the ecological role of egg odours.
