摘要

打哈欠是一种在脊椎动物中广泛观察到的刻板行为,是对环境的一种适应。之前的研究强调了打哈欠与生理唤醒或体温调节之间的相关性。然而,这些研究大多集中在吸热动物身上。到目前为止,在变温动物中打哈欠的功能仍不清楚。在这项研究中,我们观察了豹壁虎,Eublepharis macularius,一种变温爬行动物,在恒定的环境温度25°C, 30°C和35°C下的行为,为期3天。通过研究温度、自发打哈欠和活动水平之间的关系,我们发现打哈欠频率受到环境温度的影响,并且还观察到打哈欠后活动的显著增加,特别是在30°C和35°C的条件下。此外,在所有温度条件下,哈欠都有近24小时的周期性。这些结果与之前对吸热动物的研究一致,表明打哈欠的原始功能在脊椎动物物种中是守恒的。

Yawning and Its Temperature-Dependent Modulation in Leopard Geckos.

Yawning is a stereotyped behavior widely observed in vertebrates, serving as an adaptation to the environment. Previous research has highlighted the correlations between yawning and physiological arousal or temperature regulation. However, the majority of those studies have primarily focused on endothermic animals. Thus far, the function of yawning in ectothermic animals remains unclear. In this study, we observed the behavior of leopard geckos, Eublepharis macularius, ectothermic reptiles, over a period of 3 days under constant ambient temperatures of 25°C, 30°C, or 35°C. By investigating the relationship between temperature, spontaneous yawning, and activity levels, we found that yawning frequency is affected by ambient temperature, and also observed a significant increase in post-yawning activity particularly under the 30°C and 35°C conditions. Furthermore, a near 24-hour periodicity in yawning was detected under all temperature conditions. These results align with previous studies conducted on endothermic animals, suggesting the conservation of primitive functions of yawning across vertebrate species.

期刊介绍: Zoological Science is published by the Zoological Society of Japan and devoted to publication of original articles, reviews and editorials that cover the broad field of zoology. The journal was founded in 1984 as a result of the consolidation of Zoological Magazine (1888–1983) and Annotationes Zoologicae Japonenses (1897–1983), the former official journals of the Zoological Society of Japan. Each annual volume consists of six regular issues, one every two months.
