SGER: Collaborative Research: Sleep in Nocturnal Bird Migrants, an Interdisciplinary Study

合作研究：夜间迁徙鸟类的睡眠，这是一项跨学科研究弗兰克·r·摩尔南密西西比大学动物一生要么醒着，要么睡着。清醒使动物能够有效地与环境互动，而清醒时的表现取决于睡眠，而睡眠的功能在很大程度上仍然未知。动物可能会通过单半脑睡眠来缓解睡眠和清醒之间的冲突，这是一种大脑半球睡觉而另一个半球保持清醒的独特状态。这个跨学科的合作项目利用夜间候鸟作为自然模型系统来研究睡眠的行为和生理特性，自然发生的睡眠缺失的后果，以及伴随睡眠缺失的补偿性调整。大多数鸟类在白天活动，晚上睡觉，除了迁徙期间，它们的迁徙飞行发生在晚上。通过夜间迁徙，候鸟减少了被捕食的威胁，改善了飞行的大气条件，白天有更多的时间觅食。抛开夜间迁徙的优势不谈，鸟类在夜间迁徙必然会失去睡眠，睡眠行为的改变可能会产生不良后果。对斯温森画眉鸟（一种洲际候鸟）的实验室和野外睡眠研究结合起来，探讨了季节性睡眠不足的鸟类是如何在行为和生理层面上弥补睡眠不足的。这项研究的贡献是根据方法论在睡眠研究中的应用和对睡眠功能的理解来衡量的。

Collaborative Research: Sleep in nocturnal bird migrants, an interdisciplinary study Frank R. MooreUniversity of Southern MississippiAnimals spend their lives either awake or asleep. Wakefulness allows animals to interact effectively with their environment, while waking performance is contingent on sleep, the function of which remains largely unknown. An animal may mitigate the conflict between sleep and wakefulness by engaging in unihemispheric sleep, a unique state during which one cerebral hemisphere sleeps while the other remains awake. This interdisciplinary, collaborative project takes advantage of nocturnal bird migrants as a natural model system to study the behavioral and physiological properties of sleep, the consequences of naturally occurring sleep loss, and the compensatory adjustments that accompany sleep loss. Most bird species are active during the day and sleep at night, exceQt during migration when their migratory flights occur at night. By traveling at night a migrating bird experiences reduced threat of predation, improved atmospheric conditions for flight, and more time to feed during the day. Advantages of nocturnal migration aside, birds necessarily lose sleep by migrating at night and changes in sleep behavior could have adverse consequences. Laboratory and field studies of sleep in the Swainson' s Thrush, an intercontinental bird migrant, are combined to ask how seasonally sleep deprived birds compensate for that deprivation at the behavioral and physiological level. The contribution of the study is measured in terms of both application of methodology to the study of sleep and understanding the function of sleep.
