Doctoral Dissertation Improvement Grant: Comparative Fuel Use and Protein Conservation in Trans-Saharan Passerine Migrants

小行星9623836 每年春天，来自185个物种的约24亿只鸟类迁徙。 从非洲的越冬地来到古北界繁殖候鸟有185种，大多数是小型食虫雀形目。 长 距离 迁移 在 小 雀形 从生理学上讲，这是很有趣的，因为它结合了两种不同的生理状态：禁食和高有氧运动。 该项目将使用旧世界 莺（Sylviidae）为模式研究长距离春季迁徙雀形目鸟类的燃料利用和蛋白质保存。 短、中、长距离的候鸟（Sylvia spp）将在以色列Sede Boker的迁徙途中被捕获。 飞行所用燃料和蛋白质催化剂的变化将与能量储备和迁移距离的影响相关。 该项目有望增加对运动生理学，禁食生物学和迁移的新水平的理解 生理学 和 承诺 到 拓宽 我们对这些过程如何协同工作的理解。

9623836 Rubenstein Every spring approximately 2.4 billion birds from 185 species migrate from their African wintering grounds to breed in the Palaearctic. The migrants are members of 185 species and the majority are small insect eating passerines. Long distance migration in small passerines is physiologically intriguing because it combines elements from two disparate physiological states: fasting and high aerobic exercise. This project will use Old World warblers (Sylviidae) as a model to study the fuel use and protein conservation of long-distance vernal migrating passerines. Short, medium and long distance migrants (Sylvia spp) will be captured mid-migration in Sede Boker, Israel. Variation in fuels used in flight and protein catabolism will be correlated with the effects of energy reserves and migration distance. This project promises to add new levels of understanding to exercise physiology, fasting biology and migration physiology and promises to broaden our understanding of how these processes can work in concert.
