Ecology of heat-shock protein expression in honey bees: effects of age, behavior, and tissue heterothermia

蜜蜂热休克蛋白表达的生态学：年龄、行为和组织异质性的影响。内华达州拉斯维加斯大学的Elekonich和Stephen P. Roberts许多行为生活史转变通常只发生一次，并且在生物体进入新环境或改变生活史策略的成年阶段发生。这种转变在自然界中很常见，包括与年龄相关的从筑巢/蜂巢工作到觅食的社会昆虫，如蜜蜂。虽然关于热休克或应激蛋白（Hsps）表达的文献非常多，但其中一个未回答的问题是，在自然界中，Hsps在陆生动物的整个生命周期中表达的频率和程度。这项研究将为复杂的社会物种中年龄、基因表达和功能能力如何与行为（特别是觅食）相互作用提供重要的见解。它将提供一种行为的细胞成本的第一个措施，以及移动的陆地动物在其自然环境中一生中遇到的实际压力的第一个措施。该奖项将支持博士后研究人员的专业发展，以及一位新的女科学家在她职业生涯的早期阶段。

Ecology of heat-shock protein expression in honey bees: effects of age, behavior, and tissue heterothermiaMichelle M. Elekonich and Stephen P. RobertsUniversity of Nevada Las VegasMany behavioral life history transitions occur typically only once and during the adult stage of an organism as it moves into a new environment or changes a life history tactic. Such transitions are common in nature and include the age-related switch from nest/hive work to foraging in social insects such as the honey bee. Although the literature on expression of heat-shock or stress proteins (Hsps) is vast, one of the unanswered questions is how often and to what extent Hsps are expressed across the lifespan of a terrestrial animal in nature. The proposed research will provide important insight into how age, gene expression and functional capacity interact with behavior, particularly foraging, in a complex social species. It will provide the first measures of the cellular cost of a behavior and some of the first measures of actual stress encountered over the lifetime of a mobile terrestrial animal in its natural environment. This award will support the professional development of a postdoctoral researcher, and a new female scientist at the earliest stages of her career.
