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.

蜜蜂热休克蛋白表达的生态学：年龄、行为和组织异温的影响内华达大学拉斯维加斯分校的米歇尔·m·埃莱科尼奇和斯蒂芬·p·罗伯茨许多行为生活史的转变通常只发生一次，而且发生在有机体进入新环境或改变生活史策略的成虫阶段。这种转变在自然界中很常见，包括蜜蜂等群居昆虫从巢/蜂巢工作到觅食的年龄相关转换。尽管关于热休克或应激蛋白（Hsps）表达的文献很多，但一个悬而未决的问题是，在自然界陆生动物的整个生命周期中，Hsps的表达频率和程度如何。这项拟议的研究将为了解年龄、基因表达和功能能力如何与复杂社会物种的行为，特别是觅食行为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衡量标准，以及移动的陆生动物在其自然环境中一生中所遇到的实际压力的一些第一个衡量标准。该奖项将支持一名博士后研究员的专业发展，以及一名处于职业生涯早期阶段的新女性科学家。
