This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Economists study negotiation as a series of events, including partner choice, information gathering, and haggling. The context in which these negotiations occur--the market--is critical because individuals can adjust their demands in response to those of other players. Animals are faced with similar decisions during reproduction: who to court, how to approach a potential partner, at what level to display compared to competitors and when to give up unsuccessful interactions. Thus, economic models of negotiation in a market provide a framework in which courtship can be viewed as a process in which males and females use a series of tactics to improve their success. This project uses greater sage-grouse (Centrocercus urophasianus) as a model species to examine the importance of tactics used by males during courtship. A combination of experiments and detailed observations will be used, including robotic females to serve as experimental stimuli, multiple microphones and video cameras to record male signals and breeding behaviors. This approach will allow for the experimental study of courtship interactions in a wild population. Using this framework, the investigators expect to show that success in courtship, as in business, requires an attractive offer as well as skilled negotiation. Sage-grouse are currently being considered for federal listing as an endangered species. This project involves collaboration with an environmental education specialist to conduct extensive outreach addressing the role of basic and applied science in management decisions. This work will also compliment the ongoing applied research by the investigator to address how noise pollution may disrupt sage-grouse courtship negotiations and contribute to their population declines. This project involves mentorship and salary for a postdoctoral scholar and graduate students, and mentorship for dozens of undergraduates, many from underrepresented minorities.

该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。经济学家将谈判研究为一系列事件，包括选择合作伙伴、收集信息和讨价还价。这些谈判发生的环境--市场--至关重要，因为个人可以根据其他参与者的要求调整自己的要求。动物在繁殖过程中面临着类似的决定：向谁示好，如何接近潜在的伴侣，与竞争对手相比，在什么水平上展示，以及何时放弃不成功的互动。因此，市场中的谈判经济模型提供了一个框架，在这个框架中，求爱可以被视为一个过程，在这个过程中，男性和女性使用一系列策略来提高他们的成功。这个项目使用更大的鼠尾松鸡(Centrocercus Urophasianus)作为模式物种来研究雄性在求偶过程中使用的策略的重要性。将使用实验和详细观察相结合的方式，包括作为实验刺激的机器人雌性，记录雄性信号和繁殖行为的多个麦克风和摄像机。这种方法将允许对野生种群中的求偶互动进行实验研究。使用这一框架，调查人员希望表明，求爱的成功，就像在商业中一样，需要有吸引力的出价和熟练的谈判。鼠尾松鸡目前正被联邦政府列为濒危物种。该项目涉及与一名环境教育专家合作，开展广泛的外联活动，探讨基础科学和应用科学在管理决策中的作用。这项工作还将补充调查者正在进行的应用研究，以解决噪音污染如何扰乱鼠尾松鸡的求偶谈判，并导致它们的种群数量下降。该项目涉及对一名博士后学者和研究生的指导和工资，以及对数十名本科生的指导，其中许多人来自代表不足的少数族裔。
