This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Although the distribution of every species is limited to a particular range, the fundamental ecological processes that determine species' range boundaries are not understood well enough to predict how species will respond to environmental change. This project will investigate three overarching questions. First, what determines range limits? Second, how variable are range limits and what factors determine this variability? Third, how do range limits respond to environmental change? That is, how quickly do they respond and how predictable or variable are their responses given the inherent variability arising from random population processes? These questions will be addressed using a laboratory based experimental system together with mathematical and statistical modeling.Understanding what sets range limits and their variability is vital for understanding and forecasting how species will respond to climate change and to increasing variability in climate. This understanding is also vital for the management of species - both those that are undesirable and those that are endangered. Only a combination of manipulative experiments and mathematical modeling will yield the understanding needed by society over the available time before action is required. This approach has the additional benefit of providing real interdisciplinary training and experience for both graduate and undergraduate students, and plans are presented to include more than 40 undergraduate and 2 graduate students in the research. Both investigators have strong records of recruiting undergraduate assistants from groups typically underrepresented in biological research.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。 该项目将调查三个总体问题。 首先，什么决定范围限制？ 其次，范围限制的变量如何以及哪些因素决定了这种可变性？ 第三，范围限制如何响应环境变化？ 也就是说，鉴于随机人口过程产生的固有变异性，它们的响应速度有多快？它们的响应有多可预测或可变？ 这些问题将使用基于实验室的实验系统以及数学和统计建模来解决。理解设置范围限制及其可变性对于理解和预测物种如何应对气候变化以及对气候变化的增加至关重要。这种理解对于管理物种的管理也至关重要 - 既是不良的物种，又是濒危物种。只有操纵实验和数学建模的结合才能在需要采取行动之前提供社会所需的理解。这种方法具有更多的好处，即为研究生和本科生提供真正的跨学科培训和经验，并提出计划包括40多名本科生和2名研究生。两位研究人员都有很大的记录记录了从生物学研究中通常不足的群体招募本科助理的记录。
