This project will continue a quarter century of investigations that have used checkerspot butterflies as a model system to understand the ecology, genetics, and evolution of insects. The work has already led to numerous findings that are important to the design of rational pest control strategies. During this grant period, research will concentrate on four general questions. First, how does the behavior of adult butterflies influence the evolution of their populations? Second, how does climate influence the size of the butterfly populations? Third, how do butterflies colonize "empty" areas of habitat and how likely are newly established populations to go extinct? Fourth, how do populations in different places become genetically distinct? All of these are both theoretically important and also relevant to economic questions.

该项目将继续进行四分之一世纪的调查，这些调查已使用Checterspot蝴蝶作为模型系统，以了解昆虫的生态学，遗传学和进化。 这项工作已经导致了许多对理性害虫控制策略设计很重要的发现。 在此赠款期间，研究将集中在四个一般问题上。 首先，成年蝴蝶的行为如何影响人群的演变？ 其次，气候如何影响蝴蝶种群的大小？ 第三，蝴蝶如何定居“空的”栖息地区域，以及新建立的人群灭绝的可能性？ 第四，在不同地方的种群如何在遗传上截然不同？ 所有这些在理论上都很重要，也与经济问题有关。
