Local adaptation occurs when individuals have higher fitness in their native habitats compared to individuals from other habitats. Yet, often the exact factors leading to this are unclear. By utilizing lake and stream populations of a freshwater fish species, the blackstripe topminnow (Fundulus notatus), this work will enhance our understanding of local adaptation to these two habitats and add to our understanding of how body size and shape may reflect local adaptation. It will also examine the effects of changes in flow regime on contemporary evolution in fish, as many Illinois rivers have been impounded to create lakes for recreational fishing. Just as importantly, this work will benefit the local community through providing research opportunities for several college undergraduates and educating citizenry about native Illinois fishes through outreach events.

与其他栖息地的个体相比，当个人在本地栖息地中具有更高的适应性时，就会发生局部适应。但是，通常导致这一问题的确切因素尚不清楚。通过利用淡水鱼类的湖泊和流种群，黑条Topminnow（todulus notatus），这项工作将增强我们对当地适应这两个栖息地的理解，并增加我们对身体大小和形状的理解，以反映局部适应。它还将研究流动制度变化对鱼类当代进化的影响，因为许多伊利诺伊州河流都被扣押了为娱乐性捕鱼创建湖泊。同样重要的是，这项工作将通过为几个大学的大学生提供研究机会，并通过外展活动向当地人提供有关伊利诺伊州本地鱼类的公民的研究机会，从而使当地社区受益。
