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.

当个体在其原生栖息地中具有比来自其他栖息地的个体更高的适应性时，发生局部适应。然而，导致这种情况的确切因素往往并不清楚。通过利用湖泊和溪流种群的淡水鱼类，黑条纹顶米诺鱼（底notatus），这项工作将提高我们的理解，当地适应这两个栖息地，并增加我们的了解如何身体的大小和形状可能反映当地的适应。它还将研究水流状态变化对鱼类当代进化的影响，因为许多伊利诺伊州的河流已被扣押，以创造休闲捕鱼的湖泊。同样重要的是，这项工作将有利于当地社区通过提供研究机会，为几个大学本科生和教育市民对本地伊利诺伊州鱼类通过外联活动。
