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比来自其他栖息地的个体具有更高的适应度时，就会发生局部适应。然而，导致这种情况的确切因素通常尚不清楚。通过利用淡水鱼黑条纹顶鲦鱼（Fundulus notatus）的湖泊和溪流种群，这项工作将增强我们对这两种栖息地的局部适应的理解，并加深我们对身体大小和形状如何反映局部适应的理解。它还将研究水流状况的变化对当代鱼类进化的影响，因为伊利诺伊州的许多河流已被蓄水以创建用于休闲钓鱼的湖泊。同样重要的是，这项工作将为几名大学本科生提供研究机会，并通过外展活动向公民介绍伊利诺伊州本土鱼类，从而使当地社区受益。
