Abstract

With the increasing spread of urbanization, Chicago's natural areas are dwindling. However, the land surrounding Chicago’s Metra rail system acts as an untouched pathway from the city's urban center to its surrounding suburban and then rural towns. Through this study, I examine and compare the effects of the urban to rural gradient on ant diversity through the use of the Metra rail tracks and unconnected residential sites. By recording ant species richness, both at stations and adjacent residential areas, I compare species’ ranges that have provided evidence for my hypothesis that urbanization negatively affects species richness in ants.
