Urbanization alters the environment in profound ways that affects both the ecology and evolution of species and their interactions with one another. My thesis explores how urbanization alters ecological processes in urban populations and communities and investigates how patterns of ecological change feedback to influence the evolution of populations. Throughout my thesis, I use a combination of perspective pieces, literature reviews, and empirical research to identify and test avenues of research in the field of urban evolutionary ecology. In my first chapter, I reviewed the literature and identified key questions that needed to be addressed by the field. I followed up on one of these questions in my second chapter, where I reviewed the literature to identify patterns on non-adaptive evolution in urban populations. In the next two chapters, I measured the effects of urbanization on plant-pollinator and plant-herbivore interactions. My results demonstrated that urbanization alters interactions between Brassica rapa and its pollinators, leading to altered patterns of pollen dispersal and reproductive success in cities. Similarly, my results demonstrated that even small human settlements lead to increased seed predation rates and modified natural selection in Tribulus cistoides. My sixth chapter looked at the effects of urbanization on the mating system and population genetic variation of Impatiens capensis, and found that despite high outcrossing, urban populations were less genetically diverse than rural populations. My last chapter broadens the scope of my research and identifies joint effects latitude and sexual system on resistance to herbivory in Sagittaria latifolia. My thesis identified consistent effects of urbanization on the ecology and evolution of species and their interactions with one another and provides research directives to develop and broaden the scope of the field of urban evolutionary ecology.
