Examining how urbanization induces changes in invasive toad populations

Biodiversity is increasingly diminished by humanity's many impacts, one major aspect of which is urbanization. Although there are a lot of studies reporting that urbanization influences wildlife population sizes and distributions, we are only beginning to study urbanization as an evolutionary force. Urban environments are also hotspots for invasive species, which can cause significant economic and ecological damage. In addition, invasive species provide an evolutionary laboratory in which we can study the effects of urbanization.
