US cities host more regionally unique species than previously thought

To better understand whether rapidly growing cities are hosting the same species, a team analyzed an immense volume of data gathered by citizen scientists during the four-day global City Nature Challenge. Study findings suggest that despite similarities across cities, urban biodiversity still strongly reflects the species that are native to a region. However, observations of shared ''cosmopolitan'' species like pigeons, white-tailed deer, and dandelions were more numerous than locally occurring species.
