Urbanization has reshaped the distribution of biodiversity on Earth, but we are only beginning to understand its effects ecological communities. While urbanization may have homogenization strong enough blur large-scale patterns in interaction networks, urban community still be associated with climate gradients reflecting biogeographical processes. Using 103 hummingbird-plant mutualistic networks across continental Americas, including 176 hummingbird and 1,180 plant species, asked how affects species interactions over large gradients. Urban were more generalized, exhibiting greater overlap. Higher generalization was also lower precipitation both natural areas, indicating that irrespective habitat type. habitats showed functional trait diversity over/underrepresentation specific clades. From side, communities had a higher prevalence nonnative nectar plants, which frequently visited by occurring areas. Therefore, affected through composition traits, as well floral resource availability. Taken together, show consistently modifies their interactions, plays role affecting structure these novel scale continents.
