Abstract Urbanization exerts many pressures on species, yet little is known about how these impact species interactions. Studies of urban plant-pollinator systems provide mounting evidence that urbanization impairs pollinator movement in fragmented landscapes, the consequences for pollinator-mediated plant reproduction remains unclear. In non-urban areas, habitat corridors can facilitate organisms including pollinators, but whether interactions areas understudied. To examine environments and green influence interactions, we measured reproductive success native common milkweed ( Asclepias syriaca ), community structure its two years along urban-rural transects Greater Toronto Area, Canada, one which followed a corridor. We found decreased male fitness (i.e., pollen removal), increased fruit set mean no. follicles per inflorescence), inconsistently affected female follicles) A. . simultaneously abundance richness. Proximity to corridor effort inflorescences) , while diversity richness was lower corridors. Notably, there were no consistent relationships between both presence, absence, These results demonstrate complexity with urbanization, corridors, communities shape investment populations.
