Microbial composition and functional diversity differ across urban green infrastructure types

In this study we investigated 1) whether engineered green roofs and bioswales in New York City had distinct microbial community composition and trait-associated diversity compared to non-engineered soils in parks and tree pits, and 2) if these patterns were consistent with divergent community assembly processes associated with engineered specifications of green infrastructure habitats not present in non-engineered tree pit and park lawn soils.
