Abstract

Green rooftops serve as potential habitats for organisms in urban environments. We studied patterns in ant species richness across eight green rooftops in Chicago and surrounding suburbs. We compared ant-sampling methods, ant species composition between rooftops and bases, and ant species richness between certain rooftop characteristics. On average pitfall traps captured significantly more ant species, and ant species on rooftops were a subset of the species around their bases. This study shows a green rooftop's potential as a habitat for ants in urban “concrete jungles,” providing us further reasoning to study rooftop communities as we continue to make cities green.
