Effects of Horizontal and Vertical Island Biogeography on Green Roofs Arthropod Communities

What is it about?

This study explores the application of island biogeography theory to urban green roofs, focusing on the dual impact of vertical (building height) and horizontal (distance from open areas) components on arthropod communities. Our research, combines a comprehensive literature review with an extensive field study involving 18 rooftops and adjacent ground-level yards. We found significant differences in species richness and community composition between roofs and yards, and between the city core and edge, highlighting the critical role of green roofs in enhancing urban biodiversity. These findings offer valuable insights for urban ecology and green roof design, emphasizing the importance of spatial factors in promoting biodiversity in urban environments.
