Spatially-Dependent Biotic And Abiotic Factors Drive Survivorship And Physical Structure Of Green Roof Vegetation, Jason Aloisio

Student Publications

Plant survivorship depends on biotic and abiotic factors that vary at local and regional scales. This survivorship, in turn, has cascading effects on community composition and the physical structure of vegetation. Survivorship of native plant species is variable among populations planted in environmentally stressful habitats like urban roofs, but the degree to which factors at different spatial scales affect survivorship in urban systems is not well understood. We evaluated the effects of biotic and abiotic factors on survivorship, composition and physical structure of two native perennial species assemblages, one characterized by a mixture of C₄ grasses and forbs (Hempstead …
