| Abstract/Contents: | "Urban land-use change (LUC) can affect soil characteristics and associated biogeochemical cycles through altered disturbance regimes, management practices (e.g., irrigation), built structures, and modified environments (e.g., heat island). As a result, the conversion of native to urban ecological systems should significantly affect the physical, chemical, and ecological characteristics of soil at multiple spatial and temporal scales. The net effect of urban LUC on soil characteristics and biogeochemical cycles will vary depending on the pre-existing ecosystem and the human response to characteristics of that ecosystem. For instance, development patterns and the need for infrastructure are strongly affected by local topography and site limitations (e.g., soil drainage), while human decisions, such as cultivating non-indigenous vegetation (e.g., turfgrass), results in management inputs driven by regional edaphic and climate conditions. Additionally, human preferences for urban vegetation are strongly related to cultural factors that typically show up at the scale of land ownership, or parcel scale. Therefore, the overall effect of urban LUC on soil characteristics should vary within an urban area and by ecoregion and also be coupled to land management, land cover, and cultural preferences. Based on these multiple scale effects we present a proposed study design, local to global in scale, to address two hypotheses: (1) At local and regional scales, anthropogenic (urban) factors overwhelm the effect of native soil forming factors such that the spatial pattern of soil chemical, physical and ecological characteristics will result from human activities, built environment, and deposition patterns and (2) When anthropogenic (urban) factors overwhelm native factors, the chemical, physical, and ecological characteristics of urban soils will at a global scale be more similar across metropolitan areas than the native soils typical of the region, i.e. the Ecosystem Convergence Hypothesis." |
