Urbanization Effects on Nutrient Cycling and Soil: Extracellular Enzyme Function
Abstract
Anthropogenic activity has greatly altered ecosystem productivity and functioning through effects on regional and global climate changes (IPCC 2011). These changes, including increasing atmospheric CO2 concentrations ([CO2 ]) and temperatures, changes in precipitation patterns, and increased N deposition, can alter C, N, and P cycling in ecosystems by directly and indirectly affecting plant material entering the soil (O’Neill and Norby 1996, Norby 1998, Norby et al. 2001), and the rate at which this plant material is decomposed into dissolved organic matter and available nutrients. Further, changes associated with global change have been shown to accelerate decomposition processes and nutrient cycling (Vitousek et al. 1997, Rustad et al. 2001, Kelley et al. 2011).
