In an effort to both engage citizen scientists and to study urban soil ecological systems, we have recently initiated a study as part of a Global Urban Soil Ecological Education Network (GLUSEEN), which when fully implemented will be a worldwide multi-city comparison investigating the effects of urban environmental changes on decomposition and soil community structure. GLUSEEN builds upon a worldwide set of decomposition experiments in which the substrate (litter) is kept constant in several habitat types associated with urban and urbanizing landscapes, similar to a global soil biodiversity experiment described in Wall et al. (2008). Moreover, at each location a native habitat type serves as a “reference” for the urban habitats. Experiments varies in their complexity and cost from very simple comparisons of a standard substrate and its weight loss over time to the chemical changes of the substrate as it decays, to the inclusion of measurements of the environmental and soil organism composition.
