In an effort to study urban soil ecological systems, we have recently piloted the Global Urban Soil Ecology and Education Network (GLUSEEN). When fully implemented, GLUSEEN will be a distributed network that builds upon a worldwide set of decomposition experiments using nylon-mesh teabags sited in various urban soil habitat types. As an open and distributed experimental network focused on urban and exurban areas, GLUSEEN will have both scientific and public participatory advantages. Additionally, a matrix of urban soil habitat types based on anthropogenic disturbances and management regimes is presented. The matrix provides an experimental framework to address the Network's goal of comparing soil decomposition, biota, and characteristics across and within urban regions at multiple scales. Questions addressed include: (1) What is the relative importance of native vs. anthropogenic factors on soil characteristics? (2) How do assembly rules of soil communities differ in urban habitats, and how does this translate to ecological functions? (3) Do urban soil ecosystem attributes converge and soil communities homogenize at global and regional scales? (4) How can observations of ecological structure and function of urban soils by citizen scientists advance our understanding of soil ecology? As a proof of concept, we tested and demonstrated the practicality of nylon mesh teabags to measure decomposition between two soil habitat types exhibiting differences in soil abiotic and biotic factors over a 6-month period. Additionally, we illustrate the usefulness of the soil habitat matrix using published data that compared soil characteristics across five cities in four different habitat types.

Introduction To both study urban soil ecological systems and to ultimately engage citizen scientists, we have recently piloted a Global Urban Soil Ecology and Education Network (GLUSEEN), which when fully [...]
