Understanding the extent of heterogeneity in soil microbial community structure and function at different scales within vegetation communities is critical to designing appropriate sampling protocols. Environmental factors (e.g. disturbance) make sampling in the riparian zone particularly challenging as vegetation communities are highly heterogeneous. To assess whether heterogeneity in soil and vegetation factors is reflected in microbial communities, a study was conducted in a riparian area in southern Australia. Nine quadrats were established encompassing different environmental conditions. Within quadrats physical, chemical and biological soil properties were analysed at two depths (top-so..View full abstract
