**We addressed the question, are microarthropod assemblages present in soils throughout the rhizosphere of a deep-rooted desert plant? If microarthropods are present, what is the taxonomic and functional structure of that assemblage?
The presence of a generalist microarthropod assemblage would suggest functional relationships among deep soil biota similar to the relationships documented in shallow soils. Data set consists of microarthropods and microarthropod numbers found at different soil depths associated with four mesquite ecosystems (playa, coppice dune, arroyo, and grassland).
