Abstract: 

**The objective of the present research was to determine whether there have been changes in the structure and function of the surface (0-20cm) soil system, the zone most affected by litter decomposition, which is associated with the rapid movement of mesquite from historical habitats (arroyo and playa fringe) into recent habitats (grassland and dunes).

We hypothesized that the soil biotic communities would be poorly developed in the recent mesquite habitats because of lower soil C and nutrient concentrations. As a result of these differences we predicted lower rates of net N mineralization in the soils from recent mesquite habitats. Data set contains analyses for gravimetric soil moisture, pH, phosphate, total Kjeldahl nitrogen, total phosphorus, NO3-N nitrogen mineralization, total inorganic nitrogen, NH4-N nitrogen mineralization, organic carbon, inorganic carbon, total roots, tap roots, intermediate roots, and fine roots.

Data set contains microarthropod code, order, family, total number of mites, and trophic group for microarthropods sampled at two depth ranges in the top 20 cm of soil.

Data set contains Baerman Funnel extracted nematodes (fungal feeders, bacterial feeders, omnivore-predator, total plant parasites, total nematodes) and Elutriator extracted nematodes (fungal feeders, bacterial feeders, omnivore-predator, total plant parasites, total nematodes).
