How desertification affects nitrogen limitation of primary production on Chihuahuan Desert watersheds


Journal Article

It is hypothesized that the shift from perennial clump grasses to shrub dominated ecosystems in the Chihuahuan Desert has resulted in a change from predominantly water limited ecosystems to nitrogen-water limited ecosystems. In shrublands N and water are concentrated in patches under individual shrubs. This patchiness affects the temporal linkage between water inupts and N availability. Nitrogen and water availability are also affected by redistribution of organic water by wind, water and animals. Shifts from grassland to shrubland results in increased temporal and spatial variability of these essential resources for plant production. -from Authors
