Due to increases in airborne nitrogen pollution, excess nitrogen deposition has been affecting soil biogeochemical processes and plant community composition across the West. A number of studies have been conducted in forested systems and arid systems near urban centers; however, these investigations typically end with soil and plant tissue analysis. This study will build upon the work performed by Dr. Edith Allen at UC Riverside whose efforts revealed an atmospheric nitrogen deposition gradient from the San Bernardino Mountains through Joshua Tree National Park. I propose to bridge the gap between the effects of increased nitrogen on plants and harvester ants by examining stable isotope ratios in seeds and ants along the deposition gradient in the Mojave Desert. Harvester ant community response to seeds produced by plants along the gradient will then be investigated through ant nest density surveys and seed preference measurements.
