I am studying the nitrogen fixation and diversity of the functional gene nifH of biotic crusts within the Reynolds Creek Watershed. To do this I am collecting surface samples of biotic crusts and performing DNA extractions, PCR amplification, and an acetylene reduction assay to understand the diversity and activity of the nitrogenase enzyme. My sites are located along the elelvational gradient which will allow me to examine the controls of temperature, moisture, and soil nutrients on nitrogen fixation.
