We examine soil and vegetation dynamics involved
in arid land degradation and desertification at
multiple scales.

Phytochemistry plays a role in such vegetation
dynamics as allelopathy, herbivore deterrence,
and plant-plant competition. Our goals are to

• determine the volatile composition of JER plants
• define how these volatiles interact with key soil
  microbes, herbivores, and competitive plants
• identify areas where phytochemical interactions
  contribute to success or failure of a plant
  species.
• Apply findings to development of remediation
  strategies.
