Development of a SpatiallyRelated Phytochemical Database for a

Development of a Spatially-Related Phytochemical Database for a Chihuahuan Desert Shrubland 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: Ødetermine the volatile composition of JER plants Ødefine how these volatiles interact with key soil microbes, herbivores, and competitive plants Øidentify areas where phytochemical interactions contribute to success or failure of a plant species. ØApply findings to development of remediation strategies.
