Spatial Phytochemical Database for Chihuahuan Desert Shrubland

This study explores soil and vegetation dynamics in arid land degradation, focusing on phytochemical interactions. Goals include identifying volatile composition of JER plants, studying interaction with soil microbes, herbivores, and competitive plants, and applying findings to develop remediation strategies. The research utilizes GCMS-TIC analysis of essential oil from Dalea scoparia, aiming to avoid recreating MS software and using CDF files more universally. The project involves the creation of a PhytoChemistry Database for LTER plant species, listing protocols, primary keys, plant species codes, related dataset IDs, GPS coordinates, essential oil projects, chemical marker gene sequences (TBA), and datasets.

  1. Development of a Spatially-Related Phytochemical Database for a Chihuahuan Desert ShrublandMary E. Lucero1, Rick Estell1, Ken Ramsey2, Kris Havstad11USDA-ARS Jornada Experimental Range, Las Cruces New Mexico (http://jornada-www.nmsu.edu/)2Jornada Basin LTER, New Mexico State University, Las Cruces, NM (http://jornada-www.nmsu.edu/) We examinesoil and vegetation dynamics involved in arid land degradation and desertification at multiple scales.

  2. 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.

  3. GCMS-TIC of essential oil from Dalea scoparia • Image (*.gif) or ASCII? • We want to avoid re-creating MS software • *.CDF files not as universal as we would like PhytoChemistry Database LTER plant species list Protocols Primary Key ID Plant species code Related Dataset ID’s (examples:Oil yield,DMA, GCMS, GCFID) X, Y, Z GPS coordinates and related details Essential Oil Projects Chemicals marker gene sequences (TBA) Datasets
