Rick Estell
Dr. Estell is Lead Scientist at the USDA Agricultural Research Service’s Jornada Experimental Range. His research emphasis is on the biochemical basis of diet selection and the influence of secondary chemicals on shrub consumption by ruminants. His focus recently shifted to understanding the production potential and ecological impacts of a little known cattle biotype-the Raramuri Criollo. He co-leads the Jornada Long Term Agroecosystem Research (LTAR) common experiment examining the behavior and attributes of this biotype.
