Walter G WhitfordProfessor Walter G. Whitford received his PhD from the University of Rhode Island in Physiolgical-Ecology. He spent the next fifty years working in the Chihuahuan Desert as a faculty member in Biology at New Mexico State University (NMSU) where he wa principal investigator in the Desert Biome Program which was part of the International Biological Program. His research focused on field experiments and studies of termites and seed harvesting ants. That program stimulated his commitment to the importance of soil in arid ecosystems and the organisms that are involved in nutrient cycling. He also served as the first principal investigator for the Jornada Long Term Ecological Research Program. As principal investigator, he published more than 150 papers in peer reviewed journals dealing with most aspects of desert ecology. In 1993, he left the university to work as a senior research ecologist with the U. S. Environmental Protection Agency with a focus on monitoring and assessing the health of arid ecosystems. After retiring from the EPA he produced the first edition of Ecology of Desert Systems and continued to teach and do research in the Chihuahuan Desert. While a professor, he did research in Israel and Australia, evaluated arid lands research programs in South Africa, and organized a symposium on the Atacama and long-term ecological research in Chile. Before embarking on the 2nd edition of Ecology of Desert Systems, he was author or co-author of more than 300 peer-reviewed publications. Read More Read Less
