The Use of Stable Isotopes in Ecophysiological Research

Jim Ehleringer
University of Utah

Research in stable isotopes is providing information on the ecophysiological responses of plant species to seasonal variations in precipitation. Such studies can also provide information on carbon dioxide respiration in soils and on the depths from which various plant species draw water. Details of these research efforts are available at
