John Wesley Powell, the great explorer of the American West, noted that if it was possible to spread all available surface water evenly across the western US, there would still be a desert very similar to the one he encountered on his journeys. Powell's insights were nearly prophetic. Since Powell's adventures, almost all of the great rivers in the American West have been dammed, diverted, or tapped for groundwater for the sake of agriculture and municipal water supplies. Nowhere are these changes more poignant and relevant than in Arizona. Dr. Sabo's research employs large-scale field experiments, stable isotopic tracers, and lab physiology to understand links between the water cycle and animal performance, abundance, and species diversity. Most of his work focuses on riparian and river ecology. For example, students in Dr. Sabo's lab study links between ground water aquifers and animals in riparian forests. Here we are finding that riparian trees connect groundwater to riparian animals that live above ground, and thereby alleviate water-stress for these organisms. Dr. Sabo also has projects that examine the effects of dams on energy flow through aquatic food webs. One aspect of this work is to understand how dams alter the relative dependence of top predators on aquatic and terrestrial sources of carbon, and thus energy. All of this work is geared towards understanding the sustainable management of water resources for humans and biodiversity. Dr. Sabo teaches classes in biometry, experimental design, field ecology, and water and sustainability.
