Understanding water uptake and transport in trees is of great importance in arboriculture, especially in western North America where precipitation has historically been highly variable and much of the region has recently experienced extreme drought. The movement of water in the soil-plant-atmosphere continuum affects nutrient uptake and transport, photosynthesis, cell growth, and other most other plant processes; thus, water relations is intimately tied to all aspects of tree health. Further, because of the large volume of water they remove from the soil and release into the air, trees can affect the climate locally. Being able to limit the dieback and mortality of trees, like what was observed during the most recent major drought, by manipulating plant water status is going to be crucial for arboriculture in the 21st Century as the planet experiences rapid climate change.
Ed Bobich is a Professor of Biological Sciences at Cal Poly Pomona, where he has worked for the last sixteen years. He received his B.A. in Environmental, Population, and Organismic Biology from the University of Colorado at Boulder and his Ph.D. in Biology from the University of California, Los Angeles. Ed has also worked as a postdoc at Biosphere 2 Center and Whittier College. He has studied the anatomy, biomechanics, and physiological ecology of everything from prickly pears to rainforest trees and is currently focusing his research on the responses of desert perennials and native California trees to extreme drought.
