摘要: Isotopic Tracer Reveals Depth-Specific Water Use Patterns Between Two Adjacent Native and Non-native Plant Communities by Clemence Pascale Warren, Master of Science Utah State University, 2011 Major Professor: Dr. Karen H. Beard Department: Wildland Resources plants have invaded over 100 millions acres western arid land in the US dramatically altered nutrient cycling rates. Changes water caused invasive species are particular interest because primary production Western is typically limited availability aquifer recharge reflects plant demand. Large-scale invasions can, therefore, be expected to cause large-scale changes hydrological cycles, but until recently, there been considerable limitations ability measure timing, location, extent use. Here we injected a tracer, deuterated (D2O), into five soil depths two sampling periods (May June) adjacent communities (native non-native dominated). Plants were sampled at several distances from tracer addition area determine horizontal vertical use native communities. The injection was coupled with measurements leaf level stomatal conductance, index, volumetric content estimate transpiration. We found that both
