AbstractThree experiments were conducted to examine how precipitation-vegetation ralationships for the shrubs Larrea tridentata, Prosopis glandulosa, and Flourensia cernua affect the interception, redistribution, and storage of water in desert ecosystem. The first experiment was designed to determine the percentage of rainfall partitioned as stemflow and throughfall, and also to evalute the effect of some plant conopy parameters on stemflow and throughfall. The second examined the effect of stem-angles on stemflow. The third assessed the effect of varying canopy areas and volumes as well as root allocation on redistribution of stemflow into the soil profile.... Analysis of rhodamine-B dye distribution under shrubs indicated that root channels are preferential pathways for movement of stemflow water into soil, and that this water is potentially the source of soil moisture which allows shrubs to persist and even prosper under drought conditions.
