Dr. David Hoover’s current research is focused on how land management and climatic variability influence the ecohydrology of semi-arid rangelands. He examines carbon and water dynamics through the soil-plant-atmosphere continuum at multiple temporal and spatial scales, ranging from plant-level ecophysiology through ecosystem-level exchange, to landscape-level patterns of water movement, storage and use. In addition to his research, Dr. Hoover seeks to provide science-based information for land managers to facilitate sustainable livestock production in a changing climate.
