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.  **Publications** Copeland, S.M.,**Hoover, D.L.,**Augustine, D.J.,****Bates, J.D., Boyd, C.S., Davies, K.W.,****Derner, J.D.,****Duniway, M.C.,****Porensky, L.M.****and Vermeire, L.T. 2023.Variable effects of long-term livestock grazing across the western United States suggest diverse approaches are needed to meet global change challenges.*Applied Vegetation Science*26(1):e12719.https://doi.org/10.1111/avsc.12719 Raynor, E.J., Derner, J.D., Augustine, D.J., Jablonski, K.E.,Porensky, L.M., Ritten, J.,**Hoover, D.L.** and Elliott, J. 2022.
