His current research examines interactions among cattle, management strategies, and precipitation.  His specific research questions are: At what scales (temporal and spatial) do forage resources mediate cattle foraging behavior and performance? What vegetation measurement tools can benefit adaptive rangeland management? What local and hemispherical meteorological factors can be incorporated into ranch decision-making to benefit year-to-year livestock performance?  **Publications** Augustine, D.J., Kearney, S.P., **Raynor, E.J.**, Porensky, L.M.andDerner, J.D.2023.Adaptive, multi-paddock, rotational grazing management alters foraging behavior and spatial grazing distribution of free-ranging cattle.*Agriculture, Ecosystems & Environment*352: 108521.https://doi.org/10.1016/j.agee.2023.108521 **Raynor, E.J.,**Derner, J.D., Augustine, D.J., Jablonski, K.E., Porensky, L.M., Ritten, J., Hoover, D.L. and Elliott, J. 2022.****Balancing ecosystem service outcomes at the ranch-scale in shortgrass steppe: The role of grazing management.*****Rangelands* 44: 391-397. ****https://doi.org/10.1016/j.rala.2022.05.003 **Raynor, E.J.**,Derner, J.D.,Porensky, L.M., Hoover, D.L., Augustine, D.J.,Jablonski, K.E.,Dwyer, A.M., andK.P.
