Presentation for the Symposium on BEER November 2023Towards a theory of host recovery dynamics followingdisease-induced declines: an epi-eco-evo perspectiveMark Wilber1, Joe DeMarchi1, Cherie Briggs2, Sabrina Streipert3,*1 Institute of Agriculture, University of Tennessee, Knoxville, TN 37996 2 Department of Ecology, University ofCalifornia, Santa Barbara, CA 93106 3 Department of Mathematics, University of Pittsburgh, Pittsburgh, PA 15260sas887@pitt.eduRecoveries of populations that have suffered severe disease-induced declines are being observed acrossdisparate taxa. Yet, we lack theoretical understanding of the drivers and dynamics of recovery in hostpopulations and communities impacted by infectious disease. We developed an epidemiological-ecological-evolutionary (E3) model to dissect the anatomy of host recovery trajectories following disease-induced de-clines and asked three questions: 1) how does host life history, pathogen life history, and initial variabilityin host defense affect population recovery trajectories? 2) how do recovery trajectories differ between hostpopulations evolving different defense strategies? and 3) how do community interacons alter recovery tra-jectories and reorganize communies following disease-induced declines? Simulations suggest that host lifehistory is a major driver of recovery trajectories, with faster hosts declining less and recovering more quicklythan slower hosts. Host defense strategy also affected trajectories, with hosts using resistance strategiesgenerally recovering more quickly than hosts using tolerance strategies. However, recovery dynamics werehighly dependent on community structure. By idenfying predictable characteristics of host recoveries, theE3 model provides a foundation to link observed patterns of host recovery to underlying processes.
