Using Integrative Bayesian Approaches to Examine Ecological and Evolutionary Influences on Disease Dynamics


Emerging infectious diseases threaten human health, food security, and global biodiversity. Disease ecologists have used theoretical models \(e.g., susceptible, infected, recovered \[SIR\] models\; individual based models\) to understand and predict pathogen spread and disease dynamics. Despite the important theory generated by such models, they are often not practical for guiding disease management because they require large amounts of data to parameterize. To obtain parameter estimates for disease models, ecologists have relied on markrecapture models, which require marking and tracking individuals over time. However, tracking animals can be difficult and logistically infeasible, especially for cryptic/secretive organisms or in small populations. Advanced statistical methods that provide similar inferences as markrecapture models for unmarked host populations \(e.g., populations where individuals are not individually tracked over time\) are critically needed to understand disease dynamics, assess pathogen impacts on populations, and develop pathogen mitigation strategies. In this seminar, we will be exploring quantitative advances that have allowed disease ecologists to gain a better understanding of the ecological and evolutionary mechanisms shaping host populations.
