Host heterogeneity increases pathogen virulence in metapopulations

Heterogeneity is ubiquitous in real-world host populations, yet most theories assume homogeneity. Using a metapopulation model, we examine how host heterogeneities, such as uneven movement patterns and local productivities, affect the evolution of pathogen virulence.
