Effects of Host Diversity on Infectious Disease
... At their simplest, infectious diseases involve only two species—a specialist pathogen and its sole host. The simplicity of these systems allows the development of ecological theory to understand the effects of variable host abundance, physiology, and behavior on pathogen transmission and disease dyn ...
