How house finches helped change our view of killer diseases: PLOS Biology: Parallel Patterns of Increased Virulence in a Recently Emerged Wildlife Pathogen. The upshot being that the “deadly-ness” or virulence of a disease was shown by the evidence of this deadly epidemic in house finches to be related to their population densities, the more densely populated, the stronger the virulence. Which makes sense in an ecological balance way as well, as many pathogens and parasites help control the numbers of many animal and plant populations, keeping them in check when larger scale factors such as food and shelter are encouraging a population to boom.
