Jonathan Ballou was the population manager and a research scientist at the Smithsonian Conservation Biology Institute in Washington, D.C. His research focused on the genetic and demographic problems confronted by small populations, especially of threatened species. He is recognized as a leader in developing the theoretical basis for the genetic management of small populations and in developing population management tools (software, applied theory) that are widely and internationally used by wildlife and zoo managers.
Ballou’s more recent activities have included co-authoring the text ‚Genetic Management
