This article discusses the processes that interact to cause extinction, and this discussion is then used to explain how the extinction process can be modeled. The authors emphasize recent attempts to provide quality control for PVA and the use of PVA models as a tool for making conservation decisions.en201310.1016/B978-0-12-384719-5.00173-884929963532
