Conservation biology, said to be a "mission-oriented crisis discipline" (Soulé 1986), is a multidisciplinary science that has developed to address the loss of biological diversity. Conservation biology has two central goals: 1. to evaluate human impacts on biological diversity and 2. to develop practical approaches to prevent the extinction of species (Soulé 1986, Wilson 1992). The field seeks to integrate conservation policy with theories from the fields of ecology, demography, taxonomy, and genetics. The principles underlying each of these disciplines have direct implications for the management of species and ecosystems, captive breeding and reintroduction, genetic analyses, and habitat restoration.
