摘要: Recent efforts to conserve biodiversity below the species level have been guided by concept of Evolutionarily Significant Units (ESUs) – populations or groups that contribute substantially evolutionary legacy as a whole. A variety published frameworks for defining ESUs exist, but all focus on identifying lineages. Captive breeding programs endangered can present special challenges ESU evaluations, particularly when legal protection depends membership. An alternative framework focuses current ecological context rather than lineages provides novel way thinking about captive-wild systems.
