在低适合度(高遗传负荷)的种群或物种中，人们提倡一种新的管理策略，称为遗传拯救，以帮助避免灭绝。在这个策略中，来自另一个种群的无关个体被引入到低适应度的种群中，以努力减少遗传负荷。在这里，我们提出了10个准则，可以用来评估何时基因拯救是一个好的管理选择，基因拯救计划和管理的适当程序，以及基因拯救的潜在负面遗传后果。这些指南随后被用来评估墨西哥狼和佛罗里达州美洲豹恢复计划的遗传救援方面。
In populations or species with low fitness (high genetic load), a new management strategy called genetic rescue has been advocated to help avoid extinction. In this strategy, unrelated individuals from another population are introduced into the population with low fitness in an effort to reduce genetic load. Here we present ten guidelines that can be used to evaluate when genetic rescue is a good management option, the appropriate procedures for genetic rescue planning and management, and the potential negative genetic consequences of genetic rescue. These guidelines are then used to evaluate the genetic rescue aspects of the recovery programs for the Mexican wolf and the Florida panther.
