Preservation of Species and Genetic Diversity
提出一种数学规划方法，在有限资源下最大化保护物种的多样性，将多样性定义为灭绝物种与其最近存活亲属间遗传距离之和的负值，并应用于15种鹤类和208个北美濒危鸟类属的保护。
This article presents a mathematical programming approach to determine a conservation strategy that maximizes preserved species' diversity under limited resource availability. Diversity is defined as the negative of total diversity loss given by the sum of genetic distances between extinct species and their closest surviving relatives. The model incorporates both species richness and genetic diversity as the conservation criteria when determining species preservation and site selection decisions. The article also presents two empirical applications to the conservation of 15 crane species and 208 genera including most of the endangered or threatened North American bird species.
