英文文献：The Ghost of Extinction: Preservation Values and Minimum Viable Population in Wildlife Models-灭绝的幽灵:野生动物模型中的保护价值和最低存活数量
英文文献作者：van Kooten, G. Cornelis,Eiswerth, Mark E.
英文文献摘要：
The inclusion of a minimum viable population in bioeconomic modeling creates at least two complications that are not resolved by using a modified logistic growth function. The first complication can be dealt with by choosing a different depensational growth function. The second complication relates to the inclusion of the in situ benefits of wildlife into the analysis. Knowledge about the magnitude of the in situ benefits provides no guide for policy about conservation management. Simply knowing that people are willing to pay a large amount each year to protect a species says nothing about whether one should manage habitat to protect or enhance the species' numbers, unless the species is in imminent danger of extinction. If willingness to pay is to be a guide, it needs to be better tied to population numbers, especially the minimum viable population.
在生物经济模型中包含最小可行种群至少会产生两种并发症，而使用改进的logistic生长函数无法解决这两种并发症。第一个并发症可以通过选择不同的depensational growth function来处理。第二个复杂的问题涉及到将野生动物的就地利益纳入分析。关于原地利益的重要性的知识并不能为保护管理政策提供指导。仅仅知道人们愿意每年支付一大笔钱来保护一个物种，并不能说明人们是否应该管理栖息地来保护或增加物种的数量，除非这个物种濒临灭绝。如果支付意愿是一种指导，它需要更好地与人口数量挂钩，特别是最低可存活人口。
