In this case, the species receives none of the benefits of a small sub-population (loss of the sub-population is not catastrophic to the species as a whole) and all of the disadvantages (inbreeding depression, loss of genetic diversity and increased vulnerability to environmental instability) and the population would survive better unfragmented.
在这种情况下，这种收到没有任何好处的一个小子-人口(损失分人口不是灾难性的物种作为一个整体)和所有缺点(近亲繁殖 的抑郁症，丧失 遗传多样性 和脆弱性增加对环境的不稳定性)和人口能够生存下去更好地完整的。
