模拟分析了繁殖群体大小、繁殖偏倚和占群优势雄性数目对麋鹿的有效种群大小的影响。

We simulated the impacts of breeding herd size, reproductive skew and numbers of breeding stags on the inbreeding coefficient of Père David's deer.

当时的人数甚至不及现在濒临灭绝的黑猩猩（21000头）和大猩猩（25000头）的有效种群大小（即能生育的个体数量）。

That number is smaller than current figures for the effective population size (or number of breeding individuals) for endangered species such as chimpanzees (21, 000) and gorillas (25, 000).
