Population effective
WebThe effective population size (Ne), or the reproducing part of a population is often lower than the actual population size in small populations. The Ne of a population is closest in size to the generation that had the smallest Ne. This is because alleles lost in generations of low populations are not regained when the population size increases.

Harmon and Stanton Braude Introduction and Background Population size is extremely important in evaluating conservation priorities for a species. Small populations are at risk of going extinct because of demographic stochasticity ...
