在群体遗传学中,美国遗传学家Sewall Wright在两篇标志性的论文中引入了有效群体大小这一概念。有效群体大小可能有两种定义方式,即方差有效群体大小(variance effective size)和近交有效群体大小(inbreeding effective size)。两种定义由F-统计衍生而来并紧密相连。
群体有效大小和留种方式影响保种的效果。
Effective population size and breeders selection manners affect the effect of breeds conservation.
下层叶片获得的有效辐射量与群体上空的有效辐射总量及群体自身的叶面积大小分布密切相关。
That effective radiation obtained by low leaves correlated closely with both the total available radiation over the colony and leaves distribution of the colony itself.
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.
