title: [Genetic and ecologic study of aboriginal inhabitants of the Siberian northeast. III. Demographic structure of three modern population links of Yakutia].
abstract: Demographic data of genetic interest were studied in three separate populations of Tungus-speaking Evens. They are characterized as expanding populations, rather as a result of migration and admixture, than due to natural increase. The mean and variance of livebirths per female, whose reproduction was completed, were 7.23 and 13.07, respectively. The Crow's index of the opportunity for selection (It) and its components (Im and If) were found to be 0.62, 0.30 and 0.25, respectively. The values of Im and If appeared to be essentially lower than those previously found in other northern populations.
