Evolution of Migration in a Periodically Changing Environment
The American Naturalist, 2011The ability to migrate can evolve in response to various forces. In particular, when selection is heterogeneous in space but constant in time, local adaptation induces a fitness cost on immigrants and selects against migration. The evolutionary outcome, however, is less clear when selection also varies temporally.

The North Carpathians at the beginning of the Migration Period
Antiquity, 1991The problem of identification of the earliest Slavic settlement in central Europe drew researchers’ attention to the archaeological finds of the Late Roman and Migration periods.

2008We have begun to see how periodical productions in small nations with uncertain audiences produce genre formations that become strained in the search for readership and in efforts to differentiate themselves. Scottish periodicals adopt familiar genre patterns. However, they appear to experience even more acute genre instability.

Disturbances of Late Neuronal Migrations in the Perinatal Period
Archives of Pediatrics & Adolescent Medicine, 1987Abnormal neuronal migrations in the developing human brain are generally thought of in the context of early gestational events induced by genetic factors, teratogens, or infections. Although the major neuronal migrations that form the cortical plate occur by the 16th week of gestation, late migrations from the germinal matrix into the cerebral cortex ...

The Myth of Managed Migration: Migration Control and Market in the Soviet Period
Slavic Review, 1995The former Soviet state openly and directly manipulated patterns of economic development and the allocation of social resources in order to influence individual-level demographic decision making. In perhaps the most notable example, the state, through an internal passport system and limits on central city registration, attempted to regulate patterns of

Period and cohort measures of internal migration
Population, 2019La migration est rarement analysée selon une perspective de cohorte, ce qui n’est pas le cas pour la fécondité et la mortalité. Cette étude montre comment utiliser une méthodologie démographique standard pour étudier la migration interne en associant période et cohorte au niveau de la population.
