Patterns of Evolutionary Diversification in a World‐Significant Hotspot of Salmonid Diversity: A Study of Landlocked Salvelinus Fish of the Kronotskoe‐Uzon Area, Kamchatka

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We have examined the phylogenetic relationships, genomic structure, admixture, and historical gene flow among the endemic charrs from the Kronotskoe‐Uzon water system in Kamchatka, in order to reconstruct their evolutionary history. We found that this unique diversity formed in the post‐LGM—Holocene time as a result of several waves of Salvelinus malma

Are there Gender-specific Preferences for Location Factors? A Grouped Conditional Logit-Model of Interregional Migration Flows in Germany [PDF]

open access: yes
The article analyses the question whether women and men differ in their tastes for location factors. The question is answered by quantifying the impact of location characteristics on interregional migration flows across Germany.

The determinants of the recent interregional migration flows in Italy: A panel data analysis [PDF]

open access: yes
The present study investigates the determinants of interregional migration flows in Italy in the light of the upsurge occurred in 1996, after two decades of decreasing internal migration rates.

Internal migration: a review of the literature [PDF]

open access: yes
The interest of interregional migration flows in economics covers two important aspects. The first aspect concerns the role played by the main macroeconomic variables in determining the intensity and the directions of the migration flows.

Describing and projecting the age and spatial structures of interregional migration in Italy

open access: yes, 2005
A multiplicative component model is applied in this paper to present a simple, yet powerful, framework for analyzing and projecting internal migration flows.

Determinants of internal migration in Kazakhstan [PDF]

open access: yes
In this paper we analyze the determinants of interregional migration in Kazakhstan using quarterly panel data on region to region migration in 2008–2010. To the best of our knowledge this is the first study on interregional population flows in Central Asia.

Using Age and Spatial Flow Structures in the Indirect Estimation of Migration Streams

open access: yes, 2005
This paper presents a modeling strategy for describing and estimating interregional migration flows. The categorical log-linear model is used to demonstrate various approaches to estimation, including direct and indirect methods.

Migration Dynamics in Western and Southern Africa. Introductory Article.

open access: yesNordic Journal of African Studies, 2017
Migrations have occurred throughout human history. Human migration generally refers to the movement of people from one place or state in the world to another for taking up permanent or semi-permanent residence, usually across a political boundary.

APPLICATION OF «BIGDATA» IN AN ASSESSMENT OF MIGRATORY PROCESSES

open access: yesВестник университета, 2017
Today the statistics of migratory processes has a number of shortcomings. Questions of mistakes in the account, a problem of illegal migration, weak methodological base of an assessment of interregional and intraregional migration.

Using age and spatial flow structures in the indirect estimation of migration streams

open access: yes, 2007
This paper outlines a formal model-based approach for inferring interregional age-specific migration streams, in settings where such data are incomplete, inadequate, or unavailable.
