Migration

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Gene Flow

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Cytoskeletal Coordination in Cell Migration

Cytoskeletal Coordination in Cell Migration

A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...

Transport Number

Transport Number

The transport number is the fraction of the total current carried by an ion in an electrolyte solution. It is defined as the ratio of the current carried by a specific ion to the total current flowing through the solution. The transport number, t, is central to understanding ionic mobility, which describes how fast an ion moves under the influence of an electric field. This link connects the physical behavior of ions in solution to the chemical processes that occur during electrochemical...

Cell Migration

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Cell Migration

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Area of Science:

Population Genetics
Human Migration Studies
Ancient DNA Analysis

Background:

The Baltic Sea region exhibits complex population dynamics due to historical migrations and genetic barriers.
Understanding its genetic landscape is crucial for reconstructing European population history.

Purpose of the Study:

To analyze the population history and genetic structure of the Baltic Sea region.
To investigate the impact of various migration routes on the region's genetic makeup.

Main Methods:

Analysis of mitochondrial DNA (mtDNA) and Y-chromosomal data from over 1200 individuals.
Genotyping of Y-chromosomal biallelic polymorphisms and STRs.
Sequencing of mtDNA coding region polymorphisms and the HVS1 region.

Main Results:

Populations surrounding the Baltic Sea demonstrate significant genetic similarity.
The Baltic Sea served as a key corridor for both cultural and population movements.
Divergent impacts from Central European, Volga-Ural, and Slavic migrations were observed.
Genetic drift amplified genetic differences, particularly in northern populations.

Conclusions:

The Baltic Sea region's genetic similarity underscores its historical role as a migration highway.
External migration influences and genetic drift have shaped distinct population genetic profiles within the region.
The study discusses potential origins for prevalent haplogroups, including those from Iberian refugia.
