Migration

8.1K
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 Flow02:39

Gene Flow

30.7K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Cell Migration01:19

Cell Migration

6.1K
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.

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.

Quantifying Work

18.4K
As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.

Transport Number01:31

Transport Number

230
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...

Summary
This summary is machine-generated.

Global migration flows remained stable at 0.6% of the world population since 1995, with major movements observed between South/West Asia, Latin/North America, and within Africa. This study provides comprehensive bilateral flow data.

Area of Science:

  • Demography
  • Sociology
  • International Relations

Background:

  • Existing data on international migration inadequately represent current global flow patterns.
  • Comprehensive, bilateral migration flow data are crucial for understanding global population movements.

Purpose of the Study:

  • To present a comprehensive dataset of bilateral international migration flows between 196 countries from 1990-2010.
  • To analyze the intensity, patterns, and trends of global migration flows.

Main Methods:

  • Utilized bilateral flow data for 196 countries spanning two decades (1990-2010).
  • Analyzed migration intensity as a percentage of the global population over 5-year intervals.

Main Results:

  • Global 5-year migration flow intensity has remained stable at approximately 0.6% of the world population since 1995.
  • Identified major migration corridors: South and West Asia, Latin to North America, and intra-African movements.
  • The data facilitate contextual interpretation of migration trends for individual countries.

Conclusions:

  • Global migration intensity shows remarkable stability over the past two decades.
  • Bilateral data provide essential context for understanding national and regional migration dynamics.
  • Significant regional migration patterns persist, particularly within Asia, the Americas, and Africa.
