What is the term for the movement of individuals into an area?

The term that refers to the movement of individuals into an area is immigration. This process involves organisms moving from one location to another, typically to settle in a new environment. Immigration can affect population dynamics, genetic diversity, and the overall ecosystem of the area being entered.

This term is distinct from others related to movement. While migration refers to the broader movement of individuals, often seasonally or cyclically, it does not specify the direction or purpose. Emigration specifically describes individuals moving out of an area, while invasion usually pertains to non-native species entering and establishing themselves in a new area, often leading to ecological disruption. By understanding these definitions, it becomes clear that immigration is the appropriate term for individuals coming into a specific location.
