Genetic rescue is seen as a mitigation strategy designed to restore genetic diversity and reduce extinction risks in small, isolated and frequently inbred populations. [1] It is largely implemented through translocation, a type of demographic rescue and technical migration that adds individuals to a population to prevent its potential extinction.
Evolutionary rescue is distinct from demographic rescue, where a population is sustained by continuous migration from elsewhere, without the need for evolution. [13] On the other hand, genetic rescue , where a population persists because of migration that reduces inbreeding depression, can be thought of a special case of evolutionary rescue ...
Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
The rescue effect is a phenomenon which was first described by Brown and Kodric-Brown, [1] and is commonly used in metapopulation dynamics and many other disciplines in ecology. This populational process explains how the migration of individuals can increase the persistence of small isolated populations by helping to stabilize a metapopulation ...
Genetic pollution is a term for uncontrolled [1] [2] gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", [3] but has come to be used in some broader ways.

Definitions of an ESU generally include at least one of the following criteria: [1] Current geographic separation, Genetic differentiation at neutral markers among related ESUs caused by past restriction of gene flow, or; Locally adapted phenotypic traits caused by differences in selection.
