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.
Revive & Restore is a nonprofit wildlife conservation organization focused on use of biotechnology in conservation.Headquartered in Sausalito, California, the organization's mission is to enhance biodiversity through the genetic rescue of endangered and extinct species.
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.
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 ...
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 ...
Synthetic rescue (or synthetic recovery or synthetic viability when a lethal phenotype is rescued [1] [2]) refers to a genetic interaction in which a cell that is nonviable, sensitive to a specific drug, or otherwise impaired due to the presence of a genetic mutation becomes viable when the original mutation is combined with a second mutation in a different gene. [1]
Outbreeding depression is a risk that sometimes limits the potential for genetic rescue or augmentations. [1] It is considered postzygotic response because outbreeding depression is noted usually in the performance of the progeny.
This reduction in genetic diversity was correlated with defects that include lower sperm quality, abnormal testosterone levels, cowlicks, and kinked tails. [16] In response, a genetic rescue plan was put in motion and several female pumas from Texas were introduced into the Florida population.
